The other day I set up a lady's ADSL for her. PC connected directly to adsl modem, no problems all went well with the net.
Then she dug out a Netgear wifi router which she wants to use for her laptop. The power adaptor had died so I took the router back to the shop as I had a spare adaptor and I needed to see if the router was awol. Worked fine on the usual ip 192.168.1.1 and was able to get to the Netgear wizard page after a factory reset (password reset mainly). My pc had no probs picking it up, so went back to lady and connected modem to wan port of router, but i couldn't get the pc to pick up the ip of the router. Took the modem out of the loop and still it wouldn't find the router.
You have to get past the Netgear wizard before you can get to the main set up.
Then connected the router to her laptop which found it no problem. Then brought the adsl modem into the laptop/router loop and was able to run the wizard, dhcp auto and set up the wifi wpa security and bingo, internet via cable and wifi.
Took the whole lot back to the PC and tried again with all connected, PC connected to router through lan port.
Wifi internet no problem, but the PC still wouldn't find the router. Took the modem out of the loop again and it still wouldn't see the ip of the router.
Tried ip release then ip renew but the spanish windows message said no adaptor found or something.
Even when taking the modem out, the pc still shows the ip as 10.0.0.2 which is the ip of the modem.
I must be doing something fundamentally wrong here and it's got me foxed

Both PC and laptop running XP SP2.
