windows 10 doesn't see 5ghz wifi - super frustrating

5GHz
FCC :  Band 1 (CH36, CH40, CH44, CH48) ; Band 4 (CH149, CH153, CH157, CH161, CH165)
CE : Band 1 (CH36, CH40, CH44, CH48)

So it doesn't support the channels yout router is currently set to, you probably want to set the channel manually to one it supports.

Hi all,

I bought the Edimax AC1750 EW-7833UAC wireless adapter, and as far as I can tell, it's supposed to support 5ghz wifi.

Also, I KNOW my router supports it, see attached what it says in it's login page - "wifi mode: a / n / ac"

No matter what I do, I can't get the adapter to see the signal.

I tried going to device manager -> network adapter -> my edimax adapter -> proprties -> advanced -> wireless, and then tried all options that were there:

IEEE 802.11a

IEEE 802.11a/n

IEEE 802.11a/n/ac

IEEE 802.11ac

IEEE 802.11b

IEEE 802.11b/g

IEEE 802.11b/g/n

and it still can't find it. I'm not a networking expert and I thought that there would be no problem for this adapter to work with my router. Was I wrong? Are they not compatible?

And if they are, what could possible be the problem? :(

from which category should I select? for dummies (like me) I mean - from which paranthesis group? (FCC Band1? FCC Band 4? CE Band 1?)

Just look at the numbers and choose one on the router that is in either list. Which ones the router will let you select depends on your country/region.

you're a life saver!!!!!

I spent so much time on this.......I changed the channel to 36 because no other was available from the list and it instantly appeared.

Thanks so much!!!!

 

Do the channels matter though? Am I losing/gaining speed?

Channels are to separate Wi-Fi broadcasts so interference from other networks is reduced. This matters mostly for 2.4GHz Wi-Fi where lots of networks broadcast on the same channels. Picking the least congested channel will improve speed. For 5GHz, the range is usually too limited to really have any issues with interference and congestion.
