[CA] SB6141/SB6180 or Cisco?

Still looking for a modem to upgrade to. Currently on SB6120, I'm anticipating the speedboosts rolling out to COX, but I don't think that will happen anytime soon. Currently on the premier tier bonding 4/1.

They also increased the price on Premier recently, and Ultimate is the same at $99. Should I keep the SB6120 if I upgrade to ultimate? I figure if I can get my speeds with 4 channels down, it could be better than 8 channels due to interleaving and overhead?

»ww2.cox.com/residential/palosver···_premier shows Premier as 25/2 (31/3 with powerboost), Ultimate 50/5 (55/5.5) At the moment, if you are hitting your max speed with 4 channels down, there is no a reason to upgrade the modem.

If Irvine, CA mirror's AZ's speed upgrade; Premier should be 50/10 (63/13 powerboost) and Ultimate 150/20 (188/25). If this were to occur and you are on Premier with an old 100mbit router, the router may become the bottleneck. 4 channels down can support 63megabits down, but may not during primetime. Obviously you will need a 8x4 modem and gigabit router for Ultimate.

Price-wise, you can pickup a 8x4 Cisco DPC3010 used modem on ebay for the low $30's and sell the SB6120 for a cheap upgrade. I am not sure of the benefits of spending the extra money for a 8x4 SB6141/SB6180 vs the DPC3010.

Hi Matty,

Thanks for your input. So at this point there is no reason for me to upgrade unless I decide to go with Ultimate ( 50/5 ) and unable to hit speeds during prime or at night. I generally don't buy used gear, and already have a gigabit router. Cisco E4200 for that matter.

Alright guys, just got the upgrade today. Still using the SB6120 that's currently provisioned.

Speeds are hitting 65/6 with boost, and about 50/4 sustained which I would say is good enough.

Now for those that say latency does not improve or change with the upgrade, I would say this is false. I'm getting on average worst case 2MS BETTER than before, with improvements up to 8MS better!

Now I'm on 4x3 bonding. Latencies seem to have taken a hit. Instead of being at 4-6MS first hop after the upgrade to ultimate, I'm now back at premier latencies although a bit more consistent. 7-9MS.

Probably due to the changeovers of equipment. You have to expect that a large market won't get a single "flip of the switch" and everyone is on the new setup. Generally changes are rolled out over weeks to months and certain area's come online sooner than others. This means one set of equipment is seeing less usage and will see a little bit better latency until everyone is switched over then it will be back to normal as more people are added on.

But that does not explain why the moment I got upgraded to Ultimate, my latency was much better than before?

Seems to be QOS / some sort of traffic shaping policy.

Ended up getting a SB6141 to test with still at 4x3 right now with the same crap latency. 9-13MS first top ( direct to modem )

Update: Had coxtech push out a new firmware. Now at 8x3.
