My typing was slowed, and I was having loss of internet connection. Didn't matter using my phone, Office, or on here. A computer guy at a big box store told me to get rid of my N type modem and router. With smartphones, tablets, laptops, PC's and now smart TV use all in the same house, too many things are trying to get connections. Amazing the difference we saw after replacing our 6 year old modem/router. Plus, I clean out the cache on a regular basis using ccleaner. This is what worked for us.
