ok...i managed to change the ip of the router. i noticed that there are 2 ip addresses (2 ways to connect to it) so that if i change 1 i can still connect via the other ip.
anyway...i also had to change the default gateway on each computer on the network. i also noticed that every so often my internet times out periodically...for example, it will be working fine (no problems with any site, signing in, syncronizing files with outlook, etc)....i saw that it looks normal when clicking on local connection where the packets are being sent and received.....
could this have anything to do with what i did? as i never had a problem like this before..
