I have a 2013 MacBook Air (2013) [11ac] which started to play up as regards wi-fi. I think I tried everything I could find on the net. So decided to purchase a TP-LINK Archer T3U Wireless Adaptor, which is dual band.

 

Installed OK but I had 2 SSID'S (say ABC [2.4 & 5GHz] and ABC24 [2.4GHz]). The Air would connect to ABC but at 2.4GHz. Again, I tried several things gleamed from the net.

 

So I set up a brand new SSID (say ABC5). The TP-LINK will not show ABC5 and when I installed the TP-LINK on my HP Laptop (11n) it would not show ABC5 either.

 

But the ABC5 SSID does show up on an Intel NUC [11ac] and a Dell Laptop [11ac] and I can connect successfully. Note: Not using the TP-LINK.

 

My question is, if I am using the TP-Link for wireless, why will it not show ABC5?

Probably set to to a different country where that frequency isn't supported so it won't be visible.

I've also seen adaptors where they couldn't even be bothered doing proper country support, so they only support the 'universal' U-NII Low/Mid (36-64) channels - try setting your AP to fixed channel 36 on 5ghz and see if the 5ghz ssid becomes visible.

I somehow fixed this earlier this morning but couldn't get access to Geekzone to report back.

 

I don't know exactly how I did it, but:

 

1) The TP-LINK wireless utility is pretty basic, but it did allow me to manually set the SSID to ABC5.

 

2) Before or after, I had been looking at the 5GHz channel and it was on 149 (Auto Setting). Note: 3 GWN7610, 1 wired, 2 mesh

 

I tried changing it to 153 on the wired AP thinking it would change all the AP's which caused a reboot but didn't change.

 

Note: Their brief help says 'Select the best channel for Wi-Fi traffic, based on the bandwidth required (80, 40 or 20 MHz) and band (2.4 or 5 GHz). If this AP uses wireless mesh for connection, the channel setting does not take effect.'.

 

So I set the setting back to Auto, which caused another reboot.

 

Soon after, I could see the ABC5 SSID on the MAC and on Windows 10.

 

Until the last post, I had not noticed that the 5GHz channel has moved to 36.
