Last week, I bought a new PC. I use the fastest speed of Internet I could get from Spectrum. However, my PC gets horrible Wi-Fi. When I run a speed test from my PC, it fluctuates from 0 bps to 30 mbps within 10 seconds, and sometimes it will lose connection to the internet altogether (I lost connection twice while typing this out). Whenever I run the same speed test on my phone in the same room, I get 100+ mbps. Can anyone help me? Wired internet is not an option as my house does not have the ports for it.
