----------
Please post full dmesg output for both 4.14 and 5.4 kernels.

This is probably the same problem as reported in FS#3093. I also noticed this on Netgear R6220 but unfortunately it has not magically disappeared...

In my case adding a short 25ms delay in mt7621-pci driver has helped. This is still much shorter than in old 4.14 driver (100ms with one 50ms exception) but seems to solve the issue. 

Try applying attached patch and check if that helps.
