Hi all, I've had a good route through the internet, various discussions etc but cannot for the life of me work this one out (still holding fire on phoning the company for the time being...). Right: I'd purchased a wireless Buffalo WZR2-G300N Router a few days back as we've set up our daughter with a computer. As we currently run an iMac upstairs, connected (via CAT5 cable) from NTL/Virgin cable modem, an option was to install a wireless router in the house so she could recieve broadband in her bedroom. Set up was easy enough (installed wireless PCI card in the PC by the way) and the signal strength and average speed were very good (often 130Mps). The iMac works fine (using the CAT5 from the router previously directly from the cable modem) whether Airport is in use or not. The problem is with the PC (XP SP2) in as much as I can rarely connect to the internet (possible for 5 mins at a time). When it's connected, it's really fast (even when the connection/speed drops) so it's really frustrating. I'll admit I know little of the 'internal' bits of PC's - but with a little research can poke around somewhat. I've since reinstalled windows and associated drivers, just to freshen the PC up (it used to be my PC and is in fine working condition). Via DHCP it's been assigned an IP address of 192.168.11.4 (from 192.168.11.1). I've been (almost) constantly rebooting, resetting, powering down (and turning firewalls off) for the past couple of days and I thought I had a breakthrough earlier (downloading iTunes...up to 80%) before the internet 'vanished'. Again, whilst I cannot access the internet the connection is seemingly there and in good strength?!?!?! Really at the end of my tether with this one...I cannot begin to pinpoint a culprit. If anyone can suggest a reason where this is going wrong (and if I need to provide any further information) I would be most grateful! Many thanks.
