[SailfishDevel] Question about connecting a Sailfish phone to Ubuntu Linux box

[rikujolla]

Hello,

I always had problems when I used my development laptop in  my home wlan 
and was wired to the phone with usb cable. I could not solve the issue 
most probably caused by my home router. Currently I create a hotspot 
with my phone and connect the Ubuntu laptop to that network. Then I 
develope in that network without any cables and without any problems.

Best regards Riku
