Hi, hi. A friend gave us a 3Com wireless router and I was just experimenting with it but now I'm having problems. First the details: I'm typing this on a Windows XP Pro. Prior to the router, we had installed a D-Link ADSL Modem to this machine. Just a few minutes ago, I hooked up this DSL modem to the 3Com router. I reseted the modem, router, and the PC and it got me connected to the internet (my PC doesn't have a wireless card so everything was done using ethernet cables). But my MacBook sitting in the other room detects the 3Com wireless signals but won't connect to the internet! I opened up Command Prompt on the PC and looked at the IP address and Subnet mask (which is 255.255.255.0, and it's supposed to be right, I think). I also went to http://192.168.1.1 and the PC detected the 3Com router which brought me to the 3Com configuration page. I don't know what I'm supposed to do for the MacBook to connect to the internet because it detects the signal but it just won't load web pages or sign into MSN, but on the PC everything works fine. So it can't be the way I set up the modem and the router, right? Also, would anyone know how to secure my network? On the3Com configuration page, it said Encrypt but I don't know the difference between 128-bit WEP and 16-bit WEP? Thanks so much in advance! P.S.-I'm using PPOE and I don't know anything about the DHCP bit.
