iwlwifi in kernel 2.6.21-1.3125 (was Re: F7t4 KDE live CD test report)

can you try the kernel from here:

iwlwifi works fine for me using this (and the previous one) the version in the livecd does not even connet to my wpa/wpa2 ap.
but no everything seems to work with it, traffic, ping etc.


The iwlwifi in the kernel from davej is much better, but all is not sweetness and light, at least when running Network Manager. I have attached my observations to this message, but they boil down to two things:

1/ Connection strengths don't seem to be correct.
2/ It is impossible to change wifi networks.

Problems with iwlwifi and NetworkManager in kernel 2.6.21-1.3125.fc7

1/ Connection strengths are all maximum.

   I currently see three wifi networks.  All are showing maximum
   connection strength.  Normally in my current location two would be
   about 75% and one about 40%.

2/ Can't change wifi networks.

Connected to a WPA network, using Network Manager to switch to an open network:

Sucess.

It appears that any attempt to switch to a different wireless network
will fail, but that switching to a wired network and then back to the
same wireless network does work.
