If so, connect wired and change it back. Then put a password on the router access.
Hi everyone... a little help here please..I'm pulling my hair out over this one and it's probably a simple fix known by someone..
I have been running an Acer Aspire One on Linux lite for a couple of years successfully on WLAN through a belkin router on WPA2 Personal security level with a 16 digit security key. The other day the connection was pretty bad, probably contention at the exchange and I needed connection immediatley. I'm sorry to say, I scanned for any other open networks in my region and found an open WLAN so connected to that and used it, deleting the connection from connection manager immediately after. When I went back later on that day to re-connect to my own WLAN, the connection manager has changed my security key from the 16 digit key to an unknown 63 digit one and I connsequently can't connect. LAN is fine through the same router but WLAN wont connect because of this change of security key. Other WLAN netbooks connect fine.
I tried deleting the connection from connection manager and re-creating it, but connection manager wizard still changes the security key from what I enter to this unknown 63 digit key, even before I try to activate the connnection !!!
Any ideas ?
