My connection syncs at 6500 and usually I set my SNR at 150% reducing the sync to 6200 (but very stable).

Today, when I came home I couldn't browse and although I was still connected noticed that my SNR was down to 4.5.

I rebooted and got a sync of 5000 (SNR=8.5)

I set the SNR to 150% and get a sync of 4200 (SNR=11.5)

This is quite a nasty drop of around 2000 in the sync. Anyone else noticed this?

I experienced something similar (but worse) last August after storms.
