the broadcom wireless adapter gave me a hard time, and the ethernet adapter would always take control once connected... i had to run updates and get the correct drivers for the broadcom...

there is a setting in the network manager that makes the ethernet adapter only use it's own network resources, and not try to pig out on the wireless gateway...

now they cohabitate... i played around for some time with virtual adapters for the ethernet adapter but that was real pain in the ass... this is good...

i've also read that qinq on a 3550 leads to some difficulties as an l2 breakout switch(specifically one way cdp)... if that's the case then the choice will be a 3750 switch (known solution) or a gns server...

i'm still waiting on my other 3 3560's...

whatever the case, the idea of this ccie lab, as many have mentioned, is not to troubleshoot gns3 and the switches, but simply to get it stable and functioning correctly so the concentration is spent on the labs not the set up...
