Obtaining IP Address issue

I have searched for this issue and there are TONNES of threads about it and a lot of proposed solutions but none of them work for me. I have been using this HTC Incredible for some three months now and have gone through various ROM's including some Sense based, CM7, a couple ICS ROM's and MIUI. But every one of them gives me this problem with the wifi at work. The phones finds the network, connects to it, authenticates and then gets stuck at Obtaining IP Address... and then repeats the cycle.
I used to have an iPhone that worked well with the same wifi spot. My friend's Nexus running ICS connects just fine. But my phone exhibits this problem with this wifi spot and a bunch other public spots it has connected to before.
From reading various threads, it happens when Android remembers the last IP address it got at this spot and tries to assign itself that but fails. It does not learn to ask for a new one. Which is verified by the fact that assigning a static IP, then going back to dynamic IP address makes it refresh the IP request and work for a little bit. Then it goes to sleep and the same agonizing cycle starts again.
Is it because of the hardware? Is it because of the Kernel? Does anyone have a clue?
I have tried Wifi Fixer app and that didn't help. Another person has listed three other apps and how those did not work for him (so I didn't even try them).
At this point, this issue is so frustrating for me. Can anyone recommend some more ideas for me to try? Different ROM's, different kernels? Anyone? ANY one?

This happens to me intermittently when I come home. Multiple ROMs and kernels, no rhyme or reason. When I notice it, I restart the phone and have to turn WiFi back on. Then it works fine for a day or longer. I wonder if it's a bug that's triggered by background processes.

I came across this possible fix while searching for something else. Wifi Won't Connect
Also, I would not be so quick to write off those other apps you mentioned, it is very possible that the person who said they did not work had something different that was causing the Wifi to not connect/obtain IP.

Thanks guys. I have installed a new Kernel and will try it as well as the above suggestions in the next couple of days and report back. Here are the suggestions made so far:
1. Turn wifi off. Restart the phone and turn wifi on.
2. wpa_supplicant renaming
3. Other wifi fixing apps.

Have you tried forgeting the network in the wifi settings menu and then try connecting again?

Yes, I have tried forgetting and starting from scratch again. And with the new Kernel, it just doesn't connect at all. Gets stuck in the Getting IP address loop even for the very first time. I tried #1 but that didn't do anything. I cannot rename the wpa_supplicant because I don't have the USB cable with me and the ROM doesn't let me access the internal storage in ES Explorer. And since I can't get on the wifi, I can't try the other wifi fixing apps (#3).

[Q] Push notifications delayed on WIFI

I've seen a few similar threads to the one I'm about to make. I've tried different suggestions which I will post here. Yet, none of them seems to work and I'm curious to see if anyone of you has a fix for my problem. My phone is an unbranded international HOX using the 9.7.2 ARHD rom by Mike1986. Here we go:
Problem
While being on WIFI my push notifications aren't coming through in time. There's a delay from anywhere between a few minutes up to as much as 40+ minutes. The phone doesn't have this issue being on the mobile data network. I'm also not 100% sure if the delay is still there when I'm on an different router. Even when I turn on the screen again, the messages seem to come in randomly.
Settings
WIFI best performance enabled
Static IP by router
WIFI sleep policy: Wifi always on
Tried suggestions
Wakelock: One thread described using an app called REGPON keep-alive, which installs a wakelock onto the phone to keep the data connection alive. This app did not do the trick. It only drained my battery and the messages still didn't come through.
Wifi performance: Set the phone to maximum wifi performance. This seemed to work for a while but ended up not working proper either
Kernel: Try a different kernel was one suggestion. I've switched from Stock to Faux123 010 kernel. This didn't change anything about the WIFI problem.
Static IP + Portforwarding + Disabling router Firewall: I've tried both port forwarding on port 5228 and even the range 5224-5228. I've also tried setting up triggered ranges. Maybe I'm doing something wrong on this part though. The router firewall is disabled and it should no longer block anonymous WAN packages.
Disable SmartSync: With the Suite Tools that are included in Mike1986's rom I've disabled Smartsync. No results as far as the wifi problem goes.
Probing app: I've tried an app that supposedly probes my router at least every minute in order to keep the connection alive.
Switching between b/g/n network: Didn't make a difference. The signal quality of the router is also good.
The only thing that did work for extended periods of time was using this remote control app that allows me to type through my PC keyboard, where the text ended up on the phone. I've also got an app installed to test push notifications. It's capable of making a log. Maybe that'll give you guys more information.
Right now I'm not sure if it's an issue with the HOX or if my router somehow stops the traffic. I don't recall having this problem on my HTC Desire. Does anyone have anymore tips?
Thanks,
Zendio

No problem with Gmail push notification on Stock 2.17.401.2.
Yesterday I still was on ARHD 9.7.2, also there I never noticed any delay.
Edit: this complies to various wifi networks (@home, @office, @parents etc.)

I am so sorry to hear you are affected by this problem, but also happy someone else is experiencing the exact same thing as I am !!!
I have tried different solutions to no avail.
Would love to hear something on this topic !!

Also I should note, I don't have any kind of task killer installed.
In general use WIFI feels really fluid and responsive. I really have no idea what could cause these problems.

I hope so. My One S is experiencing the same thing. I've tried everything above. No luck. Some stuff is fairly critical that I get it as soon as it comes in. I might try getting ahold of a Nexus 4 and do some testing with its wifi, just to make sure it isn't a general Android problem.

What router do you have? My issue was any android device in the house. Turned out it was my router, I put a custom firmware on it and all my trouble have gone away. My friend has the WiFi issue on a virgin media superhub.

I have an Asus RT-N66U. Funny you should suggest that. I'd planned to throw Tomato on it tonight and see how that works out. I did some tests at my folks' and their router had the same results. It's some cheap Netgear thing. Not sure of the model at the mo. I'll post back with results. If not tonight, tomorrow some time.

No go
Well that was unsuccessful. Actually it slowed things down. With the default firmware I get notifications from the instant I press power to wake up my phone. With Tomato there was a second or so before I got them.
Time to try DD-WRT tonight to see if that does the same thing.

I have an rt-n56u so the older version of yours and I'm running the Asus wrt that is being made, its fixed all my problems and is awesome tbh.

Set Beacon mode power safe (BMPS) to 0 in WiFi ???.ini config file should resolve this problem.
Such ???.ini config file usually placed under /system/etc/wifi or /system/etc/firmware/wlan/prima/

Wi-Fi unreliable

Recently I've been having problems with Wi-Fi. My phone and nexus 7. They both stay on blue bars all the time claiming they're connected to Google servers. And it'll work good for about 20 seconds and then I'll have no connection for about a minute. Bars will stay blue like its connected and WiFi show that it's fill signal but pages won't load, apps will timeout and YouTube videos won't stream. Makes it impossible to download any Roms or apps at times. This just recently started happening. Videos will stream good for maybe 2 minutes tops. Then pause, after a minute Wi-Fi will stay streaming and going again by itself and stream. I haven't changed my router or is settings. I have static ip's assigned too. All other computers work just fine for internet. Never a problem.
I've tried changing kernels, Roms, complete wipes and reinstalls. Rebooted the router. Nothing fixes it. I'm getting really frustrated. I'm at the point where I'm going trio go buy a new router just cause I want to use 5ghz. Anyways, any suggestions to solve this?

There may be an error in aosp code that can cause wifi instability: http://forum.xda-developers.com/showpost.php?p=35146886&postcount=5128

Weird how it affects just my device in an entire thread with a ton of people using the rom and same kernel.
I went and picked up a new router. I'll see if that fixes it. Thanks for the input though. I appreciate it.

Didn't help with new router. My WiFi still cutting out like crazy on Franco kernel. Almost as soon as I turn off screen. But its not turning WiFi off. Just goes into some sort of state where nothing comes through. When screen on everything is fine though now.

In Wifi settings, you could try unchecking "Avoid Poor Connections" and see if that helps.
Also do you have any other devices at home on the same wifi network - do they experience the same issues, I know where I am if we get a lot of rain, it causes intermittent internet slowdowns, I had similar issues and after testing other devices found this to be my problem not my Wifi.
Also, have you got any cordless phones in the house that might run on the same frequency?
I still have an issue keeping wifi at 100% d/l when the phone is asleep, even though the setting is for always on. It must be a hardware thing for me because every rom I've tried from ICS to the latest JB exhibit the same issue. If I am in a desperate need to d/l a large file on my phone, I just temporarily change the screen display off timer to 10 minutes of so so the wifi will stay at max d/l speed.

Ya avoid poor connections is unchecked. And wifi optimization is unchecked. I've tried putting my router on full auto, tried setting static ip addresses for everything. Changing from wireless n to wireless g. Changing security to off as well. Using the 5ghz band instead of 2.4. The nexus 7 is working perfectly fine with the new router. But my galaxy nexus is totally unreliable. Weird is that it just started happening within past couple weeks. And actually, it was good for the first day or so after new router. I can confirm all other wifi devices jn the house work just fine without any hiccups. I've never had a problem with other devices. No dropouts or anything. It's really puzzling me!
One thing I found weird, if I disable wmm on my router, my nexus 7 and galaxy nexus will not connect. Anyone else get this?

I hope you also have your router firmware completely up to date.

Ya my router auto updates itself. Its a Cisco EA6500 in case your wondering and is helpful.

I use my wifi at work and it's very unreliable. At times going into an endless disconnect/reconnect loop. Sometimes restarting the wifi helps or putting it in and out of airplane mode. Other times nothing helps except a reboot of my phone. Some apps may make the issue worse. I don't think there is a fix and waiting for google to fix the flaw a user pointed out earlier.

Possibly a 4.2 issue. But its not affecting everyone it seems. But i see that there is a huge thread about this at the google site. Not an isolated case

When you say you set a static ip, you set one from the router, have you tried setting a static ip on the phones wifi advanced options as well?
Have you tried different radios?

Yup has happened to me mine connects to the net but has grey bars and doesn't open any websites and apps dont connect to the net a reboot solves the problem

I set static on both router and the phone. I've tried all the north american radios. None of the euro ones. no effect. Sticking to the latest North American radio for now. I've managed to make it work sorta with CM10.1 with stock kernel on completely fresh install. It works, but the down arrow on the Wi-Fi icon stays lit almost 100% of the time. no idea why, only other device that was on all yesterday was the nexus 7, and that was on the 2.4ghz and phone the 5ghz. Huge wlan_rx_wake!

It's likely this:

See if that sounds about right and if so, you'll just have to wait for a Google Patch.

When i first updated to 4.2, I was getting crazy dropouts. After unchecking the Wi-fi optimization, it was more consistent but still drops out frequently while at work. There is a known bug with the wifi driver that hasn't been addressed for years, but still trying to find the original articles describing the problems.
It seems you are having tons of issues, worse than most.
If you are having a problems suggested on this site, maybe this can help.

It affects me as well. Completely random. Everything appears fine except that instead of blue, the icons are grey. Turning off wifi and turning it back on fixes it.
In the link above, there is a comment where you can submit more info for Google to help solving the problem:

the weird thing is, it just started happening about 2 weeks ago. It was perfectly fine up until then. Never had an issue with Wi-Fi. If this don't work i might try doing an entire wipe right back to stock and locking bootloader.

Sightly strange WIFI issue

Good afternoon XDA HOX owners,
I'm having a really strange problem with getting on to my wifi AT HOME ONLY.
The phone sees the wifi, registers the strength of the signal, but loses connection all the time. it's the first time I've had this issue with a gadget, and this is the 4th smart phone that's been owned in my household, while using this particular wireless router. there's also 2 laptops, a NAS and an iPad (EEWwwww ) ... and my mates that have my wifi password get on without an issue...
If I turn the wifi on the phone off and on, it works for maybe ten seconds to a minute, and then drops connectivity, but not the signal. I know this because of the little 'up and down' connectivity arrows that run in the CM10 wifi indicator. they go either up, or down or nothing, but the signal is still there.
Any help would be massively appreciated as it's ruining my love for the awesome device the HOX is, especially running CM10.
Thanks :good:
your auntie mable

Gonna bump this thread up because I'm home and it's driving me batty!

I had this issue with my homehub on the 'n' setting. Something just didnt work between the phone and hub. Try changing it to 'g' if its not that im at a loss. My.x would work everywhere else but home properly
Now works flawlessly
My nexus used to fly with the hub. Slightly irritated i had to lower performance purely for my phone. Its npt a massive difference but theres a reason theres a g and a n lol

I'm having similar issues with my Wi-fi at home, tho my connection lasts longer, sometimes 10 mins, sometimes 5 hours+ sometimes all day. The strange part is that when i use wi-fi on the phone alot like some sort of heavy stuff youtube, downloading etc. then my connection drops. I've tried using only N connection and BGN Mixed on 20 and 40HZ channel and N seams to give me the best results, never tried B and G connections since i think those reduce the range of your WI-FI , too bad i didn't go for A B G N router. Anyway could be up to my router or something, every device that uses my WI-FI has same issues with this router. I even took it to the repair center they've done some ping tests and showen me that router works perfect. anyway back home still does those buggy things. If anyone has any good idea please feel free to suggest us.

I'm also having an issue with mine, although slightly different.
My phone connects to available wireless with no problem and stays connected however when I leave that location it stays connected instead of switching back to mobile data. I have to turn off wireless and then turn it back on to get it to switch to mobile data.
Kinda a pain in the arse and really annoying. I've missed allot of important emails since I got this phone due to me forgetting to turn wifi off everytime I leave somewhere with wifi.
None of my previous smart phones had this issue. I'm hoping that if I get custom rom on it, it will work properly,

Sudden WiFi problem.

Please help.
Suddenly I have weird WiFi problem where, for instance, it won't even connect to my home WiFi. Sometimes it is saying 'Saved' sometimes 'Obtaining IP address' and sometimes 'Connecting'. When I finally get connection, sometimes it just disconnects for no reason (well, there have to be a reason), and again wouldn't connect. For instance, while I am writing this it is Obtaining IP address the whole time.
I couldn't find the pattern in these problems, but someone might be able to help.
Tried resetting modem, phone, clear cashe...
I didn't notice that my MacBook have any issues, nor my LG TV. It works fine there. I'm on 7.1.2.
Hope someone can help.

Have no idea if it is related, but found somewhere online that I might have bad app. Went back and checked what apps I have installed recently, and those were two apps for my new UHD LG TV. Uninstalled them, and problem went away.

The 5X's wifi sucks. I travel with my Note 4 also since that always connects to available networks, like at hotels or at airports. The 5X will often just do what yours did. I have access to Time Warner hotspots since I have their internet service. But it almost never connects and when it does it usually takes many attempts. My Note 4 would connect so easily that it would connect when I was stopped at red lights or even stop signs. The 5X takes lots of messing around. Adding and forgetting the network. Turning wifi off and back on, etc.
I have the Time Warner app to assist in connecting and that helps. I thought that app interfered with the wifi, so I remove it when travelling, but found it makes no difference.
I did find that Skype Wifi, which allows someone to connect to hotspots around the world and pay using Skype credit, did interfere with the wifi like your apps did. So some hotpots would work without it installed, but wouldn't with it installed. I took it off, but of course I can have in on my Note 4 and have no problems with any wifi hotpots.

I would agree that the 5X wifi sucks. I have issues on my home wifi as well & know it's not the network. My older Nexus 5 connects & stays connected fine. and the 5X will be setting right next to it & be 'obtaining IP" or say "No Internet" -- anyone have any other suggestions would be greatly appreciated. Enjoying the phone - but not this issue.

I've been having wifi problems since I got mine months ago, my internet connects for 0.5 of a second then disconnects even if I stand beside my router

I had forgotten about an issue with my router, but it affected the router. The 5Gz signal would just disappear after about a day, which would require rebooting the router to restore. I went on vacation and the router made it 3 weeks without needing to be rebooted. So obviously it was the 5X causing the issue. The router manufacturer was going to RMA it, but one of their engineers sent me a beta version of the firmware that ended up fixing the issue, but I can not use any official firmware release. My 5X now, if I put it on the 5Gz signal, will just stay for a while, then I'll look at the phone and it'll have switched to the 2.4Gz signal. So I just let it stay on that. At least the router signal doesn't completely disappear anymore, but the core issue with the 5X is still there.
One of the steps in trying to fix wifi problems used to be setting it to 2.4Gz networks only. 7.0 or some version of the OS took away that option. Someone in the Google forums requested it be put back in, but it doesn't look that that will happen.

It's the phones connectivity it's messed up, and u are able to get it replaced if u got warrienty

I did a factory reset and it does not resolve the issue as I have been having issues for the past month or two. i think its one of the updates that borked it up; but until i roll back idk

If anyone can make your 2.4 band a G type or mixed mode router and leave your ac band alone. I noticed that leaving the connection to G type keeps the connection solid for me and drops go away. I know this is not a solution but until this can be resolved. This didnt happen before and for the like of me it is IMPOSSIBLE to flash older firmware and system images on the POS device. It get stuck on the Google logo.
There was a post awhile ago in a different phone thread for HTC ( yes, i know its not the same ) but there apparently appears to be WiFi 'drivers' or 'radios' if you will and the solution was easy there, but here I think someone with some experience might have to point those out to us. ( its on this page https://forum.xda-developers.com/ve...tock-m-firmware-nand-recovery-t3330972/page32 )
I am wondering if using a set of WiFi drivers from 7.1.1 would resolve this issue or not, but I am unsure where to go to find them; anyone?
