As long as there was no congestion that the additional channel mitigated it's fine. Far better the upgrade is handled properly as areas are ready than apparently all over the place with a modem firmware upgrade that's not really a part of the preparations.

it is alright it is back now. My connection got increasingly slower yesterday evening (like it was winding itself down :)) and around 10 ish just came to a complete halt. I whipped the power cord out of the shub and popped it back in and now I am back on 3 channels and my qam64 is back

So far I have noticed that whether people have 2 or 3 upstreams, and whether they have 16QAM or 64QAM the mini-slot size is 4.

I have the VMB business service and see a Mini-slot size of 128. I wonder the significance?

There's none; different firmware is giving the same result but in different units.

......

FWIW historically 128 MS size has been related to SH1(VMDG480) hardware/firmware combo's. One related to number of ticks(6.25 micros), and the other bytes....

Care to explain-like-i'm-an-idiot as to what the mini-slot size actually is and what the numbers mean?

Yes. If I remember rightly the SH 1 is a Broadcom SoC while the later revisions are Intel. Probably explains the discrepancy.

Correct

Sooo....what's the mini slot size, then?
