Question Ping issues on PC

[KeyRoll]

Hi, so a week or two ago I noticed ping spikes on servers that run at ~20ms, but then jump to ~700 momentarily. My wireless adapter works on other computers but not mine, and It's been working on my computer for a few months prior without any issues. Any suggestions will be appreciated
