(I downloaded the three files from here:, then put them in their own directory and ran sudo dkpg -i *.deb. (I have a port that sometimes doesn't work in MTP mode for some reason, I think the connectors are getting loose)ģ - I tried rolling back libnl-3-200, libnl-genl-3-200, and libnl-route-3-200 as per Hadaka's suggestion in this post: I DID connect the phone to the laptop with a USB cable.Ģ - I have tried using different USB ports. Let me start with the things I HAVE tried, to eliminate some of the obvious suggestions.ġ- I enabled 'USB Tethering' under Settings -> Mobile Hotspot and Tethering. USB tethering worked fine before, and I haven't made any major changes (I recently installed apache2, see my addendum at the bottom of this post regarding the 2 things I tried in case that somehow affected the tethering issue). Let me emphasize that USB tethering IS ENABLED ON MY PHONE. So, I had USB tethering stop working out of nowhere for my Samsung Galaxy and my Lenovo Thinkpad.īackground you will probably want: Ubuntu 14.04.5 LTS, Lenovo T430s laptop, Core i5-3320m (64 bit, obviously), Dual-boot with Windows and Ubuntu on different partitions.
