This is an odd problem...I reckon. My Belkin router of about 8 or so years started cutting out. I bought a Linksys WRT54GL based on good reviews and reasonable price. I ran the setup.exe and could not complete it cause I couldn't get an internet connection. I unplugged everything and ran my ethernet from the computer right into the cable modem and same thing, no connection. I plugged back into the old Belkin router and got a connection. Almost as if my IP and all related information is only working via the Belkin router if that is possible.
Every time I unplug the connection from either router and plug it back into another, or the modem itself, the computer network icon in the sys tray has the yellow bouncy ball thingy and says it is 'acquiring network address'. As soon as I go into it's properties and check the IP and Gateway etc numbers and hit 'ok', it goes back to the regular network icon, but again, is only connected to the net if plugged into the old Belkin router.
I hope I explained this ok...I'm baffled
Any help is greatly appreciated.
