My internet plan is 500 Mbps down/ 100 Mbps up, but when I do a speed test only can reach 92 Mbps down /91 Mbps up (using a LAN cable connected to my router and doing the speed test). I tried rebooting my router and tried to replace the other cat6 cable, but the result was still the same. I called the Unifi technical assistant for help, but they kept telling me that the modem was fine and could handle the 500mbps speed. I did google research and found that my modem LAN ports only support 10/100mbps. Now I want to change the modem to see if I can reach 500mbps download speed to know whether it is the modem problem or the router.



My router show the WAN port only have 100mbps.
