## Description

Buy

Review: Finally, Wi-Fi That Reaches the Bits My Router Gave Up On - Very happy with this Wi-Fi 6 extender. Setup was quick, connection is stable, and it immediately improved coverage in the rooms where my main router clearly stopped caring. Speeds are strong, streaming is smooth, and devices stay connected without random dropouts. It’s been quietly doing its job in the background, which is exactly what good networking gear should do. Two minor points: the unit is fairly large for a plug-in extender, and the setup app could explain a couple of steps more clearly. Neither caused real issues, just small speed bumps. Overall, solid performance, noticeable improvement in coverage, and no more walking around the house holding my phone in the air like I’m summoning signal from the sky.

### ⭐⭐⭐⭐⭐ Excellent value.
*by B***I on 26 January 2026*

This works very well, functional, sturdy, easy to set up.

### ⭐⭐⭐⭐ Great product, Terrible instructions.
*by C***S on 2 February 2026*

The range and strength on this is excellent, wifi 6 allows for fast internal communication. I've had this for a week and have seen no performance drops besides from when my router was having a hiccup. Cons: single button for reset/restart/WPS which is typical, but when pared with only one LED that doesn't accurately report which action is being undertaken, it's an issue. (Only during setup though). Extremely poor instruction manual, the ME80X is Easy mesh ready, the reason I purchased it, and there were no instructions on mesh set up, or any acknowledgement of it. (The package does come with extension instructions but this is not the same). For those needing help, BEFORE setup, (if already set up, hold the reset button for approx 10-20 seconds to ensure factory reset) login to your web based router manager (not accessible through app), turn on easy mesh from the left side bar, plug in the ME80X next to your router, once the LED is orange, press the WPS button on router and ME80X. On web manager scroll to the bottom, add mesh, search for WPS connection. Once it's been found it will automatically set up your mesh network. To confirm, ensure ME80X LED is solid green and that there is no "ME80X... Extension" when looking for available networks, should just be your home network visible. You can now unplug the ME80X and relocate to it's permanent location. Good luck, have fun.
