OS
Windows 11
I have a very up to date Vostro computer running latest version of Windows 11. I have Verizon FIOS 1 gig service. I usually get speeds of about 700/00 on wi-fi. Last I rebooted my computer and as soon as I opened a browser I saw that speeds were off. I am down to .45-1.5 mbps down and about 200 up. It crawls and is almost unusable. Router is giving same signal and other devices are getting the same high speeds as always. I rebooted the router, updated all of my drivers using the Dell update feature. Updated the BIOS and OS. All to no avail. Verizon tested all equipment and it working fine. Dell tested everything as well and basic support found not issues. I tried to roll back the driver on the wi-fi card to a date before the problem started but still no better. Any suggestions? TY

Have you introduced anything new in your nearby environment that is interfering with the wireless signal of this particular device? Large mirrors, metal, tile, 2.4 ghz devices, bluetooth, microwave ovens, cordless phones. ,
Things to try:
Connect wirelessly after each step and see if speed has improved.

This issue could be either hardware or software related. From a software standpoint, here are things to try.


1. Powercycle your router. Restart laptop. If it doesn't help, test using the other band of you router's wifi to see if speed changes.

2. Run network troubleshooter. Settings>System>troubleshoot>other troubleshooters>Network & Internet>-RUN

3. Reset network adapters Reset Network Adapters in Windows 11 Tutorial

4. Attached is @FreeBooter .bat file which resets network components. RIGHT click on the .bat file and select run as administrator.

5. Check for file system corruption. Open a command prompt as administrator and type
sfc /scannow
After system file checker completes, make note of whether it found and corrected any problems. If found and corrected, restart
If it found problems it could not correct, in command window type

dism /online /cleanup-image /restorehealth
Restart

6. Change power settings for wireless adapter in Power Options. Control Panel-power options-Balanced should be checked
Next to balanced, click change plan settings
Click Change Advanced Power Settings
Expand Wireless Adapter Settings
Expand Power Saving Mode
Under Setting change it to Maximum Performance

7. Open Control Panel-device manager
Expand Network Adapters
Right click on your wireless adapter and select properties
In Power Management tab- Uncheck 'allow the computer to turn off this device to save power'
Note: Changing these power settings uses more power, thereby affecting your battery if you used on a laptop..

8. Repair Install Windows 11 Repair Install Windows 11 with an In-place Upgrade Tutorial

If none of that works test with another wireless adapter. USB wireless adapters are cheap where I live (about $10). I keep one around to test with in just such cases. Hope one of these suggestions help

What does 00 mean?

What windows version please? "running latest version of Windows 11" is meaningless. The latest stable version is 23H2 Build 22631.3296 on my PC but you may be running Insider, Beta versions?

Also have you introduced anything new that can interfere with the Wi-Fi signal? See: -
Typo, I am sorry, should read 700/700, meaning up and down. My Windows version is 23H2. Excuse my ignorance please. And, do not believe that I introduced anything new. Dell ran tests and said that all Hardware as OK and that it's a software issue. TY everyone for your suggestions. Will read more carefully and execute later

This is a weird one. I hope that @glasskuter advice can help you. Remember our advice (posts 2 and 3) to check for things that you may have introduced which may be blocking the Wi-Fi signals.

Good luck. Hope you get it fixed.

I tried something else too. The only other network that I have access to is a Verizon cell phone on 4G. I did get better results. When FIOS was giving me downloads of 0.62 my hot spot created from my cell was giving me almost 4.0. I have rebooted the router multiple times, disconnected and reconnected to no avail. And, just to reiterate, trouble started after a reboot.

I am trying each one slowly. I did not introduce anything new. It just happened after a reboot.

That's extremely bad! Looks like ISP tech-support time.

My suggestion......if possible connect an ethernet cable from your PC to the router and see how the speeds are. That will help eliminate the wireless connection as the possible issue. If the ethernet connection is off then you're spinning your wheels troubleshooting wireless speeds.

Click on the WiFi icon in the task area, Then the > next to your WiFi connection, then click on the i with a circle around it. Are you connected to 5 ghz band or 2.4 ghz band? What does it say there for link speed?

SO, latest is that I paid for Dell paid support. They spent 2 hours trying to fix and couldn't. Now they want to reinstall Windows but I feel that that is radical!

You did not answer my question whether this happened before or after the last Windows update.

If it's not related then #8 of @glasskuter 's advice could save you the trouble of a full re-install.
