I've just got a new desktop comp HP 3150 (vista) with built in Intel(R) PRO/100ve Network connection. I've tried to set it up with my old comp (486 series XP(SP2)/originally ME) with Realtek 10/100 NIC card seated in PCI slot using crossover cable(s) Both comps are showing the network icon (with red x) in the sys tray and bubble message "Network cable unplugged". Having trawled many forums such as these i have come across many 'solutions' and used them all in varying combnations, including: Installed as per instructions Re-installed Reseated card Tried alternative PCI slots & cables Tried to update driver (file on setup sotware is 2004 but there's no on-line support/update function for the NIC, so just finds it on the setup disc or in temp files on PC - so downloaded latest direct from RealTek - still nothing.) Changed settings from "autodetect/negotiation" to "100 fullplex & half, 10 full & half" Troubleshot both cards ("working properly") Installed LLTD protocol on XP comp (although i think this is irrelevant at this stage if either comp thinks there's no connection - same with network set up wizards, which i did anyway.) But no luck so far. Any ideas? I'm hoping to avoid the "get a router etc and go wireless" answer (unless there's no alternative) and I'm given the impression that a hub set up isn't necessary with two comps. Any help would be appreciated.
