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.

Yeah. Just don't understand how so few here experience this. And only my phone, not my nexus 7 gets this.

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.

Poor wifi performance

For the last month or so wifi hasn't been working well on my phone. I can connect to all of my hotspots and get decent indicated signal strength, but games and streaming are constantly losing connection. This is on 3 different networks and all 3 work fine on my tablet, so the problem has to be the phone. And I've done a factory reset so it doesn't seem to be a software issue.
So.. is there anything physical/mechanical I can try? Or something else I'm missing? Thanks in advance.

Is your firmware up to date, or at least on par with the ROM you are using?

Yes, I'm using SkyDragon 1.0 and the first option kernel that came with it. I just upgraded to it a couple days ago from OEM 4.4.2 and I was having the same issues.

Is there a different kernel I could/should try? Thanks!

Nexus 5x wifi issues

Stock 6.0.1 mtc19v, on T-Mobile, july security update, never rooted this handset
I decided to start my own thread because I didn't want to hijack another's.
So here's the problem. Had my 5x for 3 days. And I love it, but it has weird wifi issues. I can't watch YouTube while I'm on wifi but it starts up with no issues while on LTE. Downloading apps and their updates take up to 20 minutes. While it's instant on LTE. Wifi calling is super choppy too. And my 5x occasionally disconnects too.
Everything else works fine on wifi. Chrome is quick, so is feedly.
So I searched here and on Google and many people have the same issue. Some say 6.0.1 was bugged.
Either way I tried all the advice given to others. My router and modem are up do date. I reset them various times. The problem can be replicated on my sister's wifi and my dad's.
Check my phone's APN. Changed to 2.4 and 5ghz bands on the phone. Went back to auto wifi band. Nothing.
Tried safe mode. No dice.
I even wiped. No luck either.
I also tried wiping the data and cache on a few apps, play store being one of them. Can't remember the other two.
Anything else I'm missing or is 6.0.1 really bugged?
Is there a possibility mtc19z has a fix? I haven't received that update yet.

Forgot to mention
I called Nexus tech support. They say it's not a known issue. Project fi's tech support said the same thing.

Try with bluetooth turned on, doesn't need to be connected to anything.
Also try enabling developer options enable the setting to use lollipop dhcp client.

OK I'll give it a shot

OK so far, Bluetooth on does nothing for me. Apps still download slow and wifi calling does nothing.
I'll try the lollipop dhcp tomorrow, with Bluetooth on and off. I'll report then.
Thanks for your advice.

Hi man, the lollipop dhcp didn't work. Tried it with Bluetooth on and off

Last option I can think off.
settings/backup & reset/network settings reset.
After that I would try doing a clean flash with the latest stock image, no apps etc and see what happens.
If that doesn't work I would return it for a new one.

Tried that too. I'm stock never rooted. I've wiped twice already. Nexus support is barely any help. But yeah I'll try for a swap. Thanks.

Well project Fi couldn't help since I don't have their services. LG keeps telling me to call Nexus. Nexus keeps transferring me to project Fi.
I'm just gonna go buy another phone. This hassle isn't worth it.

You should be able to get a new one under warranty from where you brought it.

My N5X has not had any wifi issues, thankfully, but I have had weird wifi issues on other android phones in the past. What has worked for me was to go into my router's settings and use DHCP Reservation to assign a specific IP address to the phone, and to make sure there were no conflicts in the IP assignments of various devices on the network. I also replaced the router's default DNS servers with Google's.
Those two steps have solved my android-related wifi issues in the past. But, again, I haven't had any issues with the N5X so this may or may not help you.

Nexus 5x wifi + Bluetooth.
So couple of years i use it without bluetooth turned on. With some wifi access points phone can't get in deep sleep. Some other access points sending packets to phone.
One day a read about bluetooth "on" options. And surprise, now phone can go deep sleep and dose not have battery drain.
Now i have to keep my bluetooth always on. Was same for android 6,7,8,8.1. with factory reseted.. different kernels dos not help.
Maybe some heard - it is hardware issue? Its go under warranty?

Google pixel wifi issues

So i have noticed that while i am on wifi for example the videos on instagram take a while to load, this is kind of crazy because i am on fios 5G internet on wifi. Im coming from iphone so i know there was an option on iPhones that chose to give more prescedence that if you were connected to wifi it used the internet from that then the provided one from T-mobile for example. So my questions is, has this happened to anyone else? Or is there any other solution to this?

I've been experiencing the same issue since the time I purchased the device and I'm yet to come across any particular solution. A workaround that I've found is disconnecting the wifii, reconnecting it and then rebooting the device. It starts to work normally after doing those 3 things for at least a day.

I had the problem too. My router was having issues with ipv6 firewalls and only the 5ghz had issues. I solved mine by downloading a VPN app. I'm using NoRoot Firewall and everything works fine now.

FWIW: #9 can't work. There's no option in stock recovery to wipe cache partition.

Wow this is ridiculous man for paying about $1,100 for this phone, these issues shouldnt even be there to begin with.

Try disabling wifi scanning?

where do you find that? but even if so im connected to wifi already why would the phone be searching for additional access points?

Settings -> location -> scanning (three dots on the top right).
I think it scans for other wifi in the area to help pinpoint your location (not sure how google does it).

WiFi disconnect

So, I noticed my pixel 3 xl WiFi is disconnecting frequently.
It's connected to a secure 5Ghz band.
I did reset network, updated to November update
My other devices are properly connected and never had an issue. My S8 has never had this issue.
I did forget WiFi and tried again. It's only pixel 3 xl that's doing that.
I am not rooted and bootloader is locked..

Nope, no VPN either.
I was just using Chrome connected to my TV the first gen. And it randomly disconnected again.
I did complete factory reset too. Same thing.

I'm having this same issue. When connected to WiFi, things typically work for a few seconds, then they go to hell. It's intermittent, and it never works for longer than a minute.
In my household there a Pixel 2 XL, S9+, LG V20, and this Pixel 3 XL. All phone's, game consoles, laptops, security cameras, and even guest phone's work fine, but not the Pixel 3 XL. It does the same crap on my works WiFi too.
When I first setup the phone, I transferred data from my old phone. It took 22 hours to complete whatever tasks it had to complete when the transfer was done. That turned out to be the start of my wifi issues.
I've factory reset, reset network settings, deleted all sorts of caches, tried other networks, different network settings, even tried removing my case, and bought a new router. Nothing works...

I'm also having disconnect issues. One of the Pixel's wi-fi connection issues FAQs suggested resetting the wireless router to see if that cleared things up. I tried that after forgetting & re-establishing the connection didn't help. It made a substantial improvement, but it did not eliminate them. Obviously something else is going on.

Mine seems ok. The only disconnects I ever experience are my XBOX One disconnecting in the middle of games...

I tried this too with no improvements. I dont think this is a good solution though since my wifi doesnt work on any network i try. I work for a fairly large company, getting them to reset the hundreds of routers they have would definitely not work!

I had the issue too and read somewhere that turning on Bluetooth would stabilize the WiFi connection.
I tried it and it works for me.
I don't consider it a solution, but it might be a usable workaround for you.

I too have been encountering the issue with WiFi disconnecting. That said I only know it is happening due to picking up my phone and apps connected to my smart home report no connections. The phone has reconnected to WiFi but the apps are not recovering.
I am not using VPN ad blocking and my Bluetooth is on.

My Bluetooth is never off, but some devices use the same piece of hardware for both so I've done the opposite and shut it off to see if that might fix it and there's no difference whether Bluetooth is on or off.
Thanks for posting a new idea though!

Same problem here but only with AVM Fritz WLAN products. Access points from other companys work without problem.
Wi-Fi disconnects every few minutes, switches to mobile and immediately reconnects.
AVM Support say that they have tested it with one of the employees Pixel 3XLs and it's working without problems.
Google replaced my device but same issue with the new one.
I tried flashing the very first Factory Image and it has the same problem. And with Q the problem exists too.

I was able to find a solution for me. It was caused by AFWall+.
I uninstalled it and installed new beta 3.2. Setting everything by hand and now the disconnects are gone ?
