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.
Out of curiosity, are both of the RT5370 used on the same client device? Did you check that they have unique MAC addresses? Thanks, Ben
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
