Sun Aug 7 20:39:51 2022 hostapd: wlan1: STA 1c:53:f9:1f:54:4b WPA: pairwise key handshake completed (RSN) I have compiled OpenWrt with ath9k debugging enabled, but I do not quite know what to look for.After reboot with correct 2.4GHz WiFi settings (WPA2-PSK, auto cipher, ch.10, WMM OFF): all Feit smart plugs receive IP addresses and work, but many other more advanced devices don't get IP addresses assigned, like Google Nest Hub.

run hostapd on the PC and wpa_supplicant on the TP-Link device. The problems persist if I swap the server and client, i.e. The only relevant parameter (apart from using a bridge) varied on the client was 4addr on/off. The only parameters varied on the AP when taking the measurements were 'option wmm' and 'option wds'.

In that case the 4addr mode makes no difference. The use of the 4addr mode reduces the throughput by more than 90% compared to an identical setup without 4addr mode, unless I limit myself to 802.11g. In contrast, when the same two machines are configured as 'ordinary' AP and client (4addr off) the speeds are as follows: Measuring using iperf between the AP and the client, I get: If WMM is enabled on the AP, the bridged 4addr setup performs very poorly.

The client (x86_64) runs Ubuntu Xenial with kernel 4.4.0. Both the client and the server are ath9k devices. The client is a PC with an adapter that identifies as 'Qualcomm Atheros AR5418 Wireless Network Adapter (PCI-Express) (rev 01)'. I have set up a bridge on a client and connected it to the AP using the 4addr mode on a 2.4 GHz network configured with WPA2-PSK.

I am running Designated Driver r49089 on TP-Link WDR4900 (target mpc85xx).
