The good news is that the interoperability problem between minstrel_ht and carl9170 was discovered and fixed back in February already [the mainline is not affected]. If you know how to apply patches and compile drivers, then you can easily fix it yourself by applying the following patch: "carl9170: fix frame drop and WARN due to minstrel_ht change" <https://patchwork.kernel.org/patch/2174121/> and compile the new carl9170 module. Regards, Christian BTW: I assume you are also running some version of openwrt. Is this correct? Can you tell me which one? Since if this affects a stable release, we should notify the OpenWRT folks, so they can take action. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
