2.4ghz max speed

Hi all , hope you can help, recently had sky fibre 500 Mbps installed , I have an SR203 router , on 5ghz WiFi I get approx 480mbps but on 2.4ghz I'm only getting about 60 to 80mbps , should I be getting faster on 2.4ghz ??? Thanks

802.11n on 2.4GHz tops out at 150Mbps connection speed - as usual with wireless you'll be lucky to sustain half of that in the real world.

Depends on how many aerials the router in question and your device has and also if your using 20mhz or the 40mhz band plus environmental factors. So 11n at 2.4ghz will give normally around 150mbits to 300mbits (expect the lower) and even though 11.ac can use 2.4ghz it mostly doesn't.

AC being WiFi 5 is not much improvement on 2.4 GHz.
AC being WiFi 6 is where benefits to 2.4 GHz happen, but the router and the devices all have to be WiFi 6 capable.

And even if it connects at 300mbits you may not get that speed..

Just did a test on a 2.4gbit wireless ax connection and only getting 800mbits on a 1gbit internet connection.

That's not bad for a 2.4 GHz using 6/AX... unless you are extremely rural 2.4 is likely to have a lot of co-channel interference from all the other stuff in that band.

Obviously the typo in my original post doesn't help, second line should start AX (not AC).

i had an AX connection at 2.4gbit on 5ghz

Yes, AX with 5 or 6 GHz is designed to go faster. This is why the industry has moved away from using the 802.11 letters and use the version number of WiFi 6 or 6e.

Version 7 is becoming more common, but many UK vendors (including Ubiquiti) are only doing dual freq, forgetting that 7, like 6e can use the 6 GHz band.

They haven't forgotten it, and they aren't only doing dual frequency: it's available in their higher-end products, U7 Pro and above.

They've left out 6GHz from the U7 Lite to save cost and/or to persuade people to buy the more expensive models.

Many other vendors (including ASUS) appear to be leaving out 6 GHz in the UK/European models, but including it in the US/Asia Pacific. I can only conclude this is because Ofcom and the EU regulators have only allocated 50% of the 6 GHz capacity the other regions have.
