Recently all my wifi devices (tablet, laptop, phones) are connecting at much lower speeds (90 Mbps) compared to my wired PC (550 Mbps.) Is there anything I can do to get my wireless speeds back up?
None of my habits have changed- my router is in the same location, I have the same wireless devices, and I'm using them at the same distance from the router as before (my house is small so no device is ever extremely far from the router.)

How are you testing? using an app/browser?
Have you tried changing testing servers? I've found many times that it wasn't a speed issue but the testing server picking the wrong server to test on.
Have you tried changing wireless channels? maybe there's interference?
How about wireless channels? are you testing on 2.4ghz or 5ghz? 5ghz is significantly faster than 2.4ghz.

I've tested my speed at www.speedtest.net and with Ookla's speed test app. I haven't changed wireless channels; I'm not sure how to do that. All my devices are on 5ghz. I just assumed it was a speed issue since we're experiencing weaker connections like unclear facetime calls and devices getting forced to use cellular data due to "no network connection" error. What do you think I should do?

Try a different testing site.
try dslreports.org
or switching servers on the speedtest app. It defaults to the one with lowest ping but that isn't always the best.
Also, you can download a wireless channel scanner for free usually. Try downloading on and doing a wireless channel scan.
Maybe there's interference and it needs to be switched.
The channel settings are on the same page as the SSID password.
Usually 2.4ghz is set on auto. the 5ghz you pick the channel.
