A garden room is an ideal way to create extra space — whether you're working from home, streaming your favourite shows, or hosting guests. But to make it truly functional, there’s one thing you absolutely need: a reliable internet connection.
So, how can you get WiFi in your garden room without dropouts, buffering, or frustration?
In this guide, we explore the best ways to get a strong, stable internet connection in your garden room — from budget-friendly DIY solutions to professional wired installations.
Why WiFi Can Be an Issue in Garden Rooms
While modern garden rooms are often built just a few metres from your home, your existing router may struggle to push a consistent signal through walls, windows and insulation — especially if the garden room is:
Positioned at the far end of your garden
Constructed with foil-backed insulation or SIPs
Separated by brick walls or fencing
Operating on older WiFi technology
If you want to work, Zoom, stream or game without issues, it’s worth investing in the right method to extend your internet.
5 Ways to Get WiFi in Your Garden Room
Here are the most effective ways to bring strong, stable internet into your outdoor space:
1. WiFi Range Extender (Repeater)
Best for: Garden rooms close to the house with decent signal already
A WiFi extender works by repeating your existing WiFi signal. Simply plug it into a socket halfway between your home router and your garden room.
✅ Low cost✅ Easy to set up❌ May suffer from speed drop-off❌ Weak if signal is already poor
2. Powerline Adapter with WiFi
Best for: Mid-range solutions using your home’s electrical wiring
Powerline adapters send your internet signal through your home’s electrical system. One plugs in near your router and connects via Ethernet, and the other plugs in inside your garden room.
✅ No signal loss over distance✅ Simple, plug-and-play❌ Requires same electrical circuit (may not work if garden room is on a separate supply)
3. Outdoor WiFi Access Point
Best for: Longer gardens or high-performance needs (work or streaming)
An outdoor access point is mounted on an exterior wall or post, broadcasting a strong WiFi signal over your garden. It connects to your router using a wired Ethernet cable and can be professionally installed for maximum range and speed.
✅ Strong, stable signal✅ Works in all weather❌ Requires some setup and configuration
4. Hardwired Ethernet Cable
Best for: Maximum reliability, speed and futureproofing
Running a dedicated Ethernet cable from your house to your garden room gives you the best possible connection. It’s ideal for heavy internet users, streamers, gamers or remote workers.
✅ Fastest, most stable option✅ Supports smart devices, security systems, etc.❌ Higher installation cost❌ May require trenching for underground cabling
You can also add a WiFi router or mesh node inside your garden room to create a strong signal for wireless devices.
5. 4G/5G Mobile Router
Best for: Garden rooms not near the house or with no home broadband
Using a mobile data router, you can access the internet via a SIM card. If you live in an area with strong 4G or 5G coverage, this can be a surprisingly effective standalone solution.
✅ Independent from home broadband ✅ Portable and flexible ❌ Relies on mobile signal strength ❌ May have data limits or variable speed
Professional vs DIY Installation
If your garden room is already built and you’re looking for a quick fix, a WiFi extender or powerline adapter may do the trick. But if you’re planning a new garden room, the best time to install proper connectivity is during the build. At CS Garden Offices, we can integrate data cabling and power supply at the design stage — ensuring your garden room is future-ready from day one.
FAQs: WiFi in Garden Rooms
Q: How far can WiFi reach outdoors? Standard home routers typically reach 20–30 metres, but walls, insulation and fences can reduce this significantly.
Q: Can you run Ethernet underground? Yes — with armoured or exterior-grade Ethernet cable. It should be buried in a conduit or protective sleeve.
Q: Can I boost WiFi without laying cables? Yes, using a mesh WiFi system or access point, though performance may vary depending on layout and signal strength.
