I tried the answer found here: https://askubuntu.com/questions/912498/tl-wn722n-is-not-recognized

but it doesn't work:

any help appreciated

lwfinger commented 7 years ago

What part do you need help with. Your posted log shows that you do not need to use this module.

vallettea commented 7 years ago

thanks for your answer. All the posts I've red about this dongle say that your driver can enable it. I thought that installing it would solve my problem but it doesn't. Any insight on this particular dongle (and its chipset) ? best

AndyMender commented 7 years ago

The chipset in this dongle is definitely Realtek RTL8188EU as I use it with Fedora on my workstation. @vallettea could you also post back the output of ifconfig and/or ip link and the relevant information from dmesg about the driver (dmesg | grep 8188eu) to see whether the appropriate interface gets created at all and what exactly happens at the driver level?

I'm not using a raspberry pi, but hopefully this will work for you and others:

https://github.com/michaelgugino/rtl8188EUS

I took the source from tp-link's site. These are some mods to get the code to compile. Next on my list to try is modifying the driver: http://elixir.free-electrons.com/linux/v4.4/source/drivers/net/wireless/realtek/rtl8xxxu

That's in tree experimental source and should cover this chipset, but I haven't tried it yet. It's also possible 8187 drivers might work.

vallettea commented 7 years ago

I tried your solution @michaelgugino on raspberry, here is what i did and here is my problem: Perhaps you have an idea (i'm not a linux expert at all)

apt-get update
apt-get install raspberrypi-kernel-headers
apt-get install binutils build-essential
git clone -b rpi-4.9.y --single-branch git://github.com/raspberrypi/linux.git
cd linux
cp /usr/src/linux-headers-4.9.35-v7+/Module.symvers .
cp /boot/config.txt .config
KSRC=$PWD
cd ..
git clone https://github.com/michaelgugino/rtl8188EUS.git
cd rtl8188EUS/
make

michaelgugino commented 7 years ago

Sorry about that, I missed didn't add 'export' the the line 'export KSRC=$PWD'. That will add KSRC to your environment variables. Just tells the vendor's make script where to find the linux source.

vallettea commented 7 years ago

thanks for your help again. I still had a problem:

make ARCH=armv7l CROSS_COMPILE= -C /root/linux M=/root/rtl8188EUS  modules
make[1]: Entering directory '/root/linux'
Makefile:628: arch/armv7l/Makefile: No such file or directory
make[1]: *** No rule to make target 'arch/armv7l/Makefile'.  Stop.

but never mind I'll just buy another dongle. best
