I have an at&t modem connected to the mynet900. Then I have a wired connection to a mynet750 as an access point. The 900 has a desktop and printer hard wired. The 750 has a roku. We have a number of wireless devices. We’ve never had issues with the wired devices, but wireless devices constantly have issues connecting to the internet. Wireless is strong. What could be the issue? Do the modems just have to be rebooted constantly?
Have you tried setting the wireless devices with a static Ip. This will give you a more steady connection.
