My provider informed me about suspicous/expensive telefone calls.

Is my speedlink 5501 hacked?
Can I check this anyway?

@ slope game: You should look for a list of connected devices in the router's interface. Check for any unfamiliar devices that might indicate unauthorized access.

I the recents day there was no unfamilar device in the list of connected devices.

for the older ones I'm not able to say ok or not ok to every entry.

I made now a factory reset and changed all passwords again.

Now I've lost a couble of menu entrys in the config menu of the 5501. Especally the entry for the firmware update.
How can I make sure that the latest frimware is installed?

You bought Speedlink 5501 from a store… or was sent to you from the provider?
