Getting Netgear WPN824 Wireless Router to work with Broadxent 8120 DSL Modem/Router, ethernet works fine, DHCP fails when connected via wireless

I am forced to use a Broadxent 8120 Modem/Router due to restrictions from my ISP, LightningBolt. They claim that it can easily work with other wireless routers, but I can't for the life of me figure out how!

So far I have bridged the 8120 and connected it to my Netgear WPN824. I set up the 824 with the login and password of my PPoE account and I can connect to the internet with multiple computers but ONLY WHEN CONNECTED TO THE 824 VIA ETHERNET. I have the 824 set as a DHCP server and it works fine, giving multiple IP addresses to my two laptops but again, only when connected via ethernet.

When I try to connect to the 824 via the wireless card in my laptop (which works fine elsewhere) it does not get a proper IP address, either defaulting to the Private Address thing (169.154...) or, if I change the alternate configuration, to whatever IP address I set. If I set a random IP address in the alternate configuration (say 192.168.1.135) it will connect to the Netgear, but I will not be able to access the internet. Also, when I open up the configuration of the Netgear, I will be able to SEE the computers connected via ethernet (including the one with the wireless adapter if I have the cable plugged in) BUT both the IP address and the name of the computer using the wireless adapter is blank.

So, in short, I have the Netgear router connected to the bridged Broadxent 8120 and everything works EXCEPT ANYTHING WIRELESS, which is of course what I need and why I bought the damn Wireless Router in for first place!

Any and all help would be greatly appreciated. I have searched and searched for a solution to no avail.

Thanks,
