I just tested with verbatim 4.14 and even though the wireless works, iwconfig reports something strange: iwconfig wifi1 wifi1 no wireless extensions. However, my device works as expected (albeit still slow): wifi1 Link encap:Ethernet HWaddr 18:d6:c7:0d:47:3c inet addr:10.20.1.175 Bcast:10.20.1.255 Mask:255.255.255.0 inet6 addr: fe80::281d:5f27:eb1b:8ded/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:38903 errors:0 dropped:0 overruns:0 frame:0 TX packets:24689 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:51524413 (51.5 MB) TX bytes:5503039 (5.5 MB) dmesg output: [вт ное 14 12:30:38 2017] usb 1-1.1: This Realtek USB WiFi dongle (0x2357:0x0108) is untested!
