WiFi ping peridocally drops - Realtek RTL8821CE 802.11ac PCIe Adapter

[ReDPanDaMan]

Hi All,

My laptop can connect and use the internet, however the ping frequently drops on a very orded basis, specifically every 9th packet during a ping test in the command prompt using the command "ping google.com -n 20". See below:

My laptop is a HP Pavilion - 14-ce0505sa running the network driver Realtek RTL8821CE 802.11ac PCIe Adapter on windows 10. I have had these issues for awhile now but seemed to have got worse.

I have isolated this issue to my laptop because of the following:

- Other devices work fine videocalling/gaming such as phone, tablets when connected to same network in the same room.

- Have tested on another laptop in same room to same WiFi with same network driver and their ping flucuated between 20 and 30ms, very normal. However mine is around 20-30ms  and then it jumps to 2000-3000ms or even times out on the 9th packet, making videocalling impossible.

The picture below is their ping result on another device, same connection and same room, showing that something is clearly not right with my device as theires never goes above 30ms:

I have tried these following solutions:

These solutions do not work for me though unfortunately. I have even bought WiFi dongle and used this for my internet, but I have the exact same issue on this device, no matter if I use the built in WiFi or the external WiFi Dongle. I have removed and reinstalled network drivers as well. Does anyone else have any suggestions on what to do to solve this and what is causing this? I have ran out of ideas.

Thanks,

Hi:

The only suggestion I can offer if you have not done so already would be to update the Realtek wifi driver to the latest version and restart the PC.

Hey,

I did not have this version installed, I have installed it now. It appeared to work for an hour or two after installing but now it seems to have reverted back, giving me massive ping spikes again every 8-10 packets...

All fixes I have tried appear to work at first but then don't after a few hours for some reason! That is why i held off on responding straight away.

Sorry that the updated driver didn't work.

Since that issue is happening even with a USB wifi adapter, you may have to resort to some other things like reinstalling W10.

Maybe there is something amiss with the HP factory image.

You may want to consider a clean install of W10 by making bootable installation media using the media creation tool.

Download Windows 10 (microsoft.com)

After W10 has completed installing, you can install the drivers and available software from your notebook's support page.

Hi,

Do I have to make a clean install via a bootable installation media or is it safe to just do the "Reset this PC" inside settings and select "keep files only" do you reckon? I'd only have to spend time installing key programs I need again

You have nothing to lose by trying that first.
