MacBook Pro dropping connection to Vodafone boosters!

Hold down the Option key while you click on the Wi-Fi icon on the menubar to open up the tools for investigating and fixing Wi-Fi issues

First is "Open Wireless diagnostics", which opens the wireless diagnostics Assistant, but does not proceed.

There are about eight different things you can do from here, but the top-level is to choose Diagnostics off the Window menu, or simply click continue, to do a quick check for Gross misconfiguration or operating problems. Your Admin password will be required. If any recommendations are shown, you should consider then seriously.

Next is to hold down the Option key and click the Wi-Fi icon as before. The screen that opens shows operating parameters of your network. Screenshot, transcribe, or photograph the results and post back in a reply on the forums. Looks like this older one.

The usual way we do this with ONE Router and No boosters is the set the Router to "automatic" channel selection. Then when the Router powers up, it listens momentarily to what is already on the air, and adjusts to the least-busy channel.

it is not an accident that every debugging procedure starts with "cycle the power to your Router."

The next level we can use is to use the SCAN tool in Wireless Diagnostics to look around at what is visible over the air around the Mac. This has the advantage of showing what is seen at the Mac, which may be slightly different than what is seen at the Router(s).

this is what it looks like:

Click on the channel column to sort by channel. This tells you the nominal channel in use, but every channel also spreads up and down the channel numbers, depending in its channel width. For example, channel 36 at 80 MHz wide spreads to engulf everything up to channel 48. You may need to look up the spectrum spread with some tables, available online.

On my network, is am located "in the woods", far from neighbors' Routers. So everything I can see is my own gear. But my house is solid masonry construction and has wire-lath in the walls, so every section is a Wi-FI dead zone. I have to use multiple Access Points just to cover the house and garage.

There is another more comprehensive but quite inexpensive tool you may want to try, which make everything simpler. It is WiFi Explorer. its Spectrum display looks like this:

...

The first thing we look at is raw signal, RSSI. it is presented on a logarithmic scale where numbers as high as -30 are right next to your Router, and numbers as low as -70 are on the verge of disconnecting for bad signal. At the moment you sampled yours, they register as not bad in either case. In large offices with multiple Router coverage, Network Admins try to attain at least -65 from at least one source at all times.

Next we glance at Noise, measured on the same scale, to see if there is any information there. Mine is as low as -95. Yours both show some possible interference at -92 on a logarithmic scale, but those numbers are not in themselves egregious.

from your booster, MCS 7 and NSS 2 says you are able to make a connection using two antennas, using 64 patterns per signaling interval, to obtain a steady transmit rate of 585 M bits/sec.

from your main Router, MCS 9 and NSS 2 says you are able to make a connection using two antennas, using 256 patterns per signaling interval, to obtain a steady transmit rate of 867 M bits/sec.

I see no explanation YET for the disconnections from the Booster.

Next thing to examine is whether other Routers are interfering with your Router or Booster.

on channel 64, you have an obvious clash with TCAP73BBE1, with signal level of -74. That is just slightly lower than you could connect to reliably, but more than enough to interfere with your signal on channel the Same channel 64.

on Your channel 36, you have a less obvious but very real conflict with TALKTALK489D2D1F on channel 48. Your nominal channels are not the same, but the Spectrum overlaps. The moment you both send data, it will collide. Their signal level is much lower at -84, but still high enough to interfere.

Your other base station using channel 100 is clear of conflicting networks, and has a signal level of -59. Is there a reason you did you not connect to that one?

<< 36 usually causes issues. Not sure on 48 >>

at 80 MHz those are the SAME channel, because of spread.

in the old days, we learned to manipulate 'which access point you connect' to by giving each a different name,. then log in to each at some time. When you want a make particular connection, just choose a specific name.

if the Vodaphone access points are not flexible enough to solve your problems, don't use them. Just use another brand of Router with DHCP-dispensing turned off. That's what I do, and it works fine.
