I reach out for help to you.
Unfortunately, the D-LINK DIR 645 still has issues, which are present in OpenWRT 18.06.0. The WLAN does not operate stable.
I acquired the wireless information until wireless brakedown as recommended for debugging:
I am new to the issue of debugging wireless hardware. I am not sure what I am looking for in this data. Can you help me on this?
Thanks a lot
PS: I had a look at the source code for the router and also to other issues related to the used chipset. Perhaps this can be related to the bug? Strange, I found different assumed chipsets, e.g. RT3662 (in bug report) and RT2860v2_ap 2.4GHz 802.11bgn (OpenWRT wiki).
