I have utlimate service which is supposed to deliver 300 mbps. However, i was consistently getting readings of 60 - 70 mbps. I called tech support to troubleshoot and they are sending a tech out. However, i then checked the speed using the Microsoft Edge browser and low and behold the speed tested out at 330 mbps consistently. Went back to the Chrome browser and the reading was still below 100 mbps. I then used my chrome browser with Speedtest on the Ookla site and the reading was 300 plus mbps when not using the Cox server. If i use the Cox server closest to me, then the reading is back below 100 mbps when using Chrome browser. My conclusion is that this is some type of software issue with the Chrome browser and the cox servers. Go figure. It is something that Cox should be aware of. Slow speed test on Cox Server but fast on LA servers. I used the Cox Speed test on their website and the result indicated my ultimate internet speed was about 70 mbps. Way slow as it was supposed to be at 300 mbps. I measured this repeatedly and got similar results at different times of day. Then i used the Ookla Speedtest website and used the LA servers and got speeds around 300 mbps which is where the speed is supposed to be at. What gives here? Was on the tech line with Cox before i realized that my speeds were much higher on the LA servers. Cox recommends you do the speedtest on their website which uses their servers. So why would the speeds be so much lower using their servers?
