The 3.2.6-3..kernel update

FYI whoever may be concerned.

This mornings update to 3.2.6 included various things but it still hoses my wireless. All kernels after 3.2.3-2 cause wireless network failure (but wired still OK)
IANAE but this may be assocaited with kmod-wl which also updated this morning.
Anyway, I can sit on 3.2.3-2 for a while but it can cause conflicts in yum if it goes on too long.
Anyone know a fix which would allow me to stay upto date?

Brian

I also have the same symptom:

My lspci:
....
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8187SE Wireless LAN Controller (rev 22)
....

iwconfig on 3.2.2:
wlan0 802.11b/g link ESSID:"xxxxxxxx"
Mode:Managed Frequency=2.462 GHz Access Point: 48:5B:39:0E:5C:03
Bit Rate=54 Mb/s
Retry:on RTS thr:off Fragment thr:off
Power Management:off
Link Quality=70/100 Signal level=-46 dBm Noise level=-99 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

iwconfig on 3.2.6:
wlan0 802.11b/g Mode:Managed Access Point: Not-Associated
Bit Rate:11 Mb/s
Retry:on RTS thr:off Fragment thr:off
Power Management timeout:0us mode:All packets received
Link Quality=0/100 Signal level=0 dBm Noise level=0 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

I use kmod-staging from RPMFusion for wireless support

Re: The 3.2.6-3..kernel update

Strange, the wireless problem was solved for me in 3.2.5 already, I'm posting this from 3.2.6-3.fc16.x86_64 using a Canyon card:

Code:
01:07.0 Network controller: Ralink corp. RT2561/RT61 802.11g PCI
The only strange thing I've noticed since upgrading to 16 (from 14) is that I invariably have to suspend after a reboot before WLAN authentication will complete, subsquent wake-ups from suspend are fine.

in a newly updated kernel version 3.2.7.
No good

Re: The 3.2.6-3..kernel update

OK.
I looked into dmesg output and found:

I really can't help with the 8187SE but with the 8191SE support with the driver has been in the kernel package so no need for the kmod-wl...This has been from the end of f15 to date.

Re: The 3.2.6-3..kernel update

the main Fedora quirk I've seen on my laptop is that sometimes it will not see access points until I run "iwlist wlan0 scanning". That is, until I force the network to scan for access points on the wireless interface. After that NetworkManager works fine and the configured one connects.
I don't see that happening recently though--> UPDATE I saw this happen at work yesterday

Re: The 3.2.6-3..kernel update

OK. I decided to continue investigation.
On 3.2.9-2 PAE I did:

Quote:
[root@localhost ~]# iwconfig
em1 no wireless extensions.

lo no wireless extensions.

wlan0 802.11b/g Mode:Managed Access Point: Not-Associated
Bit Rate:11 Mb/s
Retry:on RTS thr:off Fragment thr:off
Encryption key:off
Power Management timeout:0us mode:All packets received
Link Quality=0/100 Signal level=0 dBm Noise level=0 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

[root@localhost ~]# iwlist wlan0 scan
wlan0 Failed to read scan data : Operation not permitted

[root@localhost ~]# uname -r
3.2.9-2.fc16.i686.PAE
still the same simptom.
One more question - how can I install and continue to use version 3.2.2 of kernel? It worked ok but it disappeared from grub menu?

You have to make sure the value of "installonly_limit" in your /etc/yum.conf file is large enough so the installed kernel doesn't push out an older kernel that you want to keep. If 3.2.2 actually disappeared, that probably means it was the oldest one and your installing 3.2.9-2 PAE pushed 3.2.2 out of your system and it's gone.

you can check with:
Quote:
rpm -q kernel
If 3.2.2 isn't on the list, it's been removed. If you don't mind kernels building up in your /boot area, you disable installonly_limit by setting it to 0

installonly_limit=0

in your /etc/yum.conf file (ref: man yum.conf )

Re: The 3.2.6-3..kernel update

Great! Thanks.
Yes - 3.2.2 is gone.

So the next question - how can I return an old, but still good 3.2.2?

Thanks!
