Advice please on simple wifi booster/extender/repeater

I hope I won't get blinded by science, but I'm still trying to figure out the differences between a wifi repeater, extender, and booster - so it's hard to work out exactly how to phrase this request for advice!

Here's the picture. I have FTTC broadband, recently switched from Plusnet to Zen. So Zen supplies a Fritzbox router 7530 AX as part of the contract. After a few hiccups with the initial switch, it seems to be working well and reliably.

I/we are not heavy internet users - a little streaming, no gaming, no doorbell cameras etc, basically just home/domestic use for browsing, emails and occasional Zoom/Teams online meetings. So high-speed/high capacity is not crucial.

The router gives us a decent wifi signal within our - fairly modest and modern - house. No thick stone walls or metal barriers. Our laptops and mobile phones connect by wifi anywhere in the house, and the TV also connects wirelessly if we do occasionally want to see iPlayer programmes.

We are now looking at making more use of a separate log-cabin style carport/ summer-house in the garden just about 10-15 metres from our house. It has more or less clear line of sight to our router which is in an upstairs study, and it is - just about - within range of its wifi. We would like to be able to use laptops out there. This separate summerhouse has mains power. But putting in a cable (Ethernet) would be hideously complicated and costly.

So.... we are wondering if it would be possible to get some sort of simple, inexpensive wifi "booster" to connect with our Fritzbox router and give a better wifi signal in that garden location. The choice, and tech spec, of repeaters/extenders/boosters seems wide, and complicated. Zen offers a Fritz Repeater 3000, but it is not cheap to rent (£9 per month) and it sells retail at over £200. We'd like to buy some kind of wifi booster that will work with our Fritzbox 7530 router, be simple to set up, and will give us a rather better wifi signal in the garden room. Ideally for not more than £50, if that's not unrealistic.

Any and all suggestions gratefully received - and technical/practical comments on options and points-to-consider would also be welcome.

In reply to a post by br1anstorm:

I would say you really need a good external wifi access point but with only £50 your options are going to be limited at best. Others may think differently.

Is the router in your upstairs study as close as physically possible to the cabin? If you can place it in a window as close as possible to the cabin then you may find you get enough signal. If that doesn't give you enough signal then I am not sure where you would put a repeater as it would already be as close as possible and I am assuming you can't put a repeater halfway between the house and cabin. The only option then would be a repeater in the cabin potentially with a high gain aerial to pick up the best signal it can from the house - haven't done this myself so not sure what is available to provide for that.

A powerline/wifi extender

Not a recommendation, but something typically used in a situation like yours , the device uses the mains wiring , as you say the garden room has mains power , something like this are relatively cheap and easy to use

Personally, I'd run an external ethernet cable out to the cabin, and put a cheap wifi AP on the end. Something like the TL-WA801N. You can get external cable that can be direct buried if you want to cut costs, but conduit would be preferable.

You can get another Fritz!Box 7350 on eBay for less than £50.

As long as the signal from the original router is strong enough, you can set up a mesh system.

Thanks for those various suggestions offered so far. As I suspected, it looks there are several different ways of skinning the cat. I'd like to narrow it down a bit, and keep things simple.

In terms of the actual need and usage, I'm not setting up a complex network with multiple users and a host of appliances - so it's not like the kind of network that a hotel or corporate office might need. I just want to have a good wireless signal for internet access in one remote location (the cabin) that is just about at the limit of the Fritzbox router's range.

I am ruling out the option of running an external ethernet cable from my Fritzbox router out to the cabin. That is just too physically disruptive, running a cable downstairs to the ground floor, under that floor, and then out to the cabin either via the existing armoured-cable conduit (which is buried in a trench 2 ft underground) or in a new separate trench. Just not realistic or practical.

Which seems to leave two alternatives. One is some powerline/powerplug gizmo which is wired by Ethernet to the Fritzbox router, plugs into a mains socket in the house, uses the existing mains power cable to connect out to the cabin where a similar gizmo plugged into a mains socket delivers wifi (or an ethernet wired link) to a laptop within the cabin.

The other is some kind of device - a wireless access point or repeater?- which relies entirely on wireless links. A device which links directly by wifi to the router in the house and in effect re-transmits (and boosts) the wifi signal within the cabin, thereby extending the range of the wifi to enable a laptop tn the cabin to receive and connect reliably to the internet.

I've been looking at the TP-Link products, and am trying to figure out the difference between a Powerline Adapter (as per my first option above) , a Range Extender (like the RE550 AC1900) , and a Wireless Access Point (like the WA801N mentioned above). What are the pros and cons of each?

Cost is one consideration: I don't want to spend a large amount. And the other is signal-quality. I don't want to set up something which delivers a wifi signal in the cabin which is only marginally stronger that what the Fritzbox currently delivers at the limit of its range.

And I don't want something which significantly slows down the speed of the internet connection in the house or in the cabin (I don't understand the talk of "backhaul" etc, but that does seem to matter).

More thoughts would be welcome!

power line such as

https://www.currys.co.uk/products/tplink-tlwpa7517-a...

would be better along with an old router configed as a wireless access point(dhcp off and any nat settings off ). The main problem with cheap wireless extenders is that they can reduce bandwidth by up to half.

powerline though, is a tech that hasn't been updated for a few years now, and really in some ways is a dead tech but does work (it is variable in speed though). But would work for your situation.

If you can only just get a signal in the cabin then all a wireless repeater would do is repeat the signal at that same strength - it can't "boost" it. So, if you can only get 1Mb in the cabin from the router then that is all a repeater would be able to offer. Powerline is probably the best bet and you can get powerline devices that have built in wireless to provide the service inside the cabin. The only thing is Powerline is not something you can predict so until you try it you won't know if there are any potential issues or if the speed is good enough - I know people in the past have bought devices to test from Argos as their returns policy is generally pretty good (if you can open the box cleanly and repackage then you could return if it doesn't work well enough.

Something like this may do the job just fine (don't read much into the "speeds" they say as realistically these are fantasy.
