SSID best practices naming conventions

The network drops are unrelated to the SSID names chosen.

I usually run the same SSID on all three bands, and use band steering to get the clients where I want. Not the SSID. But what features are available depends on the Wi-Fi gear involved, and ISP-provided Wi-Fi gear will usually be optimized for low cost and ease of support, and features are third or forth on the product priority list.

How is it working now? On Mac, the basic Wi-Fi environment characteristics are visible when using Option-Click on the Wi-Fi logo 🛜 in the menu bar to capture some Wi-Fi network data.

For us to look at the Wi-Fi network data here, post the items shown in the following image including the Security mode and from Channel to NSS inclusive (Security, Channel, Country, RSSI, Noise, Tx Rate, PHY mode, MCS, NSS, green highlight) (without posting the Wi-Fi address, any local HotSpots that might be present, the network name, or the BSSID, all of which are expurgated from the image shown below, red highlight), and we can take a look at the basic network environment.

Tools such as the third-party WiFi Explorer app for macOS can be used to get a better view of the environment.

Your particular Wi-Fi gear might also have some embedded monitoring capabilities.

What you name it makes absolutely no difference.

There are however some advantages and disadvantages to splitting a dual band network rather than combining them as you have. I have mine split (one SSID for the 2.4 band and a different one for the 5GHz band) so that I can control which devices are connecting to which band.

Following is one article that has some information about that: https://5gstore.com/blog/2024/11/07/dual-band-wifi-to-maximize-network/

Your signal-to-noise (SNR) is in the weeds (at ~11), and the transmit rate is thus unsurprisingly also low.

SNR below ~15 tends to be wobbly and slow.

Are you either distant from the Wi-Fi router, or with walls or other blocks interposed? Or is the Wi-Fi router nearby?
