Dear all, I registered to this forum because I home someone of you can help me to understand where is the problem. This is the situation:

1) in December I activate a new ADSL2+ line (up to 20MB) and then bought a new router Archer D50
2) From February I'm starting to have some issues. Connection goes away randomly and in the router page (192.168.1.1) appear the message: "Disconnected. Please configure your DNS manually)". BUT: I configured primary and secondary DNS as settled by my ISP (Wind - Infostrada, Italy).

Obviously I contacted many times the customer care of th ISP and they have done every time some check. Results: line is good, no problem on the line, no problems with filters. Cabinet is not far from the apartment (less then 1km). Good SNR(15.6) and Line attenuation (22) parameters in download.

So because the ISP tell me it is a fault of my router I attached you the log hoping someone of you can really understand if it is true or if the issue is somewhere else.

Last thing I modified few minutes ago is clear the DNS information (the router uses the one it wants). This action has been done during the period of the log:
