I have a situation where the internet connection is lost on all three computers connected to a wireless router. Unplug the power cord to the router, wait 1 minute, plug it back in, and the internet is connected again.
This is a scenario with my sister's network. They have a Comcast broadband with a modem that connects the TV,Phone and the internet. They have a Netgear WGT624 v2 router. I replaced the router with a new WRT150N Linksys wireless n. By the way, one desktop is wired via rj45 to the router. I noticed that when I remove the router and connected the desktop to the modem, I cannot connect to the internet at all. I had to power cycle it three times and finally, I tried the command:
NETSH INT IP RESET, rebooted the system and it worked. I connected the Linksys WRT150N and everything is ok until after 4 hours. One computer that is connected wirelessly couldn't get an IP. So they tried the pull the power plug thing from the Linksys router and it worked again.
Could it be the modem? Any help will be greatly appreciated. Thanks in advance. Sorry for the long post.
