That is also called BE65, and I'm running the same f/w and my ISP speed is 1Gbps as well.

I've got an Intel BE200 M.2 adapter.

If I run the speed test in the Deco app on my phone, this is what I get:

Yet I can't reach that spped on wireless:

Not even close.

I am using the MLO band, and the 6Ghz is about the same.

The older f/w I was getting about 800Mpbs+, approaching 920Mbps.

Not sure why it is this way? The PC is litterally 10Ft away from the router.

Here's a screenshot of my history via the app running on my phone, as well as a speed test on my AT&T Gateway:

I'm wondering if you had a power drop?

I have an UPS on all PC's, Router and Modem. As long as the power drop isn't for afew hours, we are OK (also is the ISP didn't drop cable signal). However, our printer is no a UPS... and it seems that when power comes back, it occasionally gets a new IP address (wireless connect for the printer) and our PC's can't print, new to 'search' on the PC's for a printer (HP printer) to be able to print as they find the new address.

Modem's tend to remember devices connected to them. If they have a 'bad' connection, speeds will be slower.

I suggest you turn off the modem, router, and all devices. Power on in sequence, the modem, router, and devices, making sure the modem is Fully up before powering the router back on, and after the router is up, the devices and test. Hopefully this will 'fix' it?
