Model: Adapter  
Hardware Version: V5
Firmware Version: TL-WN821N

I got a new pc (win10) and an older laptop (win8.1)

I use the tp link adaptor to connect to the internet.

Playing the same online game, I get lag spikes every 3-4 seconds on the pc, while on the laptop I get none.
I believe I have installed all the neccessary drivers.

Why could this be happening?

@MadHoly Good day, 

 

May I know did you disable the self built adapter on laptop when test tp-link adapter?

Does the ping lag if you use the self- build network adapter on laptop when connected to the same Wi-Fi?

 

You could try this chipset driver for TL-WN821N V5/ V6 and see if helps:

If issue persist, please help confirm some details that will help to locate the problem, much appreciated!

  • May I know does the issue only happen when you play online games , how about web browsing or any particular game got this problem? 
  • Does the issue happen on  2.4Ghz or 5Ghz?  What is the model of main Wi-Fi router? 
  • Can you share us photo of the motherboard info and driver date and lag/ spike results, thanks!

@Solla-topee Greetings

 

1) I disabled the wifi from the laptop, the tp link adapter shows up as wifi2 and I only used that, these are the results

 

 

as you can see with some minor spikes it's pretty consistent

 

If I use the built-in adaptor the ping varies wildly and is generally worse.

These are the ping tests on my new pc:

The ping spikes are CONSISTENT, every few seconds. This answers another of your questions, these lag spikes are what I perceive in games, web browsing is fine and I don't notice problems but games (I played paladins and dawn of war soulstorm) online every few seconds freeze up and then resume.

 

I believe I can only run in 2,4 Ghz since I don't remember finding a 5Ghz option on my network settings.

The router model is

Router TP-Link Archer VR400 Modem VDSL2/ADSL2+ Wi-Fi AC 1200Mbps

 

Here is the driver on my new pc

 

Motherboard is an optiplex9020

 

 

PS I unzipped the chipset and ran a ping test and the results were the same

@MadHoly Hello, 

 

You mentioned  ' If I use the built-in adaptor the ping varies wildly and is generally worse.'    Does this mean it could the issue on modem/ ISP side, not the issue TL-WN821N?

Just to double confirm, if not using TL-WN821N, is there any Ping lag issue ? 

 

If Modem has the high lag problem you could try suggestion in  this FAQ : 

What should I do if I get the high ping value from TP-Link Wi-Fi router?
https://www.tp-link.com/support/faq/2723/

 

> Please wire a PC to VR400 moidem by Ethernet cable and play game, and see if there is any high ping on wired connection? 

> If the problem is only on wifi, you could login VR400, enable 5Ghz wifi and change a different SSID for 5Ghz, and see if the issue on 2.4Ghz 5Ghz

You could try a different channel/ Channel width for that wifi band and test performance

Here is an FAQ to login to Modem : https://www.tp-link.com/support/faq/1200/
