Red Hat Bugzilla – Bug 448242
iwl4965 does not find APs with high frequencies
Last modified: 2008-05-29 14:56:03 EDT
Description of problem:
Wireless Chip does not detect an AP when channel is higher than 11, 9 works fine.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. make AP use channel 12
2. iwlist scanning
AP not listed
AP in list
This seems to occur on an iwl3945 with ubuntu 8.04 too.
The cfg80211 component is defaulting to settings for the US regulatory domain.
Channels 12 and 13 are not available in the US.
Future plans include a much more flexible mechanism for handling regulatory
issues, but currently the only other regulatory domain known to the kernel is
one for Japan. But, it does include channels 12 and 13. You can make those
channels available by adding a line like this to /etc/modprobe.conf:
options cfg80211 ieee80211_regdom="JP"
Please ensure that you are complying with local laws regarding wireless
communications! Does this make those channels available for you?
Thannk you for your answer. This makes this not a bug.
