Default airdroid tethering not working

hi dear Z1 users, in the past i mennaged to connect my phone to my computer using wifi tethering with air droid, i want to achive that in order to avoid opening my usb flap, unfortunatly my wifi signal is too low for effective transfer using the router so i want to directly connect the phone to the computer.

now for some reason in the past weeks i can't get it to work... niether using airdroid own access point or if i create my own and then activate airdroid on tethering...

if anyone else encountered this i'd like to know, or if you know of a better more reliable program that does the same thats also cool.
