Realtek Wi-Fi Adapter Download

HP Recommended
HP Pavilion 15t-n200 CTO Notebook PC (ENERGY STAR)
Microsoft Windows 10 (64-bit)

I have the HP laptop product HP Pavilion 15t-n200 CTO Notebook PC (ENERGY STAR)

 

About a month ago or maybe even longer, the wi-fi started going out at random times. It has gotten progressively worse overtime. As of now, my wi-fi goes out randomly throughout the day, but primarily later in the day/at night. And it goes completely out, I know because not only does the laptop not detect my home wi-fi, it doesn't detect any nearby networks.

 

I figured out that I can run the HP Network Check when it goes out and it restores the wi-fi after resetting all of the following:

Realtek RTL8188EE 802.11 bgn  Wi-Fi Adapter

Realtek PCIe FE Family Controller

My Wireless Network Adapter

 

I have already tried nearly all of the troubleshooting steps found on this support website. It really appears to be something with these Realtek drivers the computer is using. I tried looking for a more recent driver directly on Realtek's website and it appears that the driver I have on my computer is not the most current one. For the driver I have right now, I have a driver date of 7/21/2015 and version 2023.15.701.2015

 

In case you're wondering, yes I have tried uninstalling and reinstalling the drivers from the device manager and if I remember correctly I even tried doing it from the HP website too. Anyways, on Realtek's website I found this driver download and the driver software is dated from June of 2017. It appears to be an updated version to the driver I currently have but I'm not sure.

 

Can someone confirm that this would be the correct driver to download? This is the link where I found it:

 

https://www.realtek.com/en/component/zoo/category/rtl8188ee-software

 

Also, what am I supposed to do after downloading it? Because I already tried going through the download and all I got was a zip file of a bunch of different stuff.

So the Realtek RTL8188EE 802.11 bgn Wi-Fi Adapter seems to have been updated on my PC now. I used the link you provided and from the device manager, the driver now shows a driver date of 5/26/2019 and version 2024.0.4.208.

 

But now what about this Realtek PCIe FE Family Controller? What even is that? I looked it up online and from what I gather its something that requires use of an ethernet cord, is that right? I don't use an ethernet cord. At one point, I disabled that driver and my wi-fi was functioning just fine without it, so do I even need it? Anyways, the PCIe FE Family Controller might also be outdated. It's showing a driver date of 8/15/2013 and version 8.20.815.2013 is there a more updated version that I should have?

You are correct.

 

The  Realtek PCIe FE Family Controller is the 10/100 MBPS ethernet (wired) controller.

 

I recommend you use the latest driver directly from Realtek for that one.

 

Download, unzip and run the setup application from the W10 driver file from the link below...

Thanks, I have both drivers updated now. The PCIe FE Family Controller now shows a driver date of 9/28/2020 and version 10.45.928.2020 I will now give it some time to ensure that the wi-fi functionality on my computer is stable and reliable.

So unfortunately the wi-fi just went out again on my PC. There must be something really wrong. Again I used the HP Network Check and it did the exact same thing as before.

 

When I go into the device manager>network adapters>Realtek RTL8188EE 802.11 bgn Wi-Fi Adapter>properties>events>view all events then select administrative events under custom views, I have a huge list of warning and error messages (almost 14,000) they go back to 9/13/2020. Anytime the wi-fi goes out, I've been checking those events and there's always some warning and/or error message(s) coming up. I also notice on the events tab (on the properties window) it shows the same date with description "device install requested" followed by a bunch of other stuff. Could all of this mean anything? Should I attempt to do a system restore on my PC to a date before 9/13/2020?

 

To give an idea of the things I've already tried, I have:

Configured power settings on the drivers so that the computer does not turn them off to save power

Reset the Wi-Fi router in my household

Performed some kind of resets using commands on the command window

Performed a hardware reset on my PC (shut down PC, remove battery, hold power button down for 15 sec & reset router)

Did a scan using some diagnostic tool on the HP website here to see if it could be a hardware issue but it didn't detect any problems.

 

Any other things I could try doing?

I was just trying to manually change network settings (step 3 on this page https://support.hp.com/in-en/document/c06282875)

 

When I bring up TCP Global Parameters I get a pretty different list than what the sample solution shows. Also, there's no instruction on how to change these settings, should I change something and if so how? Here's a look at the settings I have:

 

Receive-Side Scaling State: Enabled

Receive Window Auto-Tuning Level: Disabled

Add-On Congestion Control Provider: Default

ECN Capability: Disabled

RFC 1323 Timestamps: Disabled

Initial RTO: 1000

Receive Segment Coalescing State: Enabled

Non Sack Rtt Resiliency: Disabled

Max SYN Retransmissions: 4

Fast Open: Enabled

Fast Open Fallback: Enabled

Hystart: Enabled

Proportional Rate Reduction: Enabled

Pacing Profile: Off
