trogers 0 Report post · CID: 567754833326 Posted January 26, 2006 Then it is this router connection that is imposing a throughput limit of 0.44 Mbps. You need adjust your connection back to standard and retest your network. The ccs file has adjusted your throughput to more than 4 Mbps. Quote Share this post Link to post Share on other sites

Razoroth 0 Report post · CID: 65250917522 Posted October 9, 2007 I know this is an old thread, but if you've come across this page while searching for a solution to your slow internet connection speed from charter, read below. I'm not 100% sure this is your problem, but this may help explain a little about what is happening to you. I'm currently having this problem myself, and charter's internet service will go down because of this. You may experience download speeds from IE or Firefox of around 1-7kb/s because of this. Like I said this is only what I've come across so far, and the symptoms seem to be in charter's services and not your or my router/modem. I am currently hooked directly up to my modem. I've reset it multiple times and got the same results. Check this link out, it may help. Sun Outages Quote Share this post Link to post Share on other sites
