buraktamturk has discovered a solution to tethering on L:

Lightbulb Tethering Fix
Here is solution for tethering (both usb and wireless).

Tether just as usual. Then disable tethering and re-enable it. (this step is important otherwise dhcp server is not started)
After doing that both your phone and computer will not connect internet, because of invalid routing table. (internal bug from l preview)

just connect to the phone shell with 'adb shell', or terminal software on android (connectbot or android terminal emulator will fine)

shell@hammerhead:/ $ su
root@hammerhead:/ # ip route | grep rmnet0 | grep link dev rmnet0 proto kernel scope link src
Note the gateway here (, and set this default gateway. (and yes, my provider gives me nat'ed private ip addresses)

root@hammerhead:/ # route add default gw dev rmnet0
Enjoy the tethering!

Note your phone must be rooted otherwise you will not able to pass beyond 'su' command.
I packaged up the following in a sh script that gets run with Tasker when enabling tethering (I use it for my Nexus 7 in my car):

Select Code
ip=$(ip route | grep mnet0 | grep link | sed 's/.*src //')
route add default gw ${ip} dev rmnet0
I saved the above in /sdcard/

I then run a command in Tasker:

Select Code
/system/bin/sh /sdcard/
I "think" this is working. Since I ran it manually, the IP is now stored in the routing table. If the IP switches and tethering suddenly stops working, ill know it's not functioning anymore and will tweak the script.
