Wifi and bluetooth connectivity problems

[ALargeCat]

So this issue has been going on for a bit with the wifi but both problems are similar.

For Wifi it'll report that it has perfect signal but won't be capable of sending or recieving data. This will persist untill I reboot the phone.

Then after taking the recent update (build 40.0.A.162 with November 6 security patch) the bluetooth has been refusing to connect unless I reboot the phone. This occurs with my Mazda, and my Sena 10c headset.

Exact same. Wifi useless and blutooth not connecting to my car or speaker at home for last couple of weeks unless I restart phone every time.

There's a 6 page thread on this already. My phone doing same. Trying to get Vodafone to swap. They can't find anything wrong... Grrrr

I am also having these issues.  Bluetooth won't connect, and wifi will basically disconnect, even though it is showing that it is connected.  No amount of attempting to reconnect will work until I restart the phone.  It will work for a little while and then it starts all over again.

You do not have to restart your phone ... just turn on and off the airplane mode

After TWO replacement from my service provider, the 3 different devices of XA1 still have the same problems!!... I don't know what to say... Look like every XA1 devices in the world has the same problem... Is someone knows if it's an hardware of software issue ??
