Wi-Fi & connectivity

[Rewhans]

Just came home to all 3 of my 4k+ sticks not having network connect.

Issue: Won't connect to network after putting in passcode (error 01430)

Work in IT so did the standards.

Restarted devices, router, and modem-No change

Factory restored one of them. - no change

Verified other Wi-Fi devices are working as well as direct connect via desktop. - all working fine. 

Any suggestions?

@Rewhans 

Are these 3820 Streaming Sticks or are you generally referring to the streaming devices as "sticks"? 

Settings/System/About will provide the model number of the devices.  Also provide model number of router please.

[Rewhans]

2 are model 3820x and 1 is 3941x

Spent two hours with Roku X account in dms and sadly still didn't fix it. 

Can pass the logs to help so everything tried so far.

@Rewhans 

Certainly.  Post what you have tried so far.

Here is what I would try and verify since the devices listed are both 2.4ghz and 5ghz compatible.

1. Try and connect each device to a mobile hotspot (if available).  If connects to hotspot, then hardware is working and culprit is likely a network setting.

2. Make sure 2.4ghz band  is enabled on router to check 2.4ghz capability. [verify wireless set set to b/g/n (all three protocols), channel set between 1-11 (1, 6, 11 preferred, not auto), and security set to WPA2-personal/psk with AES encryption) ].

3. For the 5ghz band, your devices are DFS-compatible, but try disabling DFS (ch.52-144) for troubleshooting.  Try manually assigning a channel between 36-48 or 149-161.  Make sure you have n/AC enabled if using a wifi6 router.  Verify using WPA2-personal/psk with AES encryption).  The devices you listed cannot use wifi6/AX/WPA3 protocols so need to include wifi5 protocols.

4. On the passwords with both the 2.4 and 5ghz bands, try removing any special characters (use numbers and letters).  Should be throwing a 14.40 error is this is the culprit, but worth trying to exclude as a contributor.

Feel free to include the list of things tried, the router model number, and ISP (internet service provider).  Seeing a few reports now that some Xfinity-leased routers may be changing settings to use AX and WPA3 in the firmware. (or at least users reported they "touched nothing", and found these setting changed).
