Wifi Issues

I dont know if anyone is experiencing this but randomly my G Tablet goes insane with the wifi. It goes into an almost infinite loop of turning wifi on, scanning, connecting, and disconnecting. It doesn't happen often just that when it does it becomes nearly impossible to correct.
This happened on my first G Tablet running TnT Lite 2.2. I had returned that one and recently this one has begun go do that too on TnT Lite 2.4. It has happenned in three different networks. The only remedy seems to turn airplane mode on, turn off or move away from any networks, turn off airplane mode, and then turn on wifi again. Either that or the tablet freezes and reboots on its own.

Yes, I just posted that this happened to me this morning on Vegan ROM beta 3. That's the first time it's happened. I rebooted, and it happened again on wake. Rebooted again, and it hasn't happened again since.
So two times out of maybe a hundred sleep/wake cycles for me so far. Not sure what to make of it.
This never happened to me with ZPad ROM, which I ran for the first two to three weeks that I had my G Tablet.
My understanding is that ZPad uses a different wifi driver than TNT Lite and Vegan ROM, which share the same wifi driver. So I suspect this is a driver glitch of some sort.

This happened about 4 or 5 days ago to me. I rebooted and it never happened again.

I've seen this a few times with TnT Lite 2.4 as well.

Happens to me all the time on tnt lite 2.4. Most often just after waking from sleep. And it really hates my 802.11n access point. Happens a lot less on a b/g network.
Anyone else getting really miserable signal strength unless you're in direct line of sight in the same room?

I have the same problem with the continuous loops. Even turning on airplane mode doesn't do the trick anymore. I have to fully power down and then power up again to rectify the issue.
It has problems connecting to my Home WiFi but I can tether using my Evo's Hotspot app with no problem. Very strange.
I use the TNT Lite 2.2 ROM.

I am having the same problem with tnt lite. On unsecured routers it connects perfectly. With security though - no go - endlessly connecting and disconnecting. Turn the security off the router and it connects fine. At home, forcing a static ip seems to work most of the time but elsewhere - forget it. It is the one thing that is spoiling my otherwise excellent experience with the gtab. It seems like it has been a problem for a while but no ones seems to have addressed it in patches, etc. If I knew how, I'd do it myself.

I'm experiencing some Wifi issues. Wifi is on and appearing to receive, connected to my network yet unable to access the internet.
The fix:
1. Go to settings, Wifi and settings, instead of choosing from a scanned network input my own SSID and encryption code.
2. Choosing "never" for under the advanced settings, as your wifi sleep policy from the drop down list.

wireless connectivity data
So I've been pissing and moaning for a week now about sketchy connectivity. Today I did two things, both of which "fixed" my problems. At work I reset the Netgear wireless to factory defaults then configured it for encryption and the gtab happily connected to it for the rest of the day. At home I replaced the netgear with a Linksys wrt54g running tomato o/s and theconnection was immediate and stable. Go figure. So if you are having wireless connectivity issues you may want to check on your router. Curiously, my Droid x has had no problems with any of these routers. Good luck!

Mine seems fine all through the one story house with alumenim siding, but I use a b/g router. i took the tablet on a cross-country train (Denver) and i had the choice of a dozen or so signals from the sleeper whenever we were rolling down the tracks through towns and cities. Actually I am quite surprised at the reception coverage. At the local B&N, i could see networks of several adjacent stores and their tech guy was surprised to see what the WiFi Analyzer app display showed him.

3.2 wifi disconnection..?

Anyone else having wifi problems after updating? I didn;t have problems before, but it seems that after 3.2, my wifi stops every couple of minutes or something like that. I don't know if it's my own wirelss's problem, so when I get back on campus, I'll attempt downloading and seeing if it gets interrupted again.

Yep I'm having the same problem. Keeps kicking me out of my PocketCloud remote. Thought it might just be me. I've noticed the Wifi symbol stays grey a lot when it used to stay blue. It's not my network, the only change was the update to 3.2.

Yeah... it's grey and it keeps disconnecting me while I try to download an episode..
(stock 3.2)

I got kicked out of my home Wifi several times last night after updating to 3.2. I didn't have this issue on 3.1. What a total disappointment...

WiFi with 8.4.4.11
Did you install 8.4.4.11 before installing 3.2?
My tablet came back from RMA with firmware .11 installed, but before 3.2 came out. I noticed similar behavior with the WiFi. In my case it never found any networks (I'm guess some wire got messed up when they fixed the power button issue). However, when on the WiFi page in settings normally it says "scanning" under WiFi when looking for a network. On mine it would say "scanning" for a second and then it would go away, then it would say "scanning" again, then disappear, etc. Maybe there is an issue with the WiFi driver?
I'm hopeing the tablet will be back next week (it was in repair status yesterday). The first time I sent it in it came back with a pretty good description of what they did to fix it (its just a bummer they broke it at the same time).

What are you Wifi setting, especially the disconnect settings? It could be that the update changed the settings.

Hmm, I checked it because I saw another thread saying something similar, but it was still marked as "disconnect when screen is closed." I also tried unchecking it and rechecking it, then turning wifi on and back off to see if it would fix it. (It didn't!)
Well, I'm hoping it will be fixed by Asus sometime soon, but it's not too big a problem at the moment since I don't HAVE to watch those episodes. :/

Mine is set to never disconnect. Even tried changing to a different setting and back.

Confirmed. Had this happen since the .11 update.

I may try a wipe and restore. Considering going ahead and rooting if it comes down to swiping. Anyone tried either?

yeah I might as well root if i have to reset everything...

Yes, same problem...disconnecting for about ten seconds every two minutes or so. Makes listening to radio quite impossible...
Have done resets and changing wi-fi channel to 9, doesn't help.

I've noticed this, but it hasn't happened very frequently. For me, it seems to happen mostly during when I had the screen off (which I had setup to disconnect whenever the screen is off). I recently just changed it to never disconnect, and I haven't seen it happen in the past 10 minutes or so, but that could just be me.
I do agree though, it seems as if there is some kind of bug here as well.

I had a similar problem before 3.2 ...i fixed it the day before the update. I forced my router to not be bonded to a channel and set it to auto.
Youtube constant buffering was fixed.. now it downloads the videos quickly and no buffing after the first time.
Also my apps like CNN that have alot of visual pictures in the main menu load up instantly and downloads are lighting quick. No interruptions, re-downloads or anything. Even when apps are updating..Games like Dungeon defenders that has alot of initial downloads pulls the data without stopping.
I suffered from disconnections before i set the router to Auto and choose a channel on its own.

No issue here.

That is exactly what mine is doing. Has anyone contacted Asus?

I think I have a fix. I tried the old assign it a static IP on the TF itself. Icon stayed blue for over 5 mins without turing grey. I'll have to check my PocketCloud tomorrow and confirm the fix.

I've been having the same issue...... every few minutes it says no connection. It also seems like I have fewer bars on my wifi signal icon too.... hope a fix is found soon because it's frustrating.

Well, I tried it on campus, same thing, disconnects within a download of an episode.. (like 4-5 minutes??). Oh no! I'll never get to finish Triumph in the Skies..

It happens to me too. It is quite frustrating.
I have already tried to assign a static IP but with no success.

Random WiFi slow down

I'm noticing strange WiFi issues, in that my data speeds keep slowing down to a standstill for no reason.
In fact, when I first booted the device, and started to install my apps, I wondered why there were downloading so slowly, so I installed "SpeedTest" and sure enough my data speeds were like 1.5mbps. To test that my network hadn't just suddenly gone crazy, I ran the test from my laptop and that confirmed normal speeds.
To remedy this, I changed my advanced wifi settings to just use the 2.4 ghz signal, then changed my router settings (a BT Home Hub 3) from smart wireless (auto changes channel to the "best" channel to just remain on that already pre determined best channel.
I then immediately saw an improvement, as it was downloading now at about 27mbps... and so I thought I'd cracked it.
Apparently not.... It regularly goes back to downloading really slowly, and sometimes, messing with all those settings again doesn't do anything to improve the speeds.
Anyone else experiencing this, or has any insights as to what is going on? could it be a wifi driver issue, which may be rectified in later updates or baseband versions?
Here are some pics to give you an idea... all from the same network

Back to awesome after changing router security settings... I wonder how long it will last this time?

Exactly the same for me:

I'm being sent a replacement but I can't say I'm convinced that one will be any different.
This issue occurred on my BT home hub, a tp-link access point, and the access points where I work.

WiFi issues

Anyone else with WiFi issues? 90% of the time I have no problems but 10% of the time it seems the connection hangs. Data transfer will pause and resume 30 secs or a minute later. I have tested this with speed test and was able to reproduce. Happens on both my 2ghz and 5ghz networks. I am rooted but I'm going to do a factory reset to see if issue persists. I do know it's not my WiFi as my other devices have no trouble. But this is quite annoying.

Are you by chance using an Apple router or access point? For some reason, they don't seem to play well with Android devices, including my M8. I've had a similar experience with 4 Android devices and 2 different Apple routers. The devices continuously disconnect and reconnect.

No I'm using an Asus ac66. The funny thing is the connection doesn't drop. It always says connected. The data just stops flowing and then starts again. For example I'll run a speed test and the download will pause then start up again. Very odd. Never had a phone do this before

I've got an Apple Airport Extreme. I also have several Android devices. Have had many that I no long have or use. I've never had any problem with my wifi on any of them. I have to wonder if your problem isn't related to something else. Or, possibly your router needs to be replaced. Might be a matter of settings too. But, like I said, I've never had any problems with mine.

Within the "Advanced Wi-Fi" settings there is an auto-enabled option called "Wi-Fi Optimization" which minimizes battery usage when Wi-Fi is on. I assume this monitors for extended periods of inactivity (screen off, no active downloads, etc.) and temporarily disables/hibernates Wi-Fi activity.
I've kept this option enabled and haven't had any issues so far, but maybe you could try testing with/without this setting enabled? Another thing to try would be checking highly-used radio channels in your area with an application like InSSIDer and making sure your router is broadcasting on a low-use channel. I see no correlation with the radio channel and your new M8, but it's worth a try

I have the same issues. and ive turned off wifi optimizaiton, ive set my wifi control frequency to 149, ive tried to switch between 2.4 and 5ghz. i feel like my issue is with the phone not picking up the wifi signals very well... we live in a brick house, and the asus ac68u sits right in the middle of th house, and my room is only right around the corner. everyone elses phone picks up 5ghz or 2.4ghz frequency fine in my room, even my gf's M8 (we bought ours from verizon same time for the deal). i literally get wifi in my rom 10% of the time or its choppy and slow. so everytime im in my room i have to switch to cellular :|

Bluetooth causing extremely slow wifi

So I've had my m8 since launch, about May of 2014. I've never once had a problem with my wifi, until last week. All of a sudden, I noticed all of my wifi connections (home, work, etc) are all extremely slow. Speed tests are barely getting 1mbps down or up, and the test itself is very erratic, bobbing up and down the whole time. All my other devices are fine, and nothing with any of my wifi connections has changed. I uninstalled about 3 apps that I had installed within the last month, with no change. Verizon sent me a replacement m8, and I got it yesterday, loaded up all my stuff, and low and behold, still slow wifi.
After talking with numerous Verizon techs, they can't solve it, even after multiple factory resets. However, this morning I saw a post while googling it, not an m8 but still android. They said that if Bluetooth is on, but not connected to a device, it could cause issues. So I turned my bluetooth off, and speeds were perfect, getting exactly what my internet connection is. Turned it back on, and back to 1mbps.
So one, why is this happening? I've read that the bluetooth and wifi antennas are the same, and that could cause interference, but it should not be this bad. Second, why did this just now all of a sudden start? I didn't usually leave bluetooth on, but I got a new car about 3 months ago, and decided to leave it on to automatically connect when I'm driving. But it was fine until last week, why the change?

Have you discovered anything new? I've had my Verizon m8 since April 2014 and have always left bluetooth on for my fitbit to sync. I only recently started having problems and can't identify any recent update that happened this month that would cause it. When bluetooth is on and a device is connected my wifi performance is very slow - 100+ ms ping, 1-2Mbps up/down doing a speedtest. Turn bluetooth off and speed test again then wifi performance jumps to 20Mbps up/down with 12ms ping times to the same speedtest server.
I have factory reset my phone 3 times, changed wifi channels, tried 2 different routers and 1 access point. None of the wifi changes affected speeds until bluetooth was turned off. It seems to be a little quicker 3-5 Mbps with bluetooth on and no devices paired but still that's not acceptable.

I too have had bluetooth on for months to be able to connect to my car, never had a problem until about a month or so ago. I did two factory resets, and everything seemed to work fine, but after a day or so, when all my apps were back on the phone, it would start up again. I have a hard time believing a specific app is doing this, unless it was one of the HTC Home updates or something.
Verizon sent me a replacement M8, I got all my apps on it, and the same thing, after a day or so it's super slow with Bluetooth on, horrible ping and less than 2mbps down and up.
So then I contacted HTC directly, did all their troubleshooting, factory reset, and it's still there. They sent me a replacement as well. I turned it on, but did not put my sim into it. I spent 2 days with it, and only downloaded the Speedtest app, nothing else. Speeds are fine with bluetooth on. I then downloaded the rest of my apps (I actually do have quite a few apps, so if it's one of them it will be a pain to figure out which one). It's been two days now and speeds are still good with bluetooth on. Later today I'm going to offically move over to this phone and put my sim in it.
It's just really frustrating to keep turning bluetooth off and on again, and there should be no reason for this to be happening out of the blue all of a sudden.

Strange issue, but from how you described it, it must be a 3rd party application. What I would do in this situation, is do the factory reset, and download 5 apps at a time. Until you narrow it down to the 5 apps that are causing the issue, then you can narrow it down much easier out of the 5 applications. A pain, yes. but once you figure out the app that's causing the issue, you may decide you don't need it, or you only use it once in awhile and can remove it, until you need it, or possibly download an app ops application from the Playstore and remove the Bluetooth permissions and see if that fixes it.
Best of luck.

Seems to help...
I just tried the solution offered in another forum (xda won't let me post the link so I'll copy and paste the information here:
Open page with the available "Wi-Fi" networks (Settings, WI-FI)
Tap on the "3 dots" in the upper right corner
"Wi-Fi Direct"
Tap on the "3 dots" in the upper right corner
"Rename device"
Replace "Android_ed2c" with "HTC One" (or whatever you want) and hit "OK"
Before doing this I had a 300ms ping when Bluetooth is on, and very low bandwidth. Now with Bluetooth on the wifi ping is around 50ms (normal for my home internet) and the bandwidth is back to normal. Time will tell if it sticks, but so far so good!

So I had been running all my apps on my replacement phone for about a week now, and have had no problems. The other day I officially swapped my sim card into this new phone, and for two days now, it's been fine. Bluetooth and wifi are on constantly, and I see no issues with bandwidth. So who knows why the last two devices had a problem, but for now it seems to be fixed.

Having the same issue, originally posted on reddit and then found this thread: https://www.reddit.com/r/techsupport/comments/3kv6z6/wifi_issues_with_multiple_phones/
Turned off bluetooth and it's fine... Will be experimenting with my gf's m8 this weekend.

Same HTC M8 issue - very slow WiFi when Bluetooth is running
Same problem on an HTC M8... speedof_dot_me speed test shows 96 ms latency with D/L at 0.07 mbps (really!) on an 11 mbps router. Turned off Bluetooth, and voilla! Latency dropped by 85% and WiFi speeds increased by a factor of 60! I suspect an HTC issue since an August or September update... since this wasn't occurring prior to August.

Verizon sent me a replacement M8 that was on 4.x.x android. I updated via on-air update (not rooted) to Lollipop and installed all my apps. Everything was fine. That night, it did a security update and, since then, my wifi+bluetooth were horked when turned on together.
Do, I did a factory reset (which doesn't undo the updates), but since doing the factory reset and installing just the basic Play-store updates 24 hours ago, the problem is not back.
I'm going to slowly add back my normal apps this time.

Solved on one plus one
Hello, i had since two weeks the similar issue. when bluetooth is switchef on (unconnected), wifi is very slow. in the past this different, so no issue with hardware and frequencies. Finally, I found out that it was linked to an App that accesses Bluetooth.
In my case it was the App Accu-Chek, I read in a big forum that it was linked to a Garmin app.
Uninstalling the App solved the issue.
My wife has a similar issue on Stock Galaxy S4 mini with that App.

This is definitely app-related. I tried force closing out of a bunch of apps that weren't related to the video I was playing and it seemed to fix the bandwidth issue with bluetooth enabled. Guess I'll need to experiment with closing certain apps until I find the culprit.

I was having this same problem. It looks like the RetailMeNot App was the culprit for me.

You sir deserve a cookie. Thanks for pointing out the worst app of 2015.

Solved on my Phone!
I used to have the same problem. I am having a Sony Xperia Z1 Compact and a Smartband Talk. At the beginning everything was fine but after sometime (strongly caused by a software related issue) I begin to face the same problem. While bluetooth is on WiFi bandwith dropped to a very little amount (around 0,02- 0,01 Mbits/s). Then I read somewhere, about how to verify whether it is a software or hardware issue via checking it in the Safe Mode. So I unpaired by smartband talk and uninstalled the smartband talk software (smartband talk requires a bluetooth connection for functioning). Then restarted my phone in to safe mode by tapping and holding the power off on the shutdown menu. I downloaded the smartband talk software and turned on my bluetooth and paired my smartband talk again. Then restarted my phone in to normal mode. And voila, problem solved.
It is not a guaranteed method but worth to try.
Wish you good luck.
