Can WIFI protocol be updated on cards?
 

Hi, I was looking for a laptop and the one I like just have a WIFI card with 22Mb/second. I'd like to know if protocol could be updated to get those 55Mb/sec (802.11 g?)... I mean, a kind of update or something.

Thnx in advance.

You can get a USB adaptor or Cardbus/PCMCIA adaptor which supports 802.11G

From what I know, you can't 'upgrade' a PCMCIA card to have increased bandwidth, you can only improne on the encryption types. Try thinking of it like this, if you want to upgrade your network card from a 100MB transfer rate to 1000MB then you would have to replace the part because you can't upgrade it.

You buy a better adaptor. That's generally what a hardware upgrade entails.

I have never heard of a firmware flash changing protocol types, different protocols on wifi call for completely different LSI or microcontrollers.
