Slow share performance on my RN 104 since upgrading to 6.4.0

Thanks, JohnNulty, I agree - it seems like too much of a coincidence not to be related.

joel80:  I'm pleased that that worked for you, but it's really not an option for me.  It would take 4-5 days to copy the data off, then do the reset and another 2-3 days to copy the data back on, and that would be after I spent £150 on external drives, and accepted no data protection for a week, hoping not to lose anything.

For me, that's not a solution but as I say I'm glad it was for you.

Netgear really need to be the ones to resolve this, or at least provide an alternate path back to 6.2.5 that can be done in-place, if they don't intend on fixing the problem.
