internet suuplied via T-mobile wifi dongle working on XP computer 1 192.168.0.2 (It's all I've got while moving house)
3 x laptops (various os) attached through wifi via netgear wifi router, ips - 192.168.0.4, 192.168.0.5,192.168.0.6 (Laptop 3 is running a weird art project not compatible with proxies) Nabaztag Wifi Bunny 192.168.0.7 - claims she is ok with proxies, but isn't really.
If you own a Nabaztag Wireless Bunny, you will realise how hard life can be without one...
