A Large Decrease in SNR Margin in the Night

My Netgear DG834GT (which had always been rock solid at SNRs going down to about 3dB), is now disconnecting due to noise at not much less than 5dB. This has al started within the last two weeks. Nothing has changed in my setup, I have tried it in the test socket but it still disconnected, I have attached a screenshot of my SNR before and after it disconnects.
By the way, in RouterStats, does anybody know how to zoom out the graph so I can capture the whole graph?

Just adjust the timeline which will increase the time covered - click on configure then graphs
To alter the vertical scale press the Alt key and hold down the left mouse button when you can expand or contract the vertical scale

Lines starting to degrade cause of weather maybe? thats a shot in the dark tbh.
Maybe something to do with solar activity?

HI sjrinfroyle,
Have a look at our troubleshooting guide for some tips. If you don't see any improvement then I would raise a fault.
