Downstream SNR varying

Hi is it normal for your downstream SNR margin to change every few seconds? Mine appears to be varying between a high of 30 and low of 25, it seems to change every second e.g. 25, 27, 26, 30,26 etc...

My Upstream however is rock solid on 30 and doesn't change.

Any info on this would be greatly appreciated.

Yes it is fairly acceptable behaviour within those ranges. You dont often get this commented on because most modems only seem to update the reported SNR every few minutes or so.
