The streaming chronicles (2/4)

In which I troubleshoot the Roku Express for a problem that so far has turned out not to be one.

I've been using the Roku Express for two months. I still recommend it as the most economical standalone streaming solution, though with some caveats. Namely that it thinks my router is physically located in another zip code.

A Wi-Fi analyzer placed next to the Roku Express never drops below -50 dBm on a clear channel. Full strength. But the Network > About screen lists the signal strength as "Poor" and the "secret" Wi-Fi screen (HOME x5, Up, Down, Up, Down, Up) reports a signal strength of -80 dBm.

("HOME x5" means to first press the HOME button five times. Click on the sidebar graphic for a list of the Roku secret screens.)

At first I thought Wi-Fi Direct, a Bluetooth-like protocol that communicates with the remote control, might be the guilty party.

The Roku broadcasts an SSID called "DIRECT-roku" on the same channel as the access point. With a Wi-Fi signal strength around -50 dBm, the DIRECT-roku SSID often peaked at over -40 dBm, which is like cranking the stereo to eleven and blasting it all over the neighborhood.

I program my AV gadgets to an IR universal remote (a big reason to prefer the Roku Express over competing models) and I don't need the mirroring functions. The following steps suggested by Brendan Long turned off the DIRECT-roku SSID on my Roku Express.

Go to Settings > System > Advanced system settings > Device connect and disable Device connect. Restart the Roku.

It turns out that "Device connect" is Wi-Fi Direct. Other than de-cluttering the radio spectrum, turning off Wi-Fi Direct didn't help. Neither did reinstalling the software (HOME x5, FF, FF, FF, RW, RW) or the Wi-Fi drivers (HOME x5, Up, Down, Up, Down, Up).

The software update might have improved the adaptive bitrate streaming protocols. It didn't affect Wi-Fi signal strength. But everything is working the way it is supposed to. My solution is to stick a piece of black tape over the "check engine" light and keep driving.

In any case, thirty dollars is simply not that big of a sunk cost. If it stops working, I'll take that as an excuse to play with other streaming toys. The next step is to implement some long-overdue upgrades to my home network and see what kind of a difference that makes.
