Upstream light blinking with no internet issues.

Upstream light blinking with no internet issues.

My Firmware Version is V4.6.5.8_2.0.54, and I have a v3 before, with both I had the upstream light blinking all the time. There is no connectivity issues, so, internet works fine, even with the v4 looks like better than before, but I see the upstream light blinking all the time and it's pretty annoying.

 

Download and upload speed are fine, I don't have disconnections, the Xfinity techinitian came to my house around three weeks ago to verify the signal, and line, and he said that there was no problems. No splitters between the modem and ISP service box, and several reboot (Power OFF the modem for more that 2 minutes and them back ON), and factory resets didn't change the current blinking light.

Re: Upstream light blinking with no internet issues.

Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch.

My Setup ISP SparkLight | Internet Cable 1000↓/50↑ CM2000 Modem | Wifi Router RAXE50 and R7960P(v.88) Router Mode and RBK752(v.2) AP mode | Switches NG GS105/8 |

Re: Upstream light blinking with no internet issues.

I didn’t try the factory reset after update the firmware. I’ll try it and put the result here.

Thanks!
