I started having the "No connection" issue a two months ago. WebOS 3.0.4
But I cannot fix it even with 3 buttons restart! So my TP is dead in the water - no Accounts, mail, apps.
At least the browser and some offline are working...
Actually after this problem when restarting I have the glowing HP logo screen on 2 of 3 restarts.
I have to restart several times just to start the WebOS.
I'm using the TP in Europe,Bulgaria, so first I thought this my be an issue with location.
Tried to change the settings to US, UK .. - no effect.
Then I tried to use several different WiFi networks - still no effect.
The other thing i notice is that you don't have browser cache, cookies, history. You cannot delete them.
I was thinking about HP doctor, but I'm afraid that the problem my persist even after re-install.
Then i'll lose even the several apps that i have.
