I want to do some testing on my existing internal NIC to see if it is the source of these problems and for this i need another wireless NIC and of at least mediocre quality because i would need that NIC for other uses inland and abroad and as an addition to rely on it as a fallback device.
Question is should i get USB, PCMCIA or replace existing internal part with new part? Don't know about last one as it is computer's internal device that was already included in laptop. Not to mention laptop was bought in 2006.
USB i read doesn't use DMA and relies heavily on CPU and can have problems with drivers messed up. Feasible to assume that PCMCIA fits best in my case but most of them are B/G and less often i see N standards.
