Hello,
I'm using a TL-WR1043ND v3 with OpenWrt. I've had a lot of issues with the connection slowly deteriorating over the course of 20-72 hours until it became completely unusable and I had to restart the router. This issue has been documented many times (https://bugzilla.kernel.org/show_bug.cgi?id=42877), and I was eventually able to find what seems to be a long term solution by both disabling the hardware ACK and the adaptive noise immunity. A seemingly unrelated issue is that the switch LAN-LAN speed seems to be crippled as measured by iperf between router and a client (seems like the same issue: https://bugs.openwrt.org/index.php?do=details&task_id=891). This is still unresolved.
I'm wondering if more knowledgeable people could tell me if this "device wlan0 left promiscuous mode"
and the following "disabled" and "blocked" states happening after 36 days of uptime could somehow be related to the issues mentioned above, or if they could be the symptoms of another problem.
Thanks a lot!
