[FROYO WIFI FIX] 2.2 Wifi stuck at "Obtaining IP Adress"

A real fix has been found for this issue please follow this link to learn more
http://forum.xda-developers.com/showthread.php?t=907772

Awesome, thank you for this. I was having similar problems with mine after the Froyo flash too. I'll give it a shot.

I've been using Froyo since DG posted the link to JI6...and I've never had this issue. I use wifi on a daily basis. Weird.

Super weird...what would your android id have to do with wifi?
Oh and this belongs in general!

I didn't have any issues until Cog 2.5.5. Once I flashed it my wifi just quit on me. I tried going back to stock Froyo to see if that was the problem, but no luck. As soon as I changed my device ID to what I had on Eclair everything got fixed.

I was having the same problem. I found a workaround that doesn't require changing anything on your phone. I accessed my router settings, changed the security type from WEP to WPA2 and the phone obtained the IP address immediately. Hopefully this will help out those of you who aren't familiar or comfortable with flashing your device yet.

Thanks for the info. Decent work around. I would still like to resolve the issue, but for now this works.
I did all of the steps in the original post, but it did not correct the issue. Actually made my phone worse. Now I cannot get into download mode, and I'm on Cognition beta 8 and my GPS does not work. It was working on Froyo leak, but had these same wifi issues.

This workaround is not working on my fios router. It is working on my netgear router at work. I'm not that well-versed to explain either situation. I just don't like hitting my data plan when I was getting wifi before 2.2 flash. And even then, it was working for a few weeks.

I ve flashed my phone and everythjng works great till one day when I wasn't able to connect to my wi fi at home (using wep key). But at my office works like a charm with wpa key.

If you are still having issues with your wifi after using the two work arounds mentioned in this thread I would reccomend flashing back to stock JF6, doing a master clear and reflash your current ROM. I would not suggest restoring system data using TiBU after doing the master clear as this could carry over your wifi issues. Yes I know it sucks to have to redo all your settings, but if it gets your wifi working then I would say it's worth it. After you restore your apps and such reapply the first fix that I mentioned to change your device ID back.

I did all the steps you mentioned in the first post. But I dont see any Android_id entry in secure tab.
I am using sqlitebrowser to edit settings.db file.
I am getting wi-fi getting Ip address error after installing odin3 1 click froyo update for captivate.
any other alternatives?

Has anyone tried assigning a fixed ip address, this worked for me.

Some people have had success addressing this issue utilizing the app Wifi Static".

For me, it was due to some zombie ap that I did forget. Ever since, my froyo got back to normal. The ap is svuwired.
Sent from my SAMSUNG-SGH-I897 using XDA App

Don't see why you have to do all that. Just flash back to stock and wifi works again.

I'm using a stock Froyo (official release , rooted)
when connecting to a Linksys N150 router, Im stuck at 'obtaning IP Address'
it's the same whether there is no password, WEP, WPA
on a linksys WRT54GH I can connect without problems, but oftentimes even if the phone shows that I'm connected via Wifi, there is no data coming through. I will need to disconnect and reconnect to my router
on both setups, I am able to connect and surf using my ipod touch (4th gen, on ios 4.1)
this is especially frustrating for me because there are 3 Galaxy S users in the house (the other two are my sisters, who bought the phone because of me)
HEEEELLLP

hey guys, i have the same problem and tried to fix it by editing the device id .. but my device id is same as from what i have noted down... plzz help me guys

WIFI problem after ICS upgrade

HI. Today I updated my non-rooted HTC Desire S to ICS 4.0.4 (3.0.16-gce03037 Kernel) from official site... Everything is working fine, but I have problem using the WIFI connection.
I can enable/disable WiFi, I have no problems with OS freezing when I switch on or off wireless, etc. I configured it properly (I did not restore any settings from my backup software) and manually, and in status bar I can see that network is connected. It seems that everything is working fine but:
1. I cannot access the Internet from the phone
2. My access point does not list my HTC as connected device at all
I am desperate because this is the only thing that is not working after upgrade, and I use WiFi a lot
Thank you all for helping regarding this.

I don't know if it is the same issue i was experiencing some time ago, but seems that older Wi-Fi router have some problems with ics roms and later versions (jelly bean). I have resolved by changing my router but you could try specificy a static ip address for your phone and see if it works.
Sent from my HTC Desire S using xda app-developers app

I already have a static IP defined. Also my WiFi is protected with AES. Is there any way to keep ICS on HTC and to degrade only driver for the WiFi?

No, I don't think so, but maybe the AES encryption could be the problem. Try swiching to WPA or WPA2 and see if it works.

Well, no. You could still try to root your phone, install a Jelly Bean based Rom and specify a static IP. JB is slightly better with WiFi than ICS so I think this is your last call.
Otherwise you can still use the pass-through internet option is "Stock option" of the Rom settings, but this means that the phone must be plugged in the PC.

Is there any 3rd party software which can manage WiFi chip? Something like option in MS Windows, where you can choose Windows to manage wireless or vendor application. Maybe it is not a firmware problem, maybe it is something with ICS subsystem/application which handles WiFi...

Not from my knowledge. You can try downloading wifix from the market, for some users has worked, but not for me.

OK, now things are getting very weird!
First of all, I tried with "wifix" and bunch of other market "wifi fix apps", but with no success. After that I connected to my WiFi and try to ping my laptop which resides on the same AP and.... with SUCCESS! I looked at my AP statistics and I cannot still observe that my HTC is connected to the AP, but I could ping the laptop and default gateway (which is AP of course). I tried to do SSH to the HTC and that was successful too. It seems that my WIFI is working only locally, because when I try to ping public IP I get the destination unreachable error message. On the ifconfig's interface statistics I can see Rx and Tx counters increases on the wlan0 interface, but on the AP I still cannot see that my HTC is connected.
I looked up in to the routing table, and there was everything as should be. I am sure that there is no IP address conflict inside my network, I am sure that my HTC is authenticated and connected on the right wireless channel.
Guys, this issue is very weird, can somebody give some hint about it?
Please, see attachments there is much more info regarding this.

equally eelsec
Ok, here is the update in attachment, it seems that I have problem on the layer 3 of the OSI model. I think that I can summarize the following:
1. Radio is working
2. All MAC layer things are also fine
3. Encryption is ok
4. IP packets transportation between the HTC and router is not working.
I am not good with linux, and my phone is not rooted.What can I do to troubleshoot this part of the networking now?

Hello to all again.
Believe or not I still have the same problem. HTC support is USELESS... I tried with factory reset, and I still got a problem. I am loosing patience now... Can somebody tell me how to revert back to previous OS, please? Where to download, and how to install it?

TF300T Tethering Hell: USB, WiFi, Take your pick...

Hey guys If I am in the wrong place, please let me know. I got my TF300T just a little while ago and am now trying to use it as a my main computer. That requires me to able to connect to the net on it. It works just fine when I am connected to a regular WiFi network. However, I have no Internet connection at home except for my Sprint Motorola Photon Q, which I had been using tethered over USB to my PC to get the PC online. That worked fine. But this past month, I lost my job and needed to sell the PC, so all I have left is the TF300T. I was sure it'd work fine since I got BT tethering to work fine in the past with that phone. However, I was just experimenting at that point. Now, I see it's a little more ... complicated:
I set my Photon Q to act as a WiFi hotspot using PDANet+ a.k.a. FoxFi. Creating a WiFi hotspot, I can see it on the TF300T. Whether I enter the right PSK2 key or don't use encryption at all, connecting is impossible. It will "Authenticate...." after a minute or so and then try to get an IP via DHCP. Then it will "work" a long time and then drop the connection and try again. This is with the phone an inch away. I found it had a lot of trouble just getting an IP, so I tried setting it up with a static IP. I found out that PDAnet+ seems to default to 192.168.43.111 and the gateway is presumably 192.168.43.1. I tried some other things like .100 without luck. It WILL connect but the WiFi strength indicator in the bar stays gray. It shows up and down arrows as though there's activity, and Excellent strength, but won't actually work in any apps, incl. the default Android browser. Also tried pinging the host phone using the terminal only to get Destination Host Unreachable errors.
I then tried Bluetooth tethering. It will connect and works at a decent rate. But, the only programs that work are web browsers! IM clients, Skype, Google Play, Maps, Gmail, nothing else can connect. Android is convinced I am not online at all, yet I can browse web pages at full speed, which I am doing right now. IIRC PdaNet uses some bizarro proxy setup but they tell you on their site to "configure the proxy settings" and give you none of the details like IP or port! How useful. So, this does me little good. It's horribly crippled.
I tried numerous other WiFi tether apps, most of which hard crash the Photon Q so it reboots entirely the moment it turns on the hotspot. Barnacle and one of the WiFi tether apps (1-click? I've tried so many I can barely remember...) will launch, I can see it on the TF300T, but when I try to connect it says "ANDROIDTETHER or whatever the SSID is, Saved". No matter how many times you choose Connect or Forget, then Connect again, nothing. Gets stuck at "Saved."
I'd try connecting the phone via USB via the TF300T dock but I have searched heavily and cannot find any way to do it. Do I have any options at all?
Thank you for any info.

Hi
I'm tethering Internet from my SGS 1 with 4.2.2 rom with no problem at all. I think you have problem with wifi settings.
Try to set both phone and tab wifi to correct region. If you have phone set to USA and tab to Europe it won't work. You'll find it under Wireless-advanced if you have customised roms, for stock I don't know how to set it. Haven't have stock roms for ages.
About proxy, basic proxy settings in Android works only for browser, so you will need something like proxydroid on your client. I'm using it and for me it is working. For settings, check your phone settings-mobile networks-access points and copy them from there, or call your ISP and ask them for settings.
Hope this helps.

WiFi tether for root users. Is the best thing ever. If you aren't rooted. Root your phone. Also, is there a cm ROM available for your phone? If so, switch. Then use it's default tethering. Your phone is definitely the culprit here.

Unfortunately no CM ROM exists for that phone. It is rooted. I tried wifi tether for root-- played with all the settings.... it will turn on and the SSID shows up on the TF300T .. but if you try to connect it just says "Saved." Even though it also says Signal quality is "Excellent"...
I don't get it at all.

Try different profiles. I tried my EVO LTE last night for 2 hrs. Tried all generic settings. I ended up switching it to sg3 profile same chipset as mine. Worked fine after that.

Yep exactly what kaos said. I had that issue with my HD2 doing exactly what you said. Would "save" but never connect. I ended up using something like the nexus profile or something.

Great suggestions guys! I seem to be making some progress. I can now "connect" and get an IP, but the "wifi signal" bar thingy in the lower-right stays gray, not blue like it usually is when on working WiFi, and apps still cannot get to the net, which I assume is what the gray means (network connection but no internet connection). I will have to go down the list and try every possible configuation, I suppose. Yikes! I'll keep at it...
Thank you!

Certain Websites work on 3g but not on wifi?

Hi All,
I am new to these forums and to android, but have searched this fault no end, and have still not been able to solve this fault. So am looking for some help and advice.
I have a Samsung Galaxy S4 sim free on uk 3 network and started to notice that a lot of links I was clicking from twitter etc were not loading, or I would just get a page not found message like the ones you get when there is a genuine incorrect link posted, an example of this was links from Forbes website.
I then noticed though, if I switch wifi off and it connects to cellular data the same links work first time?
The strange this is on wifi, all my apps etc update fine, and even if I open up samsung browser and go to lots of sites, they all work, it is just a few that dont.
One I definitely know that doesnt work is newsnow co uk whenever I am on wifi and try to connect it says page cannot be displayed, but works on 3g
Some sites I have read say it is linked to proxy settings?
Any assistance will be greatly appreciated.

Sounds like your wifi dns settings. Could be your device, router, or isp. If you can connect to those sites using a laptop or computer on the same wifi then it is the device settings. You might want to check out setDNS in the Play Store.

Yeah I can access using my wifes phone and laptops etc
I will look into DNS setting on S4
Thanks
Is setDNS for rooted phones? Mine is not rooted

I have the same issue. And I don't think is a problem with router or modem. Definitely a phones problem. It happens at home and at my work.
And it's temporary. If you disable wifi and turn it on again it works.

I went to the snapchat support page and went to report new problem under the "cant send snaps or stories" section but at first i couldn't log in to report the problem with snapchat because of course they blocked my ip so your gonna have to go to the link with your phone with your data off or with someone elses wifi. Your then going to want to report what your problem is to their developers and in less then like 5 hours it was working again. I hope this helped cause it worked for me.
Also i got rid of beta cause i think thats a bug in it that it blocks your ip cause of "suspicious" activity.:good:

Hello to anyone still maybe struggling with this. I personally had this problem and tried to entire messaging them about it - to no avail. That being said I believe I've figured it out. I always felt it was my wifi seeing as mcdonalds wifi worked just fine. Hence I finally went into my wifi settings (super convoluted with different extenders and dmzs and ports forwarded to pacify all house occupants) and on a hunch changed my dns settings at the modem level to googles from opendns-2 which was my primary. I left my secondary and tert alone (level 3-r1 and qwest-2 US respectively). Instant results. the only reason I had changed my dns to that in the first place was because a program had analyzed my connection to find what was supposedly the fastest. And while I feel it probably was, the primary was for some reason screwing with snapchat/ig and sometimes fb. anyways I hope this ends up helping someone somewhere out there.

So just to make sure you went in to your routers settings and changed the dns from what it was originally to google's DNS? Sorry for not understanding I'm just trying to recreate what you did to see if it could fix the same problem I'm having. Also if you have any advice on how to change the DNS in the router settings I can't find them for mine. Thank you!!

Hi! I'm having the exact same problem with snap chat and sending my snaps to others over the wifi here at home-- I called Telstra and they suggested contacting Snapchat- hav done that twice so far- selecting my issues etc then entering my username, phone type, email address and number then messaged them the details of my problem.. no response thus far from snap chat.. it works fine when u switch over to to 3 or 4G but no good over wifi.. wtf.. its so annoying!! Have plenty of data to use on wifi but Snapchat app just won't co operate.. I don't know what to do.. I need to know the exact steps to take to try fix it.. is there a way? I see Simone here has managed to do it changing to google DNS but I kinda need step by step help to get it right.. Thankyou in advance to anyone who can help me- and others too it seems who are having the same problem..
hope to get some help with this.. it's sooo frustrating!!

I'm having the same issue. I use talktalk as my isp. They are terrible anyway regarding speeds but i noticed that i couldn't refresh/use snapchat whilst on my home WiFi. I've checked my dns settings and it looks like my dns servers are already with googles free ones 8.8.8.8 and 8.8.4.4...
Anyone know how to fix this issue?!!
