I’m really annoyed now, I have to restart the router x times, because the modem is always offline, than works again for a while (maybe 1 hour)… than again offline can someone give me a tip, maybe support…

The firmware ist the newest one!
Are you using auto setup or manually you have created a profile ? What is your ISP?
Can you download and test the beta firmware ?

So it’s O2 cellular in your case, when I remember right.
Hi

Right, it is O2!
Internet Service Provider ISP = O2
Although the beta looks the same as the stable one, I installed it yesterday and the modem has been keeping the connection since then, let’s see how long…
