So I've always had super slow upload/download speeds. Recently however, I upgraded to a 400Mbps internet plan, so it is definitely faster (before at like 70mbps at best.) However, recently I've experienced decent packet loss (around 23% average) and way slower upload speeds compared to download. My ISP is Spectrum and my Wi-Fi adapter is a Realtek 8812BU Wireless LAN 802.11ac USB NIC. Any ideas?
