Following on from our attempts last night, I have had a bit of a play, not exhaustive.
the site that compares adapters is: https://en.m.wikipedia.org/wiki/Comparison_of_open-source_wireless_drivers I have here Clives ADDON AWU650 using the rtl8188eu (I think) My Aqprox appusb150nav21506685 using MediaTek MT7601U an old Zyxel adapter using zd1211 chipset in the Raspberry Pi Model B rev2 the Aqprox works and has always worked. The other two don't but I know in the past the Zyxel one has. Plugged each into my desktop - Kubuntu 18.04 - the Zyxel worked straight off, I am now connected by it. AWU650 Not recognised, Aqprox not recognised. Here is the output of dmesg from the time that I unplugged the zyxel adapter: [30471.057232] zd1211rw 3-1:1.0: error ioread32(CR_REG1): -19 [30471.059949] zd1211rw 3-1:1.0: error ioread32(CR_REG1): -19 [30471.060078] zd1211rw 3-1:1.0: error ioread32(CR_REG1): -19 [30475.780861] usb 3-1: new high-speed USB device number 6 using xhci_hcd [30475.929264] usb 3-1: New USB device found, idVendor=0bda, idProduct=a811 [30475.929270] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [30475.929274] usb 3-1: Product: 802.11ac WLAN Adapter [30475.929278] usb 3-1: Manufacturer: Realtek [30475.929282] usb 3-1: SerialNumber: 00e04c000001 [30728.151997] usb 3-1: USB disconnect, device number 6 [30733.193285] usb 3-1: new high-speed USB device number 7 using xhci_hcd [30733.706774] usb 3-1: New USB device found, idVendor=148f, idProduct=7601 [30733.706781] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [30733.837599] usb 3-1: reset high-speed USB device number 7 using xhci_hcd [30733.986326] mt7601u 3-1:1.0: ASIC revision: 76010001 MAC revision: 76010500 [30733.986949] mt7601u 3-1:1.0: Firmware Version: 0.1.00 Build: 7640 Build time: 201302052146____ [30734.419518] mt7601u 3-1:1.0: EEPROM ver:08 fae:00 [30734.889296] mt7601u 3-1:1.0: Warning: mt7601u_mcu_wait_resp retrying [30735.209320] mt7601u 3-1:1.0: Warning: mt7601u_mcu_wait_resp retrying [30735.529315] mt7601u 3-1:1.0: Warning: mt7601u_mcu_wait_resp retrying [30735.849323] mt7601u 3-1:1.0: Warning: mt7601u_mcu_wait_resp retrying [30736.169330] mt7601u 3-1:1.0: Warning: mt7601u_mcu_wait_resp retrying [30736.169335] mt7601u 3-1:1.0: Error: mt7601u_mcu_wait_resp timed out [30739.385334] mt7601u 3-1:1.0: Vendor request req:07 off:0080 failed:-110 [30742.585438] mt7601u 3-1:1.0: Vendor request req:02 off:0080 failed:-110 [30745.785493] mt7601u 3-1:1.0: Vendor request req:02 off:0080 failed:-110 [30745.785551] mt7601u: probe of 3-1:1.0 failed with error -110 [30745.785923] usb 3-1: USB disconnect, device number 7 [30746.057502] usb 3-1: new high-speed USB device number 8 using xhci_hcd [30746.550507] usb 3-1: New USB device found, idVendor=148f, idProduct=7601 [30746.550513] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [30746.677814] usb 3-1: reset high-speed USB device number 8 using xhci_hcd [30746.826559] mt7601u 3-1:1.0: ASIC revision: 76010001 MAC revision: 76010500 [30746.849699] mt7601u 3-1:1.0: EEPROM ver:08 fae:00 [30747.051166] ieee80211 phy3: Selected rate control algorithm 'minstrel_ht' [30747.088535] mt7601u 3-1:1.0 wlx000c4300cc2d: renamed from wlan0 [30747.099882] IPv6: ADDRCONF(NETDEV_UP): wlx000c4300cc2d: link is not ready [30747.116186] IPv6: ADDRCONF(NETDEV_UP): wlx000c4300cc2d: link is not ready [30747.162384] IPv6: ADDRCONF(NETDEV_UP): wlx000c4300cc2d: link is not ready I have reverted to wired connection to send this email.
