Slow Internet
A number of threads have been started about slow internet. (http://forums.cox.com/forum_home/internet_forum/f/5/t/18484.aspx, http://forums.cox.com/forum_home/internet_forum/f/5/p/18566/69263.aspx#69263, http://forums.cox.com/forum_home/internet_forum/f/5/p/18540/69240.aspx#69240, ...) The slow-down for me seemed to happen overnight, 08/01/17. Watching the process of accessing web pages, or my non-cox legacy POP3 email server I noticed that the majority of "time lost" was in resolving the domain name. This was not just associated with the initial web page or mail server request. It also applied to loading elements within web pages (image, video or external content) that were referenced by a domain name. Delays in loading individual content elements within a page were as long as those to open the initial web page. Totaled up, I could often select a web page, go to the coffee pot and fill my cup and return to my computer, a 40' journey round trip, and the page would just be in the early stages of populating its non-text content all the while status bars proclaimed "waiting for <insert domain name target here>" for 20 - 30 seconds before each element loaded. Either: Cox DNS servers suddenly became under powered / overwhelmed by name resolution requests, OR Cox was intercepting all DNS requests, and performing extra processing on the DNS references before passing the request on to the named server. What made #2 a contender was the insertion of Cox advertising on couple pages requested from servers located thousands of miles away that are not served by Cox. Also, it is likely, due to money in politics, that Ajit Pai (FCC Chairman) will rescind Net Neutrality rules in late September. It could be that Cox has rolled out a "live beta" of their "Detect and Throttle" ISP software that would necessarily have to intercept DNS requests before routing them to a particular "speed queue". This was somewhat supported by a little experiment I repeated at least a dozen times: With two tabs open in either of three browsers, select to load any web page you like that is not hosted by Cox. Switch to the second tab, and select to load Cox.com. When Cox page loads, log into your account. When that page finishes loading, go back to the first tab, and it will not yet have finished loading all its content. Whether the issue is #1, #2, or another possibility remains to be seen. But it would be hard to imagine how this happened literally overnight at the first of the month without the roll-out of significant software or hardware updates to Cox DNS infrastructure. So, in case this massive slow-down was not intentional I hope this posting is seen by a Cox ISP engineer, or passed along to them. Trying to deal with support simply gets you "reset the modem... power cycle your router... it must be your browser / anti-virus / personal firewall / computer's internet / network settings..." when the problem is outside my (and all user's) walls. Cox ISP Engineering - please take this seriously., investigate and resolve. It is frustrating seeing response like dial-up days or bad DSL days. Speed tests from Cox or independent servers appear proper for upload / download time, but latency is way to high even on Cox's speed test. There is a problem and it is not within users' walls.

Speed Issues with Motorola Surfboard 6141
I just purchased the Motorola SB6141 from Amazon to replace my previous Motorola SB6120. After activating it online, I've noticed the SB6141 has speeds significantly slower than the SB6120. Looking at past Speedtest.net results from my iPhone: Motorola SB6120 Download: 64.84Mbps Upload: 8.00Mbps Ping: 68ms Motorola SB6141 Download: 10.09Mbps Upload: 2.21Mbps Ping: 24ms Based upon the glowing reviews for the SB6141 and having the Premier package on Cox, I thought I would see faster speeds. Not significantly slower speeds. I've tried resetting both the modem and my (recently purchased) Apple AirPort Time Capsule 802.11ac router. Both didn't work. I looked over some previous threads like this one, but I currently have the latest firmware as per that thread's suggestion. I have a Cat6 ethernet cable arriving tomorrow, but I don't think that'll be the solution for the problem at hand. Any help to get this issue solved would be greatly appreciated. Here's the information from my SB6141:
