Do I need Wi-Fi 7 if my internet plan is 500 Mbps?

No. A Wi-Fi 6 router on an 80 MHz channel already delivers about 1 Gbps real throughput at close range, well above a 500 Mbps plan. Wi-Fi 7 pays off only with gigabit-plus plans and Wi-Fi 7 clients.

Is 6 GHz worth it in an apartment building?

Often yes, because 6 GHz (5.925–7.125 GHz) is much less crowded than 2.4 and 5 GHz. The trade-off is shorter range, so you may need an extra node for far rooms.

Should I use 40 MHz on 2.4 GHz?

Usually not. In dense areas, 40 MHz on 2.4 GHz overlaps more neighbors and increases retries. Stay at 20 MHz unless you live in a detached house with no nearby networks.

Why is my speed test fast but pages still load slowly?

That pattern points to DNS, not Wi-Fi. Change the router's DNS servers to a fast public resolver, clear the client cache, and retest browsing rather than throughput.

Home Wi-Fi, step by step

ReynaNets — Home Wi-Fi Networks | reynanets.com

A fast, reliable home network comes from three decisions: which Wi-Fi standard your router supports, where the hardware sits, and which channel and band each device uses. This guide walks from unboxing to speed test, then diagnoses the five failures that break most home networks.

Quick decisions

Scroll the strip sideways — 6 cards.

Standard

Wi-Fi 6 is the safe default

OFDMA, MU-MIMO, 160 MHz channels and Target Wake Time make it the best value for most homes in 2024–2026.

Band

6 GHz is the real upgrade

Wi-Fi 6E and Wi-Fi 7 add 5.925–7.125 GHz, giving clean spectrum when 2.4 and 5 GHz are crowded.

Placement

Center, high, open air

1.5 m up, away from metal and concrete, beats any antenna upgrade you can buy.

Mesh

Wire the backhaul

One wired mesh node is worth more than two wireless hops, which halve throughput each time.

Channels

20 MHz on 2.4 GHz

In dense neighborhoods, narrow channels reduce retries and stabilize the whole cell.

Diagnosis

Fast test, slow browsing

When throughput is fine but pages crawl, suspect DNS before the Wi-Fi standard.

Which Wi-Fi standard should your router support?

Buy Wi-Fi 6 or Wi-Fi 7 if you can; Wi-Fi 5 is the floor for a modern home, and Wi-Fi 4 is only acceptable for low-demand devices.

The four current generations differ mainly in three things: which bands they use, how wide a channel they can carry, and how efficiently they share that channel between clients. Wi-Fi 4 (802.11n) arrived in 2009 and works on 2.4 GHz and 5 GHz. Wi-Fi 5 (802.11ac) arrived in 2014 and works only in the 5 GHz band, with 80 MHz channels and optional 160 MHz. Wi-Fi 6 (802.11ax) arrived in 2018 and added OFDMA, multi-user MIMO, 160 MHz channels and Target Wake Time for battery-powered devices. Wi-Fi 7 (802.11be) arrived in 2024 and adds 320 MHz channels in the 6 GHz band plus 4K QAM.

For most homes the practical answer is Wi-Fi 6 as a minimum, because OFDMA and multi-user MIMO keep many devices responsive at once, and Target Wake Time extends the battery life of phones, sensors and doorbells. Wi-Fi 6E and Wi-Fi 7 add the 6 GHz band, expanding usable spectrum from 5.925 GHz to 7.125 GHz — that clean band is the single biggest reason to upgrade if your street is crowded with 2.4 and 5 GHz networks.

Wi-Fi 7's 320 MHz channels and 4K QAM only pay off if both the router and the client support them. A Wi-Fi 6 client on an 80 MHz channel still tops out near 1 Gbps real throughput at close range (1201 Mbps PHY for a 2x2 client), which is more than most home internet plans deliver. Match the router to your clients, not to the marketing number.

2.4 GHz: longest range, most interference, use for IoT and legacy gear.
5 GHz: best balance of speed and range for phones, laptops and TVs.
6 GHz: cleanest spectrum, shortest range, needs Wi-Fi 6E or Wi-Fi 7 clients.
Channel width: 20/40 MHz on 2.4 GHz, 80/160 MHz on 5 GHz, up to 320 MHz on 6 GHz.
