wifi speed decreases
-
Device gets Tx Rate over 900 Mbps upon connection to the router then the speed gradually falls down to 15-30 Mbps within couple of hours. 5 GHz connection, device is within 1 meter from the router. Happens only to 2018 MacBook Pro, all other devices on the network seem to be working just fine.

@ilja-vinogradov @Hreiðar-Kristinn-Hreiðarsson Can you guys please generate support files for us to research this more? Generate them from the main router after the performance drop happens. Reference this community post in the email please.

I have a 2018 MacBook Pro and have seen a stark increase in connection and speed. My 802.11AC connection was showing a TX rate of 975Mbps before the upgrade and 1170Mbps after. However, the A-MSDU on the portal did slow the speed and I unchecked it and the speed came back. I also set the 5GHz channel manually. When I set it to automatic, the signal strength to the mesh points drop by around 20%. So far I am very pleased with this upgrade!
