on the same place a Fritzbox 4040 reach 200Mbit in both direction over the air. After i buy a other Router with MT76x2E WiFi chip an get the same problems. But the mesh networks between this tow router is MT76x2E not fast but it works. Is there an incompatibility in 802.11s between ath10k an MT76xxx WiFi ?
