[Q] Wifi Dropout Problem Persists: Someone, Please Help!

I'm getting really frustrated now. This problem is a real nuisance for me, as I use my Desire a lot solely for this purpose.
In my room, the wifi signal has always been pretty weak, generally only getting 1/2 bars. However, the connection is stable and still about 6mbps. This is never usually a problem for my Desire, it picks up the connection and everything works great. Stock Froyo, Sense Froyo, Sense Gingerbread, Sense V2 Gingerbread, Miui Froyo and Miui Gingerbread all operate flawlessly.
However, I now have a bit of a problem. It seems most Gingerbread AOSP ROM's cause the wifi to play up. I have tried GingerVillain, Oxygen, Redux and finally now my favourite CM7. The wifi constantly drops out and loses connection, and then takes a good 30+ seconds to reconnect. The dropouts can be as frequent as every few minutes, and generally it never lasts 4+ minutes in iplayer without losing connection. If I am just casually browsing, I don't notice. But when I am watching something on youtube or iplayer, the constant dropouts make the experience so horrible it isn't worth the effort.
What's more, there is some odd bug with the iplayer app where once a dropout happens, the audio and video goes out of sync and so on etc. All in all, it makes streaming video unusable, and this was a main reason for me buying a smartphone.
I really don't know what the problem is, but I really would appreciate some help. I would say it was a gingerbread problem, but as stated above, there are many gingerbread roms which don't cause me the same issue. Similarly, I've used an array of different radio's and kernals on each ROM. They make no difference. It depends purely on which ROM I am using. I've tried resetting the bt home hub, restoring it to factory, changing security type, moving it's position and so on. I'm pretty sure it's a ROM / Phone issue though as it works fine with other ROMS. Phone wise, I've set wifi policy to never and set a static IP address. It makes no difference. I still get wifi dropouts!
For reference sake, I'm using the latest stock Radio - 32.49.00.32U_5.11.05.27 and Kernal 2.6.37.4-cyanogenmod-82245..... and obviously CM7 7.0.2.
Please someone help? I'm actually considering upgrading just to solve this. It is absolutely doing my nut in, and I am totally out of ideas or solutions.
Thanks.

Maby a weird thing but on what channel is your wifi broadcasting ?
I had almost the same problem when my wifi was on channel 12. Now on channel 3 there is no more problem.
Not that any other wifi's broadcasting here. It is just that I've got the feeling that android has a problem with "high" channels.

It was on 10 and 11.
I'll switch to 3 and give it a try. Also, I'm going to try flashing the Gingerbread Sense Drivers and RIL.

Hi,
I've also had a similar problem for quite a while now (1-2 weeks). I used my wireless connection on my standard out of factory ROM on my home wifi network, my families wifi networks and my work wifi networks without _any_ problems.
When this problem started acting up I'd start my wifi connection, it would work for like a minute or so (not dependant on the amount of data transmitted or something, idle would last as long as while downloading), and then lose connection.
The strange thing is that it indicates it is fully connected at full strength but can not establish _any_ internet connection whatsoever.
My 3G connection to my network (I live in the Netherlands) works nicely, but it isn't as fast as wifi, so this limits me quite a bit (especially at work, indoors).
I've just tried to upgrade to CM7, but doesn't give any better results. I haven't tried upgrading my RADIO, but I don't really want to if I don't have to.
Any clues what I could do to fix this?

I'm experiencing similar problems.I changed from channel 11 to 4, but it really hasn't helped. I have also set up a portable wifi (netcomm). It runs on channel 3. The network sim is quite slow but the signal strength is much steadier. My faster speedstream completely drops out. I understand this "pulsing" of signal is normal, but mine is beyond the pale.
My acer netbook doesn't demonstrate any dropout issues.
Im running an A501 3.0.1. No upgrade yet for me here in australia. But, I'm wondering if this is just poor hardware.

could try a different Radio.. the latest stock one from the new official gingerbread is in my signature..

further to my difficulty with wifi drop outs, I'm pleased to say that it appears that my problems probably are related to my home wifi, a Speedstream.
I'm currently spending a week on a houseboat and I've been using a netcomm myzone wifi fitted with a sim card from a prepaid Dodo broadband usb.
I've not had any problem with it. Granted, I've had it close by, but it still seems to work fine when I'm at the other end of the houseboat.
So my acer A501 seems to be behaving itself here. Perhaps, something is causing the speedstream to vary it's signal strength so drastically.

@OP - I posted a thread a few weeks ago about having exactly the same problems as you with AOSP ROM's and weak wifi signals. Once I went to a Sense ROM the wifi signal was great. I prefer the AOSP ROM's so I upgraded my Radio to the latest version but it didn't help at all, I didn't see any change when using wi-fi analyser.
I'm currently using CM7 ROM and just putting up with the weak signal. I'm glad it's not just me though.

[Q] Slow wifi on CM9

Yesterday, i have unlocked and rooted my phone to put CM9 nightly on my galaxy nexus[GSM]. Everything works fine but i have one issue, the wifi speed is really slow on my phone.
this is the rom that i flashed on my phone.
http://forum.xda-developers.com/showthread.php?t=1398495
I have tested on speedtest.net and i am getting less than 0.5mpbs. I have looked over my router and other devices, they are getting 5mpbs. Is this an issue with CM9? On stock settings for the nexus i get 5mpbs.
Is there a fix around this?

What is your broadband connection rated at? 5/10/15/20...mbps? If you are rated at 15 or 20 and your only getting 5 on other devices you could have a router issues.
Does the speed get any better when you are within 5 feet of the router?
Do you have multiple Wireless Routers/AP's?

there is no difference if i am beside or 20 feets away from it. I still get less than 0.5 mpbs. There was no issue when i was using the stock version of GNexus 4.0.2.
I only have one router.
I have managed to fix the problem, can a mod please delete this thread?

I have the same problem. When I restore back to stock, the problem goes away. I do have the FD01 radio firmware installed.

How did you fix it? You could at least share it with all the people who tried to help

Hi folks
I was having the same problems. I just upgraded to 9-20120511-NIGHTLY-maguro and my wifi issues have gone.

Try rebooting your router. I've been using CM9 for weeks now and the only time I've had issues were with my router.
This isn't even the fastest.. just a random test. CM9 Nightly 5/11.

I have the same problem after I assigned my phone a static IP on my home router. Search on MAC randomization for this issue. There are several kernels that fix this. I believe Franco, Trinity, and Imoseyon will work. I wish the stock cm9 kernels would get fixed for this issue.
Sprint GN, Tapatalk

Do you have some sort of QoS setting on your router keeping it from providing the speed to certain devices or something like that? I agree with the others, first thing I would do is factory reset my router.

Having a similar issue my epic is doing 25mbps on a 30mb line but both of my gnexs on different roms are only getting g 10-12????

I've also noticed that my Wifi performance is seriously degraded and very slow. At first I thought it was my connection, but further testing narrowed the issue to my Gnex only. I get very long 1000+ms ping times using the speedtest app and get a stuttery 1-2mb/s down and up, when every other device in my house (6+) is showing upwards of 20mb/s down and 2mb/s up. I have replicated the horrible ping and download times from various wifi hotspots.
To test further, I reverted to a backup nightly with no change. I went back as far as my 04/29 build and the problem remained. Maybe I just didn't notice it before, but I'm not certain. I have even flashed other ROMs such as AOKP and speedtest showed superfast results.

Wonder what AOKP did to it because myself and many others finds wifi to suck on the stock roms.

The wifi problem goes away when i use a kernel that addresses MAC randomization.

Figured out the cause of the slow wifi
I found out what the issue was with my wifi slowness and awful ping times.
I re-installed the latest Nightly and this time I did a "wipe data" (wiping out all of my apps) and my speedtest results were awesome again. Essentially a clean install. After reinstalling my apps one by one, I've been running speedtest each time and found that Doubletwist/Airsync was the cause of my slowness. Uninstalling DoubleTwist/AirSync and then rebooting fixed the speed/ping issue right away. HTH.

You could also try AirDroid (https://play.google.com/store/apps/details?id=com.sand.airdroid) as an alternative to upload/download files to your phone.
Works great for me ^_^

Z1C WiFi Issues? Speed/Stability

Hi all,
Not been around for a long time so its great to be back
Recently got the Z1C on Contact, frankly its the biggest regret I've had with a mobile device.
Is anyone else having WiFi speeds slower than dial up?
My download speed is < 250 KB's
Any1 else had this? If so does any1 know a fix?
Thanks

I don't have that, neither on 2,4GHz nor on 5GHz. You could try the unofficial DooMLord kernel, it mentions "custom built wifi wlan modules", dunno if that helps.

I'm not currently looking to Root/Unlock/Flash anything.
I'd just like my Stock Z1C to actually work with WiFi.
Its not exactly difficult, its seriously annoying me now, why is it so slow?

.. sorry just saw my solution doesn't help you and I don't know how to delete a reply...
but anyway, have you tried to close all apps on your phone?

my wifi works great too .. what rom do you use? latest .757 ? download .761 or 757 FTF and try to flash via flashtool .. No need to unlock bootloader or root, but you will lose some data if you don`t make any backup
you have a software problem there ..

I'll check it out when I get home but I never have Bluetooth on so I'd be surprised if it was that.
I have a gaming router which is extremely powerful and all other devices/phones work perfectly so I know that the Z1C is the bottleneck.
Any other ideas if its not the bluetooth?
Thanks

I've not had any issues with WiFi or BT, which is always on on my phone. I do use 5GHz for WiFi.

Have you tried restarting your router?
Does it go slow with every wifi? can you test it on different wifi and see if the problem is with one type of router?
Don't think I've seen anyone ekse with this problem, although flashing the .757 update messed up my bluetooth (then .761 fixed it).

Thanks for getting back to me
I have tested it on my work WiFi, I don't know whether it is coincedence, sod's law or normal but the WiFi on my Z1C at my work is absolutely rapid!!
I've just updated an app to test it, and it was at around 5MB's which is brilliant for me !
However, work WiFi is a 100MB's connection speed, where as at home I believe its around the 12MB's mark (geographic limitations in place here >.<).
From this I see only a couple of conclusions:
1 - Z1C and my home router just don't get along.
2 - As the WiFi speed is so much higher at work, so is the Z1C
or that theres no relation between the WiFi speed and my device but there is an issue with the Z1C WiFi itself?
I'm presuming its the first?
Thanks again!

Hi there,
I'm still on totally stock ROM.
I've done some testing and I believe it is on every router/internet but is very inconsistent. Sometimes its very speedy, others it will drop to almost unusable speeds.
I think I'ma just get rid of this terrible device, very disappointed in Sony. Here are some of my issues:
Phantom Touches
Unresponsive Touch Screen
Constant Crashes
Phone CONSTANTLY answers in Loudspeaker
Screen will not wake up
WiFi Speeds Totally Unusable

Just update to 14.4.A.0.108. It's also stock, official. You do not loose data while updating and it takes merely 10 minutes of "sitting back and relaxing"
As for wifi issue, did you try disabling wifi optimization fetaure found in advanced settings?

Have to be honest,
I got that fedup with all the issues on the phone, I sold it and bought an iPhone.
(Waits to be shot).
However I must say, iPhones feel very nice nowadays, nice and snappy etc.
But yeah, I'll still be hanging around these forums helping people out etc,

Hey that's a new phone just so you know because this is not acceptable.
Not sure about reclaims in your country but it should be valid in most?
Mine did about the same as my PC/PS4 = 60-95MBps, that is until yesterday
Both bluetooth and wifi are stone cold dead so I though I should reflash my ROM(Aur) and rushed it when I realized whilst doing the same 'ol start guide for the hundreds time I forgot to flash recovery :victory::fingers-crossed:

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!

a5 2017 wifi problems

I am getting really bad wifi connections and the phone is very slow at browsing refusing to load pages fully. Running Speedtest by Okla says "network communication issues". I get this problem on wifi in public areas and at home. It does not seem consistent. I got so fed up I factory reset the phone. I connected to another wifi router at home and so far everything seems fine. All other devices work fine with public wifi and wifi router at home including Samsung J5 and S4. Any ideas?

I have sometimes wifi is reconnecting, but most of the time I have a good connection.

I'm having weak wifi reception with the A5. When placed side by side with S4 and S7, the A5 has the weakest wifi signals. Speedtest confirms this as well.

Yeah, definitley weaker reception, i compared to my Htc 820 and Sony m2 aqua and it was pretty weaker all of them are on stock roms.

Well, me too. Weak reception when just a littel away from the router. Randomly loses signal force, can't see any router, then, connect again... It seems to get worse when heavy using internet, like watching YouTube videos... But near the router, everything stays normal... My moto g 2014 never had the problem and I'm in stock rom too...

It strangely seems to be YouTube app who causes problems, because when I stop watching videos the signal force get actually more stable, even full in places it doesn't get full when watching YouTube...
But it still seems to suffer from some instability at its natural... When I tap play in youtube, the signal drops to almost zero...
I would like to know what is happening, because it isn't a cheap phone, and even moto g 2014 has got a better wifi

It also seems that demanding wifi in general causes signal to get weaker... I never saw something like that, signal strength doesn't get affected by use, only bandwidth...
Any other experience?

Similar issue with my A5
I recently bought an A5 2017 aswell and my phone also has HORRENDOUS wifi , not just that but for some reason it would randomly stop reconnecting and stop showing the wifi router or anything and the wifi connectivity doesnt turn on , and then if restart it but it would hang mid restart and then id have to hard reset it by holding the power and volume-down button , and this whole procedure happens like once or twice a day so ita really frustrating. Especially because this is a New phone btw, my wifi is perfe fly fine because i ha ve other technology and have previously used many huawei phones which have perfect connectivity and this was my first experience with Samsung, any help would be much appreciated thankyou !!

I am having the same issue as the person above. Pages will refuse to load until i turn off wifi or refresh the page. There are duplicate posts coming up on facebook. Like 4 or 5 posts repeated before new ones. Twitch constantly buffering. Tried on mine and parents wifi with same result. Both were always and still are fine on my note 4. I have 2 weeks to return it to o2 if its faulty or is it just a phone with bad wifi in general?
Edit: i think the facebook thing might be a facebook issue as its happening on my note 4 too but everything else is specific to my a5.
