Why my ERA 100 just can't detect my 5G WIFI?

My router is LINKSYS WRT1900ACS. It broadcasts 2.4G and 5G in different SSID. But the 5G SSID never shows up in the ERA 100 WIFI connection list. My ERA 100 works well with 2.4G, but it can't detect my 5G WIFI, and can't get connected by manually input.

My other devices, ipad, computer detects and works well with my 5G WIFI.

What channel is your 5 GHz network on? Try changing it to something in the 36-64 range as a test.

What type of 5Ghz signal? Does it conform with the Sonos Network Requirements ?

Important to note, there is a difference between 5G and 5Ghz.

I think it conforms.

In the router settings, the 5GHz band has many options: 802.11a only, 802.11ac only, 802.11a/n only, Mixed(default).

I leave it as Mixed(default).

ERA 100 is my only device can’t find the 5G WIFI.

Does the network name use any special characters that Sonos won’t recognise?

No, I only use normal letters in SSID and password.

OMG, thank u so much!

Changing the channel from "Auto" to "64 - 5320MHz", solves my problem. The 5G SSID shows up and works well with my ERA 100 now. Though I don't know why channel setting is so important to SONOS. I've never changed it before.

I don't know why channel setting is so important to SONOS.

It isn’t. My system’s currently working on channel 112 (5560 MHz).

Maybe your router is a bit quirky.

Maybe your router is a bit quirky.

Allowed Wifi frequencies vary by location, so maybe the OPs router is set for one country and the Sonos gear for another? Or maybe it is trying 6GHz? OP doesn’t list their location.

5 GHz can be tricky with the optional DFS (weather radar) channels being out of your control if a radar is seen.

The channels allowed in each country also impacts 2.4 GHz.

Might just have been removing the Auto channel switching, that can confuse some devices.

I often recommend going back to the original 5 and 2.4 GHz channels to see if that works. If it does then try others knowing your hardware is working properly at the oldest channel settings.
