Internet drops regularly and router showing high rate of T3 timeout events

Hello

 

I am using a Arris SBG6400 at home. Very frequently I experience internet connection drop outs (...this page cannot be found...). Looking at the event logs of the router I can see a high rate of T3 events.

 

What can I do about this?

 

Thank you

Martin

 

The events from the router look like this:

Please also post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.
