Realtek RTL8723DE 802.11b/g/n PCIe Adapter Slow! Only 15mbps!

[Notsobad22]

Hello, this is going to be a long post with several sources.

In summary, my computer has only been running at 20mbps but it went down to 10mbps and I simply cannot work like this.

Important Note: Command prompt claims "Media DIsconnected" but I have a little internet connection (subpar, but some connection).

I've tried everything from

This official HP post (HERE )

This official Microsoft post (HERE)

And several other Forums (HERE1)* (HERE2)* (HERE3)

Easier things I've done:

• My disk has always run very high (could be unrelated to the issue)
• I have reset the modem for a power cycle 12 times now
• I have run the troubleshooter and it acknowledges there may be an issue but is unsure what it is.
• I have completed several network resets
• I have updated/reinstalled my drivers
• I have turned off sharing with other computers
• I have verified my network adapter is enabled
• I have factory reset 3 times

More Complex things I've done (underlined if done in Command Prompt)((Remember to read the second forum link on how to allow permissions to everyone for these steps))

• I reset the WINSOCK and IP stack*
• I reset the IP stacks separately IPv4 IPv6*
• I reset the TCP/IP*
• I believe my IP is a DHCP connection

This is too detailed for the virtual assistant, I really need to get back to work. Please if you have any other solutions let me know I don't really have the money to replace the driver (but I plan to because I want a 5Gz connection eventually.)

Thank You

Hi@Notsobad22, Welcome to the HP Support Community!

Unfortunately, I am not up to date on what notebook PC's HP has on the market today.

My newest HP notebook is 5 years old.

What you want to look up the next time you are shopping for a notebook regarding its wireless specs, is to find one that has an AC wireless card and a gigabit ethernet adapter.

Here is a rule of thumb...anytime you see a wireless N adapter with a suffix that ends in 1x1 b/g/n such as what your notebook has, that means it is a single band, 2.4 GHz wifi adapter only.

Dual-band wireless N adapters have suffixes that end in a/b/g/n or a/g/n.

Dual-band wireless N adapters normally connect at 144 MBPS on the 2.4 GHz band, and 300 MBPS on the 5.0 GHz band.

Dual-band AC cards...

1 x 1's connect at a max of 433 MBPS, and 2 x 2's connect at a max of 866 MBPS.

So, for example...I just randomly selected a model from your series below...

https://support.hp.com/us-en/product/hp-15-bs100-laptop-pc/16851388/model/19460259/document/c0587700...

Next to the wireless connectivity specification, you see this...Intel® 802.11a/b/g/n/ac (1x1) Wi-Fi® and Bluetooth® 4.2 Combo

That will tell you based on what I posted above that it has a 1 x 1 wireless AC adapter, and you can expect to have a maximum connection speed of 433 MBPS in the 5.0 GHz band if you have a wireless AC router.

I happen to know the wifi model referenced is the Intel 3168 AC wifi adapter, and here is the link to the specs for that model wifi card.

Hope this helps! Keep me posted.
