Hi everyone, I have two RT5370 devices connected to the same access point. Both devices are very slow, but the instant I disconnect one device, the other speeds up by a factor of 10. The really strange part is that one device will perform slowly even if the other device is basically idle! I've confirmed this with a packet sniffer. I've been trying to do some debugging, and I've found that when both devices are connected to the access point, they report a large number of duplicate frames. I added some debug output in ieee80211_rx_h_check_dup() to confirm that this only happens while both devices are connected. The packet sniffer also shows a large number of retries while this is occurring. Using backports 5.3-rc4 for this, but also tested on 4.14-rc2. I did post about this previously on this mailing list (RT5370 performance issues), but I thought I'd post again with this new information and more descriptive title. I'm a little bit stuck on this for a while now, so any ideas are much appreciated. Thanks! Marlon
