WiFi Probelm (Can't see network when every other device can)

WiFi Probelm (Can't see network when every other device can)

I've just got a Xperia Z1. It is having problems connecting to my BiPAC 7800N router. The wifi mode is b/g/n. Every other device works fine. 

 

The only way I can get it to connect is to reset the phone. When the phone next boots up it connects straight away.

 

The phone is generally really good. However not being able to connect to my home network is a bit of a deal breaker. If I can’t solve it then I might have to take it back.

That sounds rather strange. We haven't been able to replicate any similar issues with Wi-Fi so far.

Check the Wi-Fi FAQ if any of those tips can help you. If not let us know.

Re: WiFi Probelm (Can't see network when every other device can)

Hi, i was Xperiencing the Z1-Reboot-to-Reconnect Issue when using Channel 13 on my FRITZ!Box 6360 Cable.
Switching to a free Channel below 10 solved this for me.
I wonder how ppl will troubleshoot this, when their AP is set to automatically use free Channels, picking one of the "Evil Channels" randomly.

Interesting - this is a bug, I have experience this myself, known good wifi Ap's suddenly show as out of range and the only way to get them available again is to turn the phone off and on, one in particular that I use is only 5 feet away from the phone and when connected shows full signal bars, this needs to be reported back to the Dev team as it is 100% a bug

WiFi Probelm (Can't connect to network when every other device can)

Hi,

I've a similar problem. Connecting to open WLAN works fine (either a or g). Connecting to an 802.1x encrypted network works fine. But I have no chance to connect to a Network that uses WPA/PSK with a login pjrase that consists just of upper and lower case letters (no ßäöü involved). other devices can connect on either a and g band.

 

Thanks

msa

Same issue,Made sure that my Router stayed at Chanel 9 (instead of Auto) to fix the issue.

I have also found a way to get round the issue without reboot

 

 

My phone picks up about 8 SSID's at my location, if I select them and use the forget option the wifi works as it should, so it seems that other AP's that my phone is detecting that I never connect too are causing an issue

 

I don't understand why the xperia ZU wifi worked flawlessly and yet the Z1 has issues, I'd have thought they ran the same software of very similar

I've been trying to replicate this here but i can't find any problem. Does this only happen when using a channel above 11? What country are you in and do you have mobile network reception?

Re: WiFi Probelm (Can't see network when every other device can)

This problem might be difficult to replicate as I strongly believe it has something to do with other AP in my close proximity that are being picked up by the phone

 

My orginal report was that an AP that I was connected to from my own router  became out of range or became out of range if I turned wifi off and on or the phone wakened up from sleep and the only way to see this AP in range again was to reboot the phone

 

Since I originally reported this I have found that messing with other AP's in my wifi list that were showing as in range but very weak brough my own AP back to in range and allowed me to connect as normal

 

Additionally I have now updated to latest Firmware and replicating the problem has not been possible for me, so I'm not sure if it is fixed or not. if it happens again I will report on this thread my findings
