What Is WiFi 6 (and WiFi 6E)?

by Priya Nakamura Updated Apr 12, 2026

WiFi 6 (802.11ax) is the latest mainstream WiFi standard, offering faster speeds, better performance in crowded environments, and improved battery life for connected devices. WiFi 6E extends this to the 6GHz band for even more capacity.

WiFi 6 Benefits

WiFi 6 provides up to 9.6 Gbps theoretical max speed (vs 3.5 Gbps for WiFi 5), handles more devices simultaneously, and includes Target Wake Time (TWT) to improve device battery life. It's especially beneficial in homes with many connected devices.

WiFi 6E

WiFi 6E adds the 6GHz frequency band, providing even more channels and less interference. It requires both a WiFi 6E router and compatible devices.

Pro Tip: Every device on the internet has an IP address, but thanks to NAT, hundreds of devices can share a single public IP.

Key Takeaways

Private IPs (192.168.x.x, 10.x.x.x) are used inside your home network
DNS translates domain names to IP addresses
DHCP automatically assigns IPs so you don't have to
Your default gateway is your router's IP address

Frequently Asked Questions

Do I need a WiFi 6 router?

If you have many devices or want the best performance, yes. But WiFi 5 routers are still perfectly fine for basic internet use.

Are WiFi 6 routers backwards compatible?

Yes. WiFi 6 routers work with all older WiFi devices (WiFi 5, WiFi 4, etc.). Those devices won't get WiFi 6 speeds but will work normally.
