Is there a problem with a gateway

[#1]

Tried logging on no internet, checked router failed to connect to gateway 195.166.128.123  disconnected and reconnected to another gateway and no problem

[#2]

Had the same problem a couple of hours ago. Disconnected the PPPoA session and reconnected. No problem since then.

Yes that's what I did, took a couple of tries as got the same gateway first time
