I’ve seen several discussions lately about upgrading routers and need help from the networking geniuses. We recently upgraded our Frontier Fios internet to 75/75 and it actually seems worse than before. We also have frontier Fios cable. Would like to get the Nighthawk installed but have no idea what we need or how to do it. Can anyone help? Willing to pay for the time and expertise! This is what Frontier just installed a couple of weeks ago.
