Upgrade the wifi card driver and the bios on the WiFi router. Upgrade the router if it is old.That's my cable internet over Wi-Fi benchmarks
Should be enough but still it's unstable.

Might consider another package ...
Another router and an ethernet cable
WIFI channel should be fine as there's no one around me.
Networkcard should also be fine (Dual-Band Wireless-AC 8265)
