Question Latency Spikes On A Wireless Connection

[Bandhu]

I have been having network issues, on my pc only, the issues persist for a few days and then die down, but reappear randomly, additionally the issues don't persist for the entire day, but rather several hours at a time. The problem I am having is latency spikes. These spikes can occur from anywhere between every 15 seconds to 2 minutes. The spikes often last for multiple seconds, in the form of smaller ping spikes. My ISP is spectrum and I have the spectrum fiber plan which is 1gb/s. I have some graphs from running the ping plotter software:

I have made some changes to my network settings trying to fix this;
2.4G Wireless Mode: IEEE 802.11b/g/n
5G Wireless Mode: IEEE 802.11a/n/ac
802.11d: Disabled
Beacon Interval: 300
MAC Randomization: Enabled
Multi-Channel Concurrent: Enabled
Preamble Mode: Short & long
Roaming Aggressiveness: Disabled
Wake on Magic Packet: Enabled
Wake on Pattern Match: Enabled

Hopefully someone can help me solve this.

You are very limited in things you can try.

It is the standard. Try using the 2.4g band and the 5g band and see if one is better. You can try changing the channels on the router for each band and see if that makes any difference. You can also force the channel width to 20mhz and then try other channels. Note setting the channel width to 20mhz will likely result in a slower connection but it might be more stable.

This is a extremely common issue with wifi. It is generally interference from devices both inside and outside your house.

In general unless you get lots of packet loss it will not affect most application. The exception is online gaming which is extremely senitive to packet delays. This is why they say to not play online games on wifi it is to unpredictable. Even if you get it to work your neighbor could come home from work and start watching netflix on his wifi and interfere.

You also might note all kinds of problems when the kids in the neighborhood come home from college for the holidays.

The only real answer is to not use WiFi and used wired connections instead.
