R7000 Connectivity Issues
My R7000 router had been working fine until the last few days. I began to get intermittent dropouts from the internet. They mostly appear as failures to load thumbnail pictures in emails, eBay, not p...
I swapped out the suspect Cat5E for a shielded Cat 6 cable yesterday afternoon. After 12 hours, the LAN connection to my wife's iMac appears to be stable. She is getting proper email downloads and web page renderings. I don't want to jinx it, but I'd say the problem is solved–for now!
I truly believe the router was at fault initially because both of my hard-wired iMacs were sufffering similar download/rendering problems. After performing a reset to factory defaults and a re-install of firmware, the LAN was more stable. Switching to a different DNS appears to have helped the stability and speed. I also believe the biggest problem was the Cat 5E cable to my wife's iMac.
Lesson learned (again!): Always check the cables first!
I am running Firmware Version 1.0.4.30_1.1.67. Yes, when logging in to the router it shows my connection as "good".
The problem is so intermittent I am not able to ping the router during the "hiccup."
I am using Comcast's Domain Name Severs at 75.75.75.75 and 75.75.76.76
Today, I reset the router to factory defaults, reloaded the firmware (V1.0.4.30_1.1.67), reset the router to factory defaults again, then manually configured the router for my network setup. It's been up for 1 hour 45 mins with stable connections and proper rendering of emails. So far, so good! If it hiccups again, I'll try the different DNS's you mentioned.
Thanks for the reply.
Hi tucsontico,
As suggested, please try using a different DNS for us to isolate the issue properly. If the issue persists while using a different DNS, please downgrade the routers firmware for us to check if it works on another firmware version.

I switched DNS servers to the OpenDNS servers (208.67.222.222 and 208.67.220.220) after I had some dropouts again after re-installing the most current firmware. This swap appears to have stablized my LAN connections.
While switching DNS servers seems to have stabilized my LAN, I noted my wife's iMac was still having occasional poor page rendering (no pics loading, wrong fonts, etc.). On a whim, I had her disconnect the ethernet cable and turn on WiFi instead. Even though it has only been a few hours, that appears to have solved the problem. I inspected the now disconnected ethernet cable and discovered it is a Cat 5E cable versus all the rest of my hard wire connections are Cat 6 shielded cables.
I now believe the issue with her poor webpage rendering and slow performance is a bad Cat 5E cable. I will procure a proper length Cat 6 shielded cable tomorrow and recheck her connectrivity and page rendering. Hopefully, this will solve this annoying issue once and for all.
Thanks for your continued help!
