Hello, my recommendation: just stay with trisquel and all is fine :-) The "old" GNS is too obsolete, like krofna said. Did you try the "gns 3 beta"?
I had it another way, gns first (incl. being offline for a while, had to get sakis3g and stuff, no proper browser (afair)). Beta is pretty OK. I like how they stay with gnome2, BUT... AFAIK there is no(!) SMP support (this is K.O. criteria, for me at least), so I dloaded latest stable trisquel and everything is just fine, worked out-of-the-box and only few minor modifications had to be done manually. (wireless (atheros), some mobile broadband modems and stuff., impressive "user experience, compact etc) Just perfect and 100% free. If a device does not run, perhaps there is no appropriate open-source driver/firmware.
Enjoy it! Regards, ...
