iMac Pro iMac Pro wifi only connects at 54 mbps speed

[duman]

Hi

I have just got my iMac. I have both Google Wifi and Apple extreme. My iMac wifi can only connect at speed 54mnps to both devices. iMac and other devices are in the same room. Did anyone face the same problem here? Or do you think it is broken?

EDIT:
Added screenshot...!

Thanks
-D

Ah that's great! Thank you very much indeed...

Bit of a thread revival - but just unpacked a new 2018 Mac mini, and seeing the same thing with wifi. All other Macs connect at 1300Mbps, but for some reason the new Mac mini is showing 54Mbps:

Very odd - or I guess must be a bug as quick speed test shows that it's saturating the 120Mbps internet connection.

And in the wifi info from the menu bar, it does show a transmit rate of 975Mbps. Kind of crazy that Network Utility isn't a reliable method to quickly check network speed.

Edit: just trying to copy a large file across the network, definitely too slow considering it's coming from a source that is connected with ethernet and SSD.

Well I guess it depends on how much you are paying for. Here Down Under you can purchase at 12Mb/ps, 25Mb/ps, 50Mb/ps or 100Mb/ps.

Same thing happened to me. My older gear enjoyed gbit wifi but a new 2018 Mac saw only 54mbps speeds. What?! I eventually learned the solution was simple: TKIP wifi encryption was to blame!

In my wifi router settings, I needed to use only WPA2 with AES security.

WPA2-PSK [AES] = 1300 mbps!!
WPA-PSK [TKIP] + WPA2-PSK [AES] = 54 mbps

Checking on whether this was safe (search: tkip vs aes), I learned TKIP is deprecated. Hope this helps others...

You are my new best friend I never would have thought of this-- it worked like a charm. Thank You!

Until it didn't. Initially, as mentioned, this was the solution. But the MacBook Air wifi link speed has gone down to 54 Mbit/s again. Confirmed that the encryption was correct, restarted laptop, rebooted AP all to no avail.

Reading all the threads I can find, I'm leaning toward glitch in OS (Mojave, updated to 10.14.6) but I'm clues how to solve this and solve it I must.

So help. Please.
