I have an Aspire one NAV50 with Windows 7 starter. One time, when I turned it on, The icon for wireless connection doesn't appear anymore. Every time I try troubleshoot it, it would just say that there is an ethernet cable unplugged. And so, I connected it into the ethernet cable and it works fine. But when I tried it again on the wireless connections, it doesn't locate to any wireless connection. I've tried the ff on my laptop: restart update scan the laptop with MalwareBytes Fn+f2 by the way, last night, when I turned on again the laptop, the wireless connections can already be found. However, after few minutes, it went back to being unlocated again.
