5Ghz network slower than 2.4Ghz

[cdmain12]

Hi,
I have a NBN 50 HFC connection and am using a supplied Archer 1600 modem.

I have noticed than my 5GHz download speed is around 35Mbps, while my 2.4Ghz is 45Mbps. Why would my 5Ghz be slower than 2.4Ghz?

I am close to the router so no obstacles are in the way and I am using my pixel 2 and speed test for the measurements. My phone, router and android tv box are the only 5Ghz devices in the house. I turned off my Android TV unit and tested same results.

I have rebooted the router and have same results.

From my research 5Ghz should be faster than 2.4 Ghz if the signal is not attenuated too much, so in my case I cannot see why it is slower. Any ideas?

Hi @cdmain12

Welcome to the Community!

Even though you are using the 5GHz network of your modem/router, it is possible that signal interference is causing the slow speed issue.

Hi BasilDV,

Glad to be part of the community.
I have tried different channels. No change.

The router channel was previous set to auto. Any other thoughts?

Hi @cdmain12

May we know the channels that you've already used? Have you tried turning off and on the modem/router after changing the channel?

Yes I have rebooted as well.
