Regular Ping Spikes with Realtek RTL8821CE 802.11ac PCIe Adapter

[Zed100]

Hello!

I have issues with regular ping spikes on my HP Laptop 17-by2xxx with Realtek RTL8821CE 802.11ac PCIe Adapter (version 2024.0.10.209).

Every 10th to 11th ping is very long (I checked with ping -t 8.8.8.8) and this makes my video-conferencing very irritating, since every 10s there is a short freeze of the video.

I am quite sure that the problem lies with the Wi-Fi adapter in my laptop, since:

- there are no problems when the laptop is plugged directly to network,

- other notebooks and tablets do not experience any ping spikes within the same wifi network.

I searched quite a lot around about the "ping spike" topic, but have not found any conclusive instructions about what to do to resolve this issue. I followed the HP trouble-shooting instructions, I removed the adapter from the system, then added it back, I deleted drivers, reinstalled them, etc. Nothing worked. I even experimented by changing all the available configurations of the adapter, but to no avail. 

Many thanks for your support in advance.

Kind regards, Z.

I checked again all proposed solutions for this issue within HP community, and this solution provided by TEJ1602 posted on 23.9.2019 worked for me:

Follow the steps below-

In your windows cmd, type in

netsh wlan show settings

and one of the last things might say

Auto configuration logic is enabled on interface "Wireless Network Connection"

if that's the case, then type in

netsh wlan set autoconfig enabled=no interface="Wireless Network Connection"

It should respond with

Auto configuration has been disabled on interface "Wireless Network Connection".

If it doesn't, then you might have mistyped your interface=" part. Check in your adapter settings, you might have Wireless Network Connection 2 or 3 etc.

This will definitely stop your wireless card from searching for nearby networks and updating your signal quality when you're not asking it to- which is what is causing the spikes.

The only problem with this solution is that you need to manually turn this functionality off and on again if you want that your laptop connects to the wifi network. Any ideas how to simplify this issue?

So to turn it off you need to use the following instruction at CMD:

netsh wlan set autoconfig enabled=no interface="Wi-Fi"

and then to turn it on again, you need to enter:

netsh wlan set autoconfig enabled=yes interface="Wi-Fi"

Quite tiresome to do every time one uses the laptop.

Any ideas how to facilitate this?

Many thanks!

Hello!

This information might be of interest for users with similar problem. With the help of a specialist in the MS community, I was able to identify the culprit for ping spikes / latency, using the clean boot procedure and problem elimination, as described here:

In my case the problem was caused by an application which automatically runs at start up, and is used for digital signature of documents, submitted to our tax authorities through their web portal. When I disabled it from start up, the problem disappeared.
