But as you mentioned that most time you have problem with WiFi connection elsewhere, maybe there is router overloaded or have different settings. Did you looked on this case this way. Maybe there is two devices with same IP or Mac address.

Of course if your device improved already you should wait for next update as hopefully there will be another improvement for your device.
Maybe you have battery saving mode activated and is blocking your WiFi. Please look on batter saving mode, background task clear. You can deactivate all this future setting and test then

After OTA V3.01_20170112 earlier today I am only getting 3G, before the OTA my 4G was working perfectly.
How can I get my 4G working as normal again without losing everything by wiping the mobile to previous version



Update: I have managed to fix the problem by going into engineering mode > Network selecting and choosing LTE only.



Changing it to LTE only didn't allow me to make calls so I switched it to 4G/3G which worked however it drops back to 3G, I will put it down to my current location atm and I'm hoping it will be back to normal

In which sim slot you have your sim card placed?
This is very weird as you should have in preferred network type 2G, 3G, 4G options. Only when one sim card is in 4G network other can't be higher than 3G so then you don't have option for 4G.
