wifi hotspot stoped working

[fbs]

Hi there!
I've found a problem with last system update for my smartphone: Android hotspot doesn't allow to access Internet.

The version of the update is 23.0.1.A.3.9

I've seen that the wifi connection between PC and phone works fine (in fact, if a server is mounted on phone, the PC finds it and can connect to the server) and the connection from the phone to another hotspot works, but if the node is the phone, the tunnelling between mobile data connection and wifi network, doesn't work (as no route is made!), so, PC connects to phone, but can't access to the Net.

This happens with Bluetooth too! No wireless hotspot is possible, but they was on prior versions.

This terminal hasn't rooted, so I can't modify routes nor iptables, etc...

Dodgeuk, the configuration depends your provider. The question is than some providers uses DUN to connect network (as Movistar does) and anothers not.
In your case (Three network) not DUN is required. If you travel to Spain and try that connection, it won't work, or international data will be purchased.

I'm not sure if your problem is the same I writed on the forum. I should need more information about the problem.

Anyway, go to the configuration for your Internet connection, see the properties, and on type of connection, try to add "dun" after all the options (i.e.: default, dun). You MUST separe it with a comma.
