> Can you recommend or suggest suitable (and not too expensive) wireless kit.
Sorry for the slow response.
I've been very happy with Solwise (www.solwise.co.uk). Their prices seem reasonable and their service is very good. A particular plus point is their user forums which are very active and a helpful source of advice. Also they were quick to reply to questions I posed by e-mail.
I have an SAR715PW modem/router and Asus WL100 wireless PCMCIA cards from them.
