Nighthawk R8500 slow on Cox GigaBlast
Greetings, last week Cox installed the GigaBlast fiber optic 1 gig internet at my home. I'm running into an odd situation where their supplied R6300 router gets fast speed tests and my R8500 wil...
There are certain features that, when enabled, disable hardware acceleration. This forces the general purpose CPU to handle packet forwarding. Unfortunately, the CPU cannot handle Gigabit speed Internet service. These features include QoS, traffic metering, block sites, port forwarding/triggering, MAC address filtering (I think), MAC address cloning and maybe one or two other features. You should disable these and reboot the router. Then retry the speed test.
Oh, okay. Thanks microchip8. Still a bummer though, I like the access control / MAC address filtering option as an extra level of security.
The issue is what they don't print on the box. They usually have some * with a blip on speeds blah blah but don't say anything about how options could slow throughput.
