Mercusys Halo H50G Review scaled

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

I wasn’t overly impressed with the Mercusys Halo S12. While it is incredibly cheap, the overall specification and performance reflected the price.

The Mercusys Halo H50G is a significant upgrade in specification and what I would personally recommend as the minimum specification you want from a Wi-Fi mesh system.

With many homes being able to access Internet speeds well over 100Mbps, I don’t think 100Mb Ethernet ports are acceptable. I appreciate this may not be that important to everyone, but as far as my recommendations go, I think Gigabit Ethernet is essential.

The Halo H50G has this important upgrade, it has three gigabit ports vs two 100mb on the H12.

The Halo H50G also upgrades the Wi-Fi speeds to 1300 Mbps on the 5Gh and 600 Mbps for 2.4 GHz. I would therefore assume the Wi-Fi radio is 3×3 rather than 2×2. It is unlikely you will ever connect at 1300 Mbps, but it gives you a bit more headroom and could possibly help with the backhaul.

Of course, all this comes at a cost. The Mercusys Halo H50G is £120 vs £50 for the Mercusys Halo S12

I set this up using the Mercusys app. When I reviewed the Halo S12, everything was via the local web interface, so there has been a bit of improvement, but not lots. The set-up was a relatively unpleasant process compared to most Wi-Fi devices.

It took multiple attempts to detect the first Halo H50G device. Then when it had detected, it wouldn’t connect to it, forcing me to hit retry. Eventually, it advised me to connect my phone to the open Mercusys SSID that was being broadcast, and I was finally able to set it up.

The app has some appalling reviews online, so it is not just me that has experience issues.

Thankfully, once I had the initial router set up, everything else worked without issue. Within the app, there is a little plus button that can be used to identify the satellite devices. It took a while for them to be found, I was expecting it to fail, but it found them both the first time.  


I have a moderately large 4-bed brick built semi with internal brick walls, like many UK homes. The main device is in my office, which is central to the home and upstairs. I then have a satellite in the front living room and one in the kitchen, the two rooms furthest away from the primary router.

I first tested the main Halo H50G router by itself with no satellites attached to get an idea of the maximum speed and overall range.

Connecting to on my desktop PC in close range to the Halo H50G I was able to achieve a download speed of 461Mbps, and my Pixel 6 managed 443mbps.

Mercusys Halo H50G iperf

Using iPerf on the desktop, I achieved a throughput of 627 Mbits/sec. This is actually a very good result as far as Wi-Fi 5 devices go, being higher than many of the recent systems I have reviewed.

For comparison, the Mercusys Halo S12 managed 70Mbps with Speedtest, which was slow enough that it wasn’t working testing with iPerf.

Moving around the home, I was surprised to find it provided a reasonably good signal throughout my entire home. In the kitchen, this was 199Mbps, and in the front room, this was 112Mbps.

Connecting the satellites improved the speed a bit, but not massively so. One issue here is that this is a dual-band mesh system, so the backhaul is shared, causing 50% signal loss.

In the front room, this speed increased from 112Mbps to 184Mbps

In the kitchen, the signal was extended far enough that I was able to connect in my garage/gym, which is across the garden. In here I achieved 158Mbps

Price and Alternative Options

The Mercusys Halo H50G is priced at £120 on various sites, such as Currys, for the triple pack. Unusually, Amazon is the most expensive at £150.

Buy from Currys

The triple pack Google Wi-Fi is discounted at just £135, though it is frequently at full RRP for £190

The Tend MW12-3 tri-band system is currently £160 but £214 at full RRP. It costs more, but the tri-band design will offer significantly better performance.

The Tenda Nova MW6-3 is £95, or £117 RRP. It has a lower Wi-Fi spec than the Halo 50G and only 2 gigabit ports.

The TP-Link Deco M4 is almost identical to the Tenda MW6-3 is specs and is priced at £116.93 but it regularly sells for under £100


The Mercusys Halo H50G is vastly better than the Mercusys Halo S12 I previously reviewed. A dual-band Wi-Fi 5 system with gigabit ports is the minimum I’d ever recommend.

The Android app and set-up process are below average, but once set up, I had no issues with the app, and you shouldn’t need to use it often.

The Wi-Fi performance was far better than expected. Connecting to the main Halo H50G, I was able to achieve speeds faster than many other Wi-Fi 5 routers or mesh systems I have used in the past, with most of those costing considerably more. The dual-band mesh performance is about average, there is a significant drop off in speed, but it provides good range and a very usable speed of over 150Mbps in every location on my property.

At £120, I have struggled to find anything that is better priced with the same specification and the Wi-Fi performance easily justifies the price.

Mercusys Halo H50G Whole Home Mesh Wi-Fi 5 System Review Rating


Initial impressions of the Mercusys Halo H50G  were not great, with a troublesome setup. It made up for it with superb Wi-Fi performance in relation to its cost.

  • Overall - 78%


  • Superb WiFI performance for the price


  • Poor app and setup process
  • Dual band mesh systems suffer from significant signal loss meaning you want the device that’s connected to your internet as central as possible to your house
