Q: We replaced our old router with a Linksys model to improve TV streaming, but now our HP printer won't stay connected to our iPads and MacBooks via the Wi-Fi network. We have to restart the printer before every use. What's wrong?

A: Because you print via the Wi-Fi network, the problem may be caused by incompatible settings on the new Linksys router and the HP printer.
Apple suggests you use these router settings (for details tinyurl.com/hvpggaq):
• Set a dual-band router to use both the 2.4 gigahertz and 5 gigahertz communications bands, and make sure it uses the same "network name" for both bands. Otherwise, some devices may not connect to Wi-Fi. (The network name is often referred to as its SSID, or "service set identifier.")
• Set the router to use all versions of the Wi-Fi communications standard. This helps eliminate electronic interference on the network and make sure older devices can connect.
• Turn off MAC (media access control) address filtering, which is a way of limiting who can connect to the Wi-Fi network. Instead, regulate who's allowed on the network by using security settings. The strongest security setting is "WPA3 Personal."
• To maintain network compatibility, make sure the router is set to automatically download software and firmware updates. (Firmware contains operating instructions that are kept inside a particular device.)
