Came home from a week of traveling to find my phone and bedroom laptop not being able to resolve DNS over WiFi. Restarted router - CG3000DV2 / N450. It's worked fine for over a year or so... Connected work laptop over ethernet and all pages load quickly. Changed channels on router, "forgot" network on phone, etc. Finally did a factory reset on router and connected to default SSID. Internet loaded fine on phone. WAT. Then changed the default SSID to a new custom SSID (not the old one). Works fine. Changed it back to the SSID I had before. DNS could not resolve. Again, WAT. Both SSIDs are not the original SSID. Both are hidden. Both are on the same channel. Why would my router/ISP block one SSID from resolving pages over another? Any ideas??? I'll stay with the "new" custom SSID but it's definitely annoying.
