Wi-Fi & connectivity

[jackdashack]

I have an older 3930X Roku Express. For some reason it will now, after a couple years of connecting, will not connect up. Earlier Xfinity ran test on my router. Whether this is relevant I do not know but they cleared it up, stopped all or anything blocking and pronuounced it good. I had been having issues with the Xfinity Router rebooting at will several times a day. So I'll watch that, it's only been a couple of hours. But all other devices, now, older LG phone and new Galaxy s8+, a Chromebook and 2 windows 10 pcs all are fine on wireless and ethernet. So this older 3930X will not connect to a the good signal. So I have a brand new 3930X I bought because Prime requires this model or newer. But it's new in the package. I took it and plugged it up and same thing. Will not connect to the good signal here in the house. Of course no one is gonna talk and help me through this. Does anyone here have any experience with this issue? I would be very appreciative.

If you are receiving error code 14.30 or 14.40 error code and have a cable ISP gateway (Xfinity/Comcast, Cox, or AT&T) gateway), recent firmware updates to these routers over the past months have caused connection and streaming issues with Roku 2.4ghz-only devices. (Roku Express 3930/3931/LE and Roku Premiere 3920/3921).

------

Edit your 2.4 ghz settings and change your Wireless Mode from g/n to b/g/n.

Restart both your Roku device and Router after making the above change.

There's a known issue with Xfinity routers and Roku.  Ensure the wireless mode is set to b/g/n and not g/n.

The Roku Express model 3930 is a 2.4 GHz only device. It won't connect on the 5 GHz band.

Additionally, many report that the 2.4 GHz band must be set for 802.11 b/g/n for Roku to properly connect. And many ISPs, including Xfinity, has changed settings to g/n from an earlier b/g/n settings.

If Comcast/Xfinity has done that, your Roku Express may not connect. Check your settings, if you can. If not, request they change the setting to b/g/n.

Here is one of the earlier posts where similar thing happened.

The important thing is that you found the answer. It's not as important who get "credit" for it. I mean, we're not trying to collect points to win a Buick. Just glad you found an answer.
