I've just bought a Nexus 7 and when I try to connect to my wifi network I get a "Authentication Problem" error on the nexus. My laptops and printer work fine on the wifi. My Nexus wifi has worked fine in at least 3 other different wifi areas. I have a router and modem. Can anyone advise me why I'm getting this problem and what I need to do to rectify it?
Some android phones have had an issue with the superhub, the current beta firmware (being tested shortly) should address this.
No one else has confirmed if this works, but try changing the wireless key type to tkip instead of aes and joining again with the phone, if it works you will need to rejoin the other devices again, if not put it back to aes.
The other solution which is not ideal is to put the superhub into modem mode and use your own router, this is of course more expensive, but will also avoid most of the known issues with the current R36 firmware.
I removed my AVG software but that made no difference. I then read somewhere that there was a conflict with the old Virginmedia Wireless Manager (which ran automatically on startup), so I've just removed that and this laptop is now connecting with no problem at all. I just have another laptop and a printer to sort and I'll give them a go tomorrow.
I deleted the Virginmedia Wireless Manager from the 2nd laptop and that too connected with no problem afterwards. Prior to that the signal been on/off about every 7 secs. Everything now up and running perfectly.
