My wireless network card causes dpc latency issues?

Question

My tp link wireless network card is working on my desktop computer but however when I run the dpc latency program it’s showing red lines, when I turn the network card off the red lines disappear.

I’ve tried uninstalling and reinstalling the driver in device manager.

Should I be concerned?

Answer 1

It's likely showing delinquencies because wireless is not a constant connection. Wi-Fi is radio frequency waves, waves that can be thought of as ocean waves because they're very similar. When you drop something gently in to water it causes ripples from the point of impact of the object hitting the surface of the water. Think of that point of impact as your router's wi-fi transmitter (antenna). The broadcast radio waves are the ripples. There's a strong edge to each wave of the broadcast and then weaker spots in between each ripple or edge of the broadcast, those weak spots are the red lines in a program like that. The only thing you can do to correct this is use a wired connection because a wired connection doesn't fluctuate like radio waves do. A wired connection is a constant and stable flow. This is why a wired connection is better than wi-fi.



No, you shouldn't be concerned. There's not much you can do about it other than use an ethernet cable (wired connection) instead of wi-fi.

Answer 2

If you are doing audio and video, DON'T, I repeat DON'T use any wifi period! If you must use wifi be sure your are using the fastest available. Newer ac works better than N, etc. Don't even thing about a G network! Also if you must use wifi connection be sure that no other user is on the system at the same time. (Remember wifi is 1/2 duplex so you are already at 1/2 the ethernet speed.)

Answer 3

the simplest reason could be continuously turning the lan on/off eg Power Saving settings. its is NORMAL for pc's to assume that turning off lan/wifi/other settings to save power is the default setting especially on a pc with a battery but a desktop should be set to NO POWER saving NO SUSPENDING and the bios should be set to ALWAYS ON, but you should confirm any advanced settings for any card as it may still IGNORE that general setting and turn itself on/off when it feels like.

Answer 4

To be blunt, you should be concerned that you are using WiFi with a desktop machine...

There is _never_ any good reason for that, & many reasons not to - it can only ever cause problems.



Use Ethernet cables and eliminate the WiFi. If you cannot run a direct cable then get some gigabit Homeplug adapters.





I'd guess you are trying to use an audio interface or DAW software?



Re. DPC latency overall, try to avoid any "software driven" interfaces and use those with built-in hardware buffering and control.

Eliminate all USB except absolutely essential items such an actual audio interface plus the keyboard and mouse - and you could swap those to PS/2 types if the motherboard has PS/2 sockets.



Spread the USB items over different controllers - eg. try the audio interface or any high-throughput item on a USB3 port even if its USB2 & keep other low-throughput items on USB2 ports.

Categorically avoid bluetooth keyboards and mice; basic wireless ones that don't need any special drivers should be OK but cheap bluetooth interfaces are often a major cause of problems.



Even some built-in ethernet devices are software driven, so using a decent "intelligent" ethernet card instead can improve things further.

eg. Something like this: https://www.ebuyer.com/148377-intel-gigabit-pro-1000ct-pcie-desktop-adapter-expi9301ct





Also with audio interfaces, try adjusting the buffer size; there is a "sweet spot" that gives optimum results - too small increases CPU load and is likely to cause jitter, too large increases latency.

Answer 5

It depends what the abbreviation DPC actually stands for. On the following acronym site:



https://acronyms.thefreedictionary.com/DPC



There are several meanings of the 94 DPC options it lists that could apply.



If your system is working as you want it to work, then you should probably ignore running any specific diagnostics. If I go to http://speedtest.net and run a test, then I might get a much slower speed than my ISP says I am getting. My computer does everything I want it to do. In fact, with the speed test tthe slow speed was caused by the test selecting a slow test server rather than any ISP problem. I manually switched to a different server and got the proper figures, then I switched back to the slow server and got the same poor results.



I gave this example to point out that unless you know exactly what a measurement means and how it is measured, then it is difficult to say whether there is a real problem or just a result that is causing no problem at all.



I hope this helps.
