My apartment has AT&T Fiber. My phone is showing 310 mbps down, 51 up and 13ms latency, but my 5 year old desktop, with the TL-WN881ND, is showing 0.38 mbps down, 1.39 up and 40ms latency, both tested with Googles speed test, both through Atlanta servers, and I was holding my phone about an inch away from the antenae. The card is advertised to handle up to 300mbps, so I'm really not sure what the reason is for the discrepancy. I've reset the router, moved the computer from below the desk to on top, while also positioning the antenae towards the router. Do I just need a new card?
