The lights are affecting your internet connection.
The lights are affecting your internet connection.
It's time to upgrade, not crucial for this test. The problem isn't your Ethernet connection but the line leaving your modem. Likely it's routed near the lighting and hard to modify—probably Coax (cable). Since TVs use different frequencies, it shouldn’t interfere much. I see a few solid solutions: swap fluorescent bulbs for LEDs (business might offer discounts), reroute the coax cables (maybe not feasible), or shield your existing cable if it isn’t already. If the cable lacks shielding, get one with proper protection, though even shielded ones can face interference. Consider moving the modem to a different coax connection just in case.
My ceiling has a false ceiling above it, roughly three feet higher. It seems the internet operates on top of that false one—likely using standard commercial tiles with metal grids. My brother, who installed the internet, believes the issue lies in those metal grids where the cable is placed, which might explain why Wi-Fi still works but ping drops significantly when I turn off lights near my computer and router.
We discussed with my mom about switching to LED bulbs, though she intends to explore the idea further.
