100M New Modem - Page 4

All areas should be going to 8 channels sooner or later, and probably 2 upstreams, the superhub will lock onto all 8 down and 3 up, whereas the VMNG300 will only lock onto 4 of the available downstreams, and both of the 2 upstreams, and will handle 120mb just fine, just less efficient load balancing across the channels

meaning inconsistent speeds

craigj2k12 · 02-04-2012, 19:33

I doubt you would notice a difference, infact 4 channels on the VMNG will probably outperform the superhub for browsing and everyday use. You will only notice the speed drop in more congested areas where there is a severe amount of downstream congestion (which there shouldnt be anyway) and if there was, the superhub would double its effects by buffering all those packets, so its a win win situation keeping the VMNG really

thenry · 02-04-2012, 19:35

I thought the VMNG turned into a glitchball once more channels got pushed

craigj2k12 · 02-04-2012, 19:42

nope, it gets offered 5+ channels and locks onto 4 of them

Getting a bit annoying now with disconects, techs coming around and sorting it, then this happening again!

Downstream power levels are a little low, try taking off a 'Forward Path Attenuator' if you have one.

Thanks for reply, haven't got one.

On phone to VM now just on hold apprently theres a fault in the area something is too low it's at 25 should be around 30. The power I think he said.

Got a Tech coming between 12 and 4 today.

craigj2k12 · 03-04-2012, 13:22

the downstreams fine, its the upstream power thats wayyyy too high

New levels after tech has been.

thenry · 03-04-2012, 15:28

up is still a little high, did he jiggle at the cabinet

craigj2k12 · 03-04-2012, 15:31

its within spec, as long as it doesnt sneak up beyond 55 it will be fine, keep an eye on it

borrissey · 03-04-2012, 17:18

my TiVO boxes are 48 and 51.

Had a tech out today as well and it's gone back up again.

craigj2k12 · 03-04-2012, 17:21

yeah thats way over, youll need another tech visit, make sure he changes your tap at the cabinet!

thenry · 03-04-2012, 17:27

why they jumping so high though
