Hi Seph,
New SH arrived on Thursday and I installed it that night.
Tried connecting via wireless and initially had problems connecting. Wired it up, dropped the 802.11 mode from 300Mbps to 145Mbps and this sorted it as everything connected and worked fine.
Then switched to modem mode and it has been in this since as my laptop is wired to it and I only need the wireless occasionally for other devices. This has currently got a System Up Time of just over 1 day and 10 hours which is the longest I've had since end of Nov / early Dec so at present (although I don't want to tempt fate) all seems to be working well.
Another additional and unexpected bonus is the quiet. The old SH always had a sort of high pitched squeal coming from it that others have reported and appears to be something to do with the power cable whereas this one hasn't.
The one thing I'll keep an eye on are the downstream power levels. The old hub was reporting the 5 channels all at 6.X dBmV whereas the new one is currently showing the 5 channels ranging from 8.6 - 9.3 dBmV. Are these levels within tolerance or a little high? May they just settle down given a bit of time? I've still got a 6dB attenuator attached and wondered whether this may need swapping for a 10 dB attenuator although I know this will require another tech visit as I know they won't just send one of these out.
So far so good, let's hope it stays that way.
Cheers
