2.4 GHz Network connection is so so slow!

We have a 400 Mbps Comcast service, using a WiFi 6 router, and a Net Gear 2 GB cable modem, fast equipment.

Measuring at the router, next to it, using the Infinity Speed Test, the 5.0 GHz network is blazing fast, always over 400 GHz service level.

However, the 2.4 GHz network barely can manage 100 Mbps and sometimes slower, because of it's WI-Fi coverage we need it be faster.

Why is it so slow?

Does Comcast say their service levels only are for 5.0 GHz?

FWIW, their advertised speed claims are for hardwired ethernet connections only.

Thanks for the info.  That is a good explanation of the two bands.  However, when you buy internet speeds from Comcast you would need substantially fast speeds to compensate for the 2.4 GHz band.  My plan is 400 Mbps, but I do not read where Comcast says that speed is only for the 5.0 GHz band.  I do have devices further from the router that require better coverage than 5.0 can give, but I suffer a significant loss of performance.  Sometimes it measures under 50 Mbps for the 2.4 band.

Thanks for responding.

I have the same issue… and so does my son around the corner from me.

My security cams run on 2.4 and have videos delays. 

We both have 200 Mbps service and we both have MG7700 modem-routers.

The 5.0 radio runs okay at around 200 Mbps.

But the 2.4 runs under 100 which is far under the 600 max for this modem:

Wi-Fi Speed and Performance
• Simultaneous Dual Band radios
• Up to 600 Mbps** at 2.4 GHz
• Up to 1300 Mbps** at 5 GHz

** Speeds shown are maximum wireless speeds derived from IEEE Standard 802.11 specifications. Actual speeds will vary.
