Airport Time Capsule Intermittent Internet

Hi All,

I am having intermittent connection issues with my Time Capsule on Wi-Fi.

I only physically see the issue when I go into Airport Utility and the Light next the the internet connection flicks green for 1 second then orange for 2 seconds. I notice the connection loss when streaming files over the internet and also in Mail I think it trips up my Gmail with an error due to the connection.

Is there any fix or solution for this? I have tried recreating the network using short names as well as renaming the TC to a short name which was one suggestion.

I have tried what I think are most combinations however am unsure if the modem or the TC is the issue. I have been hesitant to play with the modem specs too much as it's provided/set by the ISP but happy to have a look here too.

Any suggestions welcome.

Thanks.
