Issue with router not delivering ISP speed.
Issue with router not delivering ISP speed.
You meant that ISPs typically supply you with their own routers, which many users opt to use instead of setting up their own. While some prefer personal routers like the TP Archer, others must still connect via the ISP’s provided device in modem mode. Your own router manages connection settings and rules, while the older modem-only unit only handles incoming internet traffic. Have you confirmed with your ISP whether you’re still required to use their router in modem mode alongside your new setup?
It looks like your ISP connection and router are capped at 100Mbps. Verify that the Ethernet ports on the ISP device support 1Gbps and that you're using a reliable Cat5e or higher cable.
When using it in modem mode, it fails to function. Only the LAN operates correctly. They also didn’t supply a router.
Consider using another cable connecting the modem and router. The initial performance seems normal but then declines, indicating a problem with maintaining Gigabit speeds, eventually dropping to 100Mbit. Make sure the connectors are free of dust.
