Since you referenced your pc as a laptop, rather than an iBook, G4, etc., I'll assume that you're running WinXP, but please confirm this or state otherwise. Open up a console window (Start/run/type "cmd" - w/o quote marks - & hit enter) and type "ipconfig" & hit enter; if the IP address is still a default (168.x.x.x) then type "ipconfig/renew" & hit enter; if you still get a default IP then type "cls" & hit enter & then type "ipconfig/all" & hit enter - it'll be a lot of info, but post everything that shows up.

When I go into diagnostic tools and click the IP Config tab, you have the option of clicking (1)IP Config, (2) Renew IP, (3) Release IP. When I select options 2 and 3, it fails. When I select option 1, I get the following:

Sorry I haven't replied sooner - I've come down with the flu. It's unlikely, but your router may not be confirmed to assign IP address. As a double check do the same ipconfig/all on one of your hardwired pc's and see if the line that says "Autoconfiguration Enabled" also says "Yes". Also, the wireless card itself may not be enabled. On my Toshiba there's an external switch to enable a wireless connection, even though the wireless card is integrated into the system. Another item is to redo the "ipconfig/renew" command and post whatever error message you receive.

hi you have to renew you`r new ip address on the new routear

Hi,
I have the same problems with my Fujitsu Siemens (FSC) Laptop with Intel PRO/Wireless 2100 3B PCI Miniadapter.

At home I have an Asus WLAN Router set up as an access-point, without DHCP. This router is connected to another router (not WLAN) that provides the DHCP-service. When I uses no password-protection it works OK. But when I activate WEP, it will not receive the IP-address anymore.

One other place I sometimes work with my Laptop, I have the same problem. At this place I can not turn off the password-protection. But if I use an USB WLAN-adapter it works OK.

A third place I use the Laptop, it works OK with WEP-protection too.

Due to some problems a couple of months ago I’ve installed Intel’s drivers instead of FSC’s drivers. But I did not test WEP at home, or this other place prior to the change of drivers...
