I got myself the WAG54G Linksys Wireless Router/Gateway and it's crap. The wireless protocl connects at 1mb only (as opposed to 11mb) to my 802.11b network!
Been reading about this Router and its not just be but a general Linksys problem with this model so stay away.
Also ... another tip, if you were to get any router, use google or another popular search engine to search for the router e.g. search for "WAG54G Problems". That shall highlight the issues people may be facing with your particular brand of router.
thanks for the info ppl .. wasn't for me but my B-in-L .. he has telewest .. also turns out that he wants it also to use with x-box and so he got sorted ... i hope ... haven't heard from him so perhaps got probs ... or he got it sorted
