I had to separate the 5 GHz and 2.4 GHz for a smart bulb and ever since then my Roku 3920X Premiere won't find the 5 GHz wireless network. They both have different names, the channel is set to 157 ( have tried lower and higher channels) on the 5 GHz and automatic on the 2.4 GHz. It did connect fine before I separated them and everything else works well on both the 5 and 2.4, depending on the requirements for each device.
The 3920 is not a dual band capable device. It only supports the 2.4 GHz band with 802.11b/g/n protocols.
