5GHz does not show up in the WiFi networks lists of any devices

5GHz band SSID does not show up in the WiFi networks lists of any devices. I tried restart router,reset to factory settings but no luck.

[alius]

Never had a problem with bt router.

Then devices are 2.4 GHz band only.

Hi, 

Is it activated on the router under the settings? 

Are you close enough to the router? 

Thanks,

[alius]

Yes is activated on settings and I'm close enough to router. I can find
5GHz WiFi on my bt router when I tested.

Hi @alius,

Welcome to the EE Community.

What type of devices are you trying to connect? 

Have you checked they are 5GHz compatible?

Is it a Bright Box 2 router?

Thanks

James

[alius]

Yes it is bright box 2 router,3 android phones and tablet can't find 5GHz WiFi, was no problems with previous router.

Do the router's 2.4 GHz & 5 GHz bands have distinct SSIDs? By default Brightbox 5 GHz SSiDs are prefix by "5GHz-" . I've heard that BT HHs use the same SSID for both bands & some devices have trouble with that.

Can't see image. Can't you just say "Yes" or "No"?

[alius]

Yes

I notice 1 discrepancy:

My 5 GHz Mode is also A+N+AC but Above & Bandwidth are greyed out & I can't get them to show.

Update: this morning my phone found 5GHz singal,but unfortunately it's gone again after few minutes. I think router is faulty it self.

[XRaySpeX]

Sounds likely. Phone CS & ask for a replacement, cuz it don't work on 5 GHz band.
