I've run out of ideas and am hoping someone here can help. All I want to do is connect a client to my 5Ghz network. My client: OS is Debian stable "Stretch" with sysvinit instead of systemd Atheros AR9462 (World roaming 0x64 regdomain in EEPROM) "iw reg set US" "iw list" shows both 2.4Ghz and 5Ghz bands available. "iw wlp3s0 survey dump" shows received traffic on 5Ghz bands. There are oodles of 5Ghz AP's within range, but scans (including passive scans) reveal only 2.4Ghz networks. My only guess was that it won't transmit due to regulatory requirements, but I cannot make it work. What I've tried: Running with and without CRDA Running latest mainline kernel Hacking around on the ath9k driver and nl80211 to remove all regulatory enforcement. Nothing works and I'm pulling my hair out. Any help would be greatly appreciated.
