Observation of unusual data transfer during one game session.
Observation of unusual data transfer during one game session.
Sorry if this should be shared in networking discussions, but I thought it would be better to address it here first. I've been experiencing a problem for roughly a year or less when playing multiplayer servers in Garry's Mod. From what I understand, no other game seems to have the same issue, but joining a server in Gmod causes my network bandwidth to drop from around 460 Mb/s to about 60-70 Mb/s. Most other games only use about 10 Mbps or slightly more, and it seems like my whole network is impacted, not just my computer.
I'm connected via Ethernet as well, and the issue persists even on WiFi. I've tried disabling downloads while playing on Steam, lowering the server browser pings per minute from 5,000 to 1,000, and using a VPN, which hasn't helped much. I haven't found any documentation about others facing similar problems. Checking the task manager shows my network usage stays very low—just a few megabytes when in a server—so it's unclear where the bandwidth is being consumed.
Any advice or assistance would be greatly appreciated.
(Additional details: My ISP is Spectrum, I use an Asus router from a third-party manufacturer and an Arris surfboard modem. My PC runs Windows 10 and is connected via Ethernet.)
Check the available models for modem and router using "ipconfig /all" in the Command Prompt. You should be able to view the details without any issues.
Do not share your Public IP address or MAC information.
Avoid posting your IP address.
Refer to Resource Monitor and Process Explorer (Microsoft, free).
One or both tools might show background processes such as updates or backups.
Task Scheduler could also be involved.
Take your time examining the results; no rush is needed.
Router logs may provide additional clues if they are enabled.
Identify who has administrative access to the router for further assistance.
Hello, thank you for your message. I was under the impression I had fixed the problem and perhaps overlooked my comment here, so I’ll make sure to revise it for future reference. After switching from Windows 10 to 11, my network performance has improved noticeably. I’m currently experiencing about 210 megabits per second on average, which is a significant increase from the previous maximum of around 60 Mbps. However, my ping remains high, ranging between 120 and 250 milliseconds. Further investigation, including a bufferbloat test, suggests that latency issues are present under optimal conditions during data transfer. I’ve checked the modem I’m using—it’s an Arris SURFboard SB6190, which hasn’t changed in several years. Looking into it more closely, it appears this model’s CPU may be causing the latency. On the other hand, the router seems relatively recent, so I suspect the problem lies with the modem and might require replacement. Since I didn’t verify the model after learning about the device, I’m inclined to focus on replacing the modem first.
