Sharing an internet connection to a modem via a RJ45 to RJ11 cable

[harknett]

Wonder if anyone can help?
I currently share a internet connection on one of my computers with a neighbour via there wireless modem and want to make a network using a wireless router I have (Thompson TG585 v7). The router I have has a DSL and 4 ethernet outputs. I have been told that I can feed internet into the router via the ethernet card on my computer using a RJ45 to RJ11 cable, but having a bit of trouble trying to get a feed from the computer to the router, i have tried to look on the internet but can't come up with any awnsers.
Any suggestions would be highly appreciated.
Thanks

I see no reason to need an RJ-11. That is a phone line connector. It should go modem>router (via RJ-45)>computer (via RJ-45).

If you are getting a wireless signal from your neighbor into you computer and then want to feed that signal out your computer into your router....well I'm pretty sure you can't do that.

I think you might be able to do this with Internet connection sharing, a switch, and setting your computer as default gateway. You won't have dhcp though so you'll have to set your own ip addresses and stuff.

Yes you may not be able to do that....
