Bluetooth keyboard WiFi dropping issue - Xperia Tablet Z Q&A, Help & Troubleshooting

Hey guys.
I love the tablet z untill today. I have connected a Bluetooth keyboard to the tablet. Every few min or so the WiFi connection drops while Bluetooth and the keyboard are connected. When Bluetooth is switched off there are no drop offs. Any ideas ? I switched off smart connect thinking it may be that?
I am not rooted in anyway (well not yet)

wow this is so disappointing... i've had the tablet for a week and am loving it, but had seen your post and just received my bluetooth keyboard in the mail (a motorola) and sure enough, wifi is like dead when it's connected... i don't think it actually dropped the wifi... it shows i have a signal with my wifi router, but nothing is loading at all...
anyone else noticing this issue?

I noticed this same thing today. I didn't notice this before my update to .370 (Wi-Fi only model); although I don't know if there is actually a correlation.

I am havig the same Issue. Using either a Bluetooth Keyboard, Mouse, or sixaixis Gamepad.
Is this just happening to some (broken) tablets or is everyone having this problem?
If someone is NOT having this issue using Bluetooth and Wifi at the same time, could they please post here, to confirm that this acctually can work properly?
This thread mentions the same problem for the tablet z but no solution either: http://forum.xda-developers.com/showthread.php?t=2339032

Wifi dropping when Prime sleeps

Has anyone experienced the prime loosing wifi connection when the screen goes to sleep. It is not right away but left alone for more than 5 minutes will cause to loose wifi connection. When I wake it, it says it is still connected with a good connection but no internet connection. I have changed the setting to keep wifi on during sleep but it is not.
Suggestions?
lol have you gone into your wifi settings and checked your wifi sleep policy? check settings --> wireless --> wifi and poke around tehre
Yea i did that. I did notice though that when i come out of sleep that my wifi signal in the notification bar is greyed out but still shows that i am connected. Only when it is blue does the internet work. Anyone have an idea.

Thought maybe it was my router. I experience this as well. What is odd is that its a 50/50 shot for if it drops internet or not. It will seem to work fine a couple days, then do exactly as you describe. Figure its software related, joys of being on the bleeding edge
Factory reset yet? That seemed to clear our most minor issues for people...

Yup, right after the ICS update, which did its job in clearing out all other minor issues I had. My dell streak had this same exact behavior, which leads me to believe its a router config issue, not the prime. Planned on messing around with that to see if I could pin down the issue.
Try going into setting- wifi - advanced settings..... you will find your solution there

My solution is not in the wifi settings. Keep wifi connected on during sleep is checked. I am thinking it was something within ics.

Mines done the same thing before ICS and after. My husband's does too and so does my son's OG Transformer. I think it is a router issue though as it never does this at work when I'm connected to wifi there.

Transformer Prime purchased after April 15th looking good

Friends , I got my Transformer prime on April 17 from Office Depot with serial number : C3OKAS##### .
So far no issues with respect to screen freezing , reboots.
I did buy Prime after looking at the previous threads on all the issues , but I couldn't resist the ultimate combination of a Tegra 3 with Android ICS 4.0 . I have installed apps only from Android market and I am using only the stock launcher and yes my prime has not been rooted. My Wifi looks OK no drop outs seen so far. I don't use GPS on my Prime so cant comment on that as of now.
Please let me know if any of you who has purchased Prime( in US) after April 15th has had any issues ? If you are facing issues please post your first six characters of your S/N.
I bought my prime about 3 weeks ago s/n C30KAS****** I have had few problems with it. Screen lockups and maybe one reboot and my Wi-Fi randomly turned off once. Other than those it was been great I love this thing. I am rooted but not unlocked... I want to but I am scared my hardware randomly will go bad after I unlock..
I purhaced mine 2 weeks ago and I have unlocked buutloader, root and custom ROM.
I have never faced any issue, well GPS sucks but I never use it. '
Oh, I faced 1 other issue and thats the keyboard dock... I can see some other have problem with that too. When i connect it to the Prime it wont always allow me to use the keys but only the toggle keys also touchpad wont work, but it fix when i keep reconnect it
Can you tell me your Serial was it C3?

Are you using a different keyboard app?
And beige on a ROM could greatly increase the reasons of why you may have the problem not really a problem of the specific prime itself...I think.
Same serial as OP only problems ive had are a few random reboots that really only occur after using my GPS dongle as well as 2 freeze ups

I also have a C3 serial prime, have had 0 problems with it thus far.
i purchased 1 on march 30, C3OKAS also. after 2 weeks using i had to send it for RMA and havent received it back until now =,=. issues:
-rear camera not working, show only green death
-weak wifi
-gps not working
- screen easy to scratch (after 2 days using i have my first scratch =,=)
- browser is lagging and somehow stop
- got few reboots also
overall, totally disappointed...
My C4 is working well so far. I exchanged a BCO for the C4 late last week....
Stronger wifi (much imo)
Haven't disconnected or lost wifi to neighbor's wifi (before BCO couldn't see wifi)
BT/WIFI streams without loss when prime is in front of me (<2 feet) and during Netflix
BT streams within 15 feet while wifi is connected (mp3)
GPS can find satellites outside within 150 seconds without gps (found 15, use 8 distance 29 feet)
Gps with Dongle very accurate (forgot to write #s down)
So far so good - one point to note: I resisted upgrading to .21 and i am STILL on .15. Battery is not draining as much. I also noticed with previous BCO prime that once I upgrade to .21, my BT would not work past 3 feet while wifi was connected (could not stream mp3). I regard this as the increase in wifi strength seen on some models in .21 firmware update thus interferring with BT.
I will get more concrete nubers with wifi analyzer. Does anyone know of a program that runs onscreen that shows my LINK speed and download speed while running Netflix? I need this to see accurate numbers while running BT+Wifi at link speeds. Thx
Ok from our users we see that still some units out there have these issues. I sometimes wonder is it some kinda malware/virus attacking these tablets when downloading certain apps that takes permission to modify ur programs ?

no problems
C30CAS purchased 7 days ago at Office Depot. I haven't had any problems. Not rooted yet that's why I'm on here.
wifi on 2nd worse
Thankfully, I purchased best buy replacement plan. I exchanged a C1OKA due to poor picture quality. Had poor GPS, nonfunctional wifi direct, but strong wifi. Received a C4OKA, and it seems I will have to take this one back because wifi sucks rotten apples. I am about 12 feet away from my router and wifi analyzer is in yellow most times.

Mine arrived on Friday 18th May with C4OKAS and no BT/WIFI issues. Ive registered for the GPS dongle successfully so it seems they are still acknowledging the problem even though I could get a fix reasonably quickly outside.
Good to see that the new devices have the software issues fixed.
I got my gps extension kit. In 10 days!

C4 Serial from BB
Sadly, after a couple of days of use, I began to notice there is in fact some BT WiFi lag while watching Netflix.
There is a noticeable increase in smoothness when watching with the internal speaker instead of the BT headset. The lag isn't bothersome for casual watching of stuff like sitcoms, but on action movies, it is a little distracting.
Don't know if it bothers me enough to return it. But I have a bad feeling I will be standing in front of a TF300T in Best Buy in the next few days, testing the BT and Wifi.
It is a little sad that a $500 tablet has these problems. Damn is that Samsung had Gorilla glass on it.
Not looking good.
C4, purchased today at best buy, GPS not working.
Am I doing anything wrong? First thing I did was download GPS test, run it, and did not get any locks or views.
Gmaps, on the other hand, does lock on to my location, but doesn't it use wifi connections to triangulate a location?
Does GPS test need to be set up in any way?

Wifi dropping off

I'm having problems with a brand new htc amazing. The Wifi connects but only for a while and only at like 1 bar even if I'm right next to my router. My Ipod and other devices can connect just fine. After connecting it'll remain connected for a while then disconnect. Currently I tried it on stock ics 4.0.3, Energy Rom, and Speedy Rom. Is there anything I can do to fix this? I've also searched at the T mobile forums and I've read some about the wifi driver or something causing this.
Any help would be appreciated.

From other post it usually ends up being the router. Cheap router ? Old, Not up to date with firmware? You should go to stock and call it in to HTC. See what they say. They will ask you for the serial number and software number of your device. You may find the serial number in the ‘Settings’ menu under ‘About Phone’. The software information will be under ‘About Phone’ and then ‘Software Information’.
I'd like to know how this turns out since many others have this problem but no solid solution yet I don't see anybody deal with tech support either.

I have finally found out the real root cause of this it seems it was my iPod interfering with the amaze wifi. Tested it several tines every time I turn it on the WiFi on amaze takes a dive and eventually dissconnects. I really feel like throwing my iPod out the window for all the headache and trouble it caused.

When I try to connect to my home network with my ipod connected to my wifi at the same time my Htc amaze will connect to the wifi but it'll drop to one bar and hold the connection for like 30s. This happens with Stock ics from htc, Speedy Rom, Energy rom. However, once I turn off the wifi on my iPod 4th gen my htc amaze is able to properly connect at full bar without dropping wifi connection.
Phone specs
rom ICS Energy Rom Aug 6th
kernal Htc Stock ics
Bootloader unlocked s on
My router is a cheap one send from telus called Siemens Gigaset SE567.
This might just be a case that only happens to me other people may not have this problem.

Sounds like router tho not ipod. Have you looked into updating the firmware for that router? Maybe if you call them they can replace for a better one.

[Q] Xperia tablet Z loses WIFI connection regularly

Just bought a Xperia tablet Z and am having problems with it remaining connected to my WIFI. It's updated to the latest software release.
Initial connection is good and shows good signal strength and works as normal. Periodically the WIFI then disconnects and shows "authentication problem" against the network and most often needs a manual connect to regain the connection, even though occasionally reconnects by itself after 10-15 seconds.
When the WIFI network disconnects I have to manual reconnect (the error message is "authentication problem" ). Once I have reconnected, the WIFI works OK for a short while (3-10 mins) and then i get the error message again.
If I restart the Xperia the problem goes away for a relatively longer length of time however it soon comes back ( after 30 minutes+).
I have many other devices connected to the WIFI during this period all of which work fine. WIFI analysis shows excellent signal strength - the tablet drops the connection even while two feet away from the router - and good signal to noise ratio. Looks like a bug in the firmware to me.
Any assistance would be good.
Note: there is a very similar thread here Sony mobile forum from which I have copied a lot of the info as I am having exactly the same problem

I thought I was the only with this problem...this happens to me almost four times a day where the wifi would just lose it's connection and I have to reconnect manually. I hope this is a bug and not my tablet...
Look, unfortunately this is a problem that has been dragging from sony tablet s and xperia tablet s (which I have).
What you can do (like me) is to use advanced wifi lock (in google play). That will not disconnect the antenna. It is a temporary solution but it's something.

Just spoke with Sony assistance, they said to return it and ask for replacement. No attempt to debug whatsoever.
Well i used to have this issue, it was very annonying. Definitely the problem was not the tablet it was the router. The problem is that usually all the routers have the channel value set to auto, so if you put it on 9-10, and restart the router, you won't face this again.
I did that and so far the wifi is stable for my tablet, and even my Macbook seems to have a better connection.
I experienced the same problems with both my tablet and phone (XZ). I got better switching the channel in the router. However, now it's solved. The solution came when I got FTTH installed at home and my ISP replaced my router. Since then, no more wifi disconnections. So I guess the problem was in the router.

For security reasons, the app I mentioned (advanced wifi lock free) causes a boot animation loop in tablets xperia s (and others). So, be careful for readers post.

Same thing here, plus WiFi performance seems to be particulary weak with this tablet in general. I get three "bars" only when I'm right next to the router. When I'm outside on my porch (about 10 meters from the box and two walls inbetween) I get merely one bar and WiFi drops or simply "stalls" after a few minutes. I already set the router to a fixed channel. I have this problem only with the Sony tablet, our other devices (Thinkpad laptop, Iphone 4S, SGSII and SGSIII, iPad 4) all have a perfectly fast and stable connection even in the "porch scenario".
I really hope Sony improves this with the next firmware update! Any hints besides WiFi repeater, which I already ordered?
Just to update my original post, my replacement tablet has been connected for about 20 hrs now and it has dropped the FIFI signal only once (even signal reception is not very strong in comparison to my Samsung Galaxy III phone).
I don't know if it is of any benefit, but I have also installed this app
That's a bulls**t app, has no effect.
I'm in love with this tablet and want to buy it immediately, but this issue is scaring the hell out of me as I mainly use only Wi-Fi to connect to the internet. Are there at least a few of you who have no Wi-Fi connectivity issues at all?

I've had my Tablet Z for about 10 days. In that time I've used it with my WiFi at home and at work ( WiFi tethered to my Nexus 4). In both cases, I've never been more than 3m from the WiFi source. In all that time I think I've dropped the connection only once.
I've watched (streaming with WiFi) a few tv programmes of about 1hr each, and they have played without a problem.
I've just used an app called WiFi analyzer to compare the signal strength on my Nexus 4 with the Tablet Z at different places around my house and the signal strength is the same on the phone and tablet.
So, as far as I can tell, if you've got a decent WiFi signal, you should have no problems.
I've used both CM10.1 and Sony stock ROM (.370) over that period (mostly the Sony ROM).
I've had very similar problem with Mac. I have established the static IP addresses for all my wireless and wired devices and it seemed like it worked but after a while my laptop started losing connection again. I know you might not like my answer but the only solution to this problem is a new router. When I ran d-link WBR-1310, I've had all kind of problems and since I replaced it with Netgear WNR3500 I have not had a lost connection yet. Not even once. 3 different laptops, MacBook, Xperia Tablet Z, bunch of iPhones, iPads and Android phones work like a charm. BTW all my devices have assigned local static IP addresses. Hopefully that will solve your problem.
I have found a possible fix! Please test for yourself whether it works for you and report!
I have disabled the app "Smart Connect". (It's a system app, so it's only possible to disable it via "Titanium Backup" or a similar app on a rooted device.)
Now the WiFi doesn't lose connection anymore when it's weak.

I had issues with this as well, with my ASUS rt-n66u router. However, I was using DDWRT at the time, and swapping back, with mostly default settings, to the stock firmware resolved the issue entirely. I've now not had any drops on either the 5 or 2.4 ghz bands.
has anyone found a concrete reason as to why the tablet either drops the wifi connection or there's the authentication problem?
my tablet was dropping the wifi connection so i changed the router's channel to 9 and it doens't drop the wifi connection after that
however (i dont know if this is related) my tablet turns off the wifi radio when the screen is locked for a longer period of time even when i keep stamina mode off (although i read it only turns off the data connection radio) and i set the wifi radio to always be on even when the screen is locked
also after changing the router's channel to 9, i get the authentication problem ._.
EDIT:
If anyone would be willing to share, what authentication method and encryption are you using for your wireless network? And does your tablet keep a stable connection?
I'm currently using WPA-Personal with TKIP encryption and i come up with both dropped connections and the authentication errors. (trying to diagnose this in hopes of not having to return my device because it's defective)

Weird Wifi issue

Hello everybody,
Recently Ive come across weird issue with connection between Xperia Z2-Router-Other devices. I had Xperia Z,Z1 and Z2 but only the last one is making some problems. The problem is whenever I connect it to my home wifi device the other devices like PCs and Laptops almost loose any connection. I mean there is a great signal but Internet connection becomes extremely slow as if Xperia Z2 was downloading 10gb of some random data. For a few days I had been thinking it was just my Internet provider problem but then I switched off Xperia's wifi and guess what...every device in da house boosted up with its connection. Thats strange... And now what I do is disconnecting Xperia every time I or the others in my house are going to use Internet. You can imagine how frustraiting it is. Any suggestions? Maybe my wifi device is too old, some parameters does not match? What should I look for? And please do not suggest turn on/off phone, checking whether I download sthing at the time or any other simple solution, as Im not that "dark" in my "darkness" lol. Greetings from POLANDia

I see no responses but for all of you facing/who will be facing similiar problem thats fault of router. Today I bought new one, the old one isnt broken its just old some parameters doesnt match I guess with newest technologies used in Z2. New one works perfect, all devices connected and working good.
