MERCUSYS MR80X
8.5/10Best Budget
The MERCUSYS MR80X is a dual-band AX3000 Wi-Fi 6 router with four external antennas and three gigabit LAN ports. It suits flats and small homes on fibre plans well under a gigabit, where a low price matters most.
Basic settings and no 2.5Gbps ports, so it will hold back a multi-gig plan

Level with the ASUS RT-BE86U
The ASUS RT-BE86U and the MERCUSYS MR80X score the same, so either is a safe pick. The ASUS RT-BE86U goes first because it is the newer design.
About the MERCUSYS MR80X
The MR80X is a dual-band Wi-Fi 6 router rated at AX3000. Mercusys lists signal rates of 2402Mbps on 5GHz and 574Mbps on 2.4GHz, and says these are physical maximums, not real throughput. Four fixed 5dBi antennas sit on the body, with beamforming. Inside is a Qualcomm chipset with a 64-bit dual-core CPU. It also supports MU-MIMO, OFDMA, BSS Coloring and Target Wake Time.
Wired connections are one gigabit WAN port and three gigabit LAN ports. There is no USB port, no 2.5Gbps port, and no wall-mounting holes, according to an independent review from Blacktubi. Security covers WPA2 and WPA3-Personal, though WPA3 needs a device that supports it. It runs a VPN server (OpenVPN and PPTP), guest networks on both bands, QoS, Smart Connect and an access point mode. It handles up to 256 devices across both bands.
Setup runs through the Mercusys app. Parental controls in the app cover user profiles, online time limits, website blocking and an internet pause. Blacktubi found them basic, and the firmware is TP-Link's with Mercusys branding. The box holds the router, power adapter, quick installation guide and an Ethernet cable. The router measures 208.8 x 171.6 x 41.7mm.
What owners report about the MERCUSYS MR80X
Owner feedback is mixed rather than glowing. Many report fast everyday Wi-Fi, stable running over months, decent coverage through several rooms and low ping in games. Several say it pairs easily with other Mercusys or TP-Link units. The value for money comes up often.
The complaints are consistent too. Range on 2.4GHz is weak for some, and wireless speeds fall well short of a fast wired plan. A fair number mention Wi-Fi drops that need a power cycle, a slow admin interface, and the unit running warm. Some phones do not see 160MHz channels or the higher 5GHz channels. A few owners had trouble setting up EasyMesh with satellite units, and one found their firmware version was too old for it.
Owners on the OpenWrt forum also note that the MR80X has been sold in different hardware revisions, some with Qualcomm chips and some with MediaTek. Check the label if you plan to flash third-party firmware. Feedback specific to the UK unit is thin, and most of what is above comes from owners in several countries.
Who the MERCUSYS MR80X suits
Buy it for a flat or small house on a fibre plan of around 500Mbps or less, or as a cheap upgrade from an older Wi-Fi 5 router. It is simple to set up from a phone, which helps first-time buyers, and the VPN server is handy if you want remote access to your home network.
Look elsewhere if you have a multi-gig plan or want 2.5Gbps ports, a USB port or more than three wired devices. The TP-Link Archer BE3600 has 2.5Gbps ports and USB 3.0. For a bigger home or a feature-rich app with stronger parental controls, the ASUS RT-BE58U is a better fit. If you are on UK copper broadband, the AVM FRITZ!Box 7530 AX UK has a built-in modem.
Questions about the MERCUSYS MR80X
Is the Mercusys MR80X good?
Yes, for the money. Owners praise its everyday speed, coverage and stability, and independent reviewers found decent performance. It has limits: three gigabit LAN ports, no USB and fairly basic settings.
Is Mercusys a good router brand?
Mercusys makes budget routers that owners rate mainly for value and easy setup. Blacktubi found the MR80X firmware stable, and it is TP-Link's software with Mercusys branding. Expect fewer advanced settings than premium brands.
Is Mercusys better than TP-Link?
Not generally. Blacktubi found the MR80X runs the same Qualcomm chip as the TP-Link Archer AX55 and performs similarly, but it has fewer extras than TP-Link's pricier models. Mercusys is the cheaper, simpler option.
What are the specifications of the Mercusys MR80X router?
It is a dual-band Wi-Fi 6 router rated AX3000, with 2402Mbps on 5GHz and 574Mbps on 2.4GHz. It has four 5dBi antennas, one gigabit WAN port and three gigabit LAN ports, and no USB port.
Does the Mercusys MR80X work with OpenWrt?
It depends on the hardware revision. The OpenWrt forum shows support for the MediaTek v3 is still going through review, while the Qualcomm versions are not properly supported. Check the revision on the label first.
What warranty does the Mercusys MR80X have?
Mercusys UK covers Wi-Fi routers for 3 years. The warranty only applies to products bought from an authorised Mercusys UK distributor or retailer, and you need proof of purchase and the serial number.
Other wireless router picks
The other badge winners in our wireless routers ranking.
Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 19 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
