Most people will have the same router that came with their broadband package, which may be based on old wireless technology which means you may be experiencing slower speeds and poor internet signal.
...too many devices trying to connect to the same wireless network simultaneously. You can see this when you have continual buffering when you are trying to watch videos on your smart TV, smartphone/tablet or computer, especially when you have other devices surfing the web, checking e-mail or playing online games at the same time. All D-Link Wireless AC routers support dual-band wireless, operating on both the 2.4 GHz and the 5GHz wireless bands. This allows you to browse the web, chat and e-mail using the 2.4 GHz band on your smartphone and computer, while simultaneously streaming stream HD videos or playing online games on media streaming players or games console on the 5 GHz band.
...a variety of household appliances can cause wireless interference, including cordless phones, baby monitors, and microwave ovens, meaning you may experience poor network performance. The wireless network may even cut out when the microwave or cordless phone is in use.
Make sure your router is not positioned near these household appliances to help reduce interference.
The simplest solution to solving channel saturation of a broadcast frequency is to switch to another frequency. 802.11ac wireless broadcasts entirely on the 5 GHz broadcast spectrum, where there is less noise and interference from competing technologies. Moreover, there is a lot more space available in this band, allowing for up to 19 non-overlapping wireless channels compared to just three with 802.11n. Plus, those channels are wider to carry a lot more data, at 80MHz and ultimately 160MHz channels available in 802.11ac, compared to 20/40MHz with 802.11n... Giving you a seamless network at up to 4 times faster* than wireless N!
Dual-Band Wireless AC Routers have the ability to broadcast on two different frequencies: 2.4 GHz and 5 GHz, not only does this make it backwards compatible, but it also means that they are less prone to interference from other devices. You can browse the Internet on the 2.4GHz band while streaming HD movies on the 5GHz band and neither band gets overloaded. Dual band means less interference and faster speeds.
The way in which radio signals are transmitted is also changing. Out go omni-directional antennas, broadcasting every which way they can, in favour of “beamforming” technology which aims Wi-Fi signals directly at them. This provides a much stronger signal that is especially beneficial for mobile devices.
Routers with QoS traffic controls track the type of network traffic (web surfing, online gaming, Skype®, Netflix® and so on) and decide which application deserves higher priority. This improves your online experience by ensuring that high priority traffic like Netflix is prioritised over other network traffic ensuring the best video quality and user experience across all devices on the network.
