Question Weird WiFi adapter issue

[MtnMan]

Wife was grumbling about pages not loading on her laptop. So I close the many many tabs she has default to open, and just try Google. sloooooow, OK, speed test next, 0.12 Mbps (we have 200/10 service). Pull out phone, run speedtest, get 215/15... so not internet. Reboot router, restart laptop, rollback to restore point, reinstall drivers for WiFi card (Qualcomm QCA9377) after thumbdrive transfer from my laptop. Nothing changes.

So I'm poking around in device manager, and under the advanced tab there are options for which bands to use (a/b/g/n/ac) is the default. I choose (g/n) and restart. Speeds are now 50 to 70 Mbps. Set it to a/g/n/ac, restart and now I get 215/15 on speedtest. What the heck?

Happens. Oh well. Happy wife, happy life.

In years past I recall older versions of windows could have a problem with network adapters (drivers) coming out of sleep mode. Maybe that's not it but I'd check on a newer driver, based on the chipset manufacturer if the laptop OEM didn't update theirs.

Windows 10, latest driver from Dell. Dell diagnostics run clean.

Always the #1 rule, especially under the "stay home" orders at the moment.

Okay, that is pretty close to the exact opposite of what I meant which was specifically, to disregard whether you have the latest from the OEM because they may not have updated to the latest that exists.

There may not be a newer driver, but if there is, odds are that something needed fixed still.

Have you tried to find anything on the Qualcomm website?

It does look like Qualcomm doesn't want to support end users, but that wouldn't stop me from checking what driver version I have and looking elsewhere for a newer version. Here's 12.0.0.938, not sure if there's newer out there or not:
