I have a Samsung Android tablet with Wi-Fi connection issues the tablet pick's up a very strong Wi-Fi signal from my own Wi-Fi router but it keeps scanning for Wi-Fi and acting like the signal has been lost when there is still a strong Wi-Fi signal.

Thanks, Spider, I am done with your link and solve wifi problem on my tablet. Such a stupid I am because I ask every one to get Linksys router support to for better wifi connection and solve network issue. I think there was a problem with my router but a router is ok. And your support is really helpful to me.
