I live in student housing in a separate apartment from my university's dorms. We have complimentary wifi but my Roku LE can not find my apartment's network, even when I try putting it in manually. My network band is 5ghz if that has anything to do with it.
Someone, please help, I can't keep using my mobile hotspot
This seems to be a very recent Walmart special for which I can find very little info. But my guess would be that it does 2.4GHz only. Roku's low-priced models tend to have that limitation and this is the lowest-priced yet.
From what I understand, the Roku LE (Limited Edition) is a white version of the older Roku Express. The older Roku Express devices are 2.4ghz-only band devices (no 5ghz capability). The new Roku Express 4k/4k+ devices are now dual band devices (both 2.4ghz and 5ghz capability).
The Roku LE will not work without a 2.4ghz connection.
I just found out that Walmart is having a $15 Black Friday sale on these while looking into your question.
Feel free to post back with update or if you have more questions.
