[Q] Acer Iconia A500 on 3.2.1 - Wifi problem - Acer Iconia A500

Hi...
I had been using my tab for over 4 months without any issues. My wifi has suddenly stopped working (tab gets connected to the wifi but the the icon doesn't turn blue and the network is not up). I had recently updated to 3.2.1 but it was working fine for a few weeks on that too.
I changed my Wifi router security from WEP to WPA and also tried using static IP. I even did a factory reset (apart from the hard and soft resets) and I still have the problem. It is not rooted (and I don't want to do that yet) and since I'm not able to connect to the internet, I can't use any market apps to fix the wifi issue (even if there is one). Appreciate some help on this. Thanks.

This was happening to me all the time pre 3.2.1. Updated, sometimes it still happens but a lot less. I don't have my tab in front of me but I did find a Wifi widget icon. All you do is press it once to turn Wifi off and then again to start it again. You can probably find an APK on Google and install through your computer.

Kjy posted a wifi fix over in his rom. Install it. It was Acer official so I know it will work with stock. Having a similar problem and thinking about installing myself.

Yea but don't you have to be rooted to install that which the OP said he didn't want to do.
I am having wifi signal strength issue with mine as well. I think I am going to sell mine to get something else. It seems like these units are notorious for lie signal strength which sort of defeats the purpose of a tablet. When my phone gets significantly better strength that is bad.
I think it might be because of the metal back cover and a poor antenna.

Should I just go into recovery mode and install the specific file? Can you point me to the location of the fix?
Thanks.

Search this forum for the file... It's not hard to find. You'll need ClockworkMod to install it. Just flash on top of your rom, reset cache and (just to be sure) dalvik cache under advanced...
That actually only solves a part of the problem; the other part is the fairly weak antenna (just replace it, instructions are in this forum). The less intrusive solution is a repeater (~30 euro here in Germany).
Another good lead is to use a better WiFi AP. Cheap ones (particularly with those 10dbm antennas) tend to produce a lot of noise, which in turn triggers the driver bug (which seems to be the root of this evil) more often... this can be so bad it actually makes WiFi completely unusable (happened to me). The only solution to this is to spend a few extra bucks for some good router hardware (I use a Linksys/Cisco router and Huawei repeaters, all of which work fine).

Legend wifi issues

Hi,
I am wondering if anybody has similar problems with wifi - 3g/data connection works perfectly, but when I am connected over wifi, after sometime the connection dies and I have to disable wifi and enable it again, in order to restore network access. I hoped that froyo would fix that, but as there is no froyo on the horizon I decided to ask.
The phone firmware is 2.1 update1
Software number 2.05.405.2
Sent from my HTC Legend using XDA App
Yes I get this too. The connection is still active but many apps suddenly decide to notify me that I need a WiFi/3G connection before I can use them. Turning WiFi off and back on fixes it. This also happens on my branded Desire running 2.1, which may imply it is related to the router settings. I will have to test on other routers. My WLAN is configured to 802.11g only, WPA2-PSK only (WPA-PSK and 802.11b not allowed) on channel 13.
actually great to know that i'm not the only one. i get this all the time, and i even emailed htc about this and response was retarded. they told me how to connect to my router. i tried pretty much everything on this issue. connect and reconnect, change channel from 13 to 11 or 14, nothing seems to be working. hopefully 2.2 will change all this.

i think the htc legend has the worst wifi reception for all phones of 300 $
havent noticed a single improvement with every update
I had this problem with my first legend. The touch screen malfunctioned so I brought it back and got a replacement. The new one is much better. I am very happy with it.
For instance, in my home office I could never connect with my first legend, it would say association failed when trying to associate with the AP. On my new one it works and I've had it sitting on the desk now for about 4 hours and I picked it up and unlocked it and the wifi worked immediately.
I very occasionally had this until I switched the wifi sleep policy to never after reading somewhere that it would actually increase battery life and haven't had this problem since. Not noticed any difference with battery life though I only switch wifi on when I need it and off when I'm finished.

For what it's worth, I have the same problem and I'm sure it's related to my phone, not the routers.
I hade no problems with this before my last OTA update...

i dont want to hijack the thread but is the wifi antenna like **** for everyone or is just me?
im thinking that it might be the aluminium case that shield the antenna because reception is unbeliavable bad
im curious to know if desire/nexus mount the same wifi antenna as legend
if you put static ip it works perferct for me

I only have a problem very occasionally with wifi, maybe once per month, and I think this has more to do with my crappy router than anything else.
I have the same problem with WiFi cutting out afters while even when the phone hasn't been moved and when its situated inches from the router
Sent from my HTC Legend using XDA App
Generally it is not good idea to have router and client too close together. That way radio noise increases and that's not good.
Thanks for the tip. but it does it downstairs too when Im watching TV the phone is well away from all electrical appliances, after toggling wifi bOFF/ON I get full signal strength.
Same here. After a few minutes normal browsing on Wifi, pages seem get so far then refuse to load. Only solution is to turn WiFi off then re-connect. The WiFi permission is set to never sleep. I'm not rooted and running stock wwe 2.3 ruu.

Anybody have any ideas how to resolve this issue? It's really frustrating having to re-connect wifi every 5 mins. Possibly to do with debranding to stock wwe 2.3 ruu from Vodafone?

[Q] wifi problem solved?

hello there,
this phone is just released in my country. i would like to buy it but i found this video on youtube: http://www.youtube.com/watch?v=ptg6cLdA9OU
is this problem common? is there any software to fix?
this video is too old (the rom is B133), i used both B135 and B136 now, with no Wifi probs at all
that's great. thank you.
I agree. I am also on B136 and no issues at all with wi-fi. Good Luck. I think it is a great phone especially for the price.
B136 is the pre installed ROM?
Or in other words: people that buy the Ideos X5 today will not have any wifi connection problems?
Obviously I can only speak from my experience with my own phone, but it came (3 months ago) preinstalled with B133 and did an update over wifi in the phone's update options and had no problems before or after the update. The update was about 3 weeks ago for me and I have been using the wifi almost every night since I go the phone. I am very happy with it
Can warmly recommend this phone, its great !
The price is nice, the quality is fine and the phone is getting a larger community !
If you find trouble with old firmware always update to the newer ones !
Grab them at Huawei and upgrade your firmware, they have a guide included on each firmware download pack you download.
Agree without doubt. I never experienced wifi connection problem. But only some education institute use PEAP encryption may post a problem with most Android, though not the phone itself .
Sent from my IDEOS X5
unfortunately its the phone thats causing wifi dropouts in my case..
i can connect to my wifi router with my iPhone 3GS, my notebook, my netbook, my NDS, etc.. in fact X5 is the first and only device that has connection problem with my wifi router..
though i like this phone very much, i can honestly say that wifi problem does exist, at least in certain instances including mine..
So it has been established that this phone sometimes has wifi issues. The question is; can they be solved? and how? anyone got any experience in that area?
I'm on B136 and WiFi is still broken. B136 seems to have made Wifi connections a little bit more reliable, but it still drops out pretty regularly, usually when I try to update more than one app at a time from the Market. In the middle of the downloads it stops because the WiFi has become disabled and has to be restarted again.
It's less of a problem when there's only one update to download, but if there's two or more it happens quite frequently. It also still sometimes happens (though perhaps less frequently than before B136 was released) while it's not downloading anything, just sleeping (I have it set to not disconnect when asleep) or awake and connected to my WiFi network.
The unreliable WiFi connections are one of the two worst problems with this phone (the other one is the wildly variable battery life).
Nobody has a definate solution to this problem?
Is it part of your insurance btw? it is clearly malfunctioning and perhaps should be fixed by the company you bought it from...
i am using genokolar's b137 and wifi is fine ( i had problems before with stock 135).

i have removed some apps he put in there (like nofrills[something like set cpu], a chinese market etc) to make it a total stock rom. just be sure the 1st app you install is Superuser.
I did some tuning to my wifi configuration file and that's all I did to solve connection problems. Just take a look through my thread in the general section with subject title "Wifi Client Tuning ... Solve Connection Problem "

Wifi connected but doesnt work.

We have 3 SGS2 at home and a Billion 7800N modem
There is a recurring problem on my wifes phone where there is no dataflow. I cant even reach the modem. It will just start working all the sudden for a short period then stop again.
Things I have tried.
1. Using it right next to the router
2. have tried using different channel
3. have reset modem
4. made sure sleep policy is on never
5. Update firmware and hard reset phone - no new apps installed - worked at first but now having problems again.
It never loses wifi connectivity....internet just does not work. Turn 3g on...works fine.
What could be the problem?
Only things I can think of
1. Faulty phone
2. Virus? That phone is sometimes used to check out Chinese websites...and I know some of them can be dodgy. I forgot to ask her not to go to any of those sites after the hard reset as trial and error.
3. Not certain but this problem may only started when we updated to 2.3.4.
If need be Ill hard reset AGAIN when XXKG6 is out - I dont want to flash back to 2.3.3 to try

I have the impression, that the Broadcom WiFi drivers of Android are still buggy, because my Asus Transformer's WiFi also isn't very good.
When using a static IP address and setting Google's free DNS 8.8.8.8 as a secondary DNS server (the router as primary), my SGS2's WiFi works best.
Maybe give it a try.
I have the exact setup and tried all the things you mentioned to no avail. It works sporadically after I reset the phone wifi on and off but it won't maintain data connection for long. Although the signal indicator says it is still connected. the billion 7800 works on my wifes sgs and connects without problem to my work htc legend.

If you google for "galaxy s2 wifi no internet", you'll find out, that several SGS2 owners have exactly the same problem.
I all cases it seems to be the router's firmware, that causes this problem. I found two users reporting, that the only solution was to download a new firmware from ...
http://dd-wrt.com
But maybe it helps to drop the speed from 802.11 N to G?
I have the exact same problem and my firmwire on my router is the latest. What I do to fix this problem is just unplug my router and plug it back in. I find that fixes it for me. Post back if that doesn't work

That's why two guys reported, that they had to download a new FW from DD-WRT, which solved the problem for them.
Sorry, that I don't post links ... it were german forums.
I have the exact same problem. You say that the other two S2's work perfectly? If that's the case then it must be a hardware fault. I'm gonna take mine to be fixed or replaced.

Likely ... maybe different firmware?
Yes....my SGS2 and my brothers work fine. When I update....I update all 3 so we are all using the same firmware.
Thats why I believe its a problem specific to 1 phone....not the router (although I did update my router to latest firmware just in case.....same problem)
As a side note - my brother has a microphone echo problem when using a specific gel case. When my wife and I use the exact same case - no problem. I dont know how Samsung build their phones - but its not very consistent.

That's why we have a thread about the "Made in ..."
But that's not only a Samsung problem ... I know that from the Asus Transformer forum.
Ill see where our phones are made if I have time. If anything though, my brother should be the odd 1 out as his was bought in Australia whereas I got the other 2 from UK.
Ill get to the bottom of this....even if I have to keep doing hard reset and trial and error tests. Not being able to use wifi is a huge deal.
Just to confirm, the problem's not only apparent in 2.3.4. My phone has the same problem with 2.3.3. I've sent my phone in for repair now so i'll post my findings here in a week or so. Have you got any further with it?
I sure hope they do fix it somehow....It's becoming increasingly annoying having to flick wifi on and off, downloading apps is the worst. This never happened on mine or my girlfriends htc's.
Anyone able to find a solution for this problem? Just picked up my Galaxy S2 and have the exact same issue Wifi connects, surf the net for about 10 sec, then nothing.. still connected to Wifi and everything.
At work at the moment so can't really play around with the router settings but will try once I get home. Have been looking forward to getting this phone for a while now and to have Wifi issues right off the bat is quite disappointing..
wifi connected no data flow
i had the same problem
i tried different ways no sucess
i tried Set DNS Pro from market
tried different settings
applied different dns
shift from open , custom to google ang keep checking the internet in browser
after few try it works everytime
its to do with assigning ip address in android
thanks
I posted a solution a few weeks back....but i think most people overlooked it....so the solution is
Go to settings>>>>wireless and networks>>>>>wifi settings>>>>hit menu and go to advanced>>>>regulatory domain>>>>change the channel to 14.....thts it....it worked for me on vibrant,nexus one and even on sgs2..hope this helps

Channel 14 is not allowed in most countries ... my german router e.g. doesn't have channel 14, only 1-13.
I had similar issues with my Asus Transformer and found out, that a static IP works best, BUT only if a secondary DNS is assigned too. I used Google's 8.8.8.8
Give it a try. The Broadcom drivers seem to have a bug, when no secondary DNS is assigned.
The "regulatory domain" setting isn't there on my galaxy s2 ;/ Will give the static IP solution a try.

Is possible to have this WiFi issue?

Hi!
Well, I have a very weird issue with custom ROMs and WiFi.
The history begins last sunday. I was using GingerDX wich is really great, but I had some problems with it, the most important was not being able to install apps in my SD card.
So, I switched to GingerXperia V22, this is a cool ROM too but I really don't like that my music lags when I turn my screen on. Also, the SE default dialer and Infinity view are bad and slow, but I didn't have the problem with WiFi, until I switched to XGin 6.2
Everything worked OK except for this:
El Brillantinas said:
I just realized a terrible and very weird error with this ROM:
I couldn't connect to The WiFi of my mate's office (where Im currently working). But the weirdest thing was the modem worked fine before trying to connect with my Xperia, but after turning the WiFi on, the modem just got busted and didn't work anymore!! So, no internet in the office computers, neither in my iPod, in my mate's smartphone, etc.! It was necessary to turn the modem off and then turning it on, and turning my X8's wifi off to make the modem working properly again.
Weird, huh?
I reflashed, and the error happened again.
So, I flashed back to the ROM I was using before (GingerXperia V22), and now the WiFi is working fine!
Anyone else with that same error or Im the only crazy around here?
Click to expand...
Click to collapse
I tried kuyaDROID and the same error happened.
I also did a full wipe... And nothing, the WiFi error remains on those two ROMs. So, Im currently using GingerXperia.
So, the question is: Is this really possible? And, is there any solution?
There may be some bug that's overloading it. Also was it the modem or the router? Cuz if it's wifi I would guess its the router but you said modem? I'd just use a different rom that works.

Guess is the router, where the wired networks are connected, it also gives the wireless signal.
As I said, Im sticking with GingerXperia, wich is not causing the error and Im connecting to WiFi with no problems. But I have personal problems with infinity view, SE's dialer and music lagging.
If is about a overloading bug, how could I fix it?
Im using stock kernel, btw.
To tell you the truth, I'm not actually that smart in this, but by overloading I meant that it might be trying to use too much data or something along that line, did it work fine over 3g?
Sent from my LG-VM670 using XDA App
Yeah, I didn't have any problems with 3G.
Don't really have any idea then, I've had problems with mange one device at a time but not fully crashing. Last advice would be that maybe the router has a limit to the number of connected devices it can have and your phone puts it over, try disconnecting one device then connect your phone

To further assist you may I ask some questions;
1. What kernel are you using?
2. Have you tried connecting in other Access Point aside from the previous AP you are connecting with?
3. If using custom kernel did you delete all the modules in system/lib/modules?

1. Im in stock kernel.
2. Nope, I didn't try it. I don't have internet in home, but I'd try in my girl's house.
3. same answer than 1.
Thanks for being interested in this curious case.
If your using stock kernel then you shouldn't have to encounter those issues as most roms esp kuyadroid as you mentioned earlier is made for stock rom. I suggest trying into public wifi access and see if you could be able to connect. You have to have two or more access point to test with as router might have different configs than your girls setup.

Wifi Signal Strength Issues

I've been looking everywhere for solutions to the weak Wifi on the Nexus 10, but didn't find any solutions yet.
The network also has an added wifi repeated connected via LAN, but still the Nexus keeps 1-3 bars of wifi.
I have another 5 or so Wifi devices, Galaxy S2, Lumia 920, iPhone, 2 laptops. None of these have any issues and are always on 4-5 bars, usually max all the time.
I've tested both on 2.4ghz and 5ghz, both to my Asus AC66U and also to an old RT-10, one Huawei, etc.
It's very clear that no matter the band or router settings, the Nexus 10 really has a weak signal reception in comparison.
Since the Nexus is new for me, it's on 4.3 and I don't know how it performed earlier.
Are there any other modem drivers or similar that can be flashed?
Any other experiences with custom ROM's?
Wifi strength has been a little weak since release honestly. Has been mentioned alot here and around the web for a while.
Now my problem since the latest update has been wifi drops where I lose wifi transfer completely even though the wifi icon shows a good connection.
I think this is something new (i know it is for me at least) and have been looking to see if anyone else has seen this issue in the latest software release.
If I toggle wifi off/on it works after but it is a huge pita.

This problem (wifi icon gray and no internet connection) started with 4.3 for me without question. Previously wifi connectivity was rock solid and I never gave a second thought to it. Nothing changed but the android version. I hope it is fixed in 4.4.

mine was doing the same thing. i tried clearing the cache, uninstalling apps that i thought might interfere and then a full factory reset. still had the same problem. i rooted and then did a factory reset from recovery and it hung up reinstalling apps so i did another factory reset still in and out. i did another factory reset and logged into my wifi and left for a few hours to work on something else. when i got back the signal showed full and about half of the apps installed. i reinstalled all of the apps that hadn't installed and it's working fine now. not sure why i had to wipe it 4 times but it's working fine now and streaming movies without a hiccup. i guess something kept getting corrupted during the setup or reinstall of apps. anyway it's been working fine for a few hours which is the best it's done in the last month.
