100M : Now got 6 Downstream Channels

[RB2004]

Hi, this morning my superhub locked up, and had to be rebooted.. after rebooting it I noticed it now has 6 channels.

Connection speeds seem more consistant now as well funnily enough.. dont know why they didnt just go straight to 8 which they keep proposing instead of 6?

But also, this increase in downstream channels seems to of caused my power levels to increase by about 3dBmV.

any stats from the SH to copy and post?

Looking at VM forum seems are more downstream channels available

the upgrades start coming hopefully soon

Vm need to get upstream bonding in place.. As when I get 120mbit upgrade there will only be 12mbit upload... By is offering 20mbit upload!

upstream power is the lowest I have ever seen. It is within spec but keep an eye on it dude.

I've seen a 16db upstream, also it's quite common in my area to have 30 to 35

[RB2004]

My upstream was 47 but for weeks it went to 36 I posted about it but was told its fine.

There is only 1 tap in the pit so it can't be adjusted that way by means of a higher attenuation point. So it's on their network somewhere causing it.

im on more downstream channels now also and just started a 2.2 gig download so will see if it varies during the download at all.

Mine in the winter went as low as 30.5 dBmV and sometimes lower, gives a good indication of how warm it is outside... lol. Though it used to be around 40-50 dBmV until they added another downstream channel from four to five, which I find odd as many people are getting 6 or 8. This was a few months ago (I made a thread on it.) I'm on a Motorola BSR so always had four.

Speaking of low upstream, I remember my connection being very unstable at the time when they added the new channel because the upstream was too low (28-29), it just couldn't get a lock on to the network till it increased. Mick Fisher also had this problem.
