Last night i started having my connectivity probs again. I am at a loss and have no idea what to do next. So if you have any idea please let me know. All hardware is new and I have the highest connection Xfinity has available in this area. When I do speed test it maxes the meters out. Yet when I am trying to do anything it acts like the old dial-up connection I had years ago. When it does connect it runs fast like normal then within 5-10 seconds it is squelched don't to no connection to do anything with. We have tried different ports and a new CAT6 cable. The only thing left is to try the new PCie internet adapter I bought, but the realtek one is brand new as the motherboard is brand new. Please help if you have any suggestions what I can do to fix this once and for all.
