A relative newbie to the mac world, and no expert on networking either, so bear with me. Ok to start with for internet access, I need one of these http://www.dsl-warehouse.co.uk/product.asp?pr=WRT54G3G which is basically a standard linksys wireless router, but which uses 3G signal I have an Apple Airport extreme the new rectangular n type, which is upstairs. I also have an Apple extreme older ufo type model. I have no choice re. the Linksys router, as it's my only internet alternative, and it must be kept upstairs in order to get 3G reception. I also need the new type airport extreme upstairs so I can have wireless printing and hdd access. Due to a concrete ceiling, I need wireless boost for downstairs, so was planning to use my older extreme for that. Now here comes the question, what is the best way of reliably connecting this lot up. The two upstairs routers are only a couple of feet apart, so will I disable wireless on one of them ? Which is a relay, remote, main etc. which does dhcp etc. I have Cat 5 running between all the routers which I can use etc. If anyone can give specific information, i.e down to which cable to plug where, which settings to use etc. please do, if I haven't given everyone a migraine already.
