Just over two weeks ago I unboxed the FiWi Booster and plugged it into my 120 m² flat to find out whether it could really rescue those two rooms where the Wi-Fi signal normally fades to nothing. After that I took it to a three-storey townhouse and ran the same tests.
After fourteen days packed with remote work, 4K video calls, heavy downloads and online gaming, I’ve gathered plenty of hard-earned conclusions.
So, what exactly is it?
Before getting into the weeds, let’s be clear about what a Wi-Fi repeater actually is. It’s a device that picks up the wireless signal from your router and rebroadcasts it with fresh strength, pushing the network into rooms where the connection was weak—or simply non-existent—before. Unlike mesh systems, which create several interconnected cells, a repeater acts like a smart “mirror”: it captures the original signal and reflects it, doubling coverage without forcing you to upgrade your internet plan.
What is FiWi Booster?
With that in mind, the FiWi Booster is a dual-band repeater (2.4 GHz and 5 GHz) capable of delivering up to 1,200 Mbps combined. It carries four fold-out external antennas that let you aim the signal wherever you need it most and provides two Fast-Ethernet ports for devices that demand extra stability. Its party trick is the plug-and-play installation: plug it into a midpoint outlet, press the router’s WPS button and, within seconds, the status light turns green to show it’s already boosting your Wi-Fi—no apps, no registrations, no fuss.
Design and first steps
Visually the unit is unobtrusive: matte white plastic, rounded edges and, on one side, vents large enough to keep air flowing. It tipped the scales at 134 grams and is no bigger than a compact laptop charger, so it won’t block the neighbouring socket.
The setup ritual took less than a minute. I plugged it into a midpoint between the router and the “dead zone”, pressed WPS and after twenty seconds the LED flipped from red to green. A new network called “MyHome_5G_EXT” appeared.
For the curious: a sticker on the shell shows the internal IP (192.168.10.1) and the factory password, in case you want to change the SSID, encryption or channel.
Real-world performance
To see what it could do, I tested it in two very different homes:
First, my flat: the ISP router sits about nine metres and two hollow walls away from the study where Wi-Fi is always weak. Without the repeater I barely saw 40 Mbps in there; the moment I hooked up the FiWi Booster, the speed jumped to roughly 80 Mbps and the 5 GHz network leapt from 90 to more than 200 Mbps. Video calls stopped freezing and 4K movies streamed without a hiccup.
Second, a three-storey townhouse. The router lives on the ground floor and the signal used to reach the attic with only two shaky bars at best. By placing the repeater on the landing I could watch Netflix in 4K up top while, downstairs, an 80 GB game downloaded with no complaints from anyone. Even on the Nintendo Switch the response time dropped from nearly 90 ms to around 50 ms.
Real-world coverage
Its four external antennas, which you can swivel however you like, broadcast a solid signal. In my trials the connection stayed stable up to about 12 metres even with two walls in between—more than enough to cover roughly 250 m² in an average home. If you have thick concrete walls or a metal door you may need to move it to a different socket, but you’ve got plenty of wiggle room.
Security and compatibility
It supports WPA2-PSK as well as WPA3-SAE, so modern devices can negotiate the most robust protocol. It doesn’t bundle parental controls or quality-of-service features because those settings live in your main router.
On top of that, it’s compatible with the vast majority of routers on the market—I tested it with an ISP router, a Wi-Fi 6 unit and an older Wi-Fi 4 box with zero surprises—and it can also run in access-point or wired-bridge mode if you hook it up to the router via LAN.
Price and special offers
If your internet gasps for breath just when you need it most, the FiWi Booster may become your household hero. During the launch promo, with a 50 % discount and free shipping, the maker has slashed the price to €59.95, half of the €119.90.
The offer is, of course, time-limited and dependent on stock—it has sold out several times already—so it pays to move fast if you’re done staring at endless loading circles on your screen.

What other users say
With more than 1,262 reviews and an average rating of 4.7 out of 5 on TrustScore, the FiWi Booster has won over remote workers who need glitch-free calls, gamers who crave low latency and content creators who push hefty files to the cloud. Here are some of the most detailed experiences from everyday users:
Emily Johnson ★★★★☆ 4.6/5
“I spend eight hours a day on client video calls and, before installing the repeater, my studio was a festival of frozen faces and audio dropouts. The FiWi Booster fixed it in under a minute: I plugged it into the hallway, pressed WPS and the light went green almost instantly. Now I can wander around the whole flat with my laptop; even on the balcony the signal stays rock solid. Two weeks in and not a single dropout—and no bump on the power bill.”
Michael Baker ★★★★☆ 4.7/5
“I live in a duplex with solid brick walls and the router gets trapped downstairs. With the FiWi Booster sitting on the staircase I jumped from 5 Mbps to almost 60 Mbps in the bedroom. I play online shooters and my ping has been cut in half—the difference between losing to lag and winning a match. The unit is silent, cool and blends right into the wall—barely sticks out at all.”
Olivia Harper ★★★★☆ 4.9/5
“I’m a YouTube video creator and I upload 4K material almost daily. A 3 GB clip used to take over an hour to go up; now it’s done in twenty-five minutes. I also do live streams and need a steady bitrate—since adding the FiWi Booster I haven’t seen the ‘unstable connection’ warning once. I was impressed by how light it is and how fast support responded when I wanted to rename the extended network.”
James Carter ★★★★☆ 4.8/5
“My office is in the basement where I edit photos for international clients. The walls are concrete and Wi-Fi barely reached. I plugged the repeater into a garage outlet and instantly saw the speed jump from 3 Mbps to 70 Mbps. Even huge RAW transfers complete without stuttering. I also tried wired access-point mode: ran a 30-metre Ethernet cable and spun up a new network for my NAS boxes—flawless.”
Claire Mitchell ★★★★☆ 4.6/5
“In my 70 m² flat the signal collapsed in the kitchen; with the FiWi Booster I can now stream Netflix while cooking without a single interruption. Plugged it in, hit WPS and thirty seconds later it was working. It’s been running day and night for two weeks and stays cool.”
Who it’s for (and who it isn’t)
The FiWi Booster shines wherever you face general connection hiccups, a single dead spot or rooms far from the router. Large flats, duplexes, townhouses and even small offices can benefit from this device too.
If you need seamless roaming, full Gigabit ports or Wi-Fi 6/6E at maximum speed, you’ll have to look at pricier repeaters or mesh kits. But for most households on 600-Mb (or faster) plans, this extender is more than enough—and very affordable.
If you’ve been pondering changing your router, paying for more speed or calling a technician, you might just need this little white box to restore both patience and performance.
