HTC ONE (M7) not finding 5ghz wifi

[Sheikh Haroon Akram]

Please suggest me what should i do to fix this issue
my M7 connects to 2.5ghz perfectly but can't search 5ghz
i have unchecked wifi optimization but still the issue prevails

Try going in to WiFi settings, then click the 3 vertical dots to get into your menu, then select Advanced, then select WiFi Frequency Band, From there you have Auto, 5Ghz Only or 2.4Ghz only. If its set to Auto it should pick up 5, but since your specifically trying to get 5 put it on 5 and see if it works.

IF it were my unit the next thing i would try is to clear the system cache.
You have to go into recovery to do it. I think with the unit off its Power button and volume down key, actually i would google it. There are many good places, here included with much better instructions for wiping cache.
Also, go into settings, battery, and make sure fastboot is unchecked.
