Lag spikes occur when linked to a switch or secondary router
Hey! I see you've been troubleshooting this for a while now. Let's go through it again. You mentioned the main router is working fine when WiFi is off, but issues appear on Ethernet too. The problem seems to happen intermittently—about every 5 to 10 seconds, lasting a few seconds. You tried replacing the router with a switch and even switched the router to AP mode without fixing the issue. That suggests the hardware might be faulty or the cables are damaged. Since you can't find anything online, maybe it's worth checking the physical connections carefully—especially the Ethernet cable between the two routers. If you're still unsure, let me know what you find next!
This setup works well when handling two or more routers on the same network. Are the slowdowns coming from WiFi or Ethernet, or both? What are the specific models of your modem and routers? For the ethernet connection to router 2, which port is it connected to? Preferably, run router 2 in AP mode and connect router 1 via LAN-to-LAN, not WAN.
It works on both Ethernet and Wi-Fi, but Router 1 isn’t experiencing these problems. When set up as an access point, I connect my LAN to another LAN or WAN. However, I notice similar lag when switching from Router 2 to an Ethernet switch, which makes it hard to figure out the cause. If the issue is with the cable, I expected lag spikes to appear directly, but they don’t.
