I rarely post questions because most that I have had have been answered already and I can find what I need through searching.
However the amount of apparent confusion in the questions and answers on this subject has made it impossible to figure this out.
I cannot reliably connect via wifi on my Wizard running XDA Mobile 6.
Problem:
1. Wizard connects to Wifi, but does not correctly get DHCP.
Okay, a pda is pretty useless as a wifi device if it can't receive a dynamic address, but I set up a static IP (on the Wizard) to work with my router, and deferred diagnosing this until after I actually have wifi working at all.​2. Wizard cannot seem to choose a DNS server.
It apparently tries to use the GPRS dns server to resolve addresses, and can succeed, but this is slow. If I disable the phone it uses the DNS I entered (my wifi router). and works precisely as it should, resolving domain names almost instantly, just like the other wifi devices on my network. With the phone turned on the DNS address seems to be ignored​
Is there someone out there who can address this problem? Maybe I need a primer in the serpentine methods Windows Pocket PC uses to configure itself to connect to networks, because it certainly doesn't seem the least bit logical from this writer's perspective.
Thanks.

Yes, I had the same issue with most 6.0 ROMs here. But TNT 6.0 ROM works without changing DNS manually. Haven't checked the root cause is ...... You might install TNT ROM to see whether it resolve your issue.
That's some kind of DHCP problem.
I don't have it with my cooked ROMs.
When DHCP is used to get an IP address, it also gets the DNS servers sent back in the same response packet. So if you disable DHCP (or it fails) you need to manually configure both it and the DNS addresses.
Exactly my point.
It's clear that the problem is a DHCP client failure. There are plenty of posts here saying things like, "try a different ROM" etc. The information I am looking for is how to fix it.
Uh, try a ROM that doesn't have the problem?
The ones I've run (including my own cooking) work fine.
oops- double post
I was sort of hoping for a registry key to edit or other setting...
DHCP is working, for example on Remote NDIS-host (activesync connection), so it seems likely that there might be another solution.
I will have a look at your ROM, Genesis3.,
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.

When I try to connect to a secured wifi it just sits here at Obtaining IP address... passcode is correct or it doesn't make it this far. It does the same thing if I try to tether to my N1. Works fine if no encryption is used... Any one else? I remember having this problem with my N1 a long time ago, but it was fixed eventually plus I just got a new router... My N1 and laptop connect to everything fine.

I have the same problem and a guy from LG wrote me this:
"The issue seems to be that if the router does not send a server ID to the phone it will reject the IP address offered. This is not limited to LG phones, but is an Android issue."
The solution is to enter the internet parameters manually through "use static IP". Does anyone know what parameters we need to type in "IP Address", "Gateway", "Netmask", "DNS1", "DNS2"? Thanks!

hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"
Hi,
Why am I getting this notification for the 1st time in approx 2 months that have got a OPO, despite that am connected to WiFi?
Hoping to hear from you experts.
Thanks.
This sort of thing normally pops up when the WiFi network wants you to go to some sort of page, this is usually for a login to free WiFi hotspots, I assume this Dlink is your WiFi? Perhaps it wants you to open this page to change a configuration or login. This doesn't seem to be Android related at all but more to do with your router, could you try tapping on the notification and screenshot the page it opens, if any.
He's right. This looks like a router setting that you might have turned on like guest mode.

Thanks for replying, appreciate your expert views.
DLink is my WiFi and not a hotspot WiFi, never occurred earlier.
When I tap on it, G chrome takes me to 173.194.35.96/generate _204
Google results of this IP......173.194.35.96 which is Spy-IP.com
and Google has different results for this 173.194.35.96/generate _204
It never happened earlier in the past 2 months.
Been using the same OPO and same WiFi.
Any solutions to resolve it?
Thanks again and Best regards!

This is a router setting then, that page is some sort of login. Perhaps guest mode has been enabled on your router? Try this:
Settings>Wi-Fi>Modify Network>Show advanced options> Change DHCP to Static. Here, find the box that says Gateway and note the IP here. Now change Static back to DHCP and close this menu.
Go into the browser on your OPO and put in this Gateway IP, this will take you to the router config. The login for this is usually on the bottom of the router, otherwise the default can be found by searching the router model number, try finding a guest mode setting and turning it off - I really don't know... You can also change your WiFi name and password here if you like
I can't really help you any more than that.

Glad to hear, I am strongly advising against the factory restore. This is a feature of Android, although it is strange for it to be happening in this circumstance there is nothing it will achieve.

1. Changed router's password.
2. Guests mode is Off.
3. All apps working with WiFi except GMail and GPS.
4. Still see the notification.
5. Should WPS be Enabled, it is disabled at the moment?
6. You don't recommend a factory reset what about a re flash of 30 OR?
Thanks.
Your phone is working fine, it seems you have triggered some sort of bug in Android's WIFI login detection.
The system works by accessing DNS and check if the resulting IP is owned by google.com or some network-internal redirection/replacement by a login page.
Now, the IP 173.194.35.96 is owned by Google, so the DNS lookup obviously worked perfectly but for some reason the phone gets an unexpected answer from that server. Which makes me guess to one of the 2 following options:
a) one of the computers in your network is infected and Google keeps showing the "Prove you're human" captcha window on requests.
b) your provider is replacing failed DNS lookups with it's own "helper" page which for some reason is making Android trip. If possible, change the DNS servers in your router to either OpenDNS or Google DNS.

That's entirely your choice. However I would only recommend enabling it if it's the "Push to WPS" method and not constantly on - WPS is broken and depending on your router it takes between 1 to 10'000 attempts (1 second to ~ 2 hours) to break into your WIFI. Not good!

For example,
The WiFi connects with no internet, DHCP address of 192.168.2.2 provided. I then manually change phone's IP address to 192.168.1.2 to access devices on a 1. subnet. The result? My connection repeatedly cycles. Traffic does briefly pass through but the cycling makes it unworkable.
My only workaround is to set DHCP on the router to the subnet I need to be on. If anyone's curious, this is just to configure Ubiquiti radios and to occasionally access backhaul equipment. I like being free of a laptop whenever possible.
I've tried tinkering with every modem related setting I can find to no avail. I'd like to grab proper logs but the app I got wasn't very helpful. This is a bit out of my wheelhouse unfortunately.
Has anyone dealt with this and found a solution? This is on a Pixel 7. Never had this problem on my S22.
I hope someone can help. Thanks!
Hi there. We've recently faced the same issue, so I'd like to know if you've solved it.
Hey there, thanks for sharing your experience with this issue. I can definitely understand how frustrating it can be when things don't work as expected. It sounds like you've tried a few different things already, but have you checked out https://routeripnet.com/ip/192-168-8-1/ for any troubleshooting tips or solutions? It might be worth taking a look to see if anything there can help. It's also possible that there's an issue with the app you're using. Maybe try a different one to see if that helps. Good luck, and let us know if you find a solution that works for you!
