Travelling around the country, or indeed the continent, in a motorhome is generally a relaxing and enjoyable experience. However, one issue that can and-will puncture this pleasant pursuit is being unable to achieve a strong and reliable WiFi connection.
Motorhomes are unfortunately just inherently liable to struggle in this regard due to their robust metal exteriors, acting essentially as a faraday cage that weakens the wireless signals as they pass through to reach your phones and laptops.

Most campsites nowadays will be providing reasonable WiFi for guests to use with their devices, broadcasted by WiFi Access Points around the grounds. Being in closer proximity to one of these Access Points can alleviate the problem somewhat, but that’s not something you can really count on and even then, it’s not a strong solution.

Why accessing WiFi offered by a Campsite is tricky for Motorhomes:

• Metal exterior acts like a faraday cage, weakening/blocking incoming WiFi signals.

• Campsite WiFi Access Points are often too far away to connect to on your devices with only internal antennas (phones/laptops).

• Being closer to the Access points can help, but isn’t aways guaranteed.

The best fix?

An external WiFi antenna, accompanied by an internal repeater.
This set-up grabs strong WiFi signals outside and rebroadcasts them inside your vehicle, bypassing your van's metal barrier.

How this set-up works: Install an external WiFi antenna on the outside of your motorhome, which runs inside via a cable to an internal device acting as a wireless repeater.
With the source of the signal now being inside your van, the connection will be significantly stronger for any of your devices you wanted connected to the internet, whether that be a smartphone or a smart TV, because the wireless signal now isn’t being weakened by having to penetrate the Motorhome's metal exterior.

Find the right kit for you:

Temporary-mounted
Temporary-mounted WiFi repeater kits can be installed into position upon arriving at a campsite, but these must be taken down again before driving as they are not suitable to be left up when travelling.

Permanently-mounted
A permanently-mounted solution is more time-efficient than its counter-part, and can also achieve stronger performances.
A combination of the Poynting PUCK-12 WiFi antenna and the Teltonika RUTM10 router would create this high-performing permanently-mounted solution.

 

 

The PUCK-12 antenna has many key advantages that make it perfectly-suited for exactly this scenario. It’s low-profile and small size make it very easy to mount anywhere on your van, and this versatility is only enhanced by its wide array of mounting options (spigot-mounted, rail-mounted, pole-mounted, surface-mounted with adhesive foam seal, magnetic mounted). The PUCK-12 is also marine-grade (IP69k-rated), ground plane-independent, comes with its own 2-metre cabling and is just a very strong antenna in its own right, with a 7.5 dB gain. It's available in both Black and White, so you can choose which will best suit your vehicle

 

 

 

 

 

The Teltonika RUTM10 is a strong Ethernet router, which can be very simply reconfigured to scan for nearby WiFi signals and utilise that as the network source. It has 2 WiFi antenna ports, allowing you to use one for the incoming PUCK antenna and the other for an indoor aerial (included with the RUTM10) to distribute WiFi around your van.
It comes with a 18W power supply (UK 3-PIN Plug), or for other motorhome powering options; it can be powered by 12V using a cigarette-lighter adapter or a bare-wire lead. The RUTM10 can be surfaced mounted using the Teltonika surface-mounting kit for a permanent solution. View all Teltonika accessories here.
