Review: Great and works well - This is a great little device and works so well. I needed internet boosting to a cabin in my garden and previously I was only able to achieve 1 bar of signal if that and it would always drop out. Since installing this, I have now got full bars of WiFi and it’s fast too, which has been amazing. It was super fast to set up, only took about 10 minutes and it’s generated a strong signal ever since. For the price, I’d highly recommend. Review: A WiFi 6 extender that does go through walls - there is a compatibilty issue and solution provided - Setup: When you first set this up, you'll need upgrade the firmware to the latest version, then i factory reset (ideal to do this with new firmware), then start the process again. Speed: This is a beast, having used a TP-Link RE220 and RE330, they're limited to WiFi-5 standard and each have a 100mpbs RJ45 port (that can provide networking in repeat/extend mode or be used for backhauling when in access point mode), the ME80X is WiFi-6 and has a 1Gbit (1000mbps) port. The ME80X goes through multiple brick walls, the ME80X in access mode it's like standing next to the router when in the next room (connected to the router via network cable at 1000mbps (1gbit)) Word of caution, if you have an eco home, the external walls are often lined with foil sided insulation boards, your house will be like a faraday cage, as we discovered when setting one up inside his house, internally no issue, limited WiFi just metres outside (this isn't a fault with this device). As my house is brick, at the end of the garden i was getting 33% of the speed i was getting indoors next to the router, 110mpbs of the 330mbps i can get via my 5G router (when in access mode). Compatibility Issue Warning and Resolution: It was seemless pairing with my 5G router (2.4Ghz and 5Ghz have separate SSID's), however, we had a compatibility issue with my friends BT Super hub 2 with the ME80X he bought too. This is due to the fact the BT router (like many ISP routers) uses 1 SSID for both 2.4Ghz and 5Ghz (can't be separated), when initially setting up the ME80X, you get the option to connect to the 2.4.Ghz and 5Ghz bands on the router, in the ME80X you assign the same router SSID to both 2.4Ghz and 5Ghz connectivity bands and assign your own extension SSID to the 2.4Ghz and 5Ghz (don't use the same SSID as the router if you use more than one extender/acccess point with the same SSID as the router (unless in mesh mode), this could cause extenders to try and connect to each other if the router loses WiFi (off-line). Once we rebooted after config, the ME80X couldn't connect to the BT router (no internet), the issue was with the band/channel mangement on the BT Router, you have to disable "smart connect" in the router admin WiFi management and assign a fixed 2.4Ghz band channel (1, 6 or 11) and a fixed 5Ghz channel (36, 40, 44, or 48), then after a reboot of the router and ME80X, this allowed to surf the internet via the ME80X, and allowed us to continue to switch it into access mode (can't be done until extend mode is configured), once i was able to configure access made, i logged back into the BT router admin and reenabled "smart connect" and alll back to normal. The key point is, repeaters like this want to connect to the 2.4Ghz and 5Ghz bands, as some routers use a single SSID, you'll likely have to diable any band/channel mangment within the router and assign fixed chnannels (reboot), as in my case, once we were in Access Mode (direct link back to the router via networking cable) we could enable the band/channel mangement (AKA smart connect) and use the access point like it is it's own WiFi (router) (only reaon i bought it was for 1Gbit port WifFi-6 access mode that goes through walls) Friends is working fine too as an access point via his BT router once the smart connect was enabled again (always reboot afterwards to ensure they connect after reconfig). So far so good! ## Features - Ultimate Signal Coverage: High Speed and High range coverage to boost the dual band wireless coverage in all WLAN networks; Extend WiFi signal to dead zone with 1300 Mbps on 5 GHz and 600 Mbps on 2.4 GHz - 2 Modes Versatility: Wi-Fi Extender has Ethernet Ports with Repeater/AP, can easily turn your wired Internet connection into a wireless access point; Home users will set it up in one of two ways: Range extender (it connects to your existing wireless network wirelessly and enhances/extends the signal) or Access Point (it connects to the Internet or your existing network via Ethernet and then broadcasts the wireless signal - Universal Compatibility: Fast Ethernet Port-Compatible with any wireless network devices and wired devices; You can online games, video conferences and even play 4K high-definition video anytime and anywhere at home - Reliable Connection: This Wifi extender can maximize network security, ensure your network safety problem.

So far so good! ### ⭐⭐⭐ Range is good but speed is limited to 30 mbps max, not good for multiple devices or streaming. *by A***R on 2 July 2026* the range extension is good, however this is a single band extender, works on 2.4 ghz only. it uses half duplex, in english this means it has to listen for traffic then send it to the router on the same channel so it will not be able to reach the nominal advertised 300mbps speed. real world speeds are about 30 mbps. In my case I have 150 mbps internet speed on my router, using this extender (ME12 300mbps) I get a good stable range but the max speed I can reach is 20 mbps. I will return it back as I need to extend the range and maintain a higher speed for tv streaming. Regarding setup, I set it up using the WPS feature, setup was quick and easy, pressed the wps button on the router, powered on the extender and pressed the WPS button on the extender and it was able to configure itself. the caveat is this way it creates a new network with the suffix _EXT, you will need to look for it on your device and connect to it, it will need the same password for your wifi to connect, the password is the wifi password configured on your router. You will need to do the connection bit once per device, i.e. to connect a cell phone look for the _EXT wifi network, connect to it, enter the wifi password. to connect a TV, repeat the steps on the tv. Another user pointed out that renaming the extender network and removing the _EXT suffix to keep the name exactly the same as the original wifi name allows connecting to the network seamlessly, that should work if you are extending the connection to the garage and are happy to be on 20mbps and don't want to manually select the extender network, however with in the house if the device changes from the original fast wifi to the extender network you will end up with the lower speed and you won't be able to tell, so my advise is to keep the _EXT suffix if you are using this device. I did some reading and found that the (Mercusys AX1500) seems to be the one that will meet my needs, it is a dual band extender, supports 2.4 and 5 ghz & wifi 6, it should be able to provide a 5 ghz wifi network for the endpoint devices like a tv or a cell phone within a 5-8 meter distance within direct line of sight from the extender, while the extender itself can maintaining a connection to the router on 2.4 ghz, using the two bands simultaneously should be get me into the 80 - 120 mbps speed zone which would be good enough for my streaming need. ## Frequently Bought Together - MERCUSYS ME50G AC1900Mbps WiFi Extender Booster, Internet Booster, Ethernet Port, EasyMesh, High-Gain Antennas, Access Point,WiFi Repeater,TP-Link WiFi Extender,App Control Easy Setup,UK Plug - Ercielook CAT8 Ethernet Cable 0,5m 1m 2m 3m 5m- High Speed Shielded Flat Internet Cable, Weatherproof S/FTP UV Resistant for Router/Gaming/Modem - 0.5m (White) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/593450058-mercusys-me50g-ac1900-wifi-extender-booster-wifi-booster](https://www.desertcart.jp/products/593450058-mercusys-me50g-ac1900-wifi-extender-booster-wifi-booster) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-13*
