Use wireless as a WAN port, in place of the wired WAN port?

    Not sure if I've worded the title well or not, but it sums up what I want to do.

    In more detail...

    I currently have a cable modem attached to my Linksys WRT54GS v1.1 with Tomato 1.21 installed. Three computers are directly connected to the router's LAN ports, and a cable modem is attached to the WAN port (obviously). Nothing is connected to the router wirelessly, and wireless is turned off - unless I want to connect to a Wii, on the odd occasion.

    Now is it possible for my router to wirelessly pick up a connection, say from a computer with a wireless card, and use that in place of the WAN port? Ie: I completely unplug my cable modem from the router's WAN port, enable wireless on the router, and use the wireless computer to access the internet, through the router's wireless? So rather than get my internet connection from the WAN port, I get it wirelessly.

    If this is possible, how do I go about it exactly?

    The reason I ask, is I may be changing ISP soon, and want the option say to connect to a wireless router in a completely different location of the house, without running a wire to my router's WAN port. I fully realise it's a more complicated way of going about things, but I want to know if that option is open to me?

    Are you sure this is what you're looking for? Your last paragraph sounds more like you'd like a WDS..
    Or do you actually have an ISP which has a wireless AP in your neighborhood (would need to be really close as WLAN range is rather limited) and to which you can connect to?

    Unless I'm mistaken, this is what Wireless Client mode does.

    "Repeater bridge" on router #2 will enable you to extend the current signal provided by Wifi AP #1 and let u hook into router #2 using a cable.

    "Repeater bridge" is what you want as "client bridge" will act like a computer with ICS.

    catch my drift

    Well there is an ISP with an AP in my neighbourhood, which I suppose might come in handy for a backup connect - but this would obviously be rather naughty of me to do. :p
    No idea what Wireless Client mode is, or where to find it. :confused::eyebrow:
    Ok, let's say I wanted to connect to another router in my house, what would I need to change and where? I don't see these bridge modes.

    It is one of the "Wireless Mode" options in the basic network settings.

    It will treat the wireless connection like the WAN port, including NAT, etc. CaNsA mentions this as a negative, but it seems to be exactly what you were asking to do.

    Apparently, you need to self-apply patch #2...

    I kid, I kid...

    3 x 12hr night shifts in a secure data centre take there toll in this way.

    Unfortunately your suggestion would mean buying more equipment - I don't want to buy bridges. I just want to pick up a wireless signal, and that as my internet connection.
