Hello,

I have a problem with my vDSL connection. Every +-40 minutes my router lost connection.

The interesting point is that it doesnt drop DSL connection, everything seems fine status tab. I think there is maybe some problem with losing DNS connection, cause I am able to ping random IP.

Manual connection drop and establishing the new one doesnt help, I can "fix" this with restarting router only.

This appears every +-40 minutes (38-42). I have no problems with connection until 40th minute when connection goes down. No slowdowns, no network spikes, everything is fine. DSL signal is very good according to statistics and DSLAM is 30 meters from my flat.

I have changed default DNS servers to Google DNS servers, but it doesnt help. I have reset to defaults and set DSL again too but it didnt help either, It is the same everytime.

Until 40th minute every single test in diagnostic ends with "PASS", when connection drop the last two items failing.

Test DNS ROOT and Network Connection Status Inspect.

Could you give me some advice guys?

Thank you..
