D-Link DIR-890L wireless failures

For Developers
1

Hi all, really want to use this tri-band device as a backhaul but just can't get the WIFI to work. Basically after a few minutes of very moderate transfer the entire wireless interface will fall apart, with tons of error logs like attached. Tried both release and snapshots. I know bcm is not stable but the similar Netgear R8000 works miles better than this, only needs a daily wireless reset to stay robust. Kindly suggest.

Check supported channels per 5GHz radio using iw list and choose either one of those or automatically. As it stands with Broadcom wifi - enjoy that it works at all.

5

All channels are in the working list (out of "radar detection" too). Looking for more because (1) this is not working, won't sustain over 5min of moderate transfer (2) the same radios work much better with Netgear R8000 so must be something missing here?

6

Likely power supply, disable one of 5ghz radios and check again.

7

Disabled radio2 and now radio0 runs at extreme low speed like 1Mbps... looks like something is seriously wrong here...

8

Disable them, power routeroff on , and start radios one by one.

9

No improvement. So sad... tried the FLOSS driver DD-WRT, even worse...
