different ping between 2 pc Omen in the same network

[Angelo_bdb]

Hello everyone, I have this problem: my 2 Omen PC with windows 11 pro, connected to the same modem, have different ping and speed, precisely:
Omen 25L GT12 Intel i7  -  ping 3 download 834 Mbps Upload 312 Mbps
Omen 45L GT22 intel i9  -  ping 45 download 690 Mbps Upload 180 Mbps
What can be the reason? I state that I do not have antivirus in any of the 2 PC.
Thank you

The systems have slightly different network performance.  Both are identical 1gb hardwired LAN but the 45L has W-Fi 6 and 5.2 bluetooth not 5 and 5 respectively.

Do you have Wi-Fi configured and also an ethernet cable connected at the same time? It is possible that one system is wired and the other running wireless.

What are you pinging?  Site like google have more than one IP address and change it constantly.  Same for game servers.  If a game site had only one IP address it would be easily blocked by the first DDOS attack.

The DNS server determines where to find a site.  If a hardwired connection, the modem has the DNS primary and secondary addresses.   On the other hand,, the Wi-Fi can be programmed for any DNS server.

I suspect the DNS servers are differnet.  Here is what my win11 setup looks like.  It is only available for Wi-Fi as there it no setting for DNS when I am hard wired.  

Make sure both system have the same DNS information

[EDIT] You mentioned you do NOT have an antivirus.  It that a mis-statement? 

Windows 11 comes with defender which is difficult to turn off

Many game sites (servers) have been hit (supposedly) with the log4j virus but that can happen with just 1  hop as no need for 45 to get to a bad server.

Hi, thank you! I'll try to check Dns.

I have used speed test by Ookla.

Both pc have an ethernet connection with wi-fi disabled...

(of course i have win defender but not other antivirus like McAfee for example)

I'll let you know

@Angelo_bdb --  I state that I do not have antivirus in any of the 2 PC.

Really? Windows 11 includes the "Windows Defender" antivirus software.

Have you disabled that software?

How are the two computers connected to the modem? WiFi? Ethernet cables?

If using two Ethernet cables, swap the cables to the other computer, and re-test, and tell us the result.

Was either computer updating (Adobe Reader, iTunes, Windows Update, synchronizing with OneDrive, etc.) while you were doing the testing?

@BeemerBiker / @Angelo_bdb -- The DNS server determines where to find a site.  

Correct.  But, after a DNS-server has returned an IP-address for the game-server, that server does not participate in any way while your computer(s) are running any "speed-test" software.

Compare to telephoning to a friend, to get the telephone-number of their friend. Once you have obtained the telephone-number, you use that telephone-number, not the telephone-number of the friend. And, you can "forever" use the newly-acquired telephone-number -- you never again need to telephone your friend, to get the same telephone-number.  Of course, if that friend's friend switches their telephone-number (such as changing to a different cell-phone provider), you must again telephone your friend, to get the new telephone-number of their friend.  On the Internet, each answer you get from a DNS-server comes with a TTL ("time-to-live") value, indicating for how many seconds/minutes/hours that the result is valid to be used.

Hi,

sorry, of course Windows defender is enabled, i meant that i haven't other antivirus like McAfee for example.

Both pc are connected with ethernet cables.

With the cables swap the problem remain...can a pc restore be useful?

thank you

@Angelo_bdb -- can a PC restore be useful?

Never say never. It might work, but it's not the first thing that I would try, especially if the "restore" will delete all my Personal Files and the apps that I have installed.

Instead, consider buying an internal network card, and installing it in one computer, and configure that computer to use that card, instead of the "integrated" network adapter.  Run the speed-test.

Remove that card, and connect it to the other computer, configure,  and run the speed-test.

Since both computers are now going through the SAME network adapter (but, obviously, not at the same time), your tests will be comparing/contrasting the two motherboards. 

Hopefully, this will give you additional insight.

Problem solved by restoring the pc, thanks everyone for the help.

See you soon

@Angelo_bdb -- Problem solved by restoring the PC ...

Great! 

I still suspect that one computer was "busy" (processor & Internet) while you were running the "speed test".  But, we'll never know.
