I spent five hours recently, getting a new Dell with Vista set up for a coworker. Could not ping out, no internet connection. Call Roadrunner, back and forth, back and forth, it’s a hardware problem, call Dell. Call Dell, go through at least four different tech support reps, none of whom had a firm grasp of English. Finally get a native English speaker, their best tech, and am told that the router is incompatible with Vista. Need a new router.
Five hours!
My Vista box decided it didn’t like the manual config that I set up to get it on my LAN. Double checked, everything was exactly right, still no go. Wiped the settings and started fresh using the *exact same info* and it worked.
Worth a try before shelling out for a new router, which sounds pretty fishy to me.
