My router is downstairs and my PC is upstairs so I'm using a US300 MSRM wireless repeater to make my computer have better ping, but over time, I have been getting a lot of ping spikes and just bad latency in general. It has consistently been above 3ms, with the occasional 200 ms ping spike. I've tried flushing my dns, restting it, Network reset, putting in other DNS, but I'm wondering if it's something to with my hardware. Could someone help me out?
