I've been suffering with an issue causing my monitor to flicker for the past few months and have been avoiding fixing it because it's a pain and I figured it was a noisy power or speaker cable, but had some free time this week to troubleshoot and found that the culprit is the RBS850 unit mounted on my wall above the PC.
Bringing the device within 2-3ft of the HDMI cable causes massive interference, moving it out of the way resolves it.
For my setup I have an RTX3070 connected to an LG C3 OLED TV via a shielded HDMI cable, but have the same issue with 3 different cables, and with both of the RBS850 units that came in the mesh pack. I've heard of people having HDMI cable/electrical noise interfere with their WIFI, but never the other way around.
Has anyone else experienced this, or is able to see if they can reproduce the issue themselves? I've spoken to the retailer I bought these from to see if I can get a replacement but they're just directing me to buy more expensive HDMI cables. I've moved the AP somewhere where it isn't a problem, but would like to re-mount it so it's within reach of the UPS I have.
Any wifi router or system can cause some noise or interferences. Find some good shielded cabling and maintain a good distance between the wifi sources and cabling or devices. 3-6 feet in between is recommended.
Can try turning down the power output on the RBR as well:
Under Advanced Tab/Advanced Settings/Wireless Settings
