Good point.  Now tested and seems to work.

But I'd appreciate it if someone else were able to doublecheck my
results.  I am juggling with a number of settings and could easily mess
up something, invalidating the tests.  I believe the issue should be
present in lots of systems, isn't that correct?  Any GM45 based laptop
should do as a test bench, and maybe others too.

The WiFi issues I had also indicates that these changes should be tested
on as many different systems as possible.
