it could be.. or could also be software.. have you got any battery management apps or task killers set to auto?

No, I don't have any battery management apps or task killers set to auto. How can I find out if its software or hardware?

well for me when i had the rogers firmware, wifi worked without any issues, whenever i flashed the hong kong firmware, it started to cause problems, so im sure its software related

Are you away from the router? I think WiFi turning off because you're too far away from router is common (at least for me).

if you've not unlocked your bootloader then I would recommend a repair via SEUS or PCC.. bit of a pain to set everything up again, but worth it if it solves your problem.

any solution to this problem? I can only stay on wifi for a minute or two then it keeps on disconnecting even though the indicator at the top says im connected. No issues with 3G it is just the wifi that disconnects. I've tried sitting real close to an AP but it doesn't help.

Have you upgraded to 2.3.3?
This supposedly fixes the issue.
I had minimal problems on 2.3.2 when I first bought the Arc but have had none since the upgrade.

I have not yet, I will asap. I guess that should have been my first solution. Been busy at work the past week.
But also I have read some other threads that was not the solution. Anyone else experience this?

I had the same problem, sent it back to vodafone who flashed it to 2.3.3, did not help one bit. I've sent the phone off to sony ericsson now, hopefully they can sort something out.

Wifi disconnection problem fixed with 2.3.3 update?

Can anyone confirm if wifi disconnection problem has been fixed with the 2.3.3 update? Thanks

Well I flashed 2.3.3 2 days after I got my Arc, and I've never faced the wifi problem, guess it is fixed?
(Do you mean the one where it disconnects while downloading large files? Mine still gets disconnected about once in 2 days)

Its the one when arc keeps dropping the wifi connection. When wifi sleep policy set to 'never' and yet it drops it almost every time the home button is pressed after the screen has gone off.

Exactly that problem I am still having with my 2.3.3 arc

Mine is better

After upgrading to 2.3.3 it did not seem to improve at all for me, still randomly drops the connection, despite the wifi icon in the status bar still showing as connected. I returned the phone to vodafone yesterday who denied any knowledge of the problem despite so many people on the net complaining about it. They've sent it back for repair now anyway, fingerscrossed they sort something out, but i'm not too optimistic to be honest.

Still have wifi problem here after 2.3.3. Hope they'll fix it's soon

Seemed my router was indeed the problem (Dlink DIR-655).
The time the router ran in was somewhere in 2004, so maybe that caused the Arc to not be connected properly. Weird that laptops and the X10 mini we have don't had any problems with it.

@Roel_1982
what did you do to your router to fix your problem?
Did you change some settings?
Or did you get a new router?

There is no wifi disconnection problem with the Arc. I can confirm this because I use my device mainly through wifi when I listen for hours to online radio stations and haven't faced a single disconnection problem.

yup, still drop out ... GB 2.3.3 hk .145 firmware, TP-Link modem router.
Change wireless router to "g" mode and works ok. It seems to have problem with "N"

I adjusted the time, to update automatic.... also gave my Arc a fixed address through DHCP.
Ever since no problems with the connection. Maybe you could see if there are firmware updates for you're router available.
Update: got the problem again 2.3.3... screen went off, came back on... wifi seems to be connected in the status bar, but it's not

test this http://www.google.com/url?sa=t&sour...PrRWuDqnnVcDpBYIA&sig2=uxmWpCo5pLQ9vBzEpDEqzQ
it may help

Still have the same problem after 2.3.3 on Xperia Neo. =(

Try to turn off WMM in the QoS section of your router. It worked perfect for me. No more drops or disconnections. It's because of poor implementation of WMM in Xperia WLAN driver.

i just flashed the firmware using SEUS, and i dont have wifi disconnections anymore, i think its something to do with flashing the firmware via flashtool o rosmething

I just flashed the firmware using flashtool and i dont have wifi disconnections anymore

My Arc never had a problem with wifi and it doesn't on 2.3.3 either

Something that has worked for a few of us is switching the router to just wpa.

[Q]Could the wifi router be the culprit?

I have previously posted on how my WiFi was only working via a ****ty app.
Now I have some more info that makes me beleive that our home wifi router is the cause of that.
I went to my friends house and WiFi worked completely normal there, so it must be the routers fault right?
I have also reflashed the radio, so it probably isn't it's fault.
It all started happening when I updated to the OTA 2.2
Any help on how to fix this?

what about flashing a custom rom?

Well, I'm running CM7 with 2.3 and it's still the same :/

I don't have pc wifi to experiment with. But I will try to tell something.
Wifi on wildfire has the support of b and g networks by default. So no wifi "n" network on wildfire by default. There is a chance of difference in these network types between ur wifi and ur friends wifi, such that it works only with ur friends one.
And I think I saw somewhere in development section that someone made wifi "n" network working on wildfire. But Im not curious about it since I don't use it.

But what's really odd, is that it worked like it should on stock 2.1, so obviously 2.2 ****ed something up...right?

Xperia Arc S wifi has weak signal

Hello,
I have bought Xperia Arc S(running 4.0.4 now) few days ago, and ran into some wi-fi issues.
It's not the connect->disconnect->connect issue, that one is fixed thanks to one app (FXR WiFi fix and rescue), but there is another problem.
The wi-fi signal is just too weak. its like I have to be 3 m from router to get full signal, that's ridiculous.
At place where pretty much everyone other I know has decent wifi signal for me its off already.
It was same with Gingerbread, maybe with marginal difference only.
This is very big annoyance for me and limits the main purpose i bought new phone for - being able to browse net and check some things when i need to.
so, is there any way to make the signal stronger?
also, as i'm aware this is most likely hardware issue, would requesting replacement help it?
EDIT: also, it's not router issue, I've tested it on three routers

If your baseband is on .56 then update to .72 or .77 (or higher) because baseband is sometimes the issue.

Repair
Use sony update service to repair the phone.
Check if it works or update the BaseBand (72 or 77)(uncheck wipe user data) using Flash tool.
Check whether the baseband is compatible or not with your mobile before updating. (search in the forum for baseband and read the posts)
Hit "Thanks" if anyone helped you. :good:
Xperia Arc LT15i
Rooted/BootLoader Unlocked
Running JellyBean - FXP137/CM10

EDIT: ok, so turns out i have .77 already, so repairing phone is my best bet?

did the reset, i see no improvement.
it seemed to be a bar higher than usual, but then it dropped back down.

U wont see any improvement 'cause this is a problem without a solution. Arc S has a weak wifi, regardless the android or the baseband version. I'm currently on .587 firmware with .77 baseband and the problem persists. I tend to believe it's hardware related issue and I've learned to live with it, but dammit!, even my Archos tablet has excellent wifi signal..
Sent from my LT18i using Tapatalk 2

so its general, every single arc /s has it weak like that, not just unlucky units or something? well that's sad how small amount of quality they did put into their flagship...

my wifi is also weak I have 77 baseband.

I think that it's a software problem, not an hw problem: before I upgraded to Android 4 it worked perfectly. Now it requires at least 70db of wireless signal, otherwise it continues to say "Autentication problem".
Hope next upgrade will solve it!

Try this :- Go into settings > more (or maybe it's xperia on stock rom I can't remember, but navigate to>wifi networks and change it to GSM only.
Then download a wifi scanner from PStore and run it. Follow it's instructions and it will detect the strongest channel to you.
If you are just wanting to use it at home through your router, do the scan and it will recommend the strongest signal channel for your phone, then simply change the channel setting on your phone / router to the recommendation the wifi scanner gives you.Your downloads uploads should now be better.

I think that it's a hardware problem. When i had GB, my signal was very low while on samsung y (5369 entry level) it was signal very good. I know that signal is more low with ics but it's hardware low quality. unfortunately some components (wifi and camera) are low quality on the our device.

[Q] Why does JB 4.1.2 not connect to wifi properly??

Hello all. I have been playing with the new 4.1.2 JB ROMs on my 7100 Note2 and have been having one major and repeatable issue, that I have seen mentioned a few times by others, with no obvious resolution.
I have tried the various leaks of the 4.1.2 that were floating around (the stock one, Wannam and Android Revolution HD 5) and now I have just tried the final Polish PLAY version of 4.1.2 as well as the latest Wannam as well. All do/did the same thing:
They can see my wifi SSID and they can BEGIN to connect and "obtaining IP address" comes up. EITHER they then fail and tell me connection is poor and to try again, or they will connect and then drop within a minute. Just today I made some kind of movement on this by trying different kernels. Perseus25 gives up and tells me signal is poor. Perseus27 WILL actually connect and stay connected but can never actually surf anywhere. Note2Core will either connect or tell me my authentication is wrong (which it isn't) and when connected, it too refuses to surf. RedPill is same as Note2Core. BTW, even when they DO connect, they do so at a measly 5Mbps (and cant find internet)
Now, you are all probably thinking "his wifi is rubbish!" but I REALLY cant see how that can be! Firstly, there are other users out there who have mentioned this in a few threads but I have never seen any useful replies as to a solution (or a cause!). But also, if I restore back to my usual ROM which is Android Revolution 4.1 HD (=JB 4.1.1) with a perseus25 kernel, then I connect immediately and stable at 54Mbps and works great. (all it takes is a CWM restore back and it is working 100%. same location in my office, same router, wifi etc!) Plus same wifi serves two laptops, wife's Galaxy S2, and has seen many iphones, ipads, and other laptops all fine.
Back in the days of the leaked 4.1.2 I DID try jumping wifi channels on the router just to prove a point. Every single one did same thing.
Flashing procedures have been the 'standard' method: boot into CWM, wipe data/cache/dalvik/battery, then flash new ROM, boot OK.
I had assumed that the early leaked version of the ROM had some bug but very disappointed to find same behavior in the Polish PLAY version which is final release AFAIK. It makes all these subsequent ROMs based on it totally useless to me.
I even extracted and flashed the modem.bin from my working ARHD4.1 ROM but nothing changed. So modem and kernel same as working systems but something clearly broken somewhere.
If you are one of the other folks out there who also has this issue, might be helpful if you give some info about your setup, so somebody clever out there can help us join the 4.1.2 club?!
Any thoughts?
(setup: UK VirginMedia 120Mbps down/10Mbps up. Cisco Linksys E4200 router. about 10 feet from router with one 'paper wall' between! ARHD4.1 finds full signal and surfs fast. 4.1.2 totally unusable)
Help me Obi-Wan Kenobi(s), you are my only hope!

I have noticed similar problems on my SGH-i317 using CleanROM 3 (4.1.2). The wireless connection randomly drops while browsing. This happens even in areas with excellent signal quality.

Thanks for contributing. Helps prove the point that it is something in the new ROM as our wifis are fully functional otherwise. I have matched the modem and kernel from my working 4.1.1 system and still failing....
I hope we get some help.

I also got this problem from latest WanamLite & Omega ROM. Both are using 4.1.2 JB.
Wifi detected and connected but always obtaining ip address..
Sometimes it tooks so long and can get ip, but still cannot access internet or can't even ping different ip address from the same network.

strange, i've been running omega 7 to 7.4 but dont have any problems with wifi.
i've connected to home wifi (TP-Link), workplace (Cisco/Linksys) and some coffe-shops without any problem.
most of them using WPA2 or WEP. sometimes obtaining ip address with WEP could take a lil longer about (10-15sec) but always a success.
but never used wanamlite for my note2 so cant comment any, srry

I'm not saying the issue is in the wifi itself, but it can probably be fixed by disabling n mode and only using b and g. Also try to make sure the phone gets assigned a static ip.
Issue seems to be 4.1.2 related.

yes.. i'm also facing the same problem.. whenever i flashed custom rom based on 4.12, like wanam 2.0, 2.1 n crash rom, i cant connect to the wifi.. it always shows optaining ip address and it never connected.. now i m using stock rom 4.11 n there is no problem to connect to the wifi..
i juz wonder why it happens to several devices only?

I having the same wifi problem with 4.1.2 firmware...revert back to 4.1.1 wifi connection run flawlessly..strange !

I have tried switching OFF the 5GHz signal from my modem and sticking to 2.4GHz.
Have also tried turned off N and locked it down to just B & G.
Have tried turning off the WMM in the QoS section.
All of these have been mentioned around the place as possible solutions, and I am afraid none of them changed anything at all for me. Also read that one person had his wifi issues resolved when he dropped WPA2 security and went back down to WEP. This is an unacceptable solution to me as I don't want to make my WiFi so insecure, and also, what happens when I go to my friends and family who all (rightly) use WPA2?! So wont even be trying that.
I am actually getting a new Virgin Media Superhub in about 2 weeks so will revisit the issue then to see if 4.1.2 just doesn't like my Cisco router.
Just weird. And frustrating as wanted to move on to 4.1.2!

have you tried changing the channel on your n router?

Ok. I here is my evo 4G lte story. I flashed cm10 as soon as I got this phone a month and bit ago. I totally had wifi connectivity problems at work and at my house. One worked better and one had to be spammed to connect 20 times to connect and would still occasionally drop. I went to sense is from there and found it to be reliable. Though I just moved to the ota, I find this sense to be just as reliable.
In all. The new ota let me move to jb with reliability.

I also have exactly the same problem. I have tried every single 4.1.2 ROM but I can't keep my wifi working. I have had to go back to 4.1.1 as well. My wifi is perfect on 4.1.1. I use Cisco e4200 with ddwrt flashed. Very frustrating!

Try changing channels to below 11 if you're in Europe and the router uses channels above.

I`am on ARHD 6.0 currently and i never had problems with wifi on all the previous ARHD rom`s. Try doing a full wipe or at least also do a system wipe (and wipe cache/dalvik cache, data/factory reset and format preload) before flashing a rom. I`am sure that will help guys.

i have same problem no ip adressing and when i set statique ip no internet
i test Omega wanam mondx... same issue
omega 6.1 works great but at 7 version no internet by wifi, but ok in data
i have a logcat if help (catlog app)
i test rest router, change wpa2 to wpa, change channel, wps, super wipe (allll format) every omega rom, set mac adress in router with static ip
i become crazy why not on all device its n7100 XEF french buy on amazon
