I do have other devices connected to the LTE network. Yes, you may think its not reliable. But I have made numerous experiments, including having my laptop also connected. Laptop internet works, Obi does not connect to Google Voice (but does show solid green on the network side... and on the web it shows as connected). Both phone lines are not connected.
It happens in front of me just now... all of a sudden, the two green solid lines of the two phone connections came up. It will work like that and then will again disappear.
Internet should no be thought of always perfect. There are ways to retry sends, retry connections etc. If this is a design default its a problem. If this can be fixed with a firmware patch, I.e. to enable reconnects to the internet in set intervals, then maybe this can solve it.
But, I can tell you I have manually tried to resent the box (disconnected power and waiting for device to reboot), and no help. It wont connect to Google Voice though it does show connection to the internet.
Maybe my Obi202 is faulty. I bought it through Amazon and already sent a request to replace both the ObiWIFI adapter and the Ovi202 device (my 30 day money back/exchange ends on Feb 1st, so I cannot risk and wait any longer... ).
I should get the new device end of the week. I hope this will help.
By the way, this did NOT do it before! It was OK and all worked fine!!!
I.e. same 4G LTE network and all, same Ovi202/WIFI connecting through the Mobile Hotspot. Was leaving it all night, no problem. In the morning all worked fine....
So this started happening just around the security issue with the Voicemail Google took action to make changes for (including that now we need use pin code to access the google voicemail and we can no longer know if new voicemail is available through my cordless phone - shuttered dial tone / etc).
So there were changes that made my device not working as before.....
Thanks!
