Seem to be having a wireless problem - Samsung Galaxy Tab Plus

OK I have been trying to diagnose why downloads on my Tablet are unusually slow all of a sudden. For the first two weeks I had no problems but now downloads aren't as snappy anymore and the youtube app barely keeps up with the video.
I tried a multitude of things... changing the wireless channel, setting it to 5 Ghz, settings the power of the transceiver to default. All still give me strange download speed 5ghz was better but not where it used to be.
So then I opened the terminal emulator in Rom Toolbox and started pinging the router. Well what I found confused me even more.
I set the ping tool to ping 10 times. The first ping was fine about 8ms and it will steadily climb over the next 4 ping to 110ms! Then after that high ping it will drop back down to about 8ms again and steadily climb back to the 100s.
I don't get it what would cause this? This router isn't even 4 months old!
And just to verify I went on my laptop (wireless) to ping the router just to make sure nothing weird was happening and every single ping was 3 or 4 ms.

Well OK I figured it out. Apparently the GT 7 Plus doesn't like a channel width of 40mhz. At 20mhz it happily downloads anything. The pings are still quite high though but at least it doesn't take 3 minutes to download 10 megabytes on this thing anymore.

Bug discovered?

So aside from the backlight problem everyone's having (replacement will be delivered monday), I noticed that wifi crapped out on me early on, to the point that my DL's were about 2-300 KB/s and uploads were at about 700KB/s. Factory reset fixed this.
Fast forward a few more hours, I decided to view some youtube clips via the youtube app and the issue occurred again, and that's when I remembered that when this happened the first time, I was using the youtube app.
It seems like using the Youtube app on this phone completely cripples the speed of a wifi transmission --possibly even 2G/3G/4G (wasn't able to test).
Factory reset fixes this. Can anyone else test this out to confirm if it might be happening on multiple phones?
What are the bandwidth speed caps on your wifi? What is your normal down and up speed?
no caps on wifi, I setup QoS filtering to prioritize my xbox 360 and flash applications. It's a Linksys G router 54 Mbps with Tomato firmware
normal speeds provided by ISP is 13-16 down and 1-2 up on an average day.
Alright I just tested and before using youtube this is what I get on speed test (mbps):
wifi:16 down, 1 up
4g:4 down, 1.3 up
then I ran a video on youtube:
wifi: 21 down, 1 up
data: 4.6 down, 1.1 up
Youtube didn't affect my data speeds. You should call t-mobile CS because the issue you're facing doesn't seem normal(continues after factory reset)

wifi cm7 fix for touchpad

i believe i found a fix for the wifi losing connection to hour tablet. When you tablet loses connection with wifi let it run dry till it is dead on battery than the wifi will start working again. This has worked multiple times for me.
When you say "let it run dry" you let the battery run till it's dead? That will take hours to drain and then time to charge. Please explain.
well what happened to me was that the wifi would no longer connect so what i did i let my touchpad run till it was dead than recharge and whalla. The wifi is working again.
That would be a work around and not a fix...

well it is work around. Currently there is nothing that "fixes" this so this is the closest thing to a fix.
I've my TouchPad and HD2(HyperDroid) both on wifi issue.
Letting your pad go dead then recharging is no different than performing a simple reboot. Reboot your tablet instead. Much faster and yes it does seem to connect instantly. You can also "forget" the connection and then reconnect.

It isn't always as simple as that, rebooting causes wifi problems on mine.
The workaround that works for me is setting my router to use channel 6.
I have had some success getting my Touchpad to stay connected.
At first I was using a D-link DIR-655 wireless N router that would not stay connected reliably. One of my friends was selling a Netgear WNR-2000 N router for $20, so I tried it, and it works very well, stays on channel 1 all the time. I get about 20 Mbps download speed over cable. Not bad.
But I also had the "1/1/1970" issue when rebooting sometimes. This was a real pain in the butt to get fixed. Tried all kinds of different settings, but nothing seemed to work reliably. It causes SSL errors and certificate errors on websites. Someone, somewhere suggested Clocksync App. and since it runs with superuser permissions at boot, my problem is solved.
I use SetCPU app to overclock to 1.7ghz at boot, and the Clocksync to set the time and date. This thing is a rocket ship compared to any of the tablets I have seen. BTW, I'm running CM7 Alpha 3.5. I will probably try ICS when it's released, but for me, I'm happy already.
Hope this helps someone else.
Just installed CM7. First boot Wifi was fine. I had yet to install the Google Marketplace files. I connected and browsed the internet for a bit.
Once I installed these and rebooted Wifi is now dead. You can see it attempting to restart multiple times. I have two routers an Airport Extreme and a Engenious Portable router and neither work. I don't think the router is the issue. When you try to make changes to the settings on the Touchpad it freezes up and throws this error:
Activity wifi settings (in application settings) is not responding.
You are then asked to Force Close or Wait.
Hoping there is a solution because without wifi well Android is pointless on this device. No other installation issues occurred.
Thanks!
EDIT: I changed my Airport Extreme Router to Channel 6 and the Touchpad was able to connect. I will try my other router as well to see if this resolves the issue.

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 :|

Chrome and other browsers really slow, but only on WiFi...

For several weeks now, I have noticed that Chrome takes 5 - 10 seconds to load almost any webpage, but only if Wifi is on and connected. On LTE, its no more than 2 seconds to load a new (non-cached) page. This includes my home network (50 Mbps, Linksys EA6100 Router), work (Cisco waps, 10Mbps), and a university network (Speedtests show 160Mbps). I was getting this issue on Stock 5.0.1 and I'm still getting it on Cataclysm 5.0.1 (ElementalX Kernel). I also cleared Chrome's cache and it got a little better. Just a little though. I downloaded Firefox and it does pretty much the same thing. I'm at a loss.

Android M on Nexus 5 consumes all my home Wi-Fi bandwidth

This is my story:
I have finally fixed my Nexus 5 that had a broken motherboard issue since Septamber 2015 (I didn´t find anyone who could fix it here in Uruguay).
Once It turned on it connected to my home's Wi-Fi and starting suggesting uploads. And I did, first to Android M, then January 2016 fix, then February's and March's.
And then after waiting for all the apps to update, I started using it.
I quickly noticed the battery drain regarding wifi and I looked up in the forums and fixed it (i think). But then some other things came up, but, the most important is:
When I connect my phone to my home Wi-Fi, it just takes all the bandwidth, and if I do an adsl test on my pc, it displays the downloading speed down to 1.x instead of 15.x Mbps.
Thing is, when I am connected, even the internet speed of my phone is slow. and when I turn Wi-Fi off on my phone, my pc´s Wi-Fi´s speed is back to 15.x Mbps, and my phone on LTE has a normal internet traffic.
I have tried to search for this issue over the internet, but maybe it is a translation issue not finding the right word, but only the "battery drain due to wifi issue on android" comes up.
Any clue?
Thanks.
