Garden Office

Hi all,

I'm after some advice from the collective. I've got 1Gb broadband to the house but on my current setup (mesh and home plugs) the connection isn't best out to my garden office.

Over home plugs I'm having to go through two consumer units (Garage and then to the Office) so by the time it gets there I'm getting 15Mb at the most, and it fluctuates a lot. Mesh is a little more stable but given the distance it's still only about 30-40Mb and with voice/video calls it's hit and miss.

Any advice to get faster? the only other option I've thought about is a CAT 6 cable to the switch in the office. For info, I'm on AV500 home plugs and it's a TP-Link P9 Mesh system

Thanks in advance

Get a network cable specifically for outdoor use then either bury it in some trunking fit for purpose or through the air haha you could use one of your mesh nodes to backhaul so you can have wired and wireless in there

One of my neighbours eldest was getting ready for his GCSE's but couldn't get peace in the crowded house. So he set himself up in a shed. Wifi was awful, so I ran a cable out to get him a full connection. I simply fed it through their old garden hose that I clipped to their fence. It is still there after all 4 kids grew up and had their time of GCSE study in the shed.

Sureky wifi wouls be better than the cabling you currently have?

Wifi would not be better than a cable connection.

I ended up installing some cabling for my Sky Q, the use of Wifi was too unstable.

30-40mb bandwidth is more than enough for video calls so your issue is either latency or packet loss or a combination of both.

Crucially you haven’t specified the distance from the equipment to your garden office……

1. As others have said put an external cable in
2. Depending on distance you may be able to mount an external access point

He's probably sorted by now, it's been 10 months.

Cabled connection to a switch in the garden building would be the best sollution.
You can get outdoor rated Cat6 cable and in a conduit would help too.


You can then use the wired connection or also add an additional wifi access point into the switch if you need Wifi access too down there.

They havent logged in since Dec 30th 2023 either.

must have been happy with the advice hahahaha

I hope things are sorted and working well.... Maybe someone replying to this thread will bring him back to tell us

Having engineered network links to dozens of garden offices, studios, and detached conversions across domestic properties, here is the physical and electrical reality of what happens on these runs—and the proper ways to link a garden building to a 1Gbps supply:

1. Why Powerline HomePlugs Choke Out to 15Mbps:
The reason your HomePlugs drop from 1Gbps down to a fluctuating 15Mbps is the electrical path. Powerline adapters modulate high-frequency RF signals (2MHz to 86MHz) over copper mains wiring. When you traverse from the house consumer unit through a submain, into a garage board, and then through another submain into the office board:
- Every RCD, RCBO, and surge protection device (SPD) acts as a high-frequency low-pass choke filter, heavily attenuating the RF carrier signal.
- If the circuits sit across different phases (in larger homes) or different RCD neutral bars, the signal has to rely on inductive cross-coupling, resulting in massive packet drop and latency spikes that cripple video conferencing.

2. Physical Solution 1: External Solid Copper Cat6 (or Pre-Terminated Fibre):
Running a dedicated physical link is always the benchmark for a 1Gbps connection:
- Trenching Cat6: Run black external-grade, UV-stabilised solid copper Cat6 with a tough polyethylene (PE) jacket (never internal PVC or copper-clad aluminium / CCA). Pull it inside 25mm black MDPE water pipe or flexible conduit buried at least 450mm deep to prevent future spade strikes.
- The Earth Potential Trap (BS 7671 Warning): If your garden office has its own earth electrode (TT earthing) while the main house is on PME (TN-C-S), running shielded copper network cable (STP/FTP) with grounded drain wires can bridge the two earthing systems. This creates circulating earth currents or touch-voltage hazards. Always use unshielded UTP for outbuilding copper runs.
- Pre-Terminated Ruggedized Fibre (The Ultimate Fix): For runs over 30–40m or where earth loop isolation is needed, a pre-terminated 2-core armoured single-mode (OS2) fibre cable costs around £30–£40. A pair of £20 Gigabit SFP media converters at each end gives complete galvanic electrical isolation, immune to lightning surges and electrical noise, with full symmetrical 1Gbps bandwidth.

3. Physical Solution 2: 5GHz / 60GHz Wireless Point-to-Point Bridge (Zero Digging):
If lifting patio slabs, digging across landscaped lawns, or threading conduit is impractical:
- Deploy an active wireless PtP bridge pair (like Ubiquiti NanoStation Loco 5AC or MikroTik Wireless Wire).
- Mount one small unit externally on the house fascia/eaves facing down the garden, and the matching unit on the office roofline.
- Powered via standard passive PoE from inside, a 5GHz bridge provides a reliable 450Mbps+ link with sub-2ms latency, while 60GHz units deliver full uncompressed 1Gbps wire-speed across the garden with zero dropped frames on Teams or Zoom calls.

4. Inside the Garden Office:
Bring the incoming cable or bridge into a 5-port Gigabit switch, and plug your desktop/docking station into an RJ45 port. Then hang a Wi-Fi 6 Access Point (or a mesh node configured in AP mode with Ethernet backhaul enabled) off the switch to blanket the room and immediate garden with high-speed Wi-Fi.
