Regular ping spikes to my router

[mabogo]

I have regular ping spikes to my router both at home and at school. So I think this rules out my router being the problem (also every other device on my home network is perfectly fine). I confirmed the problem was ping to router by using windows command prompt:  

It goes from 2-4 average to 2000+. I have the problem on both 5G and 2.4G. This problem has been going on for a while on my 15-dw0033nr notebook and I was able to temporarily fix it by uninstalling network drivers and restarting. It would work fine for about 2 days then go back. This temporary fix no longer works at all. I talked to HP support and their advice was update network drivers and BIOS. The first time I did this it was fixed for about a week before going back, the second time it didn't make any difference so they told me to contact my ISP but I don't understand why two different ISPs in two different locations would give just my computer problems. 

I thought it was another application on my computer taking up too much bandwidth periodically so I tried to look on Wireshark, but from there it seems like my computer just stops all network activity for those 2ish seconds of the ping spike:  You can see that there is delay of about 2 seconds between that ping request and the next packet which is captured by Wireshark that's unrelated to the ping while all the ones after that are less than a second. I know there are some things the OS or network card just doesn't report, but the frequency of these is way higher than normal.

Network Card: Realtek RTL8821CE 802.11ac PCIe Adapter. Driver version 2024.0.10.210.

I also have full warranty if this is a hardware issue, but I really hope it isn't so I don't have to send my computer away for who knows how long. 

Thanks in advance!

I understand that you are facing issues with the network.

Go to device manager and expand the network adapters (be it Realtek or Intel)

Right-click on the wireless network adapter and select properties.

go to Advanced tab and change the following values and save your settings:

802.11n channel width for 2.4GHz connections to 20MHz only.

Preferred Band to 2.4GHz.

Roaming Aggressiveness to 1.

Wireless mode to 802.11b/g.

This solved the problem but restricts me to only 2.4G wifi. Is it possible to have 5G at all with this fix?

Thank you for the update.

I have checked the manual. 

Your module support Integrated wireless options with dual antennas (M.2/PCIe) Realtek RTL8822BE 802.11ac 2 × 2 Wi-Fi + Bluetooth 4.2 (MU-MIMO supported).

The wireless module is not a user-replaceable part.

You have to contact our phone support or a local service center for replacement.

Have a nice day!!
