Not entirely sure how to phrase that better, but I have a room far away from my wireless modem, and if there exists a router that picks up that signal, and allows me to then use ethernet ports from that, it would be perfect. I don't really want to run cat-5 cabling all the way over there, so if it could somehow just work from a wireless signal, it would be great Sorry if that doesn't quite make sense, I'm trying to explain this as best as I can.
You don't want an access point (that is what takes a wired connection and allows wireless clients to connect to it). You DO want a wireless bridge (that takes a wireless connection and allows wired clients to connect to it). Your best option is to buy a DD-WRT compatible router, flash with the latest version of DD-WRT and then set the router to bridging mode. It'll be less expensive than a standalone WiFi bridge and it'll be much more flexible. -hl718
Exactly that, just buy a second hand linksys wrt54g, flash it with dd-wrt and look up on the internet how to configure a wireless bridge (its easy) When done you can use the ethernet ports on the wrt :thumbsup:
Another option, probably not applicable here but worth noting none the less: You can also buy devices you plug into any mains supply socket in your house and transport network data through your electrical wiring, such as http://www.netgear.com/Products/PowerlineNetworking/PowerlineEthernetAdapters/XE102.aspx In your case you'd plug Cat5 from your wireless modem (assuming it has a switch built into it) into the adaptor and plug the adaptor into the wall plug socket. In the far away room you'd repeat this process. For places were wireless interference is high, this is a good alternative. Bandwidth is 14Mbps but that is fast enough for a lot of Internet connections.
I've got the 200mbit series here which cost me 39 euro's each (sitecom homeplug) and they work fine. Allthough I get max 60mbit over the network and 200 is useless anyway in a 100mbit network, the quality depends on if you stay in the same electricity group and amoung other things. Latency is crap and unstable but good enough for most stuff and as an alternative for wireless it's great, as wireless has the same issues anyway. PS: there are newer models of 1gbit as well.
