Internet performance worse than other PCs on the same network
Internet performance worse than other PCs on the same network
I’ve been experiencing lag while playing Diablo 4. At first, I thought it was my apartment’s internet, router issues, or Blizzard’s side. I tried disabling cross-play and that helped, but the problem persisted. When playing alongside my cousin on the same network, I noticed I was lagging while he wasn’t. Also, during a Discord session, my audio didn’t reach my friends even though the mic test worked fine for me. This happened in menus when my CPU was low and network usage minimal. Connecting to the same Wi-Fi on my phone fixed Discord issues, but searches would still take over 10 seconds.
I mostly use Ethernet, but I’ve also tried Wi-Fi with similar results. My Lenovo Legion 7 refurbished from May 2022 is connected via an old Linksys E2500 router. I’m open to sharing more details if needed.
Typically I'd blame the wireless issue, but if you're experiencing the same problem with both, it might point to something within your machine itself. This often suggests a software-related problem, whether it involves interactions with your network stack or issues with drivers.
You might want to download the newest drivers for both your wireless and ethernet connections, then remove any third-party software that interacts with your network—like firewalls, monitoring tools, or network card utilities. Uninstall both the ethernet and wireless adapters together with their associated driver software. Restart the system and if Windows installs some base drivers, test with those first; otherwise, install the correct driver and retest.
Additionally, you could try using latencymon to check if a specific driver is causing the trouble.
To see what issues might exist, try visiting run userbenchmark.com and sharing the resulting link, such as https://www.userbenchmark.com/UserRun/28977730. Reset the BIOS using a jumper to clear CMOS or JBAT, then adjust boot priority afterward. Verify system integrity in Windows. Launch the command prompt with admin rights and execute DISM /Online /Cleanup-Image /RestoreHealth. Follow the instructions on https://www.lifewire.com/how-to-open-an-...pt-2618088 and https://answers.microsoft.com/en-us...em...5b60477a93. Perform a clean boot to help diagnose the problem in Windows 8.1, Windows 8, Windows 7 or Windows Vista.
According to Lenovo, my drivers are up to date, but there’s another way to verify. To locate network-related processes, sorting by network usage in Task Manager might help. When uninstalling network adapters, it appears you’d need to reinstall them first. Latencymon highlighted certain driver files as top ISR routines and DPC routines, recommending disabling CPU throttling. My power settings are set to high performance, which may not be relevant. The link provided seems to indicate strong performance, possibly indicating a successful operation. It’s unclear what further steps are needed. The DISM command worked, but I’m unsure about additional testing. My hard drives appear to be SK Hynix, yet no dedicated tools were found for error checking after searching online. I ran chkdsk, which seemed clean, but it might still require more effort. I’ll continue trying and appreciate your assistance so far!
