Wi-Fi 6, Wi-Fi 7 and Mesh: How to Fix Slow Wi-Fi at Home

Most slow Wi-Fi is not caused by your internet plan. It is caused by where the router is, how many devices share it and what is in the way. Newer Wi-Fi versions help, but the basics matter more.

The Wi-Fi versions in plain words

  • Wi-Fi 5 (802.11ac): the older standard still found in many routers. Fine for a few devices.
  • Wi-Fi 6 (802.11ax): handles many devices at once better, which suits homes with phones, TVs, cameras and smart devices all online together.
  • Wi-Fi 6E: Wi-Fi 6 with an extra 6 GHz band that is less crowded. Your devices and your country’s rules must both support it, so check before paying extra.
  • Wi-Fi 7 (802.11be): the newest standard, with wider channels and the ability to use several bands together. Useful mainly if your devices also support it.

A new router only speeds up the devices that support the new standard. Older phones and laptops keep working but do not get the full benefit.

2.4 GHz versus 5 GHz

The 2.4 GHz band reaches further and passes through walls better, but it is slower and more crowded. The 5 GHz band is faster over shorter distances. Many problems come from a device sitting far from the router on 5 GHz or in a crowded part of 2.4 GHz.

Fixes that work before you buy anything

  • Put the router high and central, in the open, not inside a cupboard or behind the TV.
  • Keep it away from thick walls, metal shelves, mirrors and microwave ovens.
  • Restart the router now and then, and keep its firmware updated.
  • Use a wired (Ethernet) connection for the devices that stay in one place, such as a desktop, a smart TV or a games console.
  • Change the Wi-Fi password if unknown devices are connected.

When a mesh system helps

Mesh systems use a main router plus extra units placed around the home so the signal covers every room under one network name. They suit larger or multi-floor homes and houses with thick walls. The units work best when they are connected by a network cable (wired backhaul) or are placed halfway between the router and the weak area, not in the weak area itself.

Cabling is still the best upgrade

For new builds and renovations, running network cable to the rooms where you need it (and to a ceiling spot for an access point) is cheap compared with fixing it later, and it makes any Wi-Fi system work better.

We plan and install home and office networks, Wi-Fi coverage and cabling in Guntur and Vijayawada. Starting prices are on the networking page, and we confirm the scope in writing after checking your space.
