School wifi problem

Just got my Samsung Captivate about a month and I got my wifi connected to the school network, but when i open the broswer or any apps need internet i didnt get any connections? at the first week it works.. and when connecting to the school wifi it should be come out with the school login page,, then the internet will work.. however the wifi is connected doesnt matter how strong the wifi singal is.. it just cant load and cant bring me to the login page..
I really need help..
and the wifi works everywhere.. except my school...
btw my friends iphone 3gs works..

I am also at college and have had the same problem. the best reason I have found is the phone itself. half of our wifi is an older standard that does not work on the phone. it shows up as wep and i can not get it to recognize it as 802.1x . in my tinkering I have also messed up the wifi that was working.
long story short it probably won't work. I have spent a long time trying to get it to work with no luck

Hello to both of you,
I also attend a college with an 802.1x connection and the captivate supports most of these networks; however you will probably need to configure the network settings manually (usually retrievable on your schools IT site). If you dont mind digging up your settings I would love to check to see if I can configure your phone.

FYI, you might be having a problem similar to what's seen in this post.

I definitely had this problem today. It appeared connected but no web pages would load. Going to have to investigate further. Why can't things just work

I know my school recently implemented some new security certificates that you must agree to before logging in, has anything like that changed for you? My wife's Aria is running 2.2 and can log into the school network, but my captivate cannot. It is frustrating I know.

Seems some colleges and universities are noticing issues with android devices letting the DHCP leases to expire but keeps using the IP address assigned instead of requesting a new one.
See the following links.

I actually have similar issues with my Belkin wireless router at home. My laptops and other wireless devices have no problems connecting or re-connecting but the Captivate just refuses to re-connect after the connection was terminated. Even after resetting the router, the phone just keeps trying to use the same IP address for some reason.
The only way I could get it to reconnect is to either reboot the phone or to remove the AP entry which is a pain especially if you have wireless passwords.
Hopefully someone with better insight into how Eclair and Froyo handles WiFi can come up with some fix.

more solutions?

I believe the new 2.2 firmware solves this issue. I too am at College and my captivate FAILS to actually access the internet through wifi unless I statically assigned the IP.
I just updated to Froyo and it connected instantly. I'll have to do more testing to make sure, but I think Samsung finally fixed it.

captivate wifi issue at school
i just got Galaxy S (Captivate) and wi-fi is giving trouble.
when i tried at a university campus, it gives error and says can't open and try again later. it is like, i get connected to the network, IP and DNS and everything is generated. But when i open browser to open a website, instead of taking me to login page it gives the above error.
here is what i get when i try to open a website.
'web page not available'. the page might be temporarily down or it may have been moved permanently to new address.
here are some suggestions:
- check to make sure device has signal and data connection. (I made sure it is connected to wifi)
- reload page later. (i tried after 5 mins, same result)
- view cached copy from google. (doesn't work either)
i am not able to understand why is this happening. i tried restarting the phone after connecting to wifi but no luck. any pointers?

Sounds like they use a portal system which requires logon and doesn't play nice with the Captivate's browser. Unfortunately many such portal systems are written poorly and I've even seen some that only work with Internet Explorer.
You could try a different browser on the Captivate. Dolphin allows spoofing assorted User Agents, which might help.

Hey guys, I have the same problem connecting to m school's network login page. It would say connected but the website always says cant be found. But the good news is that I found a way to connect to it manually! What you need is your captivate and friends iphone 4 or 3gs. First have use your friends iphone to connect to the wifi and then go into wifi settings. You should see 2 DNS address, Ip address, netmask (subnet mask) and router address. Now jot those addresses down except the ip address. Go to settings->wireless and network->Wi-Fi settings->now tap the bottom left button under the samsung logo and click advanced. Now check use static ip. Do not enter anything for your ip address just yet (we will do this last). Now enter router address into gateway, subnet mask into netmask, DNS1 to DNS1 and DNS2 to DNS2. ok when you are done click back and tap the network you want to connect to. Once you are connected jot down your ip address by taping the network once more. now go back to where the static ip was and input the ip address you just jot down into the ip address underneath use static ip. Disconnect and reconnect to the desired network. You may have to do this a few times or reboot your phone. This has been working for me so far around different buildings but with the same school network connection. I hope this helps cheers!

Yeah, my school uses the Bradford dissovable agent. Funny thing is, some connections work perfectly, others not at all. Technically none should work, and sometimes I feel that maybe I should tell them that sometimes somehow it is possible to bypass the whole agent thing- but why rock the boat just yet

Does it need a proxy to work? If so, this app is amazing.

I figured it out a month ago, and it is actually petty easy. But you really have to change ip address manually, usually just the last number.

Got my GT7+ yesterday and have a couple questions. Brightness? WiFi?

Edit: This is the Galaxy Tab 7 Plus 4G w/ TMobile...
So far I am loving it. I have had a plethora of Android tablets, including the Galaxy Tab 10.1 (until yesterday), and the original 7" Tab. Here is an issue I have not run into thus far...
Issue 1: I like my brightness settings to be %100 all the time. I always (almost) have a power cable with me, so I'm not worried about the drain. I have the auto setting turned off as to keep it from adjusting on it's own. However, everytime I open the status menu with the brightness slider, it is down to about %90-%95. I can't get it to stay on full. Also, and even more annoying, every time I open the browser, the brightness drops to like %30'ish and I have to open the status menu and slide it back up. The browser is where I REALLY need the full brightness the most, and it's the biggest issue.
I noticed this out of the box, adjusted settings, nogo, so I factory reset, and same issue. This is leading me to believe this is just a setting or something I am missing. Any ideas?
Issue 2 (THE BIG ONE): This Tab 7+ can't see my work wifi. It connects to my wifi at home just fine (did last night at least), which is also WPA, but it doesn't even see the one at work. It acts like it isn't there. In fact, and this is probably important, it is not seeing any networks up here, and there are at least 10-15 that should be visible from my location in the building (all but a couple from other companies). My G2x (Android 2.3) is connected to my work wifi just fine, and it sees all the others around us, the the Tab 7+ right next to it sees none. I also turned on the wifi router on my phone, it will not see that one either. I've verified the wireless is enabled, as well as turning it off and on multiple times and many reboots, nogo... I need it to hit the wifi at work and home so it isn't sucking my 4G data, so this is a big issue for me.Any ideas? I'm at a loss...
Also, to answer before it's asked: Nope, it's not rooted. I may do this at some point (as I do most of my devices), but for the moment I want to leave it stock and not mess with it. These issues seem like they should be resolved/nonexistant in the stock ROM, so I shouldn't have to root to fix them. Please tell me if this is incorrect...
Thanks for any help, sorry for the long post...
(pardon typos, I'm at work and multitasking, no time to proofread)

on the brightness broweer tip. use a different browser. its a known issue that the stock browser automaticaly dims the screen.

Thank you... You're right, it doesn't happen in Dolphin, however I am one of those weird people the really prefers the stock browser...
The biggest issue is the wifi not showing up. I am updating that issue with more info now...

what channel is the wireless network on? i had a similar problem on my windows laptop, it cannot see the wifi.. turned out that my wireless card(the driver actually) cannot see any wireless network beyond channel 12.. who knows you're having the same problem, might worth checking.

Ours is on 6... Thanks though

for me it was the opposite, it could see my home wifi, but not my work.
only was to solve it was to setup a static ip at work for the GT7...
I called samsung, they said its a problem with some routers. No eta on fix other than static IP.

Just to chime in - I also have the same problem connecting to my work wireless network but I think because it uses a SEPARATE authentication scheme.
The way my office WLAN work is like this:
1). Connect to the WLAN with SSID "Office", no encryption password required
2). Once the Tab is connected, it WILL receive an IP address
3). Open up a browser (Dolphin, etc.) and try to go to any website (Google, etc.)
4). Instead of going to the website I typed in in no. 3, an authentication page will show up
5). I need to enter my Windows AD account and password
6). If its successful, then I can start browsing the Internet (but not going to the Internal network, that requires VPN access).
Step 3 is where the Tab FAILED to do so. It just doesn't want to get redirected to the authentication page.

Yep, same way for me at work. OP did you try to manually add the wireless info vs letting the tab "find" the access point?

Also, here is a strange thing. About 2 hours ago it notified me there were wireless networks in range, and then showed me 2 random networks from another office. Suddenly, it saw nothing again. Then about 5 minutes ago, while I was in the bathroom ( ), it suddenly showed me ALL of the surrounding networks. Yay! I tried to connect to the one I use, it took my password, but never even attempted to connect. Then, they are gone. Now it doesn't see them.
What. The. Fuuuudge.

WiFi connectivity issues

Just received my Nexus 5 today and I'm noticing some strange connectivity issues while on WiFi. Some apps would complain network is unavailable, Facebook would load with no pictures, etc. This happens randomly, sometimes after few minutes others - an hour(s). Rebooting the phone or even cycling WiFi off/on usually recovers it, until it happens again. Cellular data works fine all the time. It can't be the WiFi network I'm connecting to as I have a myriad of devices that have worked and continue working without any problems.
I tried 3 other WiFi networks (different routers) with different configurations of encryption as well no encryption, switching between 5GHz, 2.4GHz, no matter what, problem occurs sooner or later.
Noticed on Google support forums few users describing exactly the same issue, surprised I didn't find reports here on XDA. Maybe not many people got their phones yet.
Anyone else getting the same "treatment" from their new Nexus 5?
Sent from my Nexus 5 using Tapatalk

I am seeing exactly the same thing. Wifi will work great, then all of a sudden, nothing. Stays that way for a couple of minutes, then all of a sudden it works again.

How many bars does the sifi icon show ?

Number of bars doesn't matter. I can have full bars sitting a meter from the router and issue would happen anyways.
I tried playing with WiFi optimizations in advanced settings to no avail unfortunately. Hopefully this is a bug that Google can quickly fix with a software update

Same here. Got my N5 yesterday and experienced the same at home. Same for my brother.
Hope that gets clarified soon. Not the nicest feeling having a new phone with that (or any) kind of issue...

Yes, my N5 started doing the same on my home wifi connections (using Apple's Airport Extreme 2.4/5GHz router).
The Playstore or Youtube apps would not display images or take forever. When I switched wifi off those apps worked fine.
I got it working again when I "forgot" my wifi setting for the 2.4 and 5Ghz channels then reconnected to the 2.4. I'll let that run for a day or so then try activating the 5Ghz.

Hmmm... This may have been what was going on here...

Hmm - no I don't think that's the one. Phone connects fine, just over time randomly does this thing with the connectivity issues.

--EDIT
OOPs my mistake...
I looked in Setting/Wifi/Advanced ...
I turned OFF "Avoid Poor Connections"
and everything seems to work the way i want ( when i tell it to go to Wifi, it does that )
--EDIT end
i added star to this issue because of same problem . If enough stars get added Google may get on it.

(Didn't know if I should create a new thread for this as it is a wifi issue but seems to be soemthing different than what the OP decribed, my issues are related only to playstore app downloading)
I too am having terrible wifi issues on my new Nexus 5. But mine are different from those described here I think. Whenever I cycle through the wifi, turn it off and on again it doesn't fix the problem (not temporarily and ofc not permanently)
When browsing the web, the play store and mostly everything it works great and is very fast, BUT when downloading or updating an app the wifi speed is practically non-existant.
Sometimes showing that it will take 25 hours to download a 25mb app :S
This while my Galaxy Nexus on the same wifi network is as speedy as ever.
I have tried factory resetting my Nexus 5, I have cleared the cache and data of the play services app and of the play store app, I have tried changing the wifi bands (from auto, to 5 to 2.4 and back to auto), I have turned off the wifi optimization, but none of those things helped. I even tried some DNS HSPC wifi settings thingy I read here
That didn;t help either.
I have unplugged my router and replugged it in but that didn't help either.
I literally had to leave my brand new Nexus 5 downloading all night just so that it could install the apps I wanted on it. So far for playing around with the phone on day 1
What makes it even weirder is that occasionaly the wifi issues resolve itself and I can get good download speeds for several seconds or sometimes up to a few minutes, but then right after it is straight back to crap speeds. Some other reported that only while making a portion of the map available offline in Google Maps their app download speeds were great, but that didn't work for me either.
I don't know what to do and if it is a hardware issue or a software issue. Please help me.
Below some info that might be useful to helping me solve this.
White Nexus 5 32GB
Bought from US play store
Shipped to and using it in the Netherlands
Currently does not have a SIM card inside (that is still in my Galaxy Nexus till the wifi issues are resolved)
Unrooted, only installed the mandatory update during the setup
All apps downloaded are apps that are also on my Galaxy Nexus which works without a hitch
Any and all suggestions/ideas/help are welcome

I think the problem somehow related to DNS. I found that if I configure static IP settings and point DNS to Google's instead router's, things work normally. I reconfigured my router to advertise 8.8.8.8 and 8.8.4.4 as DNS servers for the DHCP and now for over 24 hours I haven't experienced the disconnection issue.
If your router cannot be reconfigured, try assigning static IP settings and Google's DNS to see if it helps.
I still believe that's a software bug on the phone, we can't blame a device (the router) that has worked for years and works fine with everything else but the Nexus 5, being at fault.

I currently can't reconnect to my Wi-Fi at home as it's stuck showing the last scan I did some 40 miles away at a shopping centre earlier today.
Of course none of these networks are now present, yet all mine are shown as not found!
Guessing a reboot will fix it as toggling Wi-Fi didn't. Mobile data is working fine.

Not as tech as I want to be, so could you explain to me what the difference is in setting the DNS to Google's instead of routers? I have no idea what DNS is/does so what happens when you point it soemwhere else?

DNS stands for Domain Name Service. What it basically does is to translate those easy to remember names such as www.Google.com to the actual numeric address (also called IP address) of the server that serves that site on the Internet. Home routers almost always sport built-in DNS service to speed up name translation requests from internal devices. What I figured is going on on the nexus 5 is it "doesn't seem to like" some DNS servers. Works fine with some, doesn't with others. What happens is at one point, for whatever reason, it stops being able to translate names to addresses and as result "decides" there is no working connection as it fails to connect to the corresponding servers. Google hosts publicly available DNS servers with the easy to remember IP addresses of 8.8.8.8 and 8.8.4.4 which apparently Nexus 5 doesn't have problem working with. Once it gets "instructed" to use them instead router's, everything works fine.
At least that's what I figured is going on so far.

BTW, just found one small and very useful app that can display information about WiFi connection as well as DNS servers associated to it.

Thanks, but that wouldn't fix my issue right, because it doesn't explain why only play store downloads are terribly slow while the rest works fine.
Gave it a shot and at first it seemed to work, but after a short while the problem re-arose

DNS has nothing to do with weak or lost WIFI connections...
You can be perfectly connected, at full n speed to a WIFI AP without getting proper acces to Internet : THIS can DNS isue.
But in no way a DNS isue can leads to lost or very weak WIFI signal.
2 solutions are possible with Nexus 5 :
- WIFI module has the same badly coded shape as camera one...
- its hardware related wich, no need to say, could be the worst case...

I am having the same issue since day one. In fact it just occurred as I was replying to this thread. Mostly occurs when the phone comes out of sleep mode. However it will occur often and at random.

How to change DNS IP

I replied in another thread, but I think I'll give it it's post because many people are asking.
Took some crummy pics:
Home -> WIFI connection:
image (1).jpg
Device Network -> Wi-Fi Connected
image (2).jpg
Network Wi-Fi -> {select your active connection} In my case it is Leafs RULE!!_5G
image (3).jpg
Select Advanced options
image (4).jpg
Then select IP settings. In your case it'll say IP settings DNS. In my pic it says IP settings Static.
image (5).jpg
IP settings -> STATIC
image (6).jpg
Go through the IP settings and enter in a static IP, gateway, and DNS settings. Press save and then hope it saves.
You know it saved properly when "IP settings DNS" changes to "IP settings Static". In my case, it didn't pick up the new settings till the next day. Maybe after you save your settings, power cycle NP; go back into settings and see if it changed over to static. As with other things with the NP, try a couple of times.
I didn't change or add anything to my router. My router is still using my ISP DNS IPs.

Go through again slowly and double check. I had the same issue at first. I saw settings were saved in the wrong sections. I think there are bugs in this section when saving.

I kept having problem saving the dns 2. I key in a different ip address, but it kept reverting to the ip address of dns 1.

I've noticed this also, but this has not caused any issues.

Do you know if there's any Apps for easy switching DNS on the NP without Root?
I would love being able to switch between European and American Netflix, but going through all those steps to change DNS every time is a bit of a hassle :-/

The only step you have to change is the DNS IP. Yes, an app would be nice.

Don't you have to type in all the other stuff too every time? (IP, Gateway, Router IP etc.)
Last time I tried it didn't save any of it.

Think there is a bug, I also did not manage to save dns2. Some said have to wait for 1 day before nexus player reflect the new dns. IMHO, Lolipop is not ready for nexus player.

Very nice. Another option is you can use static IP overrides in your router, if it has them. I'm able to assign a static IP based on Mac address via my router that overrides the DHCP server. This is handy for devices where static IP setup isn't easily available (or not available at all). Not all routers can do this though.

No. You have to just put in the new DNS IPs for 1 and 2

qcom_rx_wakelock

So as you may guess, i am having trouble with the qcom_rx_wakelock, and no matter how much searching i do i can't find a solution. I am hoping someone here may be able to help.
It occurs only when wifi is turned on, (not currently sure about connected vs unconnected) and is responsible for causing large drain from Android System and Android OS.
I have tried a number of proposed solutions including: clean rom install (sultan's CM13 if it matters), changing radio, ensuring wifi scanning is turned off, and applying an iptables custom script in droid wall.
None of this has worked.
My knowledge of the wakelock is that it is to do with wifi: 1 hypothesis is it relates to broadcast/multicast pings constantly waking the phone, 2nd hypothesis is that it is to do with being on a large scale wifi network with unusual security (i am at uni). One person suggested (in a thread that i can no longer find) that a dev solved it by changing the wifi drivers in his kernel, but i cant do this unless i change kernel i guess?
Below are some screenshots of it effects. Any help in finding a solution would be greatly appreciated!

Get Greenify and ForceDoze from the Play Store. ForceDoze doesn't need any special settings, just enable it. With Greenify, go in and select apps that use data connectivity. This should minimize wifi wakelock.

I tried that and it made little/no difference, also tried amplify, but qcom_rx_wakelock is not listed. With regards to dose I use aggressive dose, I think this is the same? But it did not make any difference.

This is a quote from another forum:
That particular wake lock is triggered any time the phone is awoken from deep sleep to send or receive data on wifi. If you are having issues with just one particular wifi network, that is likely DHCP/dynamic IP related. There are reports of issues with certain wifi routers that are using dynamic IP addresses causing DHCP queries to constantly wake the device. The only known work-around is to set a static IP address or use a different router.

So, you could try setting the phone's ip to a static ip and see if this minimizes the issue.
Edit: Forgot you were on university's wifi, may not be able to set a static ip, unless you set the last 3 numbers to a very high number. Ex: 192.168.1.900, if the router(s) are set up to assign that high.

Ok, thanks! I have just come home today so will see if it stops on my home wifi, but will be back in uni on monday so will check the static IP idea then and report back, would your example address be appropriate, or do i need a more specific address?

The above ip is just an example.
Go to settings > wifi > 3 dots in upper right > advanced. now scroll all the way down and see what your ip is currently and write it down.
Go back to main wifi menu and long press on the connected wifi and choose modify network
Expand advanced options > tap ip settings > choose static > enter in the same ip you wrote down or change the last 3 digits and save
Note: when you tap on the box to enter ip, an ip will already be showing, just start typing and it will disappear.

Hi, this was quite some time back so i don't remember all the details of when exactly the problem stopped, but i don't have the issue any more. The only things to have changed are that i am now on jgcaaps CM14 as opposed to sultan, and perhaps the uni had changes things on their end? i don't know.
If you are having the same issue then try the things i mention in the first post, and the solution offered in this thread, and if that does not work then maybe change ROM/Kernel?
I'm afraid that is about all the help i can give

Hey!
I'm having the same issue (having WiFi on drains 2-4% per hour, turned it off last night, didn't lose one single battery percent in 7+ hours), how did you resolve the issue?

Mine was a hardware issue.
You can try to flash complete stock firmware "this is different" than downloading a Rom and flashing via TWRP.
