FS#2079 - MT7621 - lost RX stream

Device: TP-LINK RE350 v1
OpenWRT: 18.06-SNAPSHOOT 22.01.2019
Wireless setup:

  config wifi-device 'radio0'
      option type 'mac80211'
      option channel '1'
      option hwmode '11g'
      option path 'pci0000:00/0000:00:00.0/0000:01:00.0'

      option network 'lan'
      option disabled '0'
      option wds '1'
      option wmm '1'

Problem and solution:
AP and STA works on Channel 1. STA few seconds after connection to upstream AP losts RX stream.

What does "lost RX stream" mean? Do you have throughput/connectivity issues, or is it just the reported rate?

sumsu commented on 04.02.2019 14:35

Yes, I've connectivity issues. In 1 minute or less after the connection with ap is established it alwayse look the same, rx bitrate goes to 1.0 MBit and I'm unable even to send ping to ap.
I've did some research and I've found out that problem is with 2.4GHz wifi module. Second module (5G) is working OK.
Right now I've installed snapshoot 30.01.2019 and it is working only on 11g band. After 4 days and 21h it is working stable. But it has only 54Mbps. Every time when I enable N band I lost connection. This mean connection to AP is established, but I'm unable to send anything.
My current configuration:
config wifi-device 'radio0'

      option type 'mac80211'
      option channel '10'
      option hwmode '11g'
      option path 'pci0000:00/0000:00:00.0/0000:01:00.0'
      option greenfield '0'
      option diversity '1'
      option powersave '0'
      option txpower '30'
      option country 'US'
      option log_level '8'
      option disabled '0'
      option legacy_rates '0'
      option noscan '1'

config wifi-iface

      option device 'radio0'
      option mode 'ap'
      option ssid 'XXXXX'
      option encryption 'psk2'
      option key 'xxxxxx'
      option disassoc_low_ack '0'
      option network 'lan'
      option disabled '0'
      option wds '1'
      option wmm '1'
