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.

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.

Hi all.

Making networking run on Linux desktops has always been IMO one of the reasons why it's not caught on. Stuff just shouldn't be this hard.

This is a red herring. The reason why Linux desktops have not caught on has nothing to do with the technical merits, or lack thereof. It's entirely a business decision. Microsoft and various hardware manufacturers, like Dell, have developed a vast ecosystem of VARs and other support resources. There are great financial incentives for I.T. support firms to promote the Windows ecosystem. There is no counterpart to Microsoft in the Linux world so there are no financial incentives for anyone to push Linux on the desktop. Microsoft and Dell cultivate relationships with VARs and funnel business their way. Who does that in the Linux world? No one. Which large and influential organization promotes Linux on desktops? No one.

If ease of installation has something to do with desktop adoption, Windows would have been displaced long ago. Microsoft has a tremendous advantage in the market because of the OEM relationships it has with hardware vendors. Most people have no idea how difficult or easy Windows is to install because they never have to do it. It comes pre-loaded on their computer. In corporate environments, there are many tools designed to make the mass deployment and management of Windows desktops relatively pain-free so the complexity of Windows installation and configuration is, again, hidden from people.

+1. I am a Windows XP "orphan" on a Dell 3000 PC bought in 2004. Working (slowly) to move to a new desktop PC running debian Linux as primary OS with Windows 7 (likely under QEMU) if needed for a Windows-specific app. My motivation in declining to take the easy route (moving to MS Windows 7 / 10) is a combination of bloody-mindedness and love of all things open source. In addition to the powerful arguments provided by Clifford I., explaining Microsoft dominaiton, here are three: 1. Another "iron grip" enjoyed by Microsoft is the MS Office product suite (and related web-centric stuff) that keeps much of the world shackled to the MS monolith. There really ISN'T any way to obtain MS Office functionality elsewere. For a business that does business with other businesses, lack of MS Office compatibility can be a big problem. I have had to ask more than one sender to provide a PDF, after they had blithely sent some MS-Office attachment or other to me. Scheduling meetings with other organizations that use MS Outlook, can be another pain for the Outlook-deprived Thank goodness for the PDF standard !! My plan in moving to debian Linux is to look for a good document editor that uses the PDF format as its native representation. And of course there is Open Office that (on Win XP at least) is ok, but hardly as slick as equivalent MS product. 2. Another stumbling block for a Windows user looking to "divorce" MS, is the need to choose a desktop GUI. Way too much ink has been spilt and far too many pixels lit, in unproductive linux desktop flame wars. Windows does away with all this productivity-killing confusion over choice of desktop. Here, in helping me clarify my choice of desktop software, is where GTALUG (again) provided enormous value. Some recent discussion around desktops "Re: [GTALUG] Desktop swap" has led me to add Fvwm (that uses X) as a first trial "minimalist" desktop, but still to order the debian Linux DVDs with LXDE. 3. If someone isn't using a cloud-based email IMAP hosting service, but instead using a POP3 / SMTP hosting service and keeping emails on local disk (as I am), dropping Microsoft Windows means converting the local MS-based email database to a new email client. Yes, Mozilla Thunderbird can import emails from MS Outlook and MS Outlook Express (but only when Thunderbird runs under Windows). But frankly, I have too much invested in my precious 1.5 GB of email history to trust the standard Thunderbird import function. So I have written my own C++ program to generate solid conversion integrity checking for the email database conversion. Call me paranoid. And this C++ program isn;t fiished yet. * * * * * * The existence of the GTALUG has become a great comfort to me, on this long road from Win XP to debian Linux. For example, because of GTALUG advice, I'm going to use bash instead of MKSH, I doubled the RAM on the new PC, and made other tweaks to the HW configuration, based on advice from GTALUG members. Presently I'm working with a distributor to get a quote on the parts for a do-it-your-self ATX mid-tower build. I hope to be soon booting up debian Linux on that new box. I'm sooooo looking forward to escaping from the MS stranglehold ... --------------------------------------------------------------------------------

The anti-trust action against MS in the 1990's should have split the company along natural product lines. US Anti-trust folks really lack vision and clout.

I wish Microsoit release "MS-Office for Linux" and put an end to all this sillyness. Who knows, I may see "MS-Linux" along side "MS-Windows". -- William Park <opengeometry@yahoo.ca>

One last thing. I'm using a 2A USB power supply for the Pi B; I hope that's enough. Some previous forum advice suggests that some dongles need a separate powered USB hub which I don't have.
