For example, if a router has a 2.4GHz radio that supports speeds up to 400Mbits/sec, plus two 5GHz radios rated at up to 867Mbits/sec, the manufacturer may tot these up to advertise a total speed of 2,134Mbits/sec. They also have a misleading habit of adding up the speeds of different radios to come up with a total data rate. Router manufacturers advertise some very fast transfer speeds, but these are theoretical maximums: you’ll never get close to them in real life. If that sounds good, check out our guide to the best mesh Wi-Fi systems on the market. A mesh kit will be more expensive than the average router, but if you’re struggling to get a decent connection in the far reaches of your home, it could be the perfect answer. What’s the difference between a wireless router and a mesh system?Ī mesh system does the same basic job as a router, but alongside the main unit it comes with additional “satellites”, which you place around your home to help distribute the wireless signal more widely. This applies especially to 802.11ac – so a tri-band router contains two separate 5GHz radios, allowing twice as many devices to communicate simultaneously at full speed.Īs we’ve mentioned, though, 802.11ax copes much more elegantly with simultaneous connections, so tri-band technology is generally unnecessary with the new standard. So far so good, but when multiple clients try to connect to the same radio, contention and interference can slow things down. The 5GHz band is fast, but some older devices don’t support it the 2.4GHz band is slower, but it has a longer range so it can be good for big old houses with thick walls. What’s the difference between dual-band and tri-band?Īll modern routers can transmit and receive on two radio bands at once. And don’t worry about your older devices: they’ll still be able to connect, as all 802.11ax routers are backward-compatible with 802.11ac. And since it’s designed for the connected age, it gets bogged down much less than 802.11ac when lots of devices want to connect at once.Īlthough 802.11ax routers may be more expensive than older models, it’s now very widely supported, and we’d suggest it’s the right choice for most people. It also has better penetration, so that all corners of your home or office can get a decent signal. Wi-Fi 6 – or 802.11ax, to give it its proper name – is the current wireless standard that gives you a faster connection than older Wi-Fi 5 networks.

However, in this configuration your new network will technically be a subnet of the old one: this could cause issues with communications between devices, or if you want to set up port forwarding. If it doesn’t, you can connect a new router to a spare Ethernet port on the old one, and use this as your main home network. If you don’t have a standalone modem, check whether your ISP-supplied router offers a “modem mode” that will let it do the same job. ![]() Most however just offer a WAN port, and expect you to provide your own modem. ![]() A few models have built-in ADSL2+ or VDSL2 modems, allowing them to connect directly to DSL or fibre broadband services. How to buy the best wireless router for youīefore investing in a new router, think about how it will work with your internet connection.
