I have a (wifi adapter?) the thing that goes into your pc when your motherboard doesnt have wifi. It is a tplink archer t5e. I used to get decent wifi speeds, but lately it has dropped down to around 100kbps which is a major issue for me. Ive even completely restarted my computer clean and it is still slow. I bought powerline adapters but they have not arrived yet and im still unsure whether i have everything i need for them to work in my house. I just want someone to help me speed up my wifi if at all possible. One cause could be the amount of traffic in my house since i have so many people and devices on the router. The router is an intel(r) Dule Band Wireless which is 5 ghz
