Product: Pavilion 17-ab077nz
Operating System: Microsoft Windows 10 (64-bit)

Do newer notebooks (sold in Switzerland, as far as that matters) talk 5 GHz WiFi only? I am looking for a new notebook. Half a year ago, I saw an ENVY 17-r187nz with 802.11a/b/g/n/ac, but now the specification of a Pavilion 17-ab077nz (that looks otherwise almost identical) talks only about 802.11ac.  Other new models also offer 802.11ac only. Do newer notebooks indeed no longer provide 2.4 GHz Wifi capabilities? Having high speed at home is great, but I am afraid that, while travelling, 5 GHz networks might not always be available.

802.11ac only works in the 5 ghz band but 802.11ac compliant radios will fall back to 802.11n and 2.4 ghz if 5 ghz is not available.

I have owned several 802.11ac laptops and never had a problem connecting at airports, Starbucks, etc. And they tend to broadcast only on the 2.4 ghz band or have both 2.4 and 5 ghz.

I ended up buying a Pavilion 15-bc057nz, for which the specification also mentioned 802.11ac only. I can now confirm that it falls not only back to 802.11n if necessary, but that it also switches to 2.4 GHz if a 5 GHz network is not available.
