iwlwifi not working properly with 5.6.3

iwlwifi not working properly with 5.6.3

[Ivan Stankovic]

[-- Attachment #1: Type: text/plain, Size: 761 bytes --]

Hello,

I've just upgraded to 5.6.3 hoping that the iwlwifi issue I've been
seeing is fixed, however, that is not the case. The driver manages to
associate and at first all seems well, but it quickly runs into trouble
and my wifi becomes terribly slow, basically unusable.

The device:

  Intel Corporation Wireless 8265 / 8275 [8086:24fd] (rev 78).

I've been seeing the message

    BIOS contains WGDS but no WRDS

(please see attached log for details) similar to what others had
reported, but it does not seem like the recent fixes helped with my
issue.  Do you know what might be causing this?
