The internet speed is affected by several factors, it's not always easy to
determine if it is because of actual problems with your Internet service,
clients, or because of issues with your home Internet network.
You can compare the results of your Internet speed test with what you are
actually paying for. If the results of the speed test don't match your Internet
plan, here are some tips and tricks for troubleshooting.
*Note: If the router is too hot may cause slow Internet speeds, this can
happen if it is covered with papers or perhaps a jacket, or is left exposed to
sunlight.
Case One: Both the wired connection and wireless connection are slow or
only the wired connection is slow
For possible resolutions, please see the following:
1. Disconnecting the Mercusys router from the modem (the piece of
hardware supplied by your Internet company), then only connect your
computer to the modem directly to test speed, If the Speed test result is the
same as the Mercusys router, it indicates the issue is on your modem or
Internet Service.
2. If there is no problem with the modem speed, please try the following
tips:
a. Unplug your modem. Then, unplug your router. Wait about 2-3 minutes
before powering on your modem. After your modem is fully powered,
restart your wireless router.
