I was using wifi for some time and finally switched to cable. My router is about 15 meters away from my pc. I see no difference in gameplay. Pings are still the same (high). Do I have to change some settings in my router? Does it have to do something with length of cable and maybe type of it? (Cat5)

I'm looking for set of a brand new skates for my wmo.
Are PureTrak HD any good? Or should i go for Hyperglide skates?
