Herman, unless you are trying to connect wirelessly to another SSID
with the same name as yours (this happens when people don't change
the name from the default), the router should be reset to factory
defaults using instructions from the vendor. there is usually a
reset hold where you insert a paper clip and hold for 10-15 seconds
or more or a reset button.
now, after the reset, before you attach the router to the modem,
login and change the password for the router itself. then, log in
and change the security to WPA2 or at least WPA and use a strong
passphrase.
if someone had access to your router wirelessly and changed the
settings, they also could have had access to shared files on your
computers, etc.
I need some urgent help. I have a wired connection from my windows XP
computer to a broadband router, and a wireless connection from my Vista
computer to this same router. I've had local and internet connections for a
many weeks. There was no encryption security or anything, but I didn't mind.
Suddenly I got disconnected from the router and now it's suddenly encrypted
with WEP and a network security key which I don't know!
What do I do? I really want my internet back (i'm using my XP computer which
does have internet).
