WiFi router fails to negotiate gigabit speed. Connection remains capped at 100mbps despite a 1000mbps link.
I'm dealing with an unusual AccessPoint, Router, and Modem setup from my ISP to expand Wi-Fi coverage. To improve performance, I purchased several TP-Link 5GHz routers, using one as the primary router and others as access points. However, my modem doesn't negotiate full gigabit speeds to the main router, limiting the network to 100Mbps. Connecting directly to the modem gives full 1Gbps. I'm unsure if disabling the ISP's internal DHCP server would help—should I disable it and rely only on the modem, or should I keep the modem as a router and use the TP-Link routers as access points?
Switch the ISP box into bridge mode to act like a simple modem. Use one TP Link router in router mode and the other in AP mode. Verify the specifications on the TP Link devices confirm 1 Gbps speeds on the ports. Ensure any remaining networking equipment supports 100 Mbps, otherwise you’ll need to upgrade.
I looked into Donut's recommendations and confirmed they were right—the routers do list 10/100 speeds on the LAN and WAN ports. I’m not getting much luck with those options. Now I’m avoiding spending over $500 on access points, especially for my office. Looking for affordable Wi-Fi routers around $100.
