Somehow when we placed our order online the Fast Connect Kit did not get shipped to us. We then called Cox a few days after our kit was to arrive and they said the kit would be here in a few days, but again the kit never arrived. So to make a long story short the kit finally arrives almost two weeks late.

I have only been using COX HSI since July 06, and so far I'm very satisfied with the service, the connection has been rock solid and with the upgrades we have been getting lately it's all that much better.

We had just migrated over from DSL, and with the distance from the CO., our fragile copper lines that could barley hold a 1.5/384 sync, I could not be any happier with Cox cable.

As for the service, we are on the preferred package 9/768 and are getting slightly above our advertised speeds.

***************************** UPDATE July 16 2008 ************************************

We have had our service for 2 years now and couldn't be happier with the overall service. The speeds have been rock solid and the connection has been very reliable.

*****************************UPDATE Feb. 25 2010***************************

The connection is still rock solid and were getting slightly above our advertised speeds on the preferred tier which was just upgraded from 10/768 to 12/1.5

***************************UPDATE Feb. 20 2013**************************************

Our connection still has been rock solid and our speed on preferred has been increased to 18/2 and we are getting slightly above the speed on the speed tests.

*************************Update October 30 2013***********************************

Our connection has been rock solid with one exception of packet loss in our neighborhood since my last update. The Cox people were on the problem and it was solved in a few days. We also just receive a upgrade in speed from 18/2 to 25/5.

Three complaints about Cox's Ultimate HSI:
1. Advertised speed 150Mbps down, Cox website tests at 180 Mbps, Speedtest.net 80 Mbps.
2. Data Usage Meter is inaccurate-reports 18 Gbps per day usage even on the two weeks I was out of town on vacation.
3. The Preferred and Premier HSI tiers received a free speed increase but Cox has done nothing for the Ultimate tier customers.

Aug. 8, 2014: Price on bill was as expected. I did not get connected until about 10 days after subscribing, so I called, and Cox gave me a credit for the days I wasn't connected -- that was a big plus. About a week into the new service, all seems to be working well (desktops, laptops, tablets, phones, reliability, connectivity, bandwidth, etc.), except that Xbox live keeps getting disconnected. I kept both my old Internet service (including modem-router that came with it) for about a week, so I could compare both services. Xbox live works perfectly fine with my previous service, but it is intermittently disconnected with the new Cox modem-router. The modem-router is a Ubee DDW366. Cox's tier 1 and 2 tech support have not been able to help me with this problem, so I am going to switch out the modem-router with a different brand at the Cox store, and see how that goes. (This is odd since I'd expect that a significant number of Cox's HSI customers use Xbox live, perhaps Ubee is a new brand for Cox?)

Need to adjust your QOS

Most Cox users use either Motorola or Cisco for their modems / routers..

I got a Cisco DPC3010 modem with a Cisco RV042G router.

You should be able to adjust your modem's / router QOS setting to prevent disconnects from your XBox.

Re: Need to adjust your QOS

Thanks a bunch - great info.
P.S. I did wind up adding port forwarding in the Ubee's settings for the Xbox's (fixed) IP address (UDP and TCP for ports 88, 3074, 53, 80), but that did not resolve the problem.

Re: Need to adjust your QOS

Might want to take a look at this.. Looks like your not the only one with Xbox issues and Ubee modems / routers.

»forums.xbox.com/xbox_forums/xbox···661.aspx

»forums.xbox.com/xbox_forums/xbox···301.aspx

Also you might want to put the Xbox in the DMZ zone.. Let it have a direct connection to the internet.

I'm signed up for the Cox Preferred internet package, 50mbps down and 10mbps up at a cost of $64.00 a month. Cox just doubled our speeds here in Nebraska as of July 2014, and that is why I've updated my review today. Cox did not raise the monthly cost for this increased speed! The speed is just right for my needs and I've had excellent 24/7 service. The internet has improved to the point where I'm able to view most TV programs online. I'm considering dropping my Cox TV service and maybe upgrading my internet speed to the next higher tier. It has been several years since I dropped our Cox phone service. I'm using a smartphone for all phone calls and have not had any problems. I even had one occasion where I had to call 911E and the emergency response was excellent. I'm assuming they used my phones GPS to locate us.

COX HSI

I don't know when you wrote your review dude but I have COX Ultimate here in San Diego and as of Oct. 2013 the speeds are 100 down/20 up (with the actual numbers much higher usually 130's/ high 30's). This is for $99 a month. Some other Cox locations now have 150 MBPS down which is fairly compatible with EURODOCSIS and what South Korea can deliver.

Re: COX HSI

Appreciate your reply. Yes, it has been a while since I've updated my review of Cox. I will update it soon. Their speeds have improved quite a bit from years ago. My son lives out in Irvine CA and he has speeds almost like yours. Guess living out here in corn country it takes awhile for the upgrades, ha. Best wishes and enjoy all that sunny California weather. I'm from Redondo Beach CA and hope to return soon.....I'm tired of all this snow and cold weather every Winter.

A recent "speed increase" was just put in place. At this time last year, the download speeds were 80-90Mbps (uncapped) Then the Premier speed was capped at about 32-36 Mbps. The recent "increase" raised the 36Mbps to about 46Mbps.

Due to the increasing number of annoying commercials, I'm about ready to drop TV service and go back to broadcast tv.

We currently use Premier package. We get about $237 for bundle with TV, Internet, and phone. My current home network are Cisco DPC3010 8x4 modem, Asus RT-N66R router, Cisco 24 ports POE switch, and three Cisco Aironet N600. Our devices are to many on list that handle with Netflix, Facetime, Online Gaming, Skype, Web, Youtube, etc. with no problem. I don't really see any problem with spike from modem or router at all. We do get 65 Mbps download and 12 Mbps upload at mostly of time. It is excellent service we got. Good news Cox are making double speed for now in USA for only Preferred and Premier start with 50/5 and 100/10.

The router and modem currently using:

Modem: Cisco DPC3010
Router: Asus RT-N66R

Speed is usually goes around 65Mbps/12 Mbps but it depending on powerboost max out. No probem have appear. Just very recently issue from Cox which are upgrading and maintainance. I am happy with that.

They have data caps but they are not enforced. We are getting a free double internet upgrade in August. Love Cox wish it was a bit cheaper but beyond that no complaints. My only real complaint is wish employees were a bit more knowledgeable about what cox is doing.

·AT&T Southeast
Running Ultimate, I see speedboost downloads up to 195Mb/s for the first couple of minutes then down to 160Mb/s. It is that speed downstream any time of day I test it. That's Mbits, not MBytes.

Uploads are 30Mb/s at first and stabilize around 18-20Mb/s.

I'm content with it, but could always be faster. Currently it's the best deal the New Orleans area far as I know.

Order and install was good overall. The tech who was sent to the house was very competent and polite.

Running a Motorola Surfboard 6141 I bought myself after a 2-week-long string of random disconnects. Didn't help the disconnects. Those went away on their own. Guessing it was Cox messing with their network.

24x7 phone support is nice. They can't do a whole lot for you during non-business hours since billing and a few other offices are closed, but they can do basic troubleshooting, reset your modem, book a tech, etc. I have always gotten a tech out within 48 hours of calling, usually same day if I call before lunch.

The contractor field techs don't seem to do much besides replace connectors and splitters. As far as signal analysis and comprehending the modem's built-in diagnostic page, forget it. The Cox-employed field techs know their stuff though.

Do be aware Cox has caps now. So far, they don't enforce them much if at all.

I am an ex-Verizon employee in a FiOS area but can not get it due to my landlord, and have a wife who was not happy with the upload speeds that 7M DSL could provide, so our broadband appetite had changed over the years.

No problems with it, other than using a low pass filter to block the MoCA signal for my router from getting back into Cox's network causing loss of the internet early in the morning. Once I took it off, all was well and have had no problems since.

UPDATE 7/25/14: I have since the initial review added telephone service from Cox as I left Verizon in 2012, and recently added their Contour DVR service. They upgraded my telephony modem to a Cisco DOCSIS 3.0 unit for free, and other than some kinks not resolved at the time of the Contour installation (none of the crimp-on connectors in my coax network were replaced), everything has been fine and steady. Unfortunately, still the only game in town as a result of my landlord.

I link my New Jersey office which has FIOS with my Nevada office which has COX HSI. Fios is running 25 up and down. Cox is running 50 down and around 8 up. The cost of around $120 is about the same. Yes this is very expensive but when your livelihood (accounting business) depends upon it then you bite the bullet and pay for it. I cannot see much of a difference between the two although I prefer FIOS as the throughput seems faster on the Verizon network. I wish we has fiber to the curb but that is generally only available at the Las Vegas casinos. There has been virtually no downtime on Cox. Installation was fast and professional. In the long run it has helped the business since I am able to access large tax files without any problems. Videocam between the two offices is not perfect but acceptable.

I am updating my review of Cox. For several reasons I upgraded to their Ultimate service. It is expensive but they are the only game in town offering 150 speed. Tech support is excellent. Installer was top notch. Reliability which is super important is there. Sure I have had to reboot the modem a few times but that is no big deal. I am waiting to see how fast Century Link will bring 1 gig speed over to Henderson,Nevada. Competition is good for everyone

Update on Cox

I use Cox Ultimate service and it has been a pleasure dealing with the. Speeds hit 180 which is terrific. I link my Nevada office and New Jersey office. Unfortunately in NJ I have to deal with Comcast which is horrible and have to contend with lower speeds and more importantly unreliability by Comcast. Yes it is expensive but when you are working with large data files you need that speed. Computer equipment is state of the art but in a commercial environment you do not cut corners. Cox tech support is excellent and I rarely have issues with them.

Would be interesting to see the trace route path between the two offices.. See where you data goes.
