Message-ID: <20091028204321.5dee58ad@bnc.JUSTUS> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ath9k-devel@lists.ath9k.org Hi, I have not been able to compile wireless-testing because of the stlc45xx error I posted. While waiting for a response I decided to do some more testing/checking. I have a laptop with an 11n card in it and running a late kernel. I checked the kernel and found that all the 11n stuff has been turned on and the ATH9K module, see below, seems to be ok too. I forced my router, dlink 655-dir, to go to ch 11 Wireless Radio : Enabled 802.11 Mode : Mixed 802.11n and 802.11g Channel Width : 40MHz Channel : 11 Secondary Channel : 9 WISH : Inactive Wi-Fi Protected Setup : Disabled However, it was still connecting at 11g. The iw list below shows that the MCS only goes to 7 when I thought it should go to 15? Any thoughts?
