I just set up a brand new MBP M1pro 14 inch and it will only connect to my router when in the same room. On all of my other devices (inc 2012 MBP) the router maintains connection across the apartment on 2.4Ghz and mostly on 5Ghz. On this new device I can't leave the room with 5Ghz and 2.4Ghz drops from my top speed on 120mbs to 10mbs in the next room!! I have reset the MacBook but this has not helped. PLEASE HELP!

these can interfere with regular network operation.
If you are using a VPN you installed on your own, remove it while continuing to debug.

If this VPN is for an Institutional/Corporate connection, contact your institution for additional guidance.
80Mhz channels:
If your 5GHz band is configured (on your Router) to 80MHz channel-width, some users have reported problems. If they reconfigured the 5GHZ band to back to 40MHz channels, many of their connection and speed problems evaporated.
Network Location:
If you continue to have trouble after using these steps, create a new named Network "Location" -- a collection of settings applied "all at once" when you select it. Every new named "Location" you create starts with all defaults, which lets you walk away from any errant settings that might be causing you trouble:

Hold down the Option key while you click on the Wi-Fi Icon on the menubar. You get a snapshot of the current conditions, similar to this older one, transcribe or screenshot your snapshot and readers can advise:
There are some tools in MacOS that can help you see what channels around you are currently in use. They are accessed by holding the Option key while clicking the Wi-Fi icon on the menubar, then choosing "network diagnostics". they include:
1) Assistant
2) Info
3) Logs
4) Scan
5) Performance
6) Sniffer
Scan looks like this:

I know there's nothing bad showing up there. That's why I'm asking the question. none of this makes sense to me. It is behaving like I've wrapped my MacBook in tin foil or something? Attached are screenshots showing the 5ghz channel wifi at 5m away and then again at 6m away, but behind a plasterboard wall. Behind which I normally get perfect signal on other devices. Channel selection all set to auto.
I have tried all of those things and nothing helps. The machine was literally new out the box today and the internet has always been bad. I literally have the two macs next to each other now and my old one is perfectly fine. Wifi diagnostics doesnt pick anything up.. Its as if the aerial in the new macbook just isnt very strong at all? Is it possible that it has broken in someway?
wait, that's in the same room? that RSSI (raw signal) is awful!
close to your Router you should be getting around -50, or slightly closer to zero. As you go father away, that number is expected to drop off,
When it reaches -65, your Mac or iPhone will actively try to switch to any other network in range.
Wherever that is, you are already too far from your Router for a good connection.
Yes sorry. That’s confused things. I am currently in a different room testing it. The signal strength shown there is the same as it is on my other devices in this same room. Not ideal but it works. The real problem is the TX rate I think? The problem is regardless of the signal strength, when I do a speed test it is very jittery and very slow. Whilst the other devices do not have this issue. I can barely load a video on the new MacBook, but my old one is fine.
I have seen a few things on other forums about M1 Pro connectivity issues, but these seem minor in comparison to total falloff as I’m experiencing… there’s minimal interference in my flat. I’ve power cycled the router and played with the Chanel’s and bands, completely reset the computer. Honestly no clue how to proceed.
You asked about maybe broken antennas. The test for that is to walk your MacBook in next the the Router and look at RSSI. you need to be getting between -40 and -50 right next to your Router, and if you are not, your antennas are disconnected or broken.
You mentioned your apartment. In an apartment building, the main enemy is too many other Routers around you. The defensive solution is to NARROW your data channels to the minimum, in hopes of Not getting your signal stepped on by your neighbors. an 80 MHz channel over which you get 1 M bits/sec is not a win.
I was at my local Apple store, and discovered it was completely saturated your different Routers, each on a very narrow channel. Reception was great, throughput was just fine. I except if I moved too far in any direction, it would just "roam" to another Router on another channel.
-70 is really not enough raw signal. There is no point trying to micro-analyze other factors. You are 5dB worse that "ready to spontaneously disconnect". If your other devices are getting by, that is fairly miraculous.
You need to look at some different solutions such as relocating your Router, adding an additional access point, running some Ethernet cables, or using a powerline Router or Switch.
So i do understand poor signal will affect connection. But the 'speed' remains consistent on my old macbook even with poor signal, until it becomes so poor that it drops out. The difference is the new one sees to drop out as soon as the signal becomes even slightly less than perfect. Standing next to the router it works, but 5m away with a direct line of site, the 5ghz drops...
Weirdly, I changed the 2.4ghz mode from auto (b/g/n/ax) to just (b/g/n/) and this channel is now twice as fast when at the sme distance... 5ghz still wont work... Also its a London flat with 3 apartments next to it, the radio interference from other flats is minor...
Set to 802.11n and using the 2.4GHz band, 144 M bits/sec is as fast as you can go, using two antennas and 64-patterns per signaling interval. Your hardware appears to be working under these circumstances.
Anything faster requires the 5GHz band and a more advanced scheme such as 802.11ac or ax, which you said you have turned off.
Many users prefer to tune 'which band' they connect to under different circumstances. This can be accomplished by giving the different bands slightly different names, and connecting to the name you like better for a certain situation. (The router immediately merges them back into the same network for most purposes).
yes sure. but I only turned off ac/ax because it was WORSE with them on! AND I only used the 2.4ghz band because its also WORSE when connected to the 5ghz band. Which fine at super close range but when I sit 5m away, it completely drops out... My router is supplied by G.Network here in London. It is FTTP and should be at 140mbps download. It is on all my other devices when connected to 5ghz band. The router is a Nokia, shown here: https://www.youtube.com/watch?v=qO4hjx1Q3us
I do appreciate your help here, but its not done no. as I say, I have multiple apple devices and Macs connected to the 5ghz band no problem. I would like to use it on my new one (obviously faster) but it doesnt work? How is this done?
Many users prefer to tune 'which band' they connect to under different circumstances.
This can be accomplished on the Router by giving the different 2.4 and 5GHz bands slightly different names. it is incredibly common the see MyRouter and MyRouter_5G anywhere you go. (where MyRouter is your network-name of choice).
Then connect to the name you like better for a certain situation. (The router immediately merges them back into the same network internally for most purposes).
Then re-enable the advanced features and post an Option-Wi-Fi snapshot of the result.
