I have set up a WRT54GS ver1.1 with DD WRT v 24 software. I have no trouble connecting wirelessly to the internet from any computer I have tried but I cannot share files and printers. I dont have any trouble doing this using a wired router.
The computers are using wrt54GS V2.0 routers operating in client mode also running the same software.
Sharing would not be so imporant except I want to download movies and music to my RV's computer. When traveling we also use the computer in the RV to keep all our photographs taken during a trip, I had hoped I could download these to one of the computers in my house wirelessly.For now I am doing this by copying to a USB drive.
I can share my files wirelessly with my neighbor who is using a stock Dlink router so I dont think its the Client settings.
Being able to access movies and music from outside my house was my main motivation for going wireless.
I dont think I made any changes to the router and it is set up with the default settings.
