Slow internet, DNS issue, not pref. speed
Upgraded last month to preferred internet, brand new Cisci DPC3825 mode/wi-fi. It worked fine for about 3 weeks. However, for the past week, I've been seeing constant DNS issues (resolving host message), and slow speeds, yet when I run speed test using the Cox support page, the speed is fine (for non-preferred, coming in at 25-29 Mb/s). Same goes for speedtest.net. So, 2 issues - 1, the DNS issue, I removed the usual DNS servers, and went with 68.105.28.13 and 29.13, as suggested in another forum post. This does not appear to have resolved the issue, still "resolving host", even for common web sites. Second issue, slow response. This could be related to having problems resolving the address, but until I resolved the DNS issue, I won't be sure. When I went to my cox account, it said my internet device was DCI382P. Not sure if that lines up with my modem, which is a Cisco DPC3825. Any suggestions? TIA.13KViews0likes9Comments
OMAHA: DNS issues - DNS in router?
First, you "upgraded" my account by sending a new Internet modem, a model UbeeDUBW656 -- yet, on this page, < http://www.cox.com/residential/support/internet/article.cox?articleId=b2ec95d0-7ef9-11df-5590-000000000000>, you do NOT have this modem listed as preferred. That may well be the problem. Ever since I installed this modem, there has been intermittent yet consistent "DNS" problems on all of my devices that are connected to this modem/router. Both wired and wireless suffer from these DNS issues. I have tried to bypass the modem's DNS features to no avail. I am a very savvy internet-capable IT guy. I know how to troubleshoot. The DNS port/ip filtering is somehow wacked out on this modem/router. And, I cannot even change the DNS settings IN the router. This bites. The symptoms are the DNS addresses will not resolve. Running nslookup and choosing different servers, always time out, when this problem exists. For the last 24 hours, I have had this problem, and resetting the modem is not working. I have cleared, flushed, registered, re-configured multiple computer devices just to be sure it was not a local problem. The problem resides in either the modem/router, or at COX in Omaha. I am VERY unsatisfied with the quality of COX Internet, and feel that I am overpaying for such service. -- Unhappy in Omaha.11KViews0likes19Comments
Barefruit Ltd and the tracking of internet traffic
I am logging thousands of hit a day from a company called Barefruit Ltd. From what research I have done it has partnered with Cox to track and redirect traffic to sponsored links when you mistype an address in the address window. How can I get this to stop, and why is Barefruit slamming my connection with requests to connect to my computer?Solved11KViews0likes1CommentFed up with slow DNS lookups
OK, I posted about this months ago and got a few replies with suggestions (thanks--checked them all out) but I am still suffering. Here's the situation: Home network with Motorola "Internet router". My client is running Win 8.1. I mostly use Chrome and Firefox, but the info below is from Firefox since it reports connection status at the bottom of the screen (Looking up . . ., Waiting for ... etc.) The bad experience: especially for busy pages that make lots of connections, like Yahoo and other commercial Web sites, I have very very slow completed page presentation. Based on Firefox status messages the majority of time is spent waiting for the various contributors to the page (including adwords and other advertising junk.) OK, but a significant amount of time Firefox is displaying "Looking up xxx" Maybe 30-40 percent of the total wait time, though this varies and sometimes is not a factor. The "Looking up xxx" status messages sometimes appear for up to 5-6 seconds at a time (for each lookup.) This is far above the maximum times reported by DNSBench (see below.) In addition, I fairly frequently get an error saying "Can't locate server" and advising me to check my spelling and try again. This is a DNS error, not a failure of the target server to respond. And it's for absolutely mainstream URLs like amazon.com or google.com that are most certainly in DNS and should usually be cached. And these are not URL's I am entering by hand, of course, so they are not spelled incorrectly. Nor is this limited to Firefox: in fact, I have gotten "Can't locate server" from my T-Bird e-mail client trying to locate smtp.cox.net!! Tech support: I have had a couple of sessions with Cox support, who confirm that my IPv4 DNS settings are correct. My Windows Connection Properties for IPv4 are set to accept the Cox-set defaults: 68.105.28.11, 29.11, and 28.12, in that order. Things I've tried: 1. Using Google DNS responders. -- No apparent difference in performance. 2. Based on a suggestion here in the Cox Forum, I tried changing with my IPv6 settings (disabling IPv6 in Windows, accepting defaults, specifying Google IPv6 addresses.) Again, no apparent difference in performance with any of these. 3. Diagnosis with Gibson's DNSBench. This indicates that performance of the Cox default IPv4 responders is fine--as fast or faster than others in the DNSBench standard lineup, and good absolutely in terms of average and max lookup times. Of course these tests are at a point in time but I've run them several times with similar results. I am at the end of my rope on this problem. Frankly, all I can think to do is try FIOS . . . Any ideas out there??? Thanks6KViews0likes9Comments
Low Upload speeds.
basically through exhaustive testing on multiplecomputers routers and switchs i still only receive 6-9mbps upload on testmy.net and real uploads to youtube google cloud and dropbox. My download speeds are fine, Called tier 2 support ans said its likely a issue with my sb6190 since all signal reading good and speedtest to cox and speedtest.net are fine and requested i try a new modem.5.4KViews0likes14Comments
Zoom 5350
Anyone have best settings for the Zoom 5350, including wireless? I already found out about the "IP Flood Detection" option, but trying to maximize my combo modem/wireless router. Also, I tried finding firmware updates for this unit, but Zoom states it needs to come from Cox - any idea if this will happen?5.4KViews0likes2Comments
DNS Hijacking (A.K.A 'Enhanced Error Results')
NOTE: Please do not lock this forum thread unless a valid solution has been proposed. If this thread is locked without a solution or reason as to why the thread is locked, I will consider COX will not fix this issue. Problem All invalid hostnames that are forwarded through my Cox router resolve to the ip address: 92.242.140.2instead of properly returning a NXDOMAINDNS response. Troubleshooting I have changed both the IPv4 and IPv6 DNS server settings so that none of my server lookups should be contacting COX DNS servers. I have opted out of Enhanced Error Results from the internet tools section of my account settings page I have rebooted my router after applying the settings from #1 and opting out from #2 I am testing DNS resolution outside of any browser (using nslookup and ping) The tooling from #4 shows that the ip address resolution is coming from 2001:578:3f::30which is a COX owned DNS server, and is nowhere in my router configuration (I have overridden all IPv4 and IPv6 dns server addresses in #1). Finally, ifI route all of my traffic through a VPN,I do not encounter this issue, which leads me to believe there is something explicitly in the router software/firmware which is the source of this behavior. Conclusion Despite changing my DNS settings and opting out of enhance error results, I am still seeing incorrect DNS results returned by a COX server that my router is not set up to use. This is not a browser issue. I am seeing incorrect behavior outside and and inside of any browser. I have already made the DNS settings changes as suggested by other forum posts, which does not solve this problem: http://forums.cox.com/forum_home/internet_forum/f/5/t/16006.aspx http://forums.cox.com/forum_home/internet_forum/f/5/t/14154.aspx http://forums.cox.com/forum_home/internet_forum/f/5/t/14649.aspx Details System: ARRIS DOCSIS 3.0 / PC 1.5 Touchstone Residential Gateway HW_REV: 3 VENDOR: ARRIS Group, Inc.
