Hi
Sorry I don't have a computer, so I can't access via ethernet.
It didn't make any difference to change settings to auto reboot modem reboot and disassociate on low acknowledgment
When I tried the Telia SIM and wifi had disconnected I rebooted and then changed settings to flash memory storage before I changed SIM to mine, if I remember correctly. It probably wasn't enough time to create problems.
After I changed storage settings and SIM to mine I started to streaming video on the tablet, to provoke the problem.
The thing is if I start up the tablet and connect to wifi and do things like checking email and open websites usually doesn't create problems.
It's when I start to do "heavy" things, like downloading files or streaming videos the problems begin.
For example today, when I started up the tablet. I checked my email, did some online banking and opened some websites for probably 30 minutes. But when I opened google play and started updating apps, it disconnected after 30 seconds.
But after rebooting I was able to update the apps.
The strange thing is that it seems to work much better with my TV when I'm streaming. Even if there's problems from time to time, it doesn't occur as frequently.
