Wifi up to 30mbps on phone but only 5mbps on PC

[olsp500]

Hello, I have a problem with my wireless wifi adapter card. On my phone (next to my PC) I run a speed test and get 30mbps +, while on my PC i only achieve 1-5mbps. I think the issue is my wireless adapter. I have a TP-link TL-WN881ND adapter @ 2.4Ghz... I think it because my phone supports 5Ghz and my adapter does not. Do i need a new adapter or is there some setting I can change?

Thanks Ollie

that adapters max speed is 300Mbps so I am not so sure

Maybe its the location of PC in relation to router?
