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:
- 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.
- 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.
b. Try to disable the QoS and Parental control on the Mercusys router.
c. Try a different Ethernet cable from the modem to the router, it’s
better Cat6 or above.
Case Two: Only wireless internet connection is slow
For possible resolutions, please see the following
-
Clear the wireless environment when running a speed test on your wireless devices. Make sure that there are no barriers between the router and wireless device running a speed test, and the best location is 6-9 ft from the router. It’s better to put the clients (like phones or computers) and router in the same horizontal plane.
-
Change the wireless channel and channel width on the Mercusys router.
You may refer to Changing Channel and Channel Width on a Mercusys WiFi router. (You may change 2.4G channel width to 40MHZ, 5G channel width to 80MHZ or 160MHZ) -

How to place your Mercusys wireless router for optimal reception and
performance
This Article Applies to:
MR90X MR80X MR70X MR50G AC12G AC12 MW305R
When you buy a router, you may be confused about the best place to put your
router for the best performance. This article will give you a few tips.
To better understand how a router’s wireless works, it’s important to first
understand how antenna signals are transmitted.
In general, our antenna signals are radiated vertically and outward from the
antenna. Therefore, in order for our antenna signal to be able to transmit
better, we need to pay attention to the following problems when placing the
router.
(Left) Scenarios that are not suitable for common-level use (Right) The router has better wireless coverage with horizontal use.
Tip 1. Place your wireless router in a central location.
The router’s impact on network speed is critical, so keep your router as close
to the center of the room as possible. Let it cover the surrounding signal as
evenly as possible so that the signal can be maximized. If your wireless
router is against an outside wall of your home, the signal will be weak on the
other side of your home.
Tip 2. Put your wireless router at a certain height
It is better to place the wireless router on a table or shelf and keep it at a
certain height so that the unidirectional antenna’s transmitting ability can
be utilized.
According to our actual situation, we suggest that the table should be about
1-1.5 ft so that the signal of the router is on the same horizontal plane as
the equipment you usually use.
Actual test case sharing:
For an actual height test, we placed the router at a height of 6 ft.
On Android, when we use the phone at a normal height On Android, when we hold
the phone up to a 6 feet level.
On iOS, when we use the phone at a normal height On iOS, when we hold the
phone up to a 6ft level.
The device will get a stronger wireless signal when it’s at the same altitude
as the router.
Note: The smaller negative number is better performance, eg, the Signal
Strength -32 will be better than the Signal Strength -50.
If you need to go upstairs or downstairs in your home, and the wireless needs
to cover different floors, we suggest that you turn on the antenna at an Angle
of 30°.
Actual test case sharing:
We did a test on the effect of antenna placement on horizontal radio. If your
router needs to be hung on the wall for use.
The antenna is placed vertically and then the wireless signal strength is
received by the iPhone in the horizontal plane. (Signal Strength -26)
The antenna is tilted forward at an Angle of 45°. (Signal Strength -35)
The antenna is completely horizontal. (Signal Strength -39)
So, if you only need to use it on the first floor of your home, or hanging on
the wall to use the router in a horizontal direction, we recommend that you
put the router antenna vertically.
Considering various requirements, we recommend the following antenna placement
methods.
Tip 4. Stay away from high-powered appliances
When the router transmits signals, the high-power electrical appliances, and
iron products may cause interference with Wi-Fi, so try to avoid microwave
ovens, weak current boxes, TV, and other electrical appliances.
Tip 5. Avoid obstructions
In order to keep it neat, a lot of friends put the router in a cabinet.
Putting it in the cabinet will block the signal, and the overall signal will
be weakened. Besides, the position of the router should not pass through too
many walls, because the walls are made of concrete, which is very strong in
shielding the router’s signals. The closer your wireless router is to these
obstructions, the more severe the interference, and the weaker your connection
will be.
Tip 6. Avoid overexposed areas
Keep it as cool as possible. Because long-term sun exposure will cause damage
to the router, which will affect the stability and the network speed.
Note: If you want to hang it on the wall, make sure it doesn’t shake or fade, because if the device is hit, it may be damaged and it won’t work properly.
Roubleshooting: Unstable connection on the Mercusys router
This Article Applies to:
AC12 AC12G MW305R MR90X MR80X MR70X MR50G
There are multiple factors that cause your internet connection to randomly
disconnect. Please read possible solutions below which may fix an internet
unstable.
Case One: Both the wired connection and wireless connection are
unstable
For possible solutions, please see the following:
- 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. If your computer cannot get a stable connection from your modem, it indicates the issue is on your modem or Internet Service.
- If there is no problem with the modem, please try the following tips:
- Check that the Ethernet cable is connected securely to the WAN port on your router and that the cable is not loose or attached poorly. To check if there is any problem with the Ethernet cable, replace it with another Ethernet cable and see if the issue persists.
- Try to change DNS servers on your router.
Please log into the web management page, then please click the Advanced>>Network>>Internet.
Then click the Advanced Setting, please change the DNS Address to the “Use the following DNS Address”, then please change the Primary DNS:8.8.8.8; Secondary DNS:8.8.4.4.
Case Two: Unstable wireless connection on TP-Link router.
Note: Please be sure that when the computer is connected to your internet
modem, the internet works fine without dropping. If the internet is not
stable, please contact your internet service provider to do some
troubleshooting. If it’s a modem/router, please contact your ISP to ensure the
internet line is good.
Please check whether the internet is stable or not when the computer is connected to the router with the Ethernet cable. If not, please refer to Case One.
Symptoms:
Wireless devices intermittently disconnect from the wireless network, while
wired devices are still connected and working fine.
For possible solutions, please see the following:
- Keep the router away from microwave ovens and other interference sources (refrigerators, ovens, Bluetooth devices, etc.)
- Reduce the number of wireless clients and optimize the router’s position.
- Try to adjust the orientation of the antennas for maximum performance. We recommend placing it as the same height with wireless clients and also placing its antennas at 45 degrees or 0 degrees (parallel to the floor) to the floor, which will be more effective. Since antennas always transmit weakly at the base, do not place your wireless client device at the bottom of Mercusys wireless device.
- If your Wi-Fi’s signal strength is weak, try moving the router to another location. Minimize obstructions between your router and your computer or other devices. Obstructions such as walls between your router and device can affect Wi-Fi signal quality.
- If your Wi-Fi signal is strong but the connection is still unstable, try connecting to the router’s 5G Wi-Fi. There are fewer interference sources on 5G networks. (If your router does not support 5G Wi-Fi, please skip this step.)
- Disable the smart connect on your router. (If your router does not support it, please skip this step.)
- If there are multiple Wi-Fi networks in the area, please change the router’s Wi-Fi channel and channel width. This avoids multiple Wi-Fi signals on the same channel, and reduces Wi-Fi interference sources.
You may refer to Changing Channel and Channel Width on a Mercusys Wi-Fi router. (You may change 2.4G channel width to 20MHZ, 5G channel width to 20MHZ)
- Upgrade your router to the latest version.
