realtek rtl8723de 802.11b/g/n pcie adapter not working

[PK1245]

Hi, Im getting connected to Wifi only if i am within 2 feet of the router and that too only 1 bar of connection is available with a speed of 1-2 Mbps where as my wifi is more than 100Mbps on other devices in longer range. Tried all the steps of reset and reinstall, does not seem to be working. Please help.

Hi:

It is possible that the antenna wire has become disconnected from the Wi-Fi card, or the Wi-Fi card is going bad.

The only suggestion I can offer would be to open up the PC and check the antenna connection or replace the existing Wi-Fi card with this model:

Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.

You can find this model on eBay, or Ali Express. 

I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.

Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure:

There is also this service teardown video.  The 15s-ey0000 model series and your model use the same service manual.
