when the connection drops (ie rdy light flashing) check the ip address on the pc. If it is still a public ip, (starting with anything apart from 10, 169 or 192) try ipconfig /release, then ipconfig /renew .
What is the ip address then?
Also try accessing
http://192.168.100.1 - username and password both root, then post back the information showing there.
Oh and btw,
