first of all check your network adapter, simply put it has to be compatibile with the 5ghz frequency
once you're sure it does support this it will connect to a 5ghz wifi access point if one will be in range, without the need to switch anything
my qosmio does not support 5ghz, all ive got is the 2.4ghz one
I think the notebook supports Atheros 802.11(b/g/n) WB195-HMC WLan card.
The WLan standards 802.11 B and G operates at 2.4GHZ. Also the 802.11 N standard would operates at 2.4Ghz if 802.11 A is not supported.
It seems that Intel 5100 WLan card supports 802.11 A/B/G and N so it will operates at 2.4GHz and 5.0GHz.
The Wlan card is also available in miniPCIe format so it should be possible to insert this into the WLan slot on the mobo….but question is if the BIOS would supports this…
To be honest I don’t know… there are no info about that and according to some users here in the forum, it could be possible that notebook would not power up using new WLan card….
