Wifi 802.11n- Max Speed 144Mbps in 2.4Ghz

Hello,

I am using apple mac pro m3. I have a modem which supports 300Mbps with 802.11n, only 2.4Ghz.

When I am connecting this modem via mac Wifi, I see max speed is 144Mbps.

I made a test with windows machine which have 2x2 802.11Ac antennas, I saw 300Mbps properly.

I am using channel 6 for this test. Do you know any information about this problem? for example, how many anntennas exist on mac? or which restriction can cause this problem?

thank you

MacBook Pro 16″, macOS 15.3

Actually, 802.11n supports 2.4Ghz and 5Ghz.

Also, my modem supports 802.11n, not support ac (newer). I am sure that windows is connected by 2.4Ghz with 802.11.n

I already said modem does not support 5Ghz.

if your modem does not support 5 GHZ, then that 144 is already the fastest you can run under those conditions.
