Hi Sam,

After the update my AC dongle stopped to detect AC net’s, he only detects N.

[ 1865.964334] usb 1-1.5: new high-speed USB device number 5 using dwc_otg
[ 1866.095282] usb 1-1.5: New USB device found, idVendor=7392, idProduct=a812
[ 1866.095307] usb 1-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[ 1866.095318] usb 1-1.5: Product: Edimax AC600 USB
[ 1866.095328] usb 1-1.5: Manufacturer: Realtek

Thanks,

AC600 isn’t a MediaTek dongle. It says Realtek in your paste above

That’s a Realtek device. Start a separate thread as this thread is about Mediatek devices.

Ok

I tried this earlier and did not work

wget “https://www.dropbox.com/s/pvepk50no24t17x/rbp2-kernel-mk2.deb?dl=1” -O kernel.deb
sudo dpkg -i kernel.deb
sudo reboot
After reading your messege i searched and found this one

Can you try: wget “https://www.dropbox.com/s/pvepk50no24t17x/rbp2-kernel-mk2.deb?dl=1” -O kernel.deb sudo dpkg -i kernel.deb sudo reboot And post dmesg if still not working Thanks

And i am very happy to say that it is once again working flawlessly.
Thanks alot really appretiate it.

I tried this, and my adapter shows up again, but only for N, not AC.

I also did both the updates.

Here is the dmesg link:

Means nothing to me, but I do spot some errors.

Hello,

I have encountered a similar issue. I have Edimax wifi dongle AC450 (EW-7711ULC) and it is not working after latest updates. Output of dmesg contains following:

[ 3.387950] usb 1-1.4: new high-speed USB device number 5 using dwc_otg
[ 3.401363] fuse init (API version 7.26)
[ 3.533081] usb 1-1.4: New USB device found, idVendor=7392, idProduct=a711

[ 3.533098] usb 1-1.4: Manufacturer: MediaTek
[ 3.533102] usb 1-1.4: SerialNumber: 1.0

Whole dmesg output: https://paste.osmc.tv/emudipuzel

Output of lsusb:

Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The ifconfig command shows only the internal wlan0 interface (I also tried to disable internal wifi with no luck).

Could you please help me? Thank you.

Probably missing VID/PID. Not related to the issue above as those users have a detected dongle and connectivity.
