R6400 slow wifi speeds, but wired speed is ok

Question

Suddenly a few days ago, my wifi speed really nose dived. Getting wifi speeds of 4.35 mbps and similar 1 digit readings

I rebooted my modems, but it didn't help. So I rebooted the router, still didn't help, but I found a speed test on the router.

Ran it and had 300+ mbps speeds. So I found an old CAT cable and wire the laptop to the router. Still 300+ speeds.

My speeds did increase slightly for my wifi, like in the 50 mbps range.

Any ideas as to why there's such a difference?

What firmware is on the router?&nbsp;
What modem/gateway is it connected to?Did you check to see if you're connected to 2.4ghz or the 5gh?&nbsp;
did you try changing the wireless channels in case there's interference?&nbsp;
Or did you try a factory reset?&nbsp;
