Hello everyone, I’m encountering an unusual issue and hope someone else has experienced this before. In my setup, the internet connects to the main room near the entrance, which has a functional coax connection. My office is roughly 70 feet away. Normally, wireless works smoothly on my devices, and the Wi-Fi speed easily handles the modem’s capacity. However, now I have five machines—storage server, VM server, development Mac, work laptop, and my gaming tower—all in the same room using Wi-Fi. The storage and VM servers already had a dedicated 10Gbps link, but data transfers between them are heavily limited by my Wi-Fi connection.
I resolved this by installing a wireless range extender, connecting its Ethernet port to a switch, and then linking all machines through the switch for internet and file sharing over wired connections. After restarting everything, the network functioned properly for 6 to 10 hours. But after reboots, DNS queries failed on the connected devices. Active local and internet connections—like RDP sessions or streaming—remained unaffected.
I’ve restarted both the router and extender, but the problem persists. I reset the router back to factory settings and reconfigured the Wi-Fi, yet the issue continues. I also tried a different router and extender, but that didn’t help. Changing manual IP addresses and DNS entries on the extender didn’t resolve it either.
It’s strange that DNS lookups randomly fail. I’ve checked the router and extender logs, but nothing stands out. If you’ve ever run a physical wire through the walls, you’ll know how tricky this can be in an apartment setting. Any suggestions or insights would be really helpful.
That's a good suggestion @DakotaWebber. I hadn't considered the DHCP lease duration. I plan to set it for three days starting from one day ahead and check if I can stay connected without issues. For a real switch, I'll need to lay a cable through the living area instead of going through walls, which should help with the constant interference.
It seems there might have been a misunderstanding. I’m not sure if you meant to ask about network issues with Wi-Fi extenders. Could you clarify what you’re experiencing?
The issue you're facing involves wireless range extenders generally. Their purpose is simply to broaden coverage, not to deliver stable or consistent performance. They function adequately for low-bandwidth devices such as smart and IoT equipment, but fall short for applications requiring full bandwidth utilization. This limitation stems from their half-duplex operation. Additionally, the effectiveness of a range extender diminishes with distance from the main signal source. Could you share the model or brand of your extender? You might find a wired connection more reliable if you already have a switch linking all your devices. Since you already have a switch, consider running Ethernet directly from the switch to the modem. The “wife-factor” is understandable, but if your tasks depend on it, you may need to accept some trade-offs. Ethernet doesn’t require passing through walls; it can be routed along walls or ceilings and secured with cable clips. Moreover, they are available in a wide range of colors, allowing you to blend them with your surroundings for better concealment.
Hello @Falcon1986 Thank you for the quick reply. I mainly require stable and swift connections only between my computers at my desk, not across the entire network. Everything is generally within a short distance of me. The one I’m currently using is a TP Link re450. https://www.tp-link.com/us/home-networki...der/re450/ I also have a Linksys router, possibly due to compatibility issues or multiple devices sharing an Ethernet port. Not sure if it’s built for that setup.
I believe there’s a misunderstanding about LAN traffic movement in your network. Even though everything is connected via the switch, communication with the main router still relies on your weak WiFi/extender setup. The issue isn’t about compatibility—it’s because wireless extenders often perform poorly for stable connections.
