Stuck on "obtaining IP address". Fixes don't work...

So I got the dreaded "obtaining IP" loop. I searched and found others have this problem too, but not for the Nitro. Their fixes don't work for me.
I can connect to my friend's router just fine with his password. I also have 2 routers at my house, both have passwords. I can connect to one of them just fine, but the other doesn't work and that's the one I get better signal from! I'm 100% sure I have the right password and I know the router is working fine because everyone else can connect to that router just fine with their phone.

You're trying to connect to 2.4Ghz, not 5Ghz, correct? My Galaxy SII would connect to 5Ghz on my router, but my Nitro only connects to 2.4Ghz.

They are both identical routers in my house. They don't say the Ghz.

Which channel is the wireless set to?
Transmission Rate?
Channel Width?
Security Mode?
WPA Mode?
Cipher Type?
Let me know what these settings are, I'm using the D-Link DIR-825 here and it's working fine.

That's all Chinese to me. Where would I find this information?
All I know is my phone says its secured with WPA/WPA2 PSK
I really appreciate the help though

Log in to the router from 192.168.0.1
Click the setup tab, and then wireless settings on the left. Next click "Manual Wireless Network Setup" and you should see your settings on that page.

The nitro should support WPA2 just fine. Plain ole WPA is now fairly insecure and it is advisable to avoid using it if possible.

You are the man! So it works now. The other router that worked all along is off right now, but I'll check that out tomorrow.
What about my other family's phones for this router, will theirs work just the same as before?
The only thing I can think of that went wrong in the first place was that I didn't type in the right password. Even though I told my phone to forget it, since then I had the problem.

One thing I noticed about the Nitro and Wifi is that it's really picky when connecting to a router. The good thing is that the connection is very good once connected.

Wouldn't you know it. I haven't done a thing since yesterday and now it won't connect to the router that we fixed. I guess I'll play around with it some more. I can still connect to that other router just fine.
Edit* - I put everything back to how it was originally when it didn't work and now the phone connects to the wifi, weird. Its back on WPA2 and Ch.5 At least I know how to screw with it now!

Ya, I got this problem too. I get this when I root and then reboot (still rooted), dunno why. After I un-root and reboot, the problem goes away but I had to reboot the router too. In this whole procedure I never change the wifi access point setting, very very weird....

[Q] 5 Ghz WiFi impossible on Linksys wrt610n

Hello,
I cannot connect to my AP on 5 Ghz
It sees it, it asks for password, but then disconnect and reconnect endlessly
Any idea why
Cheers.

One X does not support 5GHz wifi. I see only 2.4GHz in official spec

Oups, I thought it could as i can see it

Switch your router to 2.4, and it will work

I thought it was 2.4ghz only cos of the specification too but i can connect to my 5ghz frequency on my Netgear WNDR3700.

I can see and connect to my Netgear 5Ghz WNDR4500 no problem at all.

You guys can tell me what parameters do you use for your 5ghz ?
Thanks.

My router is fairly new, just bought it 2 months ago. I didnt change any of the settings, just plug & play. Even didnt change the router password.

The problem is with Linksys router's wireless .
even in my house we used to have a Linksys router , kept on disconnected when over 3 devices are connected to it , keeps on disconnected every 2-3 minutes really.
changed the router , and everything is smooth now

I have tried to double check this spec on the HTC offical website and it does indicate this phone supports WiFi 5Ghz, as it is with Wi-Fi 802.11 a/b/g/n
htc.com/us/products/htconex-att#tech-specs
however, i have tried to link with a DLink router, DIR-857, and it sees the 2.4Ghz SSID and could connect without any problem, however, not able to see 5Ghz SSID though, i have also tried to set no security and with different channels but seems not have any lucky to this.
i am wondering is there any particular setting to the phone or router double checked with customer service but seem not really help, only ask me to change and try with another AP or router.....

I'm connected to my 802.11a AP with no problems at all. Ditto for 802.11g. I don't have 802.11n here so no idea if that affects it or not.
I didn't need to do anything special on the phone. The AP is a Cisco AP1242AG and it has the usual configuration with WPA2-PSK.

WiFi Keeps Dropping/Disconnecting Through Second Router

First of all, I have internet from Time Warner Cable and it came with a router/modem all in one. Now that was initially set up and that works 100% perfectly with my SGS2. Since I have a weak WiFi signal upstairs in a couple of rooms, I decided to hook up an extra router that is set up as an access point. The second router is connected via a cat5e lan to lan to my main router (home is wired with cat5e connections).
Now on the second router, I have disabled DHCP since the main router is responsible for that. On the second router, I set up a different SSID first to test it out. All wired and wireless connections worked great through my laptop/Xbox 360, PS3. My SGS2 connected fine as well and worked.
Now the issue is that the SGS2 "drops" the WiFi after some time. Sometimes it happens after 5 minutes, sometimes 30 minutes, etc. Even with the SGS2 right next to the router it happens. Meanwhile, my laptop stays connected the whole time.
I can't seem to figure out what the issue is now. I've reset the second router a couple times and set it up all over fresh but it doesn't fix the problem. Seems to be a problem with my brother's Sensation as well. Is there something with Android and access points or going through a second router that causes issues? Any other settings I'm overlooking? SGS2 connected to the main router stays connected until I turn WiFi off. But to the access point, it drops out after some time.
FYI: Second router (access point) is running DD-WRT firmware.
If you need any other info, just ask. I'll be home from work in a couple hours. I've been messing with this for the last 2 weeks but nothing seems to work. Please help! Thanks.

Hmm thats very odd. Im running a similar setup as you, except my main and 2nd router connect via 5ghtz N.
Have you tried statically your phone with an IP address then modifying your main router (that gives DHCP) to reflect that IP is permanently assigned?
edit: to hard set your phone...settings-->wireless and network-->wifi settings, then menu key and advanced. Just fill in the IP and gateway info, and obviously use something in your DHCP subnet. You'll have to look at your DHCP subnet, but you'll probably use 255.255.255.224 as your mask, and use your gateway (your main router IP) as your DNS.

Try giving your phone a static IP from your main router. Also make sure that you adjust your phones wifi settings under advanced settings so that your phone stays connected to wifi during sleep. Hope that helps.

Well my phone is getting the same IP address each time, whether I connect to the main router's SSID or the second router's SSID. But I will try this static IP. One problem is that I don't know how to find out my DHCP range. There's nothing in the main router's settings about the range. The second router has an option to set the IP address range for DHCP but the main router doesn't. See attached image.
I'll try to set the static IP around what the IP addresses of other devices on the network are since I don't know the exact range. Let me know if I'm doing this wrong. Not sure what you meant by 255.255.255.224 there.

The static IP didn't make a difference. Still keeps disconnecting/dropping after some time. Meanwhile, the connection with the main router stays connected. Don't know what else I can do. Seems that my HP Touchpad running CM9 stays connected to the second router without dropping. Don't know what's different about that from my phone.

Does anybody have some instructions on how to set up the second router as an access point? I'm pretty sure I set it up correctly but apparently there seem to be some issues. People who have a similar setup that can help would be great.
Main router from cable company with built in modem where internet connectivity comes from is downstairs. Connect cat5e from LAN of main router to LAN of second router upstairs. Second router set up as access point for better WiFi coverage upstairs.
2 options for second router: DD-WRT D-Link DIR-615 or D-Link DIR-625.
"Could" buy some other recommended router for this and try that if needed, but would definitely prefer to use what I have and get this to work.

This might be completely off but I had a similar issue with my SII when connecting to 802.1x networks at my University. I downloaded this app called wifi fixer and it resolved the wifi connection drop for about 90% of the time. Give it a shot, it might do wonders for ya.

First you need to find out if your router is supported. According to the DD-WRT database, the 615 is, the 625 is not. But there are several revisions of that router, so you need to find out what revision you have. It should be on your label.
Router database
Then you need to decide whether you want a repeater, an access point, or client bridged. You can read the differences in the DD-WRT wiki found HERE
Then you need to find the best build to flash to your router. I suggest reading the overview of the 615 found HERE. Read the ENTIRE thread. If you flash the wrong version to your router, you WILL brick it.
Then flash the appropriate firmware, set it up, and youre done. Youre going to have to do some reading.
edit: I would also suggest downloading wifi analyzer on your phone and do a site survey of available channels in your house. Most likely you WILL have interference from neighbors. Youre going to want to hard set your channel to the least congested channel, either 1, 6, or 11. Once you get DD-WRT set up on your 615 you can do a site survey within the router as well.

change the channel on your router to 6 not 11 i had that issue with our second router and actually my nook color. Depending on the router it should be under wireless settings.

The only reason to use one over the other is congestion. Thats it. And you want to use 1, 6, or 11 because the DIR615 has N capability, and you need a wifi primary channel to use N. Theres only 3 primary channels...1, 6, and 11.
edit: Heres a technical overview of N: CLICK ME!

I have actually done all that. The DIR-615 is an E1 version and I flashed the correct DD-WRT firmware on it. I followed a tutorial from the DD-WRT website to set it up as an access point as well. My laptop works perfectly with it. Just my phone keeps dropping the connection from it. My main router is on channel 11 and the second router is on channel 6. I also tried channel 1 but it didn't help.
I might just to try set it up as a second router on a different subnet than the first router and see if that helps. Going to try to follow this Youtube video and see how it goes.

Hhmm ok. Well your main router shouldn't have anything to do with it. When it drops does it re-aquire an IP and reconnect? Honestly if a reboot of the router doesn't fix it and your laptop doesn't have the same issue, its pointing to the phone.
Maybe a factory reset?

It reconnects when I unlock the phone. Sometimes I have to reset the Wifi on the phone. Have set the Wifi connection to never sleep. My brother's Sensation was doing this as well. I'll have to test it out on his phone and see. I'll probably reset my phone later today and see if that works.

WiFi with a Repeater.

HI guys, i have set a WiFi repeater in my house but every time i go to the 1st floor o have to turn WiFi off and on to make it connect to the repeater, is that normal?
Thanks in advance.

What kind of repeater is it? Netgear? Belkin?
Have you made the SSID the same as your main network? I found that when I did that, my repeater worked flawlessly with my wireless stuff in the house... didn't believe that that stuff actually worked but it was really good to see.
Works fine on my Nexus devices. It doesn't sound normal that you're having that issue - maybe try a reset on the repeater and your main router just to be sure.

It's a Tp-Link, but the thing is i have to turn Wifi off and on on my GNex to make it connect to the repeater, if i don't, it stays connected to the router downstairs, even with a strong signal from the repeater on the 1st floor.
Is this supposed to happen?

Same Issue
I have the same problem with a Nexus 7 / Android 4.2 and a TP-Link repeater.
Android wont switch from Router to repeater even if signal strength is Router: ~50% / Repeater: ~100%.
Switching Wifi off and on works. But there has to be an other solution.
"Best Wifi" is an app that should do this if I understood right, but it did not work for me.
Has anyone a great idea?
Thx a lot!

You could try checking "avoid poor connections" in wifi advanced settings. That might help in auto switching between the two. I gave up on having the same ssid on my router and repeater. My problem was I was auto switching between the two and during the switch there was no data. So now I use 2 ssids; connect to the router when upstairs, and the repeater downstairs.

Thanks for your help. Android 4.2 does not seem to have that option. In the advanced options I set up static IP adress. There was no checkbox like that to be found.

I'm digging up this old thread because it was found easiest in google search and because I have the same question. It seems more and more we have to switch off wifi and then turn it back on to connect to the repeater. I have the same security and same SSID on both. There has to be a solution to this issue by now. Maybe someone can chime in? An S3, S4, S4 Straight Talk and F7 are all doing it.

Won't connect to any wifi access points

I've just bought a used HTC Desire on eBay. I've tried to connect it to all of the three (!) wireless access points in my house, and it won't connect to any of them. It gets as far as trying to obtain an IP address, but then gives up after a couple of minutes and disconnects.
The routers/access points are:
- Draytek Vigor 2920n
- Buffalo WHR-G54S (running Tomato)
- Belkin Play Max N600 F7D4401
I've tried a factory reset on the phone and it made no difference. It's running stock (as far as I know) Android v2.2.2, and is locked to the Three network.
Can anyone suggest anything?

I already have a spread of channels - the 3 routers are on Channels 4,6 and 10. If the channel were the problem presumably the phone wouldn't see the access point in the first place??

Hi itm,
Can you provide details such as what ROM, Recovery and Radio you are currently using on your HTC Desire? The post is framed around networking so I will be focusing on that. However, it is possible that the issue is with the smartphone. Can other wireless devices on your network connect to the router? Some ROMs may be missing critical drivers or perhaps it simply does not support the configuration you have on your router/wireless access point (WAP).
Also, being able to detect the wireless SSIDs being broadcast does not mean that the problem does not reside with the smartphone. If it cannot perform a handshake with the WAP then the problem could be because the HTC Desire does not support the configuration of the router.
Suggestions from most likely to most unlikely and the decision to change.
1. Human error when inputting passphase
Check your wireless passphrase is correct when inputting it in your smartphone or temporarily set it to a passphrase that you can easily type in to rule this out.
2. Passphrase is too long or uses unsupported characters.
Try using an alphanumeric passphrase and make sure it is only 63 characters or less.
3. Using a supported wireless encryption (router side).
Try setting the wireless authentication algorithm to WPA2, WPA and WEP and unencrypted (last resort).
As you are running the Tomato firmware, only set it to WPA2 and not with TKIP (unsupported in official build).
4. Problems with DHCP settings
Sometimes the smartphone may be unable to obtain an IP address from the DHCP Server, so setting a static IP addresses is a workaround.
Try setting a static IP address by going to the WIFI screen in Settings and long-press on your Wifi SSID (name), select modify and setup a static IP address. It should be within the IP Address subnet on your WAP, e.g. if your wlan0 is broadcasting on 192.168.12.0/255.255.255.255, setting a static IP Address 192.168.12.5 will work, but 192.168.1.5 will fail.
If there is no 'modify' option, press the Menu button and select Advanced. If that option does not exist, select Other Network and manually input your wireless settings.
5. Check the signal strength on your smartphone. A reasonably acceptable range is an RSSI of around 60 for wireless. Are you moving to areas with poor reception or where there is interference? For example, a running microwave or other electronic equipment running within the same wireless frequency will cause problems; 2.4GHz, 5 GHz.
6. If you are using wireless-N, that is 802.11n (full or draft), try using 802.11g or 802.11b instead.
7. Try disabling mobile data and attempt to connect via WIFI again.
8. If all else fails, I would be flashing another ROM. I ran into a similar problem once, and flashing another ROM allowed me to connect to my WAP. Turns out it was an issue with the kernel, though.
On a possibly related note, why not upgrade to Gingerbread? It has better power management and there is an official release by HTC if you are wary of developer ROMs.
