Trendnet TEW-691GR "disconnected due to excessive missing ACKs"

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,

I set up LEDE 17.01.4 on my router Trendnet TEW-691GR one week ago. After some time router starts to disconnect wifi clients with system log entry "IEEE 802.11: disconnected due to excessive missing ACKs". Even after a full reinstall of firmware problem still remains. I noticed that disconnect happens when wifi clients trying to download or upload massive files, or starts speedtest.net check (fails on uploading stage), but not every time. Please, help with this problem :confused:

Could you try the 18.06 RC1?

Do back up your settings first please and then use sysupgrade without keeping settings.

Hello again,

I tried both rc1 and now release 18.06 for over mouth. Now the problem changed. Sometimes randomly, sometimes when trying to download huge files (16gb, drops after 500-700mb, but not every time), wifi connections starts to work incorrectly. Internet over wifi doesn't work, ping to router timeout or host is down, but over lan everything ok. Can I fix it somehow? I'll be glad to any help.
