I currently pay for 100mbps but I am only getting 10-20 for download,I contacted my isp and they ran a couple of tests and told me my modem was defective but after telling them that my modem was not capping my speeds,they told me that my router was the issue considering that when I am connected via Ethernet I get 80-90 mbps so it was just the wireless of the router.What kind of router do you guys recommend for me to buy?
