Network speed fluctuates unpredictably
Network speed fluctuates unpredictably
Every few months, some devices linked to my router via Ethernet experience a sudden drop in speed—from around 300Mbps down to about 100Mbps, then back up to roughly 8Mbps with a 5Mbps increase. This happens while keeping strong Wi-Fi performance (around 150 Mbps on the 5GHz band). The only solution I’ve tried is restarting the router, which works but isn’t ideal since I host services and can’t reset it often when the connection fails. It seems Ethernet is the weak link here. I wonder if this points to a router issue or a memory problem. Should I replace the router? Here’s some info for reference: Model AC750 Wireless Dual Band Gigabit Router, firmware 0.9.1 5.0, version 170207. Country of origin: New Zealand.
I initially thought the router might be the issue. Over the years I've adjusted my routers and cable modems, adding fans to improve performance. The extra cooling helped maintain stability and consistent speeds, particularly during long downloads. Another solution I tried with my in-laws involved a vacation timer. They needed to restart it occasionally for it to function properly, so I connected it to a timer that would turn the power on at night when no one was using it. This ensured the device stayed reliable throughout the day.
