Link Safe

If the Wi-Fi in your house is flaky, you might consider a Wi-Fi range extender to push your signal that extra bit further. Or you can add Powerline adaptors that use your home’s electrical wiring to create a speedy home network with added new Wi-Fi hotspots. Improve the wireless signal in your house All of us know a house’s weak or dead Wi-Fi spots, and it’s frustrating when these are where you need a strong Wi-Fi signal most. These are most often caused by distance from the wireless router, thick stone walls, and interference. The tips, tricks and gadgets that will help improve your wireless signal.

If your house suffers from weak Wi-Fi, we first recommend that you think about upgrading your wireless router. The oldest-to-newest Wi-Fi standards are: 802.11b, 802.11g, 802.11n, and 802.11ac. If you have an older wireless ‘b’ or ‘g’ router, you should consider replacing it with a newer wireless ‘n’ or ‘ac’ device that offers longer ranges and faster connection speeds. Why not be cheeky and ask your ISP to send you an updated wireless router? If you’ve been a customer for a while, it should help you out, but watch out if it asks you to sign up for a longer term, unless you’re happy with its service.

Though newer routers may not significantly increase the range of your wireless network, you should at least get better speeds at longer distances. You wont get the maximum range and performance from the newer wireless router unless your computers, smartphone or tablets also use the same Wi-Fi standard. An old laptop is unlikely to boast ‘ac’ or ‘n’ Wi-Fi. Check the specs to see which wireless standard it is using.

Rather than buy a new laptop or desktop PC or Mac, you can buy a wireless adaptor  from just £25 $38 that plugs into a USB port. You can also add a new wireless adaptor inside a desktop PC’s case or via a PC Card slot; but good luck trying that with a Mac. What about your smartphone’s wireless? Apple’s iPhone 6 and Samsung Galaxy S4 and S5, for example, are equipped up to 802.11 ac (and backwards compatible with the older standards), while the iPhone 4 and 5 , Galaxy S, S2 and S3 are compatible up to 802.11 n.

We also recommend considering Powerline adaptors that create a fast home network using the electrical wiring in your house. This means you can take your internet around your house without losing much performance. Creating a Powerline home network is as easy as plugging in an adaptor to a power socket. Simply plug one adaptor into a socket near your router and connect it to the router using an ethernet cable (usually supplied with the adaptor). Then plug the second adaptor into a power socket in a faraway room. You can then attach this to your smart TV, Sky+ box, games console, laptop, and so on, via another ethernet cable. This means that you can do without Wi-Fi for more demanding tasks such as streaming HD TV shows or moves from catch-up TV services such as BBC iPlayer, 4oD and Sky. Powerline adaptors act as if they’re directly plugged into your router even if they’re on the other side of the house. You need at least two adaptors, and the best way to buy these are as part of a starter kit.

The best Powerline adaptors can also create a new Wi-Fi hotspot right there in the second (or third or fourth) room. These create not merely boosted signals like you get with a Wi-Fi extender but close-to-fully performing new Wi-Fi hotspots. They cost more but are more versatile and provide faster speeds than mere extenders.

A new wireless router or Powerline Adaptor set with built-in wireless are best but can cost more than a simple Wi-Fi Extender. The best Powerlines, with wireless functionality, we tested cost from around £50 $75 to $230 £150. Wi-Fi extenders such as TP-Link’s TL-WA860RE  costs less. Wi-Fi extenders catch a wireless signal and then rebroadcast it, helping to strengthen the signal from a router on a different floor of a house or on the opposite side of a building. It should be noted that they can also drag down your network’s performance. A repeater uses half its internal antennas to receive a wireless signal and the other half to transmit a new signal in effect halving the potential speed of the device’s network connection. This shouldn’t be that noticeable for light web browsing, email, and so on, but can be felt when streaming video or moving files around the network.

That’s why we prefer Powerline for the more demanding tasks. Wi-Fi extenders share the bandwidth with the router. Wi-Fi speeds are slower because it’s sharing the data between the router and the extender, whereas the Powerline simply acts as a single device (not sharing the bandwidth) and so you get better speeds. The Wi-Fi extender needs to be placed in a central location, not too far away from the main router. If you put the repeater at the far edge of your main network hoping to strengthen the signal you will reduce the speed of your connection to the rest of the network and to the internet. Remember that the extender is just boosting the signal. If it’s placed in a weak Wi-Fi spot, then it will merely push around that weak signal. Place it in an area with better Wi-Fi and the signal it pushes out will be stronger, too. The ideal location for a range extender is half way between your main router and the intended wireless devices  in an open corridor or spacious room rather than a crowded space. It should be away from interfering devices such as cordless phones, Bluetooth gadgets and microwave ovens.

We need to explain the difference between Wi-Fi bands. We’ll try to keep this as technically simple as possible, but skip if this stuff is just going to get your head spinning. Wi-Fi can work over one of two spectrum bands: 2.4 or 5GHz. The trade-offs between 2.4GHz and 5GHz have to do with interference, range, and speed. Manufacturers claim that 2.4GHz routers or extenders can reach up to 300Mb/s speeds, while 5GHz devices have a theoretical maximum  of 450Mb/s. Dual-band devices are therefore sometimes rated as 750Mb/s. Remember that these claimed speeds are theoretical maximums, and you won’t be getting anywhere near these speeds, but you can achieve perfectly acceptable wireless performance using such devices.

Each band has its limitations, though. 2.4GHz devices face a battle for the available space, and so cause interference between each other. The 2.4GHz band is also divided into overlapping channels. The more overlap, the greater the interference among networks located closely together. Switching to 5GHz alleviates the channel problem because so many more channels are available and without any overlap in the 5GHz band. But 2.4GHz does have one big advantage over 5GHz: range. The shorter wavelengths used in the 5GHz band cannot penetrate as well through seemingly solid objects like walls, ceilings, desks, and, yes, people.

The more interference, the less speed and range; the greater range you want, the less speed you can have; the greater speed you want, the more you have to mitigate interference and work closer to an access point. A dual-band (2.4- and 5GHz) Wi-Fi extender should offer the best of both worlds. The same goes for Powerline adaptors. The latest Devolo DLAN 1200+ Wi-Fi Starter Kit, for example, uses ‘ac’ and 2.4-and 5GHz bands.
