I have an HTC touch pro with the latest verizon ROM.. this is the second time that DNS has stopped working. i can go to websites by numeric IP but not by name. no applications work that use a servers name.. ie:google maps: aim..
last time i fixed it by reinstalling the rom and redoing my whole phone but i dont want to do that again just for it to happen again next week.
I have an IP utility on the phone and the phone has dns servers listed .. it just isnt performing dns. Last time ity happened i tried manually adding open dns servers and it still didnt work. Please Help.
Nevermind I figured it out. The Phone was holding the wifi ip address/dns info from when i had used wifi earlier. i went to settings.. connections.. wifi and changed from a specific IP address to obtain address automatically and now it works fine.
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.

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.
anyone of you here using a proxy server in a university? when i move to a different building in the same university, i cannot browse anymore because it says "authentication via proxy server was unsuccessful".
our proxy server does not require auntentication.
android 3.2 from our tablet has already a built-in proxy settings, why is this happening to me when when i move to a different building with the same proxy server?
any help from this will be greatly appreciated.
thank you in advance.
I don't have any issues in my University using the WiFi =/
i dont know why it is happening to me? the tech from the university said maybe its due to number of devices accessing the wifi proxy at the same, thats why i cannot connect. but i had my rooted lg optimus black before and its running smoothly in the university's proxy server!
i think there is something wrong with android 3.2's wifi proxy?
There are wifi-related issues with some of the Galaxy Tab 7 Pluses, (namely the SOD,) but this one is new to me. I've never experienced it. Truth be told, the tech could be correct. The proxy server might have been refusing connections due to heavy load. Even if you think your phone and tablet are connecting at the same time, the phone could have made its request earlier and been the last allowed device, or if you connected after, could have taken up a spot that was just vacated by another device.
My question is then, is this an ongoing issue? By this I mean are you having this issue multiple times in the day, where your phone can connect just fine, but your tablet is throwing that error message?
thank you for your reply, rkmj!
yes, this is an ongoing issue up to now! i have been experiencing this for over a month already. when im the main library i can easily connect at the first time. but when i move to the other buildings within the same proxy server, with definitely different access points it always says:" authentication via proxy server is unsuccessful". i am using my rooted lg optimus black with this same positions in the university before, and it works flawlessly, so i doubt if it is with the heavy load?
so is there something wrong with the proxy setup of honeycomb 3.2?
Well, another strange issue with my brand new MM3.
Global rom there.
I noticed that two (and only two) apps ("Ip cam viewer" and "Vera Mobile") are perfectly working when connected to WiFi but as soon as I switch to LTE, they stop working.
The apps are launching, but says that there is a connectivity issue. Of course, I checked the regarding parameters (i.e. ip public adress, port, password...) on booth apps but as those paramaters perfectly works with another phone, I really don't understand what's this issue.
No problem with youtube, or gmail, or any other app...
Anyone can help ?
Thanks
Am I the only one facing this issue ?
This is probably to do with your Vera app settings. I don't use the Vera Mobile app, I'm still using Home Buddy, but the app communicates through the external MIOS servers unless you're in local mode (on your home wifi). Also, check the IP address of your Vera (you really need to make it static, or reserved on the router), otherwise you'll have difficulties in local mode if the IP address ever changes.
The other thing you can try is logging into MIOS through a browser session and check that it works, if not then you know you have an issue between the MIOS servers and Vera.

Thanks for your reply !
It works while logging through browser.
My vera's ip is fixed.
Furthermore, my ipcameras also have fixed ip adress, and the problem is the same with the "ipcamviewer app".
Every other apps are perfectly 4G working so... WTF ?
As I said, it's nothing to do with 4G or the Mix 3, it's because the MIOS server is unable to reach your Vera through a remote connection. I can't log in to Vera Mobile to take a look because I don't have the login credentials for the account I created when I tried to "upgrade" to a Vera Plus, but to resolve the problem you're probably going to need to talk to MiCasa Verde support. If you want to prove it, try connecting to a wifi network other than your home network and see if you get the same problem as when on 4G.
Maybe I'm not correctly explaining my problem.
First, I've got a Veraplus.
Regarding Vera Mobile app :
- local wifi : no problem
- other wifi network : no problem
- 4G with web brower : no problem
- 4G with VeraMobile app : issue
--> so I think it means that the MIOS server is able to reach my VeraPlus through a remote connection, right ?
Second :
Ipcamviewer app
Local Wifi : no problem
Other Wifi network : no problem
4G : issue
So I really really think that the problem comes from the MM3, especially since I previously owned a Mi Mix and there was no issue at all with both apps Ipcamviewer and VeraMobile...
All my apps were restored from my google account, so is it possible that the problem comes from a "cache" I should delete (restoring apps include ip adress, port, login and password).
If so, how to "clean the cache" ?
You can clear the cache on the apps by long pressing (not sure if this works on MIUI) and clicking info, then clearing storage. Alternatively, find the app list in Settings and do the same thing that way. This isn't going to be a MM3 problem. I have the same issue occasionally with Home Buddy and it's always a MIOS server issue. The connection to the MIOS server is actually the other way round, it's an outbound connection from the VeraPlus to MIOS, so you may also want to check that the Vera unit can get out. I couldn't live with UI7 on the Plus, so it's still sitting in the box and I stayed with the Vera 2.
Ok.
Let's suppose that there were a problem with the MIOS server.
BUT :
That does not explain why there would be a connectivity problem with the IpCamViewer app...
There have been tons of IP cam related problems for months, on all devices. I use YiCams and it works perfect on iOS. But on our MM3 and also Note 8, they don't work right at all. I see the same issues with all the major IP cam services. Xiaomi told me it has been some sort of persistent server problem, but why its taken 2 months so far to fix, I don't know.
My "best" guess is maybe they are all using the same push provider and/or 3rd party framework, and it has **** the bed (they all seemed to upgrade their apps around the same time, too, and they all look suspiciously similar)

Very strange answer from Xiaomi considering the fact that I never had this issues with my previous Mi Mix... Which is still perfectly working in 4G with both IpCam and Vera Mobile apps...
Still unsolved.

More than words, this is what happen with wifi (first pic) and with 4G (second pic)
