Since the Mercusys MR70X supports the newer WiFi 6 technology, it will provide a better performance than Wireless AC routers in similar price range. If you happen to use a WiFi 6 supported smartphone, using a WiFi 6 router will give you significantly better performance.

The Mercusys MR70X is also a decent upgrade from the routers provided by the service provider. It will provide a stronger WiFi coverage and a more stable WiFi connection which will benefit older WiFi devices as well. I will recommend the Mercusys MR70X for those with less than 15 WiFi devices at home.

Quick Teardown

I also perform a quick teardown to look inside the Mercusys MR70X. Nothing spectacular but at least there’s a decent chunk of heatspreader acting as a heatsink to cool down the router. 

WiFi Performance Test

I will be testing the WiFi performance on my 1Gbps Internet connection with 500Mbps upload speed. My test device will be my laptop and my iPhone, both with WiFi 6 support. My laptop is using the Intel AX200 WiFi 6 adapter. The speed you get may vary depending on the receiver you have.

5Ghz WiFi Performance

On a short distance, the Mercusys MR70X can reach around 650Mbps on my WiFi 6 supported iPhone.

The 5Ghz WiFi performance after 2 walls is still decent. It is only slightly slower compare to the Archer AX10 that I have tested in the past. However, this speed is probably good enough for a lot of people especially those on a lower Internet subscription.

2.4Ghz WiFi Performance

The 2.4Ghz signal is surprisingly decent for the price. The signal is stronger than the Archer AX10 and being more stable in overall. However, I am staying at an apartment with severe 2.4Ghz interference so you will probably get a better 2.4Ghz WiFi speed than me.

Firmware and Features

Mercusys MR70X runs the same firmware as TP-Link routers which mean it will at least be stable and reliable. The interface is fast and reponsive throughout my test. I find the router to be pretty stable and I do not encounter any firmware crash or restart when testing this router.

While the software is basic, it does have the usual function expected from a WiFi router. There’s guest WiFi, dynamic DNS, VPN server and more. I also tested the IPV6 function and manage to get 10/10 on Unfortunately, it does not come with a repeater mode which will be handy to some users.

Security wise, the Mercusys MR70X support the latest WPA3 wireless security which is very surprising to us. Cheaper routers typically skip on security features but it is good to see Mercusys got the priority right. However, do not enable WPA3 unless you are 100% sure your devices support it.

Closing Thoughts

Mercusys MR70X is a decent budget router. It has decent WiFi coverage for a smaller home and decent WiFi speed. I will recommend Mercusys MR70X for those staying in a smaller property under 1000 square feet with less than 15 WiFi devices.

If you are shopping for a cheaper wireless router, the Mercusys MR70X is probably a better choice than most cheaper Wireless AC router due to WiFi 6 capability. Comparing to similar WiFi 6 router, I will recommend buying the Mercusys MR70X over the Archer AX10 due to the better WiFi 2.4Ghz performance.
