Help : 6815 wifi gone

Hi there.I've been using my 6815 for over a year now and was enjoying it till something happened to the wifi.I've used dozens of different firmwares on my phone and not once have this kind of problem before.Basically my wifi is not usable in any of the firmwares for sometime now.I2ve tried original 5.0 than 6.0 several 6.1 s and several 6.5s.I cant even enable wifi in any of the firmwares.For example right now I am using a clean 6.5 rom, and in Hp Asset Viewer it says for wifi :
driver rev:N/A
firmware rev:n/A
Hardware rev:1.0
ip address : n/a
mac adress : n/a
radio preset : yes
In some custom firmwares there are different wireless connection managers and I cant enable wifi in any these managers too.I tried changing things in registiry as suggested to someone like me but it didnt make a difference either.
so... Any suggestions ?
I have problem like this with wi-fi. Can anybody tell us a solution?
wifi module gone, its faulty on board, no solution. happens on atom series.
atom manufacturer quanta uses cheap conponent to build this device.
common fault on atom/hp68xx series
lcd-cannot see by side view, lcd will appear jumping under sunlight, newton ring appear easily
earpiece jack-on board, always get faulty when user plugin and unplug from it, device will think earpiece is still ard and do not project sound out from normal front speaker.
usb-detach from board easily when user drop the device while charging.
wifi-wifi cannot be on, system thinks wifi module is not ready or unavailable.

Desire X and Router

So i bought this cell..i already was kind of disappointed..now i really hate it..
It gives me problem with the router..like reset it...or make the wifi get stucked...
It's ok as long as anything connect to the wifi uses internet...but whenever i need to use the lan,,,after a while the router shuts everything out...
There is any solutions...other than change router (i tried every possible configuration, even with no protection at all, fixed ips, only g..)
I don't know what else to try...
I never thought a cell could ever mess up with the router...

Well, an android phone can't mess up a router so the problem is the router itself. So changing the router is the only solution

Well, since that router worked perfectly until now guess the problem isn't only the router... My desire works, without making me have any problem wiith the lan..

I don't think any phone can mess up the router. It has to be the problem with your router.

He can't, stop blaiming the phone. Maybe your router needs an update or you need a better one.

If you don't believe us, why did you asked for help in the first place? A phone can't mess up a router, only the router itself or a PC can
ok..i have a belking n1 vision...and to get a "better one" i should get one with nothing but stupid leds? cause of the cell??

It's the router...great..i paid it almost as much as that cell...

Try updating your router firmware. If that doesn't help, try a different firmware like tomato or open-wrt.
And please report back.

wifi issue

Anyone notice that the xa ultra has some wifi connection issues? For example I'm connected fine and everything and I leave my house and come back.. then it doesn't seem to pick up my home's wifi. I have to restart the phone then it comes back. Anyone else notice this?

Only with router upvel ur315bn. Other WIFIes is okay.
Never had that problem.
Sent from my Xperia XA Ultra
Every. Single. Day. I leave my house and the wifi won't reconnect at school, or home. I restart my phone and it connects just fine. When I'm at school it won't connect until I restart, and then it connects there fine as well. It would be interesting to see what variables between locations has cause/effect on the connection. I'll do some analysis when I have time, see if there is a time variable associated, like if it happens right away or takes time for the problem to occur. I have a feeling it's related to the cheap parts that Sony used, not sure what wifi chip is installed.
yeah I haven't had this issue yet either. Have an apple airport router. I have only had the phone a week but no problems.
OK it just now happened, (wifi won't connect) and I realized it was just connected when I was inside a building at school without cell reception. I put the phone into airplane mode, then turned on wifi, and sure enough the wifi connected. I'm thinking interference or lack of power is preventing wifi when a medium strength LTE signal is connected. I'll keep testing scenarios that fit this theory.
Just a quick update. It seems putting the phone in airplane mode, then manually turning on wifi only, the wifi connects immediately. Turn airplane mode off, wifi stays connected. No need to restart. Wifi drops on me several times a day and this is my fix. This fix did not work 1 time out of the past 20, and I had to restart.
Mine has been doing the same thing.... ugh Sony can't get their crap right no matter what they do. Dear God.
Anyone else having issues with auto brightness not working properly as well?

I'm having the same issues even with the latest firmware updates. I tried contacting Sony support and that was a complete waste of time. Anyone have any suggestions?

No problem here on the normal xa mine is a F3111 LTE model WiFi works and connects great on all Firmwares. Have you tried the software repair option via Xperia companion? If it's still the same after this, you need to take a log using the built in logging application and send the logs via Sony support forum it gives you instructions on how to do it in settings think one of the guys names is Richard, about phone, diagnostics, advanced logging they've actually been pretty good regarding any bugs and fix them once they have some logs to work from.

Thanks for the reply and suggestion. Unfortunately, the repair option didn't solve the issue. After Googling it, it appears many users with the 3213 model are having the same issues. Ugh.
I did not know about the "diagnostics" feature. I enabled it and then it auto uploaded and then turned off. So does support email you or Richard gentleman contact me via the phone somehow to give feedback?
Thanks!

As far as I know it's all done through a pm(message) through the Sony support forum. Then they pass it on to the software peep's and then wait for the fix it may take more than one person to provide the logs before they sanction the update unless they find a bigger problem.

Xa ultra wifi
Here's a funny thing, as long as I am not connected to Bluetooth, WiFi works flawlessly, weird.....
I'm just going to assume we have no fix for this yet? the whole resetting my phone is getting really tiring. blah I wish Sony would fix this or at least acknowledge it
I have the same problem with my XA. I've only had the phone a few days and I'm always having to switch it off and back on. SOOOOO annoying. The guy that sold it me said I could just return it. I'm not buying Sony ever again!!!!!
Been having to use my 4g at home alot of the time, which is eating up my data something rotten. It shows the WiFi is on and has full signal, but it's often so slow or even worse dead! I've honestly had 2g on a crap old phone work faster than WiFi at times. I have just "forgotten" all saved WiFi networks and signed into my home WiFi from scratch and put the password in again. Seems to have done the trick, but I'm not holding my breath that it's gonna last.
I'm curious, it might be insignificant, but just wondering what WiFi service providers all of us with problems have? I have BT infinity. For a while I thought that maybe it was just BT being rubbish. But my partner has a Samsung galaxy s8+ and she doesn't seem to have any issues. I've used the WiFi on my linx tablet, no issues. The Xbox one doesn't really lag either.
So it's either that this phone does not like BT or its just my phone being pants!!! Doing my head in, I have to keep getting my partner to send me extra data.
It's seriously getting on my nerves now

This is my first Sony Android phone, and I'm not touching one ever again.. What's worse for me is that mine is still on Sept 2016 update and my carrier locked the bootloader so I couldn't update it myself, as my network don't even care if I have the latest security updates or not

rk3188 wifi, 3g issues

Hi! I bought HU for my bmw e46 and unfortunately my excitement about it soured a bit, when I realised that my wifi wouldn't turn on at all... I wasn't worried that much because I was gonna use 3g huawei modem anyway to have independent internet for the unit. Unfortunately it doesn't work either, because by instructions you need to turn wifi on as well... I had impression that it was software issue and tried looking for solution. I came across PPP widget, but as there is no way to get connection I cannot access play store and install through apk doesn't work. I then decided to give it malaysk rom with hope that this would solve my Issue, but it didn't. Its all the same. This must be a hardware issue with wifi adapter by my assumptions, but why dongle is not working when it has nothing to do with wifi? Does anyone know how to get 3g working? I just want my 3g and I dont think I'll need wifi that much. Also does anyone have stock 5.1.1 rom for eonon? I tried backing up, but it went wrong and I cannot reverse it in case Id need to send it back. Thanks for help in advance!

Issue #1: wifi (& BT?) not working anymore.

Moto Z has never had a "fantastic" wifi connectivity (with some issues with dhcp too, see my thread about it...), but anyway it worked... since some weeks ago!
Then, without any change in sw (I'm still on MM, rooted and with Xposed), it begins to be unable to connect to quite any 2.4 GHz wifi available (5 GHz connectivity seems to be unaffected) :crying:
It finds networks, then, if I ask to connect them (even on open and not encrypted and not mac filtered wifi networks) it will try to connect for a second, then it returns to "saved" state. After some trying it goes in "error connecting network" status.
Obviously ALL my other android devices connect fine in same conditions and even my Moto Z connected fine before the issue came out.
Only in isolated places with a SINGLE wifi SOMETIMES is able to connect... but I am talking of distances of 2-3 meters from router, not more....
I've already tried to "forget" all networks, to restore wifi defaults, to clear cache & dalvik and tried some "wifi repairing apps" too, with no results. On Lenovo forum I saw some had the same issue and even a factory reset didn'the solve for them.
I think even BT is having same issue, but I'm not sure... (I don't use it a lot....).
Any idea? Others with same issue?
@erfanoabdi no idea about this?
I also Have the same problem. and my request to Lenovo please solve this issue as soon as possible.

I begin to think that it's a hardware issue, since even bluetooth seems to be affected as well.
Weird is that networks are anyway detected and with regular dB levels too...
One user on Lenovo forum reported that this began for him when he had the memory of the phone full over 90% and for me it has about been the same bit I think this could be only a coincidence...

Hi, i had this problem too and I think its definitely a hardware issue. I think Lenovo just has some quality assurance issues in the production and you and i just had the luck of getting a defective unit.
I'm really happy that i still had warranty when that happened. The main board on mine was switched, so i guess its not even an wifi/bluetooth antenna issue.

But what channel are you on? From what I've gathered it's only retapac right now.
No more having this?
Mine (just before been destroyed by assistance center trying to change battery... ) had begun to not be able to connect (if not sometimes...) on 5 GHz networks too... it definitely seems an hardware issue...
i have the same problem, no wifi and bluetooth. Anybody tried flashing modem?
Losing connection happens mostly when connected to 5GHz, can't find a way to force connection to 2.4GHz.
