Today i managed to connect the station wds at 80MHz channel. Signal is -56 and i have very low datarates. I have attached a photo.
 When station was ddwrt and AP openwrt the datarates were 866/433. TX won't do more than VHT-NSS 1 although RX it's not good either because it's a 4 chain radio and it should do VHT-NSS4.
Thank you,Klevis

wants to sponsor it.  Please understand I, and probably everyone else working
on OpenWRT, am busy with lots of other projects and community work often
gets pushed to the back burner.
