I have tried everything to fix my problems. My internet is great 90% if the time, but that other 10% is driving me insane. I only see it in gaming, creating near unplayable conditions due to lag/rubberbanding.
Have tried 2 different modems, and 2 different routers, isp keeps telling me it has to be my equipment because they see nothing on their end and everything checks out fine when they come to my house and hook up their little diagnostic meter. I have had a new drop to my house, and ran a new cable from where the drop comes in to my modem. Replaced all other cables as well. This has gotten to be so damn frustrating...
