The problem should result from the power saving controlled by firmware.
I'd suggest to disable it by default and re-enable it after firmware fixes
this issue.
BTW. the firmware I tested from linux-firmware git tree is

NACK for this patch. If you were to make this change, you should also change the
text in the MODULE_PARM_DESC() for this parameter. It shows a hard-coded default.
I am not sure this is a firmware problem as some users report that they need to
run with the "ips=0" option, not with "fwlps=0" as your patch would force.
Conversely, the driver works fine as is with other AP/environment combinations.
The Realtek engineer has told me that he is aware of problems with the dynamic
management for all the drivers, and that they are working on major replacements;
however, there is no timetable for the new code.
If we make a change in the default power settings, I would prefer changing
inactiveps and its MODULE_PARM_DESC() text; however, that would have a negative
impact on power usage on the host.
I have BCc'd the Realtek engineer and I hope to get his comments on this change.
