Yesterday I changed my Fios router password by logging in on my computer and changing the wep key. this worked fine initially, but within an hour my router had spontaneously reverted back to the previous password. So I changed it again and this morning it once again has reverted back to the previous wep key. This is very frustrating, as I am attempting to keep a specific person of the network. Is there any reason this is happening, and how can I permanently change the key?
**Edit: the router login online is also resetting to the default "admin" and asking me to create a new username and password. is this an indication that the router has be reset?
