Internet drops for a 30sec to a minute or so and reconnects.
My internet connection has dropped several times a day for the past couple of weeks. I looked the modem logs and see some errors at the time this happens. I was wondering if any one had any suggestions. Below is one that I had yesterday in the evening. It's a Motorola Surfboard Model Name: SB6120 I mask the Mac Address and can repost with them if needed.

Unable to connect to Cox High Speed Internet Network
I had Cox High Speed Internet installed Thursday, April 12. The installation went quickly and painlessly and in less than an hour I had internet access. I bought a ZOOM 5350 Cable Modem/Wireless Router which worked great right out of the box. Since last evening, Friday, April 13, I have been unable to access the Cox High Speed Internet network. I called tech support and went through the usual diagnostics (PC network configuration, wired/wireless connections, etc.) Tech Support can see the Cable Modem on the network and can remotely reboot the Cable Modem on the network. I can communicate with the Cable Modem (wired and wirelessly) without any difficulty through the PC, but am unable to pass or receive any data through the Cable Modem. The only thing I have been able to determine is that the Cable Modem's Dynamic IP Address is no longer dynamic. After approximately 20+ reboots and resets since the loss of the internet, the Cable Modem's IP Address is the same every time. When I reboot the Cable Modem without a cable connection, the IP Address is blank, so the old address is not being retained in the Cable Modem. Since the Dynamic IP Addresses are being furnished by the Cox network routers, it seems to me that this is a network problem. I restored my (substandard) AT&T DSL connection so I have internet access, but want to get my Cox internet problems straightened out so I can finish firing AT&T. Any ideas?5.7KViews0likes2CommentsMultiple disconnects.
I am really starting to get frustrated. I've had multiple disconnections...I would estimate between 30-40. The disconnect lasts for 30 seconds to a minute. I noticed it first with my ps3, then my iPad/iPhone. To make sure it wasn't my router, I connected my ps3 directly to my modem (one of those Motorola docsis 3 modems). That didn't help. Got a DNS error. I changed all of my DNS to those found on openDNS but to no avail. I'm thinking this may be a cox issue. Anyone else having this issue? P.s. I did all of the usual things like restarting the router, modem, etc.5.6KViews0likes7Comments
Splitter disrupts service
My internet doesn't work when the modem/router (a Motorola SB901) is connected to the wall via a splitter. That is, the main cord out of the wall to a splitter, and a cable going to the tv and one also to the modem/router. It works fine if I bypass the splitter and plug it directly to the wall. The entire system worked fine, until one day it just decided not to. I have tried three different splitters, thinking that that was the issue, but nothing works. Any help?5.2KViews0likes1CommentMcAfee Firewall
Anyone else have this problem - Cox updates to Firewall block internet connections. My computer stopped working a week ago, Cox said it was my Network interface card, Dell said it was a driver problem, purchase of a new card and download of driver updates didn't solve the problem. Office Depot told my wife we needed a new wireless adapter, haha. I finally enlisted a prof from a local college and he figured out it was the McAfee software - switching off the Firewall and Eureka - Internet connection restored4.5KViews0likes1CommentInternet Connection Issues due to recent McAfee update.
Attention Cox High Speed Internet Customers: A recent McAffee-issued software upgrade is causing some Cox customers to lose their internet connectivity. McAfee has since corrected the corrupt file, but you problems may persist. Refer to the following Cox Support Alert to correct the issue.

no access to internet tools
Does anyone know why i cant access internet tools. I just get a page saying "if you had cox internet, you would be here by now" chat support 3 times, 2 calls to phone support and supervisors. I need to add email addresses and I am getting frustrated. I feel they are providing half the service so i should only pay half the bill3.7KViews0likes3Comments
