I just bought the Archer T4U today to replace my previous wifi adapter. It works fine and my internet connection has improved. However, when I open certain programs, the network starts to become laggy and unstable. For example, I am having an issue connecting with the game Roblox, despite having a 180 Mbps download speed. Not only that, but it happens when I am using Discord and Steam. I tried several methods to confirm that it is not the issue of the programs.
