Can anyone help me?

On my desktop, using a D-link DWA-110 adapter, I'm getting around 1-3 Mbps on speedtests while on my laptop with its adapter its getting 9-10 Mbps. I'm using VIP10 btw. So I'm left to wonder if its the adapter at fault but when I think about it, it shouldn't be so bad to the point of me just having 1-3 Mbps should it?

And if it is the adapter being the problem, any recommendations on which USB adapter to get? Heard DWA-160 is something to look at.

I'm getting 2-3 out of 5 bars for signal strength. Speed hovering between 18 and 24 mbps.

Oh and Unifi was just installed like yesterday if that makes a difference(shouldn't be because then my laptop wouldn't get those speeds)
