First download and run free software called SpeedTest or use one from local carrier. Comcast has their own speed test software. Record your ping, download and upload. Upload is always going to be slower. You want a low ping as well for speed and responsiveness in gaming. If pages are loading slow also need to clear browser cache and scan computer for viruses, malware, spyware. Spybot and Advanced System Care Free (all free) will help. Your computer RAM, processor speed, and strength can also make a difference. But in all AC routers are much better and faster. N routers are old technology but should stll load pages quickly. If you have recent computer with AC wifi you are dumbiung it down to N technology. AC Routers are not up to 3200 or more speed. I would upgrade router at this point to at least 1300 to 1500.
