Very Slow WIFI Speeds on an HP 14-cf1062st Laptop with Realtek WIFI/Bluetooth Card

[einstem]

I purchased an HP 14-cf1062st Laptop (Model # 6HF88UA#ABA) from staples earlier this year and the speed when I am on WIFI is VERY slow on my laptop.  We have 400/20 Internet service in our house but my laptop using a "speedtest" is only getting to about 35 to 40 Upload and about 10 download.

I'm not sure if there is an issue with the WIFI card, or if perhaps it is a DRIVER issue.

I think it used to run "faster", but now seems much slower all the time.

I also noticed that a bunch of "HP Updates" were recently applied, including some for the RealTek Adapter, which I believe it has for its WIFI and Bluetooth, so not sure if maybe a recent update had a bad impact on the WIFI, or if that is just coincidence.

The "specs" that I have from Staples indicate that it has a "Realtek RTL8723DE 802.11b/g/n and Bluetooth 4.2 Combo Card".

But what is also a bit strange is that when I looked in "Device Manager", it shows the Wireless Card as a "RTL8723CE", which is an earlier version, but I don't know if that is just because the driver may perhaps be the same?

Anyone know of any issues with these laptops and the WIFI card and anything I can do to test out and see what I can do to improve my WIFI speed, since 30/10 is absurdly slow.

When I plug my laptop into the network directly with an Ethernet cable, I get about 390/20 speed, so I know the issue is specific to the wireless card.

Perhaps I can reload the default driver again and see what that does, but I'm not sure which one is the "right driver" for my laptop.

Thanks

Speedtest will give you SAME (or very close) for all machines on your network, no matter which one. Because speedtest uses speed from your modem/router to the server(s), NOT from your router to your machine. Your machine actually uses WLAN RT AC 1x1 +BT M.2 223 part # L17365-005.

I don't know why its specs shows

      Realtek RTL8723DE 802.11b/g/n (1x1) and Bluetooth® 4.2 combo

That may be true that why it is slow. Note: nothing to do wit speed test. If Speed test ONLY give you 40/10 then plaese ask your provider yo fix it.
