Thanks, Russell. I'd seen that page. It indicates that the MT7601U driver is already in the kernel after kernel 4.2. I see it there, it shows up what I run `lsmod`.
But I still can't get it running.
Under `usb-devices` I have
T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#= 4 Spd=480 MxCh= 0 D: Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=148f ProdID=7601 Rev=00.00 S: Manufacturer=MediaTek S: Product=802.11 n WLAN S: SerialNumber=1.0 C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=160mA I: If#= 0 Alt= 0 #EPs= 8 Cls=ff(vend.) Sub=ff Prot=ff Driver=(none)
So I have the kernel module loaded, and the hardware recognized, but the system isn't matching the device to this driver.
Any suggestions?
Got the firmware in the right location? /lib/firmware/MT7601u.bin This guy got it working, albeit without WEP https://github.com/Yackou/nixie-radio/wiki/mt7601u-compilation
Do I go back to the old pre-4.2 driver? Would it react differently to the current one?
Might have to go back. Although I did read that this particular firmware is missing from linux-firmware and that simply putting the blob in the right place fixed it for some Ubuntu distros. The post I saw had your device listed as working out of the box on Ubuntu 15 and some instructions for patching earlier releases. Apparently this is a popular problem. https://github.com/raspberrypi/linux/issues/1090 Usb hotplugging of a NIC, its kind of a funny concept. Trusted networks don't necessarily like that kind of quick change artistry. IMO usb has a shifty history of tracking and managing a hid Endpoint (device) to endpoints (buffers) Pi boards with different revisions, plus throw in systemd targets to boot and your looking at a clusterfork about to happen. The general tone is its not worth the time because better dongles are out there. You could see what wpa_supplicant shows systemctl status wpa_supplicant.service -l Or post the output of uname -a and ps xawf -eo pid,user,cgroups,args for the bigger picture. I'd bet on the firmware blob tho. Thats an issue with a lot of history in Linux and it does look like there is a working one out there. Hope this helps.
I can get another dongle with another chipset, but that will take time.

Hi all.
Making networking run on Linux desktops has always been IMO one of
reasons why it's not caught on. Stuff just shouldn't be this hard.
I have a RPi Model B running current Raspian, and a wifi dongle
claims
to run on it.
These instructions might help. Some driver updates from 2015 and

`lsusb` reports it as Bus 001 Device 004: ID 148f:7601 Ralink Technology, Corp. MT7601U
Adapter
and `usb-devices` says: T: Bus=01 Lev=02 Prnt=02 Port=01 Cnt=02 Dev#= 4 Spd=480 MxCh= 0 D: Ver= 2.01 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=148f ProdID=7601 Rev=00.00 S: Manufacturer=MediaTek S: Product=802.11 n WLAN S: SerialNumber=1.0 C: #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=160mA I: If#= 0 Alt= 0 #EPs= 8 Cls=ff(vend.)

Now... even though it says "Driver=(none)" on that last line, `lsmod` reports: Module Size Used by [...] mt7601u 86636 0 mac80211 650707 1 mt7601u cfg80211 525998 2 mac80211,mt7601u [...] snd_hwdep 6479 1 snd_usb_audio videodev 177702 3 uvcvideo,videobuf2_core,videobuf2_v4l2 snd_usbmidi_lib 22479 1 snd_usb_audio snd_rawmidi 23727 1 snd_usbmidi_lib media 28994 2 uvcvideo,videodev rfkill 21373 2 cfg80211 snd_seq_device 5266 1 snd_rawmidi snd_bcm2835 23131 0 snd_pcm 97825 2 snd_usb_audio,snd_bcm2835 snd_timer 22706 1 snd_pcm snd 68784 8 snd_hwdep,snd_usb_audio,snd_timer,snd_rawmidi,snd_usbmidi_

So there is a module called mt7201u being loaded yet it's not seen as the associated driver to this card in usb-devices and it's definitely not showing in ifconfig or iwconfig.
Any suggestions on what I'm missing is greatly appreciated.
