Trying to help out my church with some wifi access. PLEASE give me a minute of your time and some advice... ISP Info ISP uses DSL IP range = 192.168.1.x DNS is different Gateway is 192.168.1.1 (or maybe 192.168.1.10) Test PCs Toshiba 2.0GHz laptop / Win XP Pro SP2 / USR Wifi PCMCIA card Custom-built 1.7GHz desktop / Win XP Pro SP2 / Integrated Intel NIC PROBLEM Of course, the default setup for the WRT54G v6 (stock; out of the box) is to use the IP range 192.168.1.x. As such, simply attaching the router to the network, the desktop to the router and using wifi from the laptop, I get NO connection to the Internet, etc. I'm no expert on these things, BUT I think the reason is that the ISP and the router are both trying to use the same IP range. So... I tried changing settings to get the laptop (via wifi) and PC (via wired) to connect to the router and then out to the Internet. a) Setup the router to use DHCP to assign IPs. Then, set the PCs to use DHCP for NIC cfg. NO CONNECTION. b) Changed IP range in router to 192.168.2.x. Left PCs setup per (a). NO CONNECTION. c) Left router cfg'd as (b), but statically matching "range" assigned IPs in PCs. NO CONNECTION. d) Switched and swapped everything around to try all variances from above. NO CONNECTION. During ONE of these change-a-roos, I was able to ping the router and the DNS server from the laptop (didn't try using the PC to ping). However, I couldn't get out passed the router using Firefox or IE. Also, couldn't ping yahoo.com by name/IP either. Just for a moment, I turned off the firewall on the laptop and PC. NO CONNECTION. LAPTOP: I use the laptop at work and home and on the road. It works fine with wifi card or wired connection = ALWAYS. PC: Remove the router from the equation and reboot the PC. Connect to the Internet without fail. Therefore, the problem seems to be the WRT54G. I returned it to factory defaults a couple of times, but that didn't help. I would appreciate ANY help getting this going. THANKS!
