Feedback received on this FAQ entry:
  • As Of 1/1/2013 Cox RI is 25/5 at $50/Month. Incredible service - just incredible!

    2013-06-20 15:07:15

  • Omaha's ultimate is $99.99 not $89.99

    2011-12-02 16:33:08 (ajwees41 See Profile)

  • Cox is offering speeds up to 55mbps down / 5mbps up in certain areas for $89.99 a month. Utilizing DOCSIS 3.0, it is guaranteed bandwidth according to Cox. I also can confirm that the bandwidth is guaranteed with this plan, and it frequently goes higher than 55mbps on most downloads.

  • Extremely out of date. Cox is offering 25mbps/2mbps w/ powerboost to 30mbps.

    2010-08-06 01:42:33

  • The answere to this question is a cop out. We know they offer multiple tiers. A better answer would be; Essential pkg (upload up to 3 Mb/s) expected to be between ____ UP, ____DL and ____ UP, ____DL. Prefered pkg (upload up to 15 Mb/s with powerboost) expected to be between ____ UP, ____DL and ____ UP, ____DL. Premeir pkg (upload up to 28 Mb/s with powerboost) expected to be between ____ UP, ____DL and ____ UP, ____DL.

Cox High Speed Internet IP addresses are dynamically assigned to each computer on the Cox High Speed Internet network. Therefore, an IP address can change at any time. If you need static IP addressing, please contact Cox Business Services for a business solution that fits your needs.

Feedback received on this FAQ entry:
  • you want dynamic ip address because this will prevent more viruses/computer attacks in the future

  • I'm not sure about COX in other areas, but in the Hampton Roads area, COX HSI uses a DHCP scheme where DHCP is used to provide a static address which is provisioned based on the MAC address; It is very, very rare for your IP to change, and tends to happen only under rare unknown circumstances or replacement of hardware, such as the cable modem or router. In almost 10 years, my IP has changed only twice. Pretty good for DHCP. It would seem that COX uses a static allocation scheme but provides it via DHCP for ease of configuration on the user end (as DHCP provides the user with a very simple plug-and-go setup of their computer or router).

No. This formerly free benefit has been removed.

"Cox Communications No Longer Offers Personal WebSpace Effective December 6, 2011

Cox has discontinued offering Personal WebSpace to our customers. Declining usage of the Personal WebSpace service has highlighted the need to focus our resources on other priorities, such as increasing our Internet speeds and providing new services such as Cox Secure Online Backup."

Information on signal levels: http://homepage.ntlworld.com/robin.d.h.walker/cmtips/signal.html#signal

For non-DOCSIS 3.0 modems:

Downstream power level (Receive): -15dbmV to +15dbmV
A value of -15 or worse indicates a poor downstream signal path. A tech would aim for a value close to the optimal 0 dBmV, but a good cable modem should be capable of working within the broader range of -15 to +15 dBmV, provided the downstream Signal to Noise Ratio remains good enough.

Upstream (Transmit): 35-52 dBmV. A value within the range +35 to +52 dBmV is within spec with the low to mid 40's the most common. If the cable modem is going offline, and the upstream signal strength is at or above +52dBmV, then a poor upstream path is probably the problem.

Carrier/Noise Ratio: 35 db and above The downstream Signal to Noise Ratio must be 35 dB or higher. The lower ratio the more noise and the poorer the performance. The Cable Modem will have to keep requesting retransmissions of packets with uncorrectable errors.

DOCSIS 3.0 modems:

Downstream power level (Receive): -15dbmV to +15dbmV
A value of -10 or worse indicates a poor downstream signal path. A tech would aim for a value close to the optimal 0 dBmV, but a good cable modem should be capable of working within the broader range of -10 to +10 dBmV, provided the downstream Signal to Noise Ratio remains good enough. Additionally all downstream channels should be within a +/-2db window with respect to each other.

Upstream (Transmit): 40-52 dBmV. A value within the range +40 to +52 dBmV is within spec with the low to mid 40's the most common. If the cable modem is going offline, and the upstream signal strength is at or above +52dBmV, then a poor upstream path is probably the problem.

Carrier/Noise Ratio: 35 db and above The downstream Signal to Noise Ratio must be 35 dB or higher on each channel. The lower ratio the more noise and the poorer the performance. The Cable Modem will have to keep requesting retransmissions of packets with uncorrectable errors.

Feedback received on this FAQ entry:
  • If you are using tests to look for those low downstream levels and high upstream levels, you are compensating for something that isn't standard which can cause future problems when things on the CMTS and around the infrastructure change (more CM's being applied to a CMTS). It is always essential to give best effort towards 0 on the downstream (stabilized in between the low and high threshold of -15 to 15+) and about 42.50 on the upstream (stabilized between the threshold of 33-52 with a 9.50 midpoint {33 + 9.50 = 42.50 and 42.50 + 9.50 = 52]). Never use a conventional CATV amplifier for your modem line. Only a powered return "splitter" should be used to provide a seperate return channel for both CATV and DOCSIS signal to balance out levels. Only apply attenuators or amplifiers on the CATV lines because the power range is more lenient and the way tuners work are different than a modem's handling and tight requirement for a clean data signal.

  • My job is testing and refurbishing cable modems with docsis 3.0 for a major cable company. Our tests look for a downstream between -15 dbmv to -9 dbmv and an upstream of 50 dbmv to 60 dbmv. Anything outside these ranges can cause connection problem and packet loss.

    2013-03-21 08:20:43

  • I would suggest that the requirement for allowable channel signal level unbalance for D3 connections be added to this FAQ answer.

You should ping your first hop apprx fifty times. (To get your first hop do a tracert to anywhere and note the first address like 10.xx.xx.xx
Then go to the DOS prompt and enter: ping -n 50 xx.xx.xx.xx)

The pings to your first hop should normally be under 30ms with an occasional ping in the 60-70ms range. Disregard the first ping. If you see high pings or a high spike and are running Win9x/ME hold down Ctrl/Alt/Del and "End Task" on all programs except for Explorer and Systray. Then try the ping to your first hop again. If they look normal now that usually indicates it is a program running in the background that is causing the problem. Reboot and try disabling programs loading at start up to find the one causing the problem.

If the pings remain high or high spikes after closing all programs except Explorer and Systray, then you can eliminate the possibility of a background program as a cause.

At Cox, we strictly enforce our authorized posting policy. Employees must go through a validation and authorizing process before we sanction their postings on the Cox Forum here at Broadband Reports. We also keep an eye on postings, and with the help of the members of this forum, make sure we respond professionally and responsibility to questions. In doing this, we can ensure your confidence in our employees that opt to help out here.

That said, participation by employees is voluntary. We don't tell anyone they have to do this. Thus, you'll find some markets have great coverage while others may not be directly represented. Likewise, we have a lot of folks that opt not to post. Instead, they frequently "lurk" in order to stay in touch with the feedback we receive here.

The Ultimate package uses frequency spectrum higher than the existing Video and HSI spectrum. A install allows a tech to insure your cabling, splitters, and other equipment are ready for these frequencies.

Thanks to CoxJimR See Profile for this FAQ.

Feedback received on this FAQ entry:
  • We ran "ultimate" as part of the tests last year for several months. No equipment or cable upgrade was needed, if the cable was "good enough" to deliver decent low noise digital TV to the HD cable boxes. If the cable box diagnostics showed a higher than usual quality degradation, then, the cable drop, tap, etc was suspect.

Currently any tier of service with the exception of Ultimate can be self-installed in most cases with the exception of customers subscribing to satellite TV service. This is to prevent the possibility of the satellite TV lines becoming interconnected with our cable lines to minimize noise issues. Ultimate Tier requires a professional installation at this time due to the new range of frequencies being used to provide the service. This is to make sure that these newer frequencies work at your residence and ensure a positive customer experience.
