I generally use my router to tether my phone internet.
As soon as i connect my phone to the usb port and enable usb tethering on the phone the router gets the internet from my phone.
I upgraded my router from 4.3.7 to 4.3.11 today.
The tethering is not working properly now.
Everytime I dis-connect and re-connect my phone the portal says connecting under tethering and shows an option “Abort”.
If i click abort and click “Connect” it work fine, but the problem shows up again after disconnecting the usb and reconnecting it again.
I tried resetting the entire modem. it still has the same issue.
Now, I reverted back to the previous firmware and don’t see this problem anymore.
Hope this reaches the devs and will fix this in the next update.
