Wi-Fi 6, 6E and Wi-Fi 7: What the New Standards Give You, Whether to Replace Your Router and Why Speed Didn't Improve After Buying One

Every few years a new Wi-Fi standard arrives, and router makers promise speeds of several gigabits. Many people buy a new router hoping the internet will "fly" — and find that nothing much has changed. It isn't a con: the new standards really are better, but the gain depends on your plan, your devices, your flat and your neighbours. Let's look at what Wi-Fi 6, 6E and Wi-Fi 7 really give you, who should replace their router and why it sometimes doesn't help.

The standards in brief

• Wi-Fi 4 (802.11n) — an old standard, mostly 2.4 GHz. Routers using it are still found from providers and in older flats.
• Wi-Fi 5 (802.11ac) — the 5 GHz band, with real-world speeds in the hundreds of megabits. Enough for many homes.
• Wi-Fi 6 (802.11ax) — the main improvement isn't peak speed but efficiency: the network copes better with dozens of devices at once, latency is lower and phone batteries last longer.
• Wi-Fi 6E — the same Wi-Fi 6, but with the extra 6 GHz band: plenty of free, wide channels without interference from the neighbours.
• Wi-Fi 7 (802.11be) — even wider channels, simultaneous operation across several bands (MLO) for speed and stability, and lower latency. It pays off with very fast plans and modern devices.

What limits real-world speed

• Your plan. If the provider gives you 100 Mbit/s, no router will deliver more. Wi-Fi 6 and 7 come into their own on plans of 500 Mbit/s and up.
• Your devices. A phone or laptop with Wi-Fi 5 will run at Wi-Fi 5 even with a Wi-Fi 7 router. Only new devices get the new features.
• Walls and distance. The 5 and especially 6 GHz bands pass through walls less well. In a far room a fast standard may run slower than old 2.4 GHz next to the router.
• Router ports and cabling. If the provider's cable or fibre terminal is on a gigabit port and your plan is faster than a gigabit, you need 2.5 Gbit/s ports.
• The neighbours. In Tbilisi's high-rises the 2.4 GHz airwaves are crammed with dozens of networks. That's where Wi-Fi 6's efficiency and 6 GHz's clean air give the biggest gain.

When a new router really will help

• An old Wi-Fi 4 router from the provider, and lots of modern devices at home.
• A fast plan (500 Mbit/s and up), but Wi-Fi delivers a fraction of it.
• Many devices at once — phones, laptops, TVs, cameras, smart home gear — and the network "chokes" in the evening.
• Online gaming, video calls and streaming suffer from latency spikes.
• The router runs hot, freezes and needs restarting.

When it won't help

• A slow plan — change that first.
• The problem is coverage in a large flat or house — you need a mesh system or wired access points, not one powerful router.
• All your devices are old — the gain will be minimal.
• The problem is on the provider's side — line dropouts or overloaded equipment.

What to look for when choosing

The number on the box (such as "AX3000" or "BE9300") is the sum of the theoretical speeds of all bands; the real speed on one device is always far lower. What matters more is support for the bands you need, 2.5 Gbit/s ports for fast plans, the ability to join a mesh, regular firmware updates and WPA3 support. For an ordinary flat with a plan of up to 500 Mbit/s, a good Wi-Fi 6 router is enough for years to come; Wi-Fi 7 makes sense with gigabit plans and new devices.

Setup matters too

Even the best router works badly if it sits in a cupboard, uses a congested channel or runs outdated firmware. Placement in the middle of the flat, choosing free channels, separate or combined network names for the bands, and switching off outdated compatibility modes all have a big effect on the result.

What our technician does

1. Measures real speed by cable and over Wi-Fi in different rooms.
2. Identifies what's limiting the speed: the plan, the router, the devices, coverage or interference.
3. Selects a router or mesh system to suit your flat, plan and devices.
4. Installs and sets up the router: channels, bands, security and firmware.
5. Checks the result with measurements and adds access points if needed.

A real example

A family in Ortachala signed up for a 500 Mbit/s fibre plan, but their phones showed 60–80 over Wi-Fi, and video on the TV froze in the evenings. Our technician found they were using the provider's old Wi-Fi 4 router, running only on the congested 2.4 GHz band. We installed a Wi-Fi 6 router, placed it in the middle of the flat, set up the 5 GHz band on a free channel and connected the TV by cable. Phone speeds rose to 350–450 Mbit/s, and the evening freezes stopped.

Provider-supplied routers deserve a special mention. They're often inexpensive models designed for minimal use, and they don't always get firmware updates. Many providers let you use your own router: the fibre terminal is switched to bridge mode and your router takes over the whole home network. This needs doing carefully so you don't lose internet, TV or phone service if they share the same line. Before buying, check with your provider which settings are needed to connect.
