Vodafone Booster keeps dropping connection on Mac laptop

Your RSSI signal strength of -41 is excellent, you must be very close to the access point.

You are making a connection using 802.11ac, at 80 MHz channel width, in the 5 GHz band.

Your transmit rate of 867 and MCS index 9 says TWO antennas are being used with the most complex pattern available (256 patterns per signaling interval) using two antennas on an 80 MHz channel.

However, the strength and number of other Routers around you is very high, and likely related to why you are having issues on channel 36, often the default channel.

If you use the entry on that menu to "open Wireless diagnostics". when you click (Continue) it will scan your settings and may make recommendations worth considering.

While that window is open if you choose SCAN from the Window menu,

...it will list the channel assignments of all networks is range, looks like this one:

(drag and drop on Preview to see larger)

What I am fishing for here is ˘ anyone else using any channels near your channel 36, up to and including 48, or a 160 GHz channel up to and including 64?

if you hold down the Option key while you click on the Wi-Fi icon on the menubar you get s snapshot of current wiFi performance like this older one.

when the troubled Mac still has a good connection, capture a screenshot or transcribe the parameters shown and post back here for readers to analyze.

.

that scan has no trace of your previous Booster that was on channel 36. it shows only a more distant router with the same network-name on channel 112.

If you click on the column header for "channel" it will sort by channel number.

Is it possible the Booster is too far away from the base station and is unable to keep its connection? You may have to pull an Ethernet cable to connect it to the Base station, or locate the Booster closer to the base station.

All of those access points in your screenshot are incapable of a wireless connection since they have extremely poor signal strength (RSSI).....I'm surprised you can connect to any of them. The best ones are the two with -72db RSSI and that is still unusable. I have problems with WiFi connections once the RSSI gets to around -60db & -63db. The signal strength should be somewhere between -30db to -55db (with the -30db being the stronger signal).

Vodafone is not an Apple product.

If you're having problems with a 3rd party device, you need to contact its developer. Apple has no responsibility either to or for Vodafone.

Developers who produce products for use with Macs are responsible for making them work with macOS, not the other way around. And only the Mac is using macOS, other devices are using other operating system so saying they all work is not really giving added information pertinent to the issue you're having.

this one is a bit more recent

Note the last line in the left box, "Best 5 GHz channel"
