Problems with NM with new router

[Shawn Baker <scb147 comcast net>]

Hello,

I recently upgraded my router from a D-Link DI-624 to a TRENDnet 
TEW-611BRP router.  Network Manager 0.4.1 on Ubuntu 5.10 connecting to 
my D-Link worked great using DHCP and WEP.  The radio in the D-Link 
starting failing, so hence the reason for the new router.

Anyways, when I first connected the TRENDnet right out of the box, using 
a wired connection, NM wouldn't acquire an IP from the router.  It kept 
trying to renew it.  I have a copy of the log file from the router, and 
here are a couple entries from it:

--------- BEING LOG ---------

--------- END LOG ---------

As you can see, about every 3-5 seconds, NM keeps asking for an IP.  
Never did this with the D-Link.  I also tried connecting to the TRENDnet 
with the wireless, and it did the same thing.  I finally uninstalled NM 
and used Gnome Networking and it connects right up.

So, question is, is this a bug with NM?  Incompatibility of NM and this 
TRENDnet?  I haven't tried upgrading NM to the latest version, as I 
usually just wait for Ubuntu's repositories to upgrade.

Thanks for any suggestions!
