[AZ] Tucson AZ only 6 channel bonding

I got a new cable modem today
Model Name: SB6141
Vendor Name: Motorola
Firmware Name: SB_KOMODO-1.0.6.3-SCM03-NOSH
Boot Version: PSPU-Boot(25CLK) 1.0.12.
Hardware Version: 7.0
Firmware Build Time: Aug 18 2011 10:27:53

I only see 6 channel bonding.
I have the highest service available here (Ultimate), it is suppose to be 150 down.
My old modem (SB6120) was getting 85-95 mbps down 30 mbps up 4 channel bonding downstream, 3 up
My new one getting 80-90 mbps down 30 mbps up 6 channel bonding downstream, 3 up
Am I suppose to get some kind of firmware upgrade from cox or what is the problem?
My gains are just about perfect as well.

thanks

You will get a firmware update from 1.0.6.3 to 1.0.6.8 at some point, probably during overnight maintenance. If you want us to make sure it gets pushed, you can email us at CoxHelp@Cox.com with your service address and a link to this thread.

yeah speeds slowly getting worse now.
I am down to 50 down 30 up, never had anything less than 90ish here before, I hope this firmware update will do it.
Even though I read some other posts in here that 1.0.6.8 doesnt fix it.

Good, it got updated to the correct version. Signals look good, your downstreams are within a 2db range of each other. Getting 5-6 instead of 8 is not unusual, nor is getting 2-3 up instead of 4.

Your download speed really shouldn't be suffering at this point. It should be the same or better. Did anything change other than the modem?

As Kip said, getting six is probably normal as they "need" room to add onto in the future and I often see only 3 channels in a frequency range. 4 channels is more than capable of 120Mbps+ but I wouldn't count on anything much higher and the additional channels help distribute the load more so you should maintain the higher speeds when others are also on line.

Since you never got more than 100, I would seriously look at your network, (routers, switches, nics, cables) to make sure there isn't anything at your end limiting it to 100Mbps all your first numbers seems to point to that but that figure is also what ultimate was until recently (I've always hated 100Mbps for wan link as you end up having to diagnose on both sides a little more since that is a very common limiting speed). I have one house that was pre-wired with cat 6 and one line isn't capable of gig (one of the unused pairs for 100 is faulty, perhaps in the panel, and some of my switches when connected to it go up and down between gig and 100) I've also seen many routers claiming gigabit that the wan port is often "substandard" compared to the built in gigabit switch.

As far as going down to 50 later, it may be that your old modem also would have gone down to that based on usage in the area and at the site you tested.

It is also possible they haven't pushed the correct configuration of your plan to up it past 100 and I'm not sure all areas in AZ can get more than 100. (KipAtCox seems to be "national" in the list of authorized people so you may wish for a more local AZ rep to chime in but I'm not sure it matters) I'm trying to remember if you can see provisioned rates on the SB6141... have you reset your modem after the firmware update? I seem to recall some years ago after a firmware update was pushed, a "default" config file was often pushed onto it and it often took another night or two to get the correct file or one could power cycle it and it might pick it up sooner.

6 down in Tucson is better than 8.

You are on 6 carriers that are dedicated only to Docsis3 modems.

if you had 8 the extra 2 would still be shared by all of the old Doc2 modems and those carriers get pretty congested.

I have 6 only also and it works great.

Have you tried without the router? The new modem is Gigabit and the router may not like that. I have seen that happen.

If that doesn't make a difference the only other thing is could be a bad modem!

this is from cox's website speedtest.
its getting better i guess, I haven't powered off the modem since the firmware update I got last night, I have things running atm I cant DC the modem, I will later tonight and see is that changes anything.

I was using a time capsule that was 5 years old, it was gb conneciton but just old.
I went and bought the Netgear R6300 today and its day and night.
