Wifi Issues with Brand New MacBook Pro M3 Pro chip

I have recently got myself a MacBook Pro 16 with M3 Pro chip for work. I have had this machine for just over a month, and have started to have WiFi issues in the past few days. I originally thought it was everybody, but asking multiple of my coworkers, no one has a similar issue. Even I do not have a similar issue on my iPhone.

I read all the discussions in below thread, and tried the semi-solutions presented. None are working for me. The connection is so slow that prevents me from doing my work. This happens especially when I am in the office of ~20 people, but also when I am at home.

As mentioned multiple times in the above thread, this is OBVIOUSLY a problem with the MacBook M3, whether software or hardware problem. No other device on the same network is experiencing a similar issue, and multiple of these are Macs as well.

Per our company requirements, we have the below filter/proxy installed on all our machines. I am unable to disable it right now, but can ask to see if I can test without. Not sure if this can cause any issues at all or not.

I am hoping to find a solution to this, as this is basically preventing me from doing my work as usual.

Thanks for any insight or suggestions in advance.

The first troubleshooting step would be to disable/uninstall all third party apps that claim to protect, manage, clean, boost performance, etc. Such apps interfere with the Mac's built-in security and data management. Sophos would be an example of such an app.

Sophos is a Windows-on Intel anti-virus product. You Mac does not have the same processor. it is nonsense to be using a product that looks for antique Windows viruses that can not possibly infect your Apple-Silicon based Mac.

Tell the gestapo IT department you will use MalwareBytes, thank you. (Then only run it on demand.)

If they are demanding a VPN for ordinary home use, they are really out of touch with reality.

you have a strong raw signal RSSI at -40. You must be very close to your Router, your noise measurement of -97 is very low and suggest you do not have another Router anywhere near channel 153 using anything overlapping your 40 MHz channel.

Using your older Router's 802.11ac rules, the maximum possible speed attainable there is 400, using both antennas, but you are FAR short of that at only 135. For some unknown reason, you are only using only ONE antenna.

It is conceivable, but not likely, that you have a disconnected antenna wire.

if you has a 802.11ax Router, maximum possible would increase slightly to around 287 M bits/sec with one antenna, two antennas yields 573 M bits/sec.

in the same room as your Router suggest you might benefit from a Gigabit Ethernet cable connection:
