Have you tried the Ethernet connection to see if any problems ?
If the wifi driver is Intel, check the above link.
wifi driver is dell wireless, not Intel. however i install last intel wireless 19.1.0 proset64-win 10 and the latest dell wireless and nothing change. it drives me crazy. i'm not a professional user. even though i do all the things it need for install or update wireless driver whether dell or intel. i uninstall the driver and restart the laptop, after restart windows 10 automatically install the same driver(default driver).
i'm tired of this. do you think install a fresh windows 10 could help the problem to solve?
Before a reinstall, I would google for more info on the subject. There are several threads on this subject in this forum.

thank you so much torre, thank you.
hope you be sound and well in your life.
I'm having major problems with slow internet speeds. I think i've tried everything in this thread with no success.
Since the latest windows 10 update my internet speeds have dropped majorly, I normally get 70 mbps now im getting 2-5mbps....Something is not quite right.
I've done a speed test on my phone and im getting what i should be 70mpbs, I have also tried a wirless adaptor from my Desktop pc and still getting slow speeds. I haven't tried putting an ethernet cable and running a speed test yet.
I've got a Dell L502x..seems to me that it is a setting within the computer as its doing it with a wireless adaptor aswel.
EDIT: Just ran a speed test plugged in with an ethernet cable and im getting 70mbps....
Thanks for any help
Best suggestion I can give is to try different hardware in the "gap" between your wireless modem (which clearly is delivering full speed) and your PC.
As in my case, it's pretty clear your issue is a conflict between the Win 10 update and the Wi-Fi delivery system. Since you get full speed via Ethernet and phone, it could be your wireless adapter, which likely is NOT defective, but Win 10 simply doesn't play well with it.
If you're using a range extender (as I am), try a different one, if that's practical for you. Win 10 caused a big slowdown through my Linksys range extender, but a new ASUS range extender gives me full speed.
If you're not using a range extender, try a different wireless adapter.
I was able to isolate the guilty party (if not the exact reason) because the old Linksys range extender still delivers full Wi-Fi speed to my laptop running Windows 8.1, but only 1-2 MBps to my Dell PC running Win 10. So the real issue is the Windows software.
Now I use both range extenders on my home network, with my laptop connected to the Linksys and my PC connected to the ASUS, and I'm getting full speed on both.
If you don't want to try new hardware, perhaps you could uninstall the latest Win 10 update and see if that returns you to full 70 MBps. Then at least you will have found the culprit.
