Network Issue on New Laptop

I've got my hands on a new Dell 9300 Inspiron laptop. I'm having some strange networking problems. OS is SLES-9. lspci lists the nic as : BCM4401-B0 100Base-TX (rev 02) The module that was loaded (selected automatically) is b44. On boot, eth0 is assigned a dhcp address, and the nameservers are properly populated in /etc/resolv.conf. So from this I know I am getting some connectivity. If I try to ping a device on my local subnet, I get: Destination Host Unreachable for a few hundred times Then I get very slow ping times(in the 10's of seconds) for a few hundred times Then I get sendmsg: No buffer space available I have tried using the bcm4400 drivers, and no luck there. What other suggestions would you have. Thanks, Ron
