[Q] Xperia T Wi-Fi problem

I just got an Sony Xperia T,
now I was trying to connect is to my router with the 5ghz-band, but the Xperia T can't find the network,
so then manually added the network, inserterd password, but then it says that the network isn't within reach,
but i'm sitting next to the router, the 2.4ghz-band works fine, and sony confirms that the phone should work with
the 5ghz-band in the white paper of the phone. Does anyone know how to solve this problem?
BTW, my router is a Netgear WNDR3700 Dual Band.

On your router have you set it to dual band as a lot of the time they have it defaulted to 2.4 b/g so you'd need to change it to auto or whatever option allows all. On my Linksys it says 2.4 and 5 as an option in the dropdown. That would be the only reason I can think of. Have you tried with any other device to connect to your 5ghz network?

Likely a router compatibility issue. I can connect to a Linksys e4200 on 5ghz with no problems

My Xperia T refuses to connect to my WiFi AP. It's only 2.4GHz, but according to the logs on the AP, it isn't even trying. On the phone side I very briefly see "Connecting" or similar on the AP list, then it reverts to Saved.
Log on phone is filled with entries like this:
Code:
I/wpa_supplicant( 565): wlan0: Trying to associate with 00:0c:42:XX:XX:XX (SSID='LFWnet' freq=2412 MHz)
I/wpa_supplicant( 565): wlan0: CTRL-EVENT-ASSOC-REJECT bssid=00:0c:42:XX:XX:XX status_code=1
MAC's partially XX'd
This happened on the stock Vodafone ROM, and still occurs on the Generic UK posted in General. I have tried WPA and WPA2, TKIP and AES, different channels, disabling N etc etc, still the same
Tried soft/hard reboots, wipes etc, nothing. It has connected to other public and protected AP's fine.
Am gutted as changing my AP to work around this problem is a no-go. Not had any problems with various other laptops and phones, including other SE/Xperia devices.

I'm on generic UK rom and using a BT Home Hub without any problems. I've also got my old dLink wireless n router I use as a print server and it works fine with that too. My brother has a Sky router (Netgear I think) and that works fine.
I think you must be unlucky.

Is your SSID published? Have you tried turning off all security on the router to see if you can connect then? (obviously I'm not suggesting you leave it unsecured but it is something to try.)
Also, posting your router details may give you an idea if others have been successful with that router before you splash any cash on a new one.

Hi, my Xperia T also is not able to connect with my e4200 5 GHz WiFi. My Laptop and a Samsung Phone works without any problems... I read (sorry I don´t remember the forum link) Sony did not enable the 5 GHz frequency because of driver issues. But if it works on some phones, maybe it´s a provider specific issue like the permanent bootloader lock?

Might be worth updating the firmware of your router?

I think I found the problem, the 5ghz band of my router doesn't have much range appearently, when i'm trying to find the 5ghz band outside of my house, i can't find it, I can only find it when i'm in my room, that's where the router stands, but the 2.4 ghz band has a much better range, I can connect to is almost 20-30 meters outside of my house. I'm wondering when Netgear is coming out with an update for my router, hopefully that will solve the problem, or maybe it will be solved when the Xperia T gets an update to Jelly Bean.

Hi there,
I've just bought the Xperia T and I'm pretty disappointed I can't use my home wifi.
I'm having exactly the same problem - I can see my connection and connect (sometimes) but it is a very poor connection, then after a minute or says "Not in range". If I go outside (which is actually closer to where the modem is) I can get data at an acceptable speed.
Sorry I'm such a noob but can you explain to me where the limitation lies and how I might fix it. Every other device used in the house works - even an old iphone 3gs - I'm surprised Sony's newest phone hasn't implemented technology that must have been in use for years.
Or if it is the modem - any ideas on how to change it.
Sorry - can't give you details - the modem is locked in the landlords garage - so I can't see what make it is.
Thanks for helping a noob.

I have faced the same problem with my TX when connecting to my AP.
I think there is WIFI problem in receiving the WIFI signal of security mode WPA2/WPA.
You can change the WIFI security mode to WEP or No security.
My device can connect the WEP mode WIFI.
Hope you can solve the problem!

Hmmm, that's strange - my modem is set to WEP and it's not really a connection problem but a signal strength problem. But like I said - no other device has this issue. It is hard to test - right now I'm accessing this from a cloud connection which is average compared to another I used this morning, though much better than at home. But I don't know how close I am to the transmitter right now.

Hello again,
I'm still trying to get to the bottom of this:
So my Xperia T can connect and use the wifi in my house fine IF I am within 2-3 metres of my router, which has the following settings -
O2 Wireless Box, model - TG585v7
Software release - 8.2.7.7
Boot loader 1.0.0
Interface Type: 802.11b/g
Band: 2.4G Hz (This unfortunately cannot be changed)
It is currently set to WEP security but when I changed to WPA-2 there was still no change - could only connect when a couple of metres away.
Also even when holding my phone 10cm away from the router I still only get a "Good" connection. So I started to think it must be my phone that is faulty - I've been to coffee shops and picked up the free Cloud wifi ok, though one kept dropping in and out. And I have been into mobile phone shops testing their wifi and it connects.
But yesterday I went to Carphone Warehouse and compared to one of their demo Xperia T phones - the demo was connected to their wifi fine yet my phone could not even "see" their connection - I was sure it was my phone.
But now I'm really confused - today I went to a different Carphone warehouse - there was no demo phone but I picked up their signal and the quality was "Excellent" - something I'd never seen before.
My phone is locked to T-Mobile - can a carrier locked phone somehow restrict access to certain routers?? Seems very weird to me, though I am quite a novice at all of this.
Any help would be much appreciated.
Thanks.

locked phone won't block AP access... maybe backup your data and try master reset.. factory reset... don't need erase sd card.

Are you using the T-Mobile WiFi app? If so delete your connection from settings, then set your home WiFi via the T-Mobile app, it may be connecting to the open one not your full one.
If you don't use the app, I would change the channel on the router and try that.

I use Xperia T in Turkey but I bought ıt in Bosnia. I checked my phone's ID and ın myphone has got Vodafone Wi-Fi .. When My phone's Wi-Fi is online then suddenly myphone begin afresh itself. What is the problem please help me ..

I had the same problem then I discovered it happen only in stock firmware or stock based ROM. Try Flashing CM10 or CM10.1. Your problem will likely be solved.

Not working: 802.1X / WPA2 / PEAP TTLS MSCHAPV2

Hi,
I'm trying to connect to a WiFi network that is protected with WPA2 with PEAP / TTLS.
It simply is not working. No problems connecting with my HTC Desire though.
Anybody experiencing the same bug? I already installed the required root certificates, tried various combinations of user account / password. The thing is, that the network is provided by my university (Eduroam if you are familiar with that) and it is very annoying that I have to fall back to HSDPA consuming my data quota.
Cheers,
chross

Normally with eduroam wifi there isn't wpa2 or other key. Just connect your phone to it, open your browser and you will be redirect to the website of your university and then you can log with your id.
Envoyé depuis mon XT890

Yes!! This is the exact same problem I'm having with my university wifi
http://forum.xda-developers.com/showpost.php?p=33962871&postcount=2
I'd configure the settings on my uni wifi choosing PEAP and then MSCHAPV2 and put in my log in username and password according to the instruction and as soon as press connect or save it looses the signal immediately to very low and never connects. We also have eduroam as an alternative they tried that and same problem just doesn't want to connect.
It works perfect on my htc one x. I'm beginning to believe the phone has a bug.

It does have a bug. It doesn't connect to 802.11 n!
My problem was solved by reconfiguring my AVW Fritz!Box 7270 to 802.11 b+g only and limit the phones wifi frequency to 2,4ghz only. You can find that in advanced wifi configuration.
I'm lucky i only recognized this bug in my own wifi network and not others i don't have admin rights for...

eduroam works for me with PEAP/TTLS but I guess it's 802.11g
I'm on the 40002 rom, but worked also on the 31006

After receiving the 4.0.4 update yesterday, WiFi now works flawlessly.
Cheers,
chross

Hi there,
I got the same problem with my university network in hamburg. I updated the razor to android 4.0.4 (Stock-Rom: 81.5.40002.XT890.Retail.en.EU), also the phone is rooted but still not working. Our IT advices to use WPA2 Enterprise TTLS/PAP authenthication in combination with a t-com root certificate. Every time i safe these setting the wifi signal drops as told by previous posters and the connection fails. When i enter the settingspage again, all settings are reverted to default. This also happens, while trying to connect to eduroam
any further advices?
Thanks in advance!

I have no problems connecting to eduroam at Braunschweig and other citys. Maybe you can visit the IT Desk at your university?

Yep, me and and a fellow student went there and told them about the problem. But they also gave up, after trying about an hour or so. It seems to be a general problem in the used android build, at least there are a lot of post reporting this at the google code repo -> code.google. com /p/android/issues/detail?id=15631 (sorry for that but I'm to new here to post links). I'll try the provided tips like changing the wpa_suplicant file tomorrow and report the results. Seems to be strange issue, if it works for you (and probably others), because a fellow student got the same Phone and has the same issues

Thought I'd just give an update as I have the same issue
Motorola knows about it, it's been reported to them before and said it'll be fixed with the next update.

Working smooth here with WPA2-Enterprise, PEAP and MSCHAPv2. Using it every day.
But I'm not using TTLS, you might want to disable that if you don't have a valid certificate for your mobile/user.
Also important, fill out the "anonymous user" field with your username. Depending on the RADIUS configuration of your IT this might be required.
[edit]
Just checked my mobile. I don't use a Phase 2 authentication, only EAP = PEAP, no certificates.

Got it working!
After 2 hours of searching the web and playing around, I got it working now, following this guide posted on google code repo:
Razr I (XT890), retail eu, running android 4.0.4 (stock), no root
after endless hours of trying i was able to connect to my university network a couple of minutes ago with the combination of two apps.
1. WiFi Connection Manager
Enter SSID manually
Security "802.1x EAP"
EAP Method "PEAP"
Phase 2 authentication "MSCHAPV2"
Identity "your identity"
Anonymous identity "your identity"
password "your password".
2. WiFi Advanced Configuration Editor
Check Hidden SSID
Key Management: unselect IEEE8021X, select WPA_EAP
AUTH Protocols: select LEAP
Enterprise configuration: make sure Identity and Anonymous Identity are set to your identity, Enter your password
check whether the settings are saved in WIFI Advanced Configuration Editor. If not switch of stock WiFi and repeat step 2 (!!!). Now it should work.
Turn WiFi on and connect to network (Stock WiFi; don't care about settings there, phase 2 authentification is still not saved)
After switching the device off and back on it did still work. Same when leaving and returning to WiFi area.
hopefully it will keep on working. i just tested the browser and play store. didn't discover any problems so far.

Connection is stable, but there seem to be some problems regarding to the speed. Whatever it's usable for stuff you do regularly @university.
Hope that helps others, thanks to klemens

Thank you for sharing, this made me so happy!
It's those two apps which made my connection possible.
My eduroam configuration is quite different, but the apps did the trick. I fiddled with advanced wifi config editor alone for hours without any result.
Now I just hammered the config into those two apps and what can I say - proxydroid reported a connection a few seconds later.
I dont't know what Moto's Problem with 802.1X is.
Defy latest stock rom - no connection. With CM -> no problem.
Milestone 2 with stock rom - no connection. With CM -> no Problem.
Rarz I no connection with stock wifi manager . . .
My fellow students with their samsung devices seem so have no problem at all. ^^
(even Win Mobile 6 works, thats a little bit depressing)
btw, speed is fine here. 16Mbit up&down is more than I need on a phone.

Wifi connect/disconnect - SOLVED

Hey everyone,
I just picked up a Xperia Z1 and noticed that when it was connected to my Wifi it would disconnect and connect at random. My cell provider and sony technicial support didnt offer any useful assitance. They informed me to do a factory restore on my device and it didnt help. Finally I decided to change my wifi encryption on my router from WPA/WPA2 to WEP and tada.. It works. I no longer have any issue with my phone. But I would prefer if Sony would fix this so that I can use the more secure protocol

Glad you solved the problem but I don't think is an issue of every Z1. I use WAP2 with 128bit Password and no problem. But still other problems anyway so I think is all based on luck.

Have this problem now too please help!

Have the EXACT same issue - very frustrated as I have moved from iphone now to this that has an issue with one of the most simple tasks of a mobile these days!
Can someone more technically minded please explain - I know this is an issue this phone has with WEP settings, and yes I could change router settings etc to connect the phone, however - what if I am at an airport, coffee shop, etc? Obviously I cannot go change their settings!
I am going to New Zealand on Thursday and it is imperative I can connect to wifis easily.
Can anyone please let me know asap please
* is this an Xperia/Sony issue? My iPhone never struggled with any settings of routers, ever, nor have any Samsungs I owned.
* Do I face the issue that if a router has WEP settings in public then I may forget connection to it??
* I might have the chance to get a Samsung S4 before I go.....should I just go for it and cut my losses with the camera?
Thank you so much in advance!
Emma

I never know that was the problem, I wil try, thanks!

For a professional network penetrator it takes 5-10 minutes to crack your wifi with wep.
You really shouldn't go with wep. There was a fix for that problem, try to search a bit on this forum. However it involves root. It's your call. Aside from that: I don't have any problems with WPA.
Btw: few years ago those iPhones I supported were unable to log into WPA protected network. IPhones iPad, and iPod all alike. Gave me a huge headache.
Edit:
Airports or places like that should not be a problem. Most of those networks are unprotected. Access to those networks is most likely controlled by a nac device or application

Cannot access hidden WiFI network

Hi guys,
I was extremely happy with my shiny new Moto X (2nd Gen) (UK), which arrived on Monday, however I am since less pleased as I cannot connect to my office WiFi!
All other WiFi's are fine, but for whatever reason I CANNOT seem to connect to my office WiFi.
I have tried every single setting and the only conclusion I can rationalise is that it's because the SSID is hidden and the Moto X (at least my one) has a problem with this. I've tried restarting the phone, factory restored the phone, asked sysadmin to reset the router, tried changing WiFI Direct name, turned on "WiFI Optimisation" etc.
Nothing works. It just says "Saved, secured with WPA2". Every other device in the office works fine.
There is no MAC filtering and plenty of DHCP licenses available.
What kinda odf crap phone can't handle hidden SSID's? Also, Motorola support is a pile of crap! Been waiting to speak to one of them for 1 hour.
Anyone have any ideas?
Thanks,
TD

I'm connected to my office WiFi with hidden ssid...

So why can't I?!?
Apparently someone told me that hidden SSID's is a violation of the Wi-Fi protocol and hence is not supported in Android/Motorola devices. Guessing that's the reason why apps like: https://play.google.com/store/apps/details?id=jp.sourceforge.soopy.hidden.ssid.enabler&hl=en_GB exist..?
On the other hand, it seems like bullcrap if you and other can connect to hidden networks just fine?
No one know or have any advice on this issue?
Thanks,
Z

I don't now where you're problem is coming from but I swear I'm connected each work day on a Wi-Fi network with hidden SSID. But : when I have configured it for the first time my moto x was telling me that WiFi network was not reachable. Just waiting 5 minutes and voila, moto x was connected. It was exactly same situation with a nexus 5 on same WiFi network.
---------- Post added at 12:06 PM ---------- Previous post was at 12:05 PM ----------
So configure it, and then wait 5 minutes and see if it is now connected. Put your WiFi in always on mode even when idle.

Mine just says "Saved Secured with WPA/WPA2".
Just won't connect!!

Go to wifi settings scroll down and hit
ADD NETWORK
Next enter the ssid exactly it is case sensitive.
Next enter password.
If it doesn't connect then your works wifi may have Mac address filtering on.
In that case you have to have the I. T. guy manually allow you in.
Hope that helps
Nd8 deodexed Rooted and modded

As mentioned there is no Mac filtering and thus isn't a dhcp capacity issue. Everything is fine. All other devices including other 4.4.4 devices are connecting without issue.
Any other ideas..

Is it 2.4 or 5 GHz WiFi? Have you enabled both?

Not sure what band, but doubt that's the issue as works on both bands at home.
Using a great tool called "WiFi Connection Manager" from the Play Store, you can see the following network settings:
Interesting to see what the alert says when clicking into it:
Any ideas? Thinking it could be a Cisco hardware related issue!
Z

Interesting... Using google I can found a lot of people that have same problem as you. But... Hidden ssid is only for bad admins that still think this will protect them

Yeah but it's no excuse for Android and/or Motorola to not play nice with hidden SSIDs. This in my opinion is VERY poor.

It's not moto but android. But since 802.11 have never been designed to work with hidden ssid I don't know if we can complain about android. But I'm not an expert on this subject, so maybe and hopefully someone can explain us in a more detailed manner.

That would make sense if I hadn't been able to use other Android 4.4.x devices and versions to successfully connect to the same network..

I missed that point... You're right if other android devices are able to connect to the same network then it is probably a moto problem... But mine is working good with hidden ssid but the router is not a Cisco one. I suggest to contact moto support by chat ( not by phone ), you should have an answer.

Cisco router? Make sure it is on the latest firmware. There appears to be an issue with older Cisco firmware and the X, independent of broadcasting of SSID.

[I3113] WiFi issues

Hello together,
I have a weird issue with my Xperia 10 (I3113 with unlocked Bootloader on 53.1.A.2.2).
At work we use Cisco ISE Sponsor Portal to provide WiFi guest access. I login using my credentials and everything works fine.
After a while I have to re-authenticate - this happens multiple times per day.
I noticed a similar issue with my WiFi at home. The phone is connected to the WiFi but has no internet access (same phenomenon as at work).
Has somebody experience a similar issue? Is this maybe related to the unlocked bootloader?
Greetings

I had wifi issues before i4193. It disconnects then reconnect itself automatically. I read some thread for xperia phones sine im unable to find any discussion specific for xperia 10. Luckily i found something saying that it underestimate the signals for dual band routers with 2.4 and 5ghz. My router at home is dual band but sharing the same ssid. I have it separated and now problem no longer exist. I can connect either to 2.4 or 5ghz signal without being disconnected. Hope this help.

Thanks for your reply.
I'm gonna try 2.4 GHz only and give feedback
