keep losing internet connection on home network

[mnmomof3]

i have a desktop with windows vista home premium that is hooked up to a broadband(comcast) modem and a Linksys wireless router(WRTG54G) which my laptop which is a toshiba satellite connects through. I have had this hooked up for the last 3 yrs without any problems. A few days ago while on my desktop i lost the internet connection....the laptop lost connection as well. however we still were connected to the local network. I clicked on diagnose and repair...then my internet connection would come back and the diagnose thing would say nothing was wrong, then a little while later the same thing would happen. I then did a ping from the laptop, to the desktop and the router...at that time it said 0% loss to the desktop and 50% loss to the router. Then i went to the routers page and reset the settings. I had no problems from yesterday morning until a few minutes ago, when again i lost internet connection.

Is it possible that theres something wrong with my router or could it be the modem? and how would i figure that out. we have cable and phone all through comcast through the same modem and arent having any problems at all with the cable or phone. Just the internet which is why im thinking its a router problem.

any help is appreciated.

thanks!

Some things you can try here.

1. For wireless connections, change the channel on the router, I like channels 1, 6, and 11 in the US.
2. For wireless connections, try moving either the wireless router/AP or the wireless computer. Even a couple of feet will sometimes make a big difference.
3. Update the firmware to the latest version available on the manufacturer's site.
4. Reset the router to factory defaults and reconfigure.

Many times these measures will resolve a lot of intermittent issues.
