Linksys WAG 54-GS Wireless worked fine for one day....

I have installed a Linksys gateway/router. (adsl)
The PC's connected by wire are working fine.

But the wifi is giving me a hard time.
I choosed for a WPA security setting.

1. A Thosiba Laptop was easily connected and wireless was working fine.
(almost plug & play)
2. A second laptop (Maxdata) was harder to connect, "Acuiring network
address" seems to stay forever. I do not got an IPaddress.

I aproached the Linksys, and connected the laptop by RJ45 and it was OK, the
wireless & 100BaseT both went on-line.

But, now the issue:
Now, after 1 day, no way anymore to connect wireless to the Linksys. NO way.
(3 different laptops, not ok )
I tried many things, even switched back to "no security" , it is connected,
but not getting an IP address.

I changed channels, changed from G to B to mixed

No way to get it connected.

Strange. (I can connect one laptop to an unprotected low & weak signal of
the neigbour's Netgear WiFi, but not my own Linksys....)

Just off the phone with linksys for a similar problem. from you main PC
not laptop, which ever one that was, go into the wireless router
config.under setup, mac address clone, click and save changes, reboot.
