Wi-Fi & connectivity

[Sunny355]

The Roku in my bedroom works perfectly, but the one in my living room closest to the router will work great for a time, but then out of nowhere have trouble connecting to my wifi, which shows “EXCELLENT” signal strength. We only use one Roku at a time, we’ve tried swapping them out, unplugging the router, restarting the Roku, everything. Please help!

What are your Roku model numbers (Settings..System..About [press OK]) and your ISP (internet service provider).  Could be a few different things going on here from interference, to band selection, etc.

@AvsGunnar  My model is 3920x, I have a few of them that I swap out with that model number. I use Xfinity Blast, and according to my provider I never come close to using all I pay for on it.

There is a known issue with Xfinity and 2.4ghz-only devices like the Roku Premiere 3920 due to firmware releases/updates made to their routers recently affecting the 2.4ghz band.   However, the 3920 does seem to experience some more disconnections than other Roku devices so actually may be the device and its wireless hardware internals itself.  (Since the swapping of locations does not remedy issue, I think it is likely that it is this Xfinity mode setting issue rather than your devices though, at first glance.)

Try using the Xfi app or enter 10.0.0.1 into a browser and Edit your 2.4ghz settings to reflect the below. (The known issue is requiring the network mode to reflect b/g/n rather than g/n).  However, you can also experiment with using different wireless channels to eliminate some interference as well.

2.4 GHZ BAND

1. Radio is On/Enabled
2. SSID (network name) is On/Broadcasting
3. Network Mode/Protocol is set to b/g/n (Mixed Mode)
4. Bandwidth/Channel Width is set to 20mhz
5. Wireless Channel is set between 1 and 11 (preferably 1, 6 , or 11). Try changing and using different channels. Roku cannot see or use 12,13,14.

* Restart both your Router and your Roku after making above changes.
