WiFi Setup
Last updated:
A surprising number of Swedish households put up with mediocre WiFi for years when the fix is straightforward. The pattern is familiar: the router from the ISP sits where the fibre enters the apartment, usually a hallway or a corner, and signal falls off sharply two rooms away. Streaming stutters in the kitchen, the work-from-home laptop drops calls in the bedroom, and the kids blame the speed when the actual speed at the router is fine. Real WiFi problems are almost always coverage problems, not speed problems.
The right fix depends on the space. For apartments up to about 70 square metres with reasonably open layouts, a good single router placed centrally (not in a cupboard, not behind a TV) typically covers the whole unit. For apartments 70–120 square metres, or anything with thick concrete walls dividing rooms — extremely common in Swedish miljonprogram-era buildings — a mesh system with 2–3 nodes is the practical answer. For houses, mesh becomes essential, and the placement strategy matters significantly: nodes roughly 8–15 metres apart, in line-of-sight if possible, one per floor for vertical coverage. WiFi 6 (802.11ax) and WiFi 6E are mature in 2026 and worth specifying for new installations; WiFi 7 exists but offers marginal real-world gain for most home users.
The ISP-provided router is usually the weak link. ComHem, Telia, Bahnhof and Tele2 ship functional but unremarkable hardware. Replacing with a good mesh system (TP-Link Deco, Netgear Orbi, Google Nest WiFi, Asus ZenWiFi, Eero) routinely resolves coverage problems that people assumed were speed issues. The catch is configuration: the ISP router often can't be fully removed (fibre termination), so the mesh needs to operate in access-point mode or the ISP router needs to be bridged. A competent installer handles this without drama; attempting it yourself requires some networking knowledge and a willingness to call the ISP if something goes sideways.
Setup service from a local technician typically includes site survey (measuring signal in different rooms), router/mesh placement, SSID configuration, guest network setup, parental controls if requested, and verification testing. The value is in getting it right once rather than iterating through four different positions over six months.
What does it cost?
WiFi setup service in Sweden runs 1,500–3,500 SEK for a single-router installation in an apartment, including device supply if needed (basic router 800–1,500 SEK, good router 1,500–3,000 SEK). Mesh system installation runs 3,500–7,000 SEK for a 2–3 node installation in an apartment or small house, with mesh hardware (TP-Link Deco, Asus ZenWiFi, Google Nest WiFi) at 2,500–6,000 SEK depending on node count and model. Houses with more complex layouts or requirement for wired backhaul (ethernet cabling between nodes for best performance) can run 7,000–15,000 SEK. Hourly rates for configuration-only work range 700–1,200 SEK. Most installers offer a site survey separately at 500–1,000 SEK if you want a diagnosis before committing to hardware.
How to choose the right provider?
Start with a clear description of the problem. "WiFi is slow" is less useful than "video calls drop in the bedroom but work in the living room, the study signal meter shows one bar". A good installer does a quick site survey first — walking around with a phone app measuring signal strength — before recommending hardware; anyone who proposes a specific product before seeing the space is selling rather than fixing.
Ask what approach they'll take before buying anything. A mesh system is right for most multi-room spaces but overkill for a small studio; a powerline adapter is a cheap fix for reaching one difficult room. Ask whether they'll configure the ISP router to bridge mode or leave it dual-broadcasting (dual broadcasts can cause real headaches with roaming). Finally, confirm they'll secure the network properly — WPA3 or WPA2-AES, no WEP, strong default passwords changed, guest network separated — and that they'll label and document the setup so you know your passwords afterwards.
Frequently asked questions
Do I need a mesh system or is a single good router enough?
For apartments up to 70 square metres with open layouts, one well-placed router is often enough. Past that, or if your apartment has concrete walls, mesh almost always outperforms a single router, even a powerful one.
Can I keep using the ISP router?
Usually yes — most installers keep the ISP router for the fibre termination and put the mesh or new router behind it in bridge or access-point mode. This avoids ISP support complications.
Will WiFi 7 make a noticeable difference?
For most home users in 2026, no. WiFi 6 or 6E is still the sweet spot — WiFi 7 matters for specific high-bandwidth scenarios but rarely changes the experience of streaming, video calls and normal browsing.
