I've tried resetting the hardware and everything. When I select "wireless" from the menu where you set up the internet connection, my wireless network doesn't show up. You know, where it says "select your network from this list". It's just blank. It worked fine before. Our PS3 and laptop have no problems with it.
What's going on with this thing?
happened to me as well after a power outage. Did a factory reset, and all is well.
except i had to re-link the roku account again.
currently it's saying "synchronizing with account", so hopefully i don't have to re-link all my channel store services!
(update) -- no. looks like i have to re-link my services. ugh.
