Hello,
I'm new to the list, and have one question, apologies if this not
appropriate for this list.
I have recently updated a Lenovo T410s to opensuse 12.3, and noted that the
PC will no longer connect HT to anything.
It connects fine at both 802.11a and 802.11g, but never with HT.
throughout is ~30Mbps, both AP and card list the connection at 54Mbps
This worked before the update from opensuse 12.2 and the older
kernel/iwlwifi driver, using
5Ghz HT at throughput at 90Mbps
I see these messages in the debug, regardless of which band or channel
is used:
2013-04-30T21:33:02.853629+02:00 lamda kernel: [ 6355.226711] iwlwifi
0000:03:00.0: I is_lq_table_valid Channel 48 is not an HT channel
This event occurs in 802.11g and 802.11a bands, and on a variety of APs,
channels.
At the same moment a number of different clients are happily using HT on
the same channel and AP.
I read through some of the related patch, but not being a coder, was not
able to answer tihs question:
What is the driver detecting that tells it this is not an HT channel ?
hints very much appreciated.
Best regards,
