Problem with networking and 8 MB?

[Merax]

I have an Amiga 1200 with a Netgear wireless NIC and an MBX1200 memory expansion unit.

I recently upgraded the memory on the MBX from 4 MB to 8 MB (reported as working fine), but now I can't seem to get online anymore.  Easynet reports "add net default: gateway 192.168.1.1: Network is unreachable" when it tries to connect.  Also, the green status light on the wireless card doesn't come on anymore when I turn the machine on unless I pull the card out then plug it back in while the computer is on.

I wanted to know if there was a known issue with a full 8 MB expansion and PCMCIA cards by any chance before I put more wear and tear on the old hardware experimenting with it.

Thanks!

Well darn, that sucks.  Thanks for the fast answers though.  

Do the 1230 accelerators require a fan?  Can you still close the trapdoor at the bottom of the case?  Any compatibility problems?
