R7800 Speed degrades over a day
Hello everyone. Here's my issue: I bought my R7800 about a year ago, when I saw that they were running fiber in our neighborhood. At that time we had 6Mb DSL and typically got 5Mb at best. As my old ...
Okay, since I finally got a day off, I sat down this morning and did the full 30-30-30 reset back to factory defaults. Only one device with hardwired connection. No other devices connected by wire or wifi. Ran speedtest.
Looks good so far. Browsed the 'net for about 30 minutes - just email and a couple news sites.
Back to the original problem. No Qos, no metering or Access control - all factory defaults. Firmware version V1.0.2.84
Any other suggestions?
If you have access to a different AC adapter it would not hurt to try. Be certain the replacement has the same voltage and at least the same or greater amperage.
Another option is to flash with Voxel firmware from here: Voxel
Well, I flashed it with the latest Voxel FW, and...no difference. This is a strange problem and I really don't think it's a router hardware issue.
As I said earlier, if I reboot the router, or just power it off, upon startup I run speedtest, from any of our PC's, I get full speed. And this is with only one device on the network and without clearing browser cache or anything - though I have done that with no discernable change. My primary Browser is Firefox, but Edge works just as well.
Fire up every PC, phone and tablet (which gives me 11 devices on network - 4 hardwired, and 7 on wifi), but do no browsing. Still full speed.
And what I am calling full speed is around 940Mb downstream, 970Mb upstream.
If I just stop at that point and do no browsing on any device - so far I went 3 hours doing nothing online from any device, I can run Speedtest from any device and get full speed.
Browse the 'net from any device, just 10 minutes or so, then run Speedtest, and I'm looking at 670Mb down, and 45-60Mb up...
I may just pull out all the stops and go DD-WRT and see what that does.
Could be your one PCs HW as well. If all other devices are working and to "full speed", then could be something else besides the router.
- I have the same problem with AX6000 and 2 XR1000s on gigabit fiber. I've tried upgrades, downgrades, and factory resets more times than I can count. On all 3 devices, up/down is ~940 at boot. After 30 minutes, like clockwork, it drops to ~670/70. I connect a much cheaper TP-Link AC1750, and speeds stay in the high 800s. Something has to be inherently wrong with how these routers are handling the speed or communicating with the fiber terminal.
