Wi-Fi & connectivity

[goodnightIrene]

ATT upgraded me to fiber optics on October 4. The tech moved the router from the den to a middle bedroom.  All Rokus were working fine until October 21 when the Roku in the den stopped connecting. My other two Rokus are fine, but they are now closer to the router. I have tried all troubleshooting suggestions multiple times: turn off router; turn off Roku; reboot router. I still get Error 14.30 on only one Roku, the one in the den. ATT says there is no interference and no congestion. ATT enabled 2.4 but still the Roku could not connect. I need help.

The 14.30 error is usually because the 2.4GHz wireless mode isn't set to b/g/n.  You may be able to make the change yourself or ask AT&T to do it.
