[Bug 1188400] Re: Wifi channels 12 and 13 unusable
Okay, i get confirmation by intel that the card is a MOW1 that is hardware crippled to 11 channel (US only). For europe there is a MOW2 model available. Bought the wrong card, the bug can be closed.

[Bug 1188400] Re: Wifi channels 12 and 13 unusable
I was expecting the channels to show up in this list as disabled, but looking at the code again I see that they won't show up in your channel list at all if the ROM says the channel isn't valid. There's probably nothing we can do aside from enabling some extra debug output to verify my assertion. If you know how to build kernels and want to try this yourself, enable CONFIG_IWLEGACY_DEBUG in the kernel config, build, then boot with iwl4965.debug=0x40. After booting, search dmesg for the string No traffic (without the quotes). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1188400 Title: Wifi channels 12 and 13 unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1188400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1188400] Re: Wifi channels 12 and 13 unusable
For your device the list of usable channels is read from a ROM in the hardware. It seems likely that your hardware is not claiming support for channels 13 and 14. I don't know why would be the case. Please add the output from running 'iw phy0 info' to this bug. This should allow me to confirm that the channels are supported by the driver but disabled by the hardware. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1188400 Title: Wifi channels 12 and 13 unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1188400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
