hi, there
My network has the following configuration

Speedtouch 516v6 is a router (single rj) and i leave PPPoE with it.

Internet is ok. I can control it accessing speedtouch webpage at 10.0.0.138 (192.168.1.254 doesn't work though)
Wired Clients (LAN) have no problem at all acquiring network address.
Wireless clients have the following problem. Both clients can connect for the first time simultaneously, but if one disconnects and try to reconnect, both computers loose connection and get the "The connection has limted or no connectivity" and the only solution is to turn off and on the wireless device ( I use XWRT btw with kamikaze 7.09) or reboot the device. I can detect the network but no connection, and reading log file, looks like it doesn't even "react" to my wireless clients, there's no DHCPOFFER, there's no DISCOVER, nothing....

What could be the problem, doc?

(I've already tried to give fixed IPs by mac, same thing though...)

I have samba, usb and print server, etc, but i think there's no relation with it...
Problem is router does not give IPs to my clients

regards
sorry for bad english

I also got an ASUS WL-500g Premium an I got the same problem! Anyone got an solution.

You said the only solution is rebooting the wireless device.  What does `wifi down ; wifi up` do?

You said the DHCP server doesn't offer an address, but before that, you mentioned "The connection has limited or no connectivity."  I can't remember if that means DHCP failed or link-level association failed.  Does iwlist say if either client is associated?

What wireless cards are the clients using?

sorry m8, and thanks anyway

I'm with DDwrt now and everything is working fine
