Comment 1 John W. Linville 2009-12-29 15:05:30 UTC 
Luis, did you ever setup a bugzilla account for that ath9k-devel list?

So, looks like this stanza in ath9k_process_rate is returning a rate index > 76?

        if (rx_stats->rs_rate & 0x80) {
                /* HT rate */
                rxs->flag |= RX_FLAG_HT;
                if (rx_stats->rs_flags & ATH9K_RX_2040)
                        rxs->flag |= RX_FLAG_40MHZ;
                if (rx_stats->rs_flags & ATH9K_RX_GI)
                        rxs->flag |= RX_FLAG_SHORT_GI;
                return rx_stats->rs_rate & 0x7f;
        }

Comment 3 John W. Linville 2010-09-13 17:28:13 UTC 
ath9k guys, ping?
Comment 4 vasanth 2010-09-14 13:27:49 UTC 
Created attachment 29972 [details]
debug patch to dump rx desc status
Comment 5 vasanth 2010-09-14 13:28:42 UTC 
Nikil, what is hw being used, lspci output?. Also by any chance is it possible  to get some dmesg output with the attached diff?. You can probably use latest stable compat-wireless (http://wireless.kernel.org/en/users/Download/stable/) for debug log.
Comment 6 Nikhil Sethi 2010-09-14 21:32:53 UTC 
My wireless card is TP-Link TL-WN861N, (http://www.tp-link.com/products/productDetails.asp?pmodel=TL-WN861N).

System is a AMD Geode based system http://www.soekris.com/net5501.htm

Yes, I can run with the above patch, probably tonight, will report back with output.
