I recently bought an 802.11ac wifi adapter promising a nice theoretical 600Mbs in the 5Ghz band and all I was able to get from it was a practical 65-70Mbs (at 2 meters from an 802.11ac router) using the best drivers under Windows. Under Linux the (5Ghz)AC mode didn&#x27;t work (buggy driver; no vendor support) so I was back in 802.11n mode. Quite underwhelming after spending 200 euros on router and adapter. I will definitely not &quot;early adopt&quot; wifi 802.11ah whenever it appears..
