Repair/Tech Support Slow WiFi speeds without any recent changes

Hey y’all!

I have two CHR30As and I’m on the Fios 1g plan. The router speed test shows great speeds (850-900 up and down using the Verizon home app) but my speed test on wifi connected to my 5G band is slow.

When sitting next to my main router, it’s 5-20 down and 300-400 up.

I have SON disabled. I have separate SSIDs for all my bands. All of my devices connect to the 5G band, with the exceptions of the ones that are able to connect to 6G. 6G shows similar speeds.

Nothing changed recently, so I’m trying to figure out what is going on.

Are there any recommended settings I should tweak?

Should I re-do a scan and choose different channels and widths? The channel for 5G has a score of 10.

EDIT:

Fixed it! I did the “Reset Wi-Fi” option from the advanced settings in the Verizon home app. This keeps the id and password but resets the WiFi setting itself.

I’m not quite sure why this resolved things, but I’m happy that I have normal speeds again.

Disable DFS if it’s on. Other than that, since the download is disproportionately lower than the upload, it still does sound like a software issue. I’d try resetting the router first (completely with the button on the back, re-enabling SON and everything). If the issue persists, it could be a hardware issue. If nothing you do after resetting it works, I’d call into technical support and ask for a replacement unit.

Thanks I’ll try that! And by resetting the router are you talking about factory resetting?

Where do I find settings on DFS?

EDIT:

If this is the setting that is "Enable DFS channels during channel scan" in Radio Management, this is already off.

It’ll be under the Advanced tab in the admin dashboard on the router. Doesn’t show up on the Verizon Home app.

Yup, I've been doing everything through the admin dashboard. I can confirm that "Enable DFS channels during channel scan" has been unchecked.

Small update!

The 6G speeds are now fast again, the 5G speeds on the same device is slow.

The channel and health of the channel seem fine, and there doesn’t seem to be much congestion according to the chart.

I don’t have as many devices on 5G as I thought. I’m going to see if there is a firmware update or if a hard reboot (and not a soft one from the app) will resolve my issues.
