I have spent countless of hours searching for this issue but no one seems to have it. I'm using a PC that is wired and a laptop that is wireless. My you tube runs fine i can watch 1080, i can download without a problem but every 15 minutes to an hour i get ping spikes that last about 1-30 minutes in some cases and they are around 1000 ms and sometimes 2000. My usual ping is 66 ms, this is extremely annoying and I'm not sure but i think its my internet provider since my laptop gets the same thing.
