RBK753 router keeps losing Internet connection, shows magenta ring
Hello — hoping someone can help. I bought the RBK753-100NAS setup from Costco yesterday afternoon and set it up, and in the 16 hours it’s been running, I’ve lost all Internet connectivity twice. The ...
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Is the Orbi system operating in Router or AP mode?
Any Wifi Neighbors near by? If so, how many?
Has a factory reset and setup from scratch been performed since last FW update?
FW = 3.2.15.25.
The modem is customer-owned, it's not ISP-issued, it's a Motorola Surfboard SB6141.
The Orbi is in Router mode.
Yes, I factory-reset the Orbi system, rebuilt the network and updated firmware.
In terms of "WiFi neighbors," do you mean how many other networks are available in the area? There are 3-4 others depending on whether my devices can pick up the one across the street.
Has the ISP confirmed that the signal to modem is to spec? The result of the RBR loosing the connection with the modem would be only a couple of items, ISP service signal to the modem is spotty and not to spec or there are service interuptions, Try a different modem to see if the problem continues, LAN cable between the modem and router is bad. Or the router is in a noise envrionment and sometimes will auto reboot to try and find a better channel. Setting a manual channel sometimes helps with this. Haivng other wifi signals near by can be problematic from neighbors or other in home wifi devices. Make sure the RBR is placed apart from the modem and other wifi or electronic devices. Usually 3-6 feet is good.
Have the ISP check the signal and line quality UP to the modem. As the ISP to check there logs to see if they reported any problems when this happens.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.Use CAT6 LAN cabling between the modem and RBR.
There aren't any problems with the Internet connection, it's the RBR that's the issue. I have a home-run RG6 line running from outside straight to the cable modem with no splitters installed, and my ISP has confirmed no service problems. Additionally, the second time this happened, I took the Ethernet cable (the one that came with the Orbi packaging) out of the RBR WAN port and plugged it directly into my computer's hub and connected easily to the Internet via hardline, so the line leading to the RBR was still active. I've placed it 4 feet away from other devices, but there seems to be something going on with the RBR that's causing it to suddenly decide it doesn't want to be connected to the Internet anymore.
