Check what your line can actually do

Before you unpack your desk, find out what the copper or fibre line at your property is capable of. On many Scottish islands, the distance from the exchange or cabinet is the single biggest factor. A neighbour half a mile down the single-track road might enjoy 15 Mbps, while your cottage manages 2 Mbps on a good day. Test your speed at different times – early morning, mid-afternoon, and peak evening – and write the numbers down. Ask other remote workers on the island what they use and what they would change. If you are renting or buying, request a line check before you sign anything. The official UK broadband availability checker gives an estimate, but treat it as a rough guide, not a guarantee.

Pick equipment that makes the most of a weak signal

Standard ISP routers are often fine on the mainland, but they struggle when the signal arriving at your door is already marginal. Look for a router with a good modem chipset, external antenna ports, and the ability to lock onto specific mobile bands if you are using 4G or 5G. If your home has thick stone walls – common in island cottages – a single router in the hallway will not cover a home office at the back. A mesh Wi-Fi system with two or three nodes will spread the signal more evenly. Where possible, run Ethernet cable to your desk. It is ugly, cheap, and far more reliable than any wireless repeater.

• External antenna: A directional antenna mounted on a chimney or pole can turn a one-bar mobile signal into a steady 20–30 Mbps.
• Powerline adapters: Useful if your house has relatively modern wiring, but they can be hit-and-miss in older island properties.
• Uninterruptible power supply: Storms and power cuts are common. A small UPS keeps your router and modem alive for short outages.

Make the most of mobile broadband

For many islanders, a 4G or 5G router is the primary connection, not a backup. Start by testing each network with a pay-as-you-go SIM. Coverage maps are optimistic; the only test that matters is the one at your kitchen window. Once you find the best network, invest in a router that allows an external antenna. Position the antenna with a clear line of sight to the nearest mast – often over a loch or down a glen. A 5G router can deliver 50–100 Mbps in the right spot, but do not expect that everywhere. If you are beyond mobile coverage, a low-earth orbit satellite service may be your only option. It works, but latency is higher, so video calls can feel slightly delayed.

Keep video calls stable when bandwidth is tight

Video conferencing is the hardest test for any island connection. A stable 5 Mbps upload is more important than a fast download. Use a wired connection if you can. If not, connect to the 5 GHz Wi-Fi band and keep the router high and central. In your video app, turn off HD video and use a headset to reduce echo. Ask others in the house to avoid streaming or large downloads during your calls. Close background apps that sync files – cloud storage is a silent bandwidth thief. If your call still drops, try audio-only. A clear voice call is better than a frozen face.

Build simple habits and backups

Reliable remote work on an island is about managing expectations and having a plan B. Schedule large uploads and software updates for overnight. Compress files before sending. Keep a mobile hotspot with a different network as a failover – even a weak signal can carry an email. If you have a landline, treat it as a bonus, not a guarantee. Finally, join the local community broadband group if one exists. They often know about upcoming upgrades, shared masts, or grant funding for better equipment. The infrastructure is improving, but until then, a little preparation goes a long way.
