Hi magichugs,

You would actually be able to use any modem that is on our approved modems list, we do however recommend that you get a Docsis 3.0 cable modem.  Equipment issues can be the problem with speed issues but there are other things that can cause that as well.  We would need to check everything to be sure what the actual cause is. 

You mentioned a router that is directly connected to your laptop, to test the speed I would recommend connecting the modem directly to the laptop instead.  The router could be part of the problem with the connection speed.  We can take a look at the signal levels of the modem as well, if you could email us at coxhelp@cox.com and provide the MAC address of the modem, along with the name & address on the account I'll be more than happy to take a look.

I send the email to coxhelp@cox.com  with the info and I took cox off my network,  because I also have AT&T DSL.   My laptop is connected direct to the cox modem, nothing else is on cox internet .   I was getting speeds from 32mb  to 17mb   this at 10 am today this is the best time to get the best speeds in my area, but after 6 pm. is when I usually  start getting low speeds , I was getting speed test from your site , I was using my laptop connected directly to the cox modem and did this most of last weekend.   

Derrick, 

        it is 8:30 now is when cox need to check my speed.  I got a tech coming out Wednesday but as usual  it will not be the time to check the speed.  At around 6 it starts going down  by 8: 30 my 6 mb DSL out does cox.  last checked I'm getting 4.93 download off cox and 6.56 off AT&T and this is off my network for at&t.  I'm doing the testing from speedtest.net. I ran over my test limits on cox at 10 am in the morning.  The odd thing is my upload seem to stay 4.04 and 4.22.   Which at times like now my upload is higher then my down loads. I'm going to keep cox off my network, till it is fix because cox is even pulling my DSL down.  So check it out now it is connected to my laptop only.

Hi Tiffany,

        My internet is better then it was but it is still a problem. The Tech was better then anyone before him because he got into my modem and adjusted the spikes which helped a lot. He said I need another modem and told me which one he thinks work the best. I got one on order and today or Monday I hope to get it.  Till I get and install that new modem, my problem or better but not good enough. We will see, I just wish cox would give sent some kind of a  notification, I would have had the modem one less problem to guess at.   

                                   Thanks for your concerns,

We've been having modem problems. Cox brought another modem out a few months ago still having problems,, we paid a private pc company to come over. He said its the modem!! It runs hot, so did the last one!! Fix my Internet service. Tonight my emails are not coming through. The Internet is super slow and just now checking the modem it's very hot!!

Did I mention that the Cox service tech who came to my house said our modem was running hot because other people are connecting to our service! We had to pay for a pc guy to come out spend 4 hours to tell us NO one is using our service but us.......and the modem was red hot!! 

Hi Cindy1954,

                I got another modem coming, I can only try things they  recommend.  My internet was doing a lot better but this weekend was as bad as last weekend.  If the new modem doesn't do the job it will be great  but if it doesn't , the ball goes back to cox.   I learn years ago, internet is to important to rely on one service provider.   I have  cox and AT&T.  At&t has proven to be more reliable then cox, the last two years but I can't get the speed from DSL that I can get from Cox.  Cox can run good for a year or two then you get problems that can take from two weeks  to  two  months to fix.  Once they get it right your are good  till they start updating to the   next level.  I think they charge to much and cut to many corners on there service.  Cox needs to provide there own equipment and upgrade it as needed.   Charter cable does just that.    AT&T  U-Verse is coming my ways soon with the right speeds, and I will try it.

Hi Tiffany,

     My internet is better but far from being good.  I can get on line better then before but the up and down speeds are ridiculous. I'm sure the work they are doing will correct this but cox is not worth the money.  People are not getting what they are paying for they will move on when the option comes available.  Till then I'll pay the price but I am not happy with the service.
