Hi list, I use AR9280 PCIe card in AP mode for about two years in Lenovo x230 laptop (whitelist removed). Works perfectly.
After moving to a modern laptop there is no ability to install PCIe card into it. I tried to use one of USB dongles I have based on: 1. AR9280+AR7010 2. AR9271 After attaching AR9271 USB dongle and restarting it by '/etc/netstart athn0' It broadcasts BSSID, and client can get IP address from it. But no data flow between USB AP and any client device connected. Most frames are dropped or corrupted on the 'air' level even USB AP and client on the same table. ICMP between AP and client goes with huge delays in both ways, most packages drop. Delay is about ~3.5ms but sometimes 337.3ms and more. The same issue with both USB dongles on x230 laptop (original PCIe was removed and nothing changed in configuration of PF and /etc/hostname.athn0). I tried three computers with OpenBSD 6.9amd64 GENERIC installed. The behaviour is the same with USB AR9280+AR7010 and AR9271 dongles. Once I return back PCIe version of AR9280 card all works like a charm. It looks like a bug in athn(4) driver related USB based devices. Martin
