Welcome to the forum and sorry to hear you're getting ping spikes. I've just checked your connection and everything looks healthy from here. Your power levels, SNR and area contention are all healthy. It would be worth setting up a broadband quality monitor at thinkbroadband.com. This will track your latency over 24 hours into a graph. Once you've set this up, give it 24 hours to populate then post a link here for us to take a look at it.
