    Hi, I'm very grateful that I found this site...I've learned a lot.

    I'm very new to networking (about a week). I bought a WRT54G & WMP54G and decided I was going to finally be able to share files between my two desktops....and I also wanted to share my NEW cable connection.
    Well, everything is working OK and I was just trying to beef up security a little...reset default router password, disabled broadcast of SSID, using a 64bit WEP key...but I also read somewhere that you should change the default subnet mask. When I try to do that I lose INTERNET access on both computers...can't even access the router from my main PC which is "wired" into the router and I end up having to reset the router and start all over.
    There is obviously something I'm missing..(like knowledge LOL)
    anyway I guess my questions would be:
    1. is it a good idea to set a non-default subnet mask??...and if so...
    2. how in the world do you do it????
    Oh, I should add that both my computers are running XP Pro SP1

    The reason you are losing connection to internet is most likely because of using an incorrect subnet mask. You have to use an appropriate subnet mask that includes both your router/gateway and your PCs. Google for "network calculator" if you have problem figuring out the proper subnet mask
