I need a wired router, I don't really want to spend more than £30-50 but I have no idea about which to get as I have never had one before or even if my budget is realistic. I absolutly don't want a wireless one or one that even does wireless, as I don't want even the remote possibility of anyone DLing things they shouldn't off it. I have Virgin cable BB and live in the UK, I need the conn to share between 4 comps, but 5 would be better so I can just stick the PS3 on it too. Thanks for any help edit: Or can I get away with just a switch? I don't know what they are either >_<
I have the modem, goes from modem to comp at moment. Theres a big distance between the two as well, my comps are no where near my modem, thats downstairs, comps are upstairs. No good with the superhub splitting the conn downstairs then having to run 5 wires upstairs. I just want to run one wire up here and split it in the comp room.
Well a switch will allow you to extend from the modem - as you want with one cable - and will then provide however many connections to your devices. I would probably recommend an 8-port gigabit switch such as this: http://www.scan.co.uk/products/netgear-gs108uk-8-port-gigabit-10-100-1000-prosafe-unmanaged-switch I think it would just require changes to some settings in the modem but I have never done it so not sure about this.
I agree a basic Xport gigabit switch would be more ideal for your application. Since most modems these days are actually 1port routers, there is no reason to get an additional router for wired. You end up using it as a switch anyway since you must disable a 2nd routers dhcp server etc. Switches are also about half the price and are often available in much more robust metal enclosures. The one linked by Jeevus is a good example. Others I have personal good experience with are trendnet (often cheaper than netgear and just as good) and HP (though mostly over the top and likely out of budget).
Watch out though. If the modem assigns the computer directly linked to it an address not similar to 192.168.*.*, 172.16.*.*, or 10.*.*.*, then you need a router connected to the modem. A switch simply gives the modem multiple connections - which means that your ISP would need to give out separate IPs for each connected computer. Which is impossible. So a router connects to the modem, and then switches extend the functionality of the router. Of course, if the modem does give out a private IP address on the inside, then all you need is a switch. Somehow I doubt it though.
I picked up a Dlink 8 port Gb switch for about £15 on ebay a few years ago and it's done me proud. However, if you only need to share internet around then 100Mb is fine, Gb comes into it's own if you're transfering files around, or streaming files.
