Hello
Welcome to B1
So how is the router connected to the pc? USB?
I supose you already tried these but it is all I can think of:
- Reset the router by holding in the reset button for about 10 seconds
- Delete the connection in the connection settings
- Set up a new connection for it
- Ran the repair option on the connection
Also I think there were some MS-DOS commands that release and renew the ip address but I can't remember what they were now, sorry
Anyway hope this helps
