[Q] Possible wifi issue?

Hi,
I am wondering if it is normal that wifi speeds slow down after a certain time. My wifi at home can reach up to 22 Mbps down and say in a couple hours for example it would drop to 10 Mbps. Immediately I would restart my phone and it would be back up to normal speeds of 20ish Mbps. I do multiple back to back tests on speedtest.net app and my wired connections and other wireless devices are consistent.
My wifi does not disconnect and it has no problems connecting to other souces. At work i have the same wifi issues.
I have a Canadian Rogers Note 2. I am rooted and flashed to cleamrom 4.0.5, fully wiped and reset before flash with twrp. I have tried turning off power saving mode during the slow wifi transmissions and still have this issue,
I am lost as to what to do. Any advice would be appreciated.

Yes this is for me as well I have been on clean rom and now stock and it continues to do the same not a huge deal but I just noticed it last night im on mediacom if thats any help

In the meantime I have installed My Data Manager to see if there is any unknown wifi data transmitting while this problem is happening. When I had the phone bone stock I really did not monitor this issue.

I use the international rom and I notice YouTube buffers longer than it should than it chops shortly after. I just tried recycling wifi and now it's snappy again.question now is how long it will last

I notice link speed drops to about 5mb when directly infront of AP

I have been playing with this issue for a few days now. I can sort of recreate this by leaving the wifi range and entering. This will create that speed drop I described in my first post. By turning on and off the wifi toggle resolves this.
While using My Data Manager it shows no mystery wifi or data transfer in the backgound. Everything checks out in that aspect.

I did not notice a drop when infront of the AP.

I'm running stock Att and started having slow wifi speed after the 4.1.2 update. Toggling the wifi fixes the issue but it slows down again eventually.

yeah this blows. I don't know where the fault is. Running cleanrom 4.0.5 with its kernal. I don't believe I have really modified anything other than flashing the rom and a few zips here or there.
Normally it isn't a big deal but it really seemed to cause issues when syncing for the first time with dropbox yesterday. I had to keep restarting wifi. I think part of that was dropbox but 4 gb took literally hours to get done
I don't know if it happens on cleanrom 4.2.5

I am on CleanROM 4.5 right now and it behaves the same way. I did read on another thread that there is a possible fix by replacing the 'wifi' folder with the one from Android 4.1.1.
Here is the whole thread http://forum.xda-developers.com/showthread.php?t=1956155&highlight=wifi+problem
I have performed the suggested fix and will monitor the issue when I go about my daily routines.

Any new info on whether your idea worked? I'm experiencing the same thing you guys are.

confused about streaming

Had my N7105 for a few days now and I'm enjoying it, one thing though. Downloads and steaming is slow. Slower than my old BB9810 I'm talking about when I'm a at home using WiFi. Facebook takes an age to update, YouTube keeps buffering and I am connected to my network. Its not my connection speed that is just short of 70Mb! I put the phone in 'airplane' mode and just turn on WiFi and the speed is much better, no buffering or delays
is there a setting I am missing?
Also, I know the phone is 4g but vodaphone don't offer that here yet.....soon!
My phone is set to GSM/WCDMA is this correct? I have no option to enable 3G/4G.
Thanks in advance.

[Q]wifi dropping

I Can't find a thread about this, so I was go ogling and that doesn't really help. I am having major problems with my wifi it keeps dropping non stop and it's really annoying. I have my phone stock but rooted and was wondering is there any way to fix this? I know it's a Samsung problem but if I were to load this up with a rom should that help? Thanks in advance

Maybe it's your router or better yet the router settings. Have you tried changing any of those settings?

Am I missing something? How is it a Samsung thing? What kind of router do you have?

After looking all night I found a thread that fixed this. You have two choices really to fix or buy your router which I'm not going to do, or you can type in on your dial pad *#0011#. Then you click your menu button, click on the wifi option, and then disable the energy saver wifi mode. That made it so my phone wouldn't drop wifi connection anymore. NOTE: each time you restart your phone you need to turn the wifi energy saver off through the command *#0011#. Hope I helped some of you because this bug is truly annoying.

That stinks. I don't have any problem and I think this is only the 2nd time I've seen anything posted like this about the S4 (the S3 did have that issue and was common). I've never turned off any energy saver and mine stays connected 100% of the time. So you're saying either that or you have to buy a new router? What kind do you have now and what settings on it did you find out that cause this issue for you?

Right now I have whatever Verizon gives fios customers. It works perfectly for all my phones, tablets, and computer. Just not on my s4 unless I do the dial pad trick. I'll post a link on the xda thread when I get home on how to fix your router. It really does make me angry that I paid 600 for the phone and it does this. Hopefully Samsung fixes this soon since they acknowledge the problem

Btw here's Samsung acknowledging the problem.

Do you have a dlink router?
GS4

My gf has an S4 and has the same problem. We have a Netgear WNDR3500. So it's not isolated to a D-Link. She also did the dial pad trick and it seems to work for her as well. Need to find a script to run on boot to set the power save to OFF.

Yep. Just got mu device today and it is doing the same thing. Never had this issue with any of my other devices.
Are you connecting to a 5ghz or 2.4Ghz AP?

Did that too and nothing. Its probably my router. I will check and see what happens when I connect to another router.

Mine does this. Updated router firmware and seeing how it goes. Its an issue others have mentioned.

Go to wifi then open advanced settings bottom left then uncheck auto network switch. A pop up will come up check the do not ask again... I had the same issue with wifi this solved it.

Fixed or are using workarounds

Wish the aosp browser wasn't crap on 4.4. Also wish WiFi autoconnect worked in 4.3. Its really annoying that it randomly stops working until you manually open the WiFi menu. It still occurs even on cm10.2.0

what exactly do you mean wifi auto connect fail? It has been auto connecting for me? do you mean auto connect as in walk home, phone detected wifi signal and automatically turn wifi on and connect? if thats the case then i have no idea as ive never tried to do so.
Anyways.........anyone know a good cm11 kernel? currently i am using stock kernel and maaaan its missing so many functions D:

testing since yesterday, the rom is stable and whitout problems, don't had crash etc, just have a glich when u take a screenshot (in the preview) but the captured immage is fine.
I think the only thing that must be fixed is the browser, some times is choppy, double tap for zoom sometimes don't works and the video preview don't work.
I'm not sure but i have noticed a slight battery drain, more than the 4.3 stock:good:

It doesn't happen in cm10.1 or 10.0. It started happening when google changed the wifi framework in 4.3 to the always on scanning. Even with that setting disabled the scanning is still glitched.

What security are you using? wep, wpa2, ect.?

pretty stable nightly
Using CM11 nightly since yesterday. Had no issues except the screenshot preview. Screen shots are gettive saved correctly though. Also a little drop in battery life but maybe cause I am using it more. Is good for daily use.

I have flashed the nightly and there are 2 issues so far.
1. google now does not work
2. Spotify only plays 5 seconds then it goes mute while the playback continues.

I've found another issue: except for whatsapp and SMS I don't get any instant messaging notifications. Fb messenger as well as hangouts don't show anything in the status bar.
Funnily I use hangouts for SMS and it shows SMS...
Can someone confirm that?
Apart from that the only thing that really bugs me, is the glitch when playing music and powering off the screen. I would call it Playback-bug.
I dirtyflashed though. Too lazy to wipe, don't want to lose a lot of the stuff.
If nothing helps, I will wipe...

Its not the security thats the issue. The wifi radio stops autoscanning after deep sleep. Not everytime but enough to be a problem. I am not the only one with this issue.

Ive noticed this a lot lately as well.
My gnex is no longer on any carrier, strictly use on Wi-Fi now, and ever since 4.3 I experience same exact thing as you. (It also seems to randomly forget access points I've saved multiple times for no reason hahaha)
Haven't tried 4.4 to see if it persists yet
