The specs page of jolla and intex just mention wlan under connectivity.
wikipedia states that it should operate on the 2.4 and the 5ghz band, referring to the blog post http://www.techuntold.com/mwc-2016-intex-launches-aqua-fish-smartphone-with-sailfish-2-0-os/ where "Wi-Fi 802.11 a/b/g/n," is mentioned.
does anybody actually know if 5GHz should be supported (because right now, it doesn't show the 5 band networks in the gui)

i've investigated this a bit further and according to iw phy (which shows the HW capabilities, no matter if driver supports it, its enabled, ... whatever) the wifi is definitely limited to the 2.4 band.
Frequencies: * 2412 MHz [1] (20.0 dBm) * 2417 MHz [2] (20.0 dBm) * 2422 MHz [3] (20.0 dBm) * 2427 MHz [4] (20.0 dBm) * 2432 MHz [5] (20.0 dBm) * 2437 MHz [6] (20.0 dBm) * 2442 MHz [7] (20.0 dBm) * 2447 MHz [8] (20.0 dBm) * 2452 MHz [9] (20.0 dBm) * 2457 MHz [10] (20.0 dBm) * 2462 MHz [11] (20.0 dBm) * 2467 MHz [12] (19.0 dBm) * 2472 MHz [13] (19.0 dBm) * 2484 MHz [14] (disabled)
-> NO 5GHz WLAN connection
that would mean on the other hand, that no-one at jolla and/or intex found it necessary to point out that the mentioned specs are wrong, during about 6 months?
over here, nobody gets the cross-talk effect, so channels 1, 4,6,8,9,11, ... are used, only chance to eliminate it, is use channel 1 and employ RTS/CTS.
on top, there are still some on b/g killing the possible n performance and improvements ... argh. (of course also on channel 1), so actually 2.4 is doomed here

for full comparability: the diff between the outputs of the both phones, so one can see what are the differences over all possible capabilities.
