Ping Spikes From Router

I have been having ping issues using a USB wireless adapters. I have used ones from TP-link, Linksys, and D-link. All of them have lag spikes when I ping my router. No other device I have has these spikes. NOTE: I am testing all from the same location in my house. I have never had this problem using Ethernet, but I just moved houses and there is no Ethernet available in my room. I don't believe this is a problem with the router because I tested on three other devices (2 laptops and a phone) and don't have this problem.

Solutions I have tried:

  • disabling wifi-sense
    disabling Updates from more than one place
    updating drivers on all adapters used
    checked other programs sucking up network usage (there were none)


  • Comp Specs:
    cpu: i5-6600k
    gpu: Gigabyte gtx 1070
    mobo: asus 7170a
    os: windows 10
    usb adapter: tp-link archer t4u ac1200

Solution
This is just how wireless works unfortunately. Since you have tried multiple nic devices it is unlikely something like a driver issues. Since it worked on ethernet it is unlikely something in your computer.

It many times is impossible to tell why 1 device works fine and others have issues. It all comes down to how the radio waves flow though your house. It many times is interference from your neighbors which you can do nothing about.

There is little you can do, change wifi channels or try to use 5g rather than 2.4g or the reverse. It may work fine for a while and then have issues as your neighbors also make changes.

Pretty much you accept this as a limitation or your use something like powerline networks to avoid it. In...

Pretty much you accept this as a limitation or your use something like powerline networks to avoid it. In general powerline networks have much more stable ping times. Look for av2 based equipment since powerline is dependent on the quality of your electrical wiring and the newest devices tend to work better.
