I recently changed my wifi so I have full fibre. It works on my phone but on my pc nothing has changed.
For my PC when I game I use a TP link wired ethernet connection, more specifically the TP-Link TL-PA411 Powerline Adapter, AV500, I receive less packet loss compared to when using just my Wi-Fi adapter which is the TP Link Wireless MU-MIMO USB adapter where I get faster speeds but more stutters in game.
I usually switch to my Wi-Fi adapter when I am downloading/browsing and switch back to my ethernet for gaming.
It's become unbearable playing competitive games on my wired ethernet and having to keep switching from ethernet to my Wi-Fi adapter.
What I want to know is why is it like this and what I can do to get less packet loss?
I am using a cat 5e cable.
Ethernet TP link is plugged directly into a wall too.
Not sure if it matters, but when testing network speed both phone and computer were in the same room.
