My brother and I (who stays across the road) both have an internet dsl connection through WRT54G router, WPA2.

The neighborhood that we are in has rather old infrastructure, the lines are not very reliable, needing frequent maintenance.


Today my line is down again and I am using my laptop (Debian KDE4) to connect to his network while sitting near my main gate.
I am able to connect to his network ONLY at my main entrance, those in my house couldn't receive the signal.

The maintenance will drag on for a few days, hopefully not more then 1-2 week.


How can I share my laptop connection and pipe it to my WRT54G router to re-broadcast so that my other computers inside the house can connect to?

The way I did ( I have same router as you have ... ) I spoofed MAC addresss of router ( just see which MAC address router has and assign it to your computer NIC ---this is in case your provider locked up ip to only on mac address ).

Once you do that, use an 30 $ box, iptables, an old switch and set up your own router/gateway. This way is more difficult but, more interesting

Second option is connect your laptop to WRT54G, open browser and enter ip address of router

username=admin, password = admin....

http://192.168.1.1 ( in browser of your computer conected to WRT54G )

once you are logged to it, then in wireless options , you will see to set up mac addresses of your machines which should be allowe to connect ( this is funny, read above, MAC addresses are changeable )...

So my choice is option one, as better for control

Hope this helps

From your position, you can connect wirelessly to either your own or your freinds WAP/router, but people in your building can only connect to your one??? So you want to wirelessly make your connection via your freind available to your own network.

What you need is the right search terms - instructions would help but they tend to get convoluted.

You want either

wireless repeater

or set up your laptop as an invisible proxy, shunting internet requests.

Which is to say, internet requests at your lan need to be routed to your laptop - your laptop can then forward them to your friend's gateway.

either way you need two nics.

This will probably be a tad involved for the short-term you are looking for.
Talk to your ISP about a temporary wireless internet connection.
