I am new to this Forum and happy to be a member. I have an Iconia A500 tablet with Android ICS that has been connecting to WiFi and Internet through a Belkin N750 router with no issues at all, it is setup to disconnect when it goes to sleep. For the past couple of months, a weird issue was happening, which caused the tablet to disconnect from WiFi an hour or so after the desktop (connected to the router wirelessly) is turned off or goes to sleep. When the desktop is turned on, the tablet gets connected to WiFi and Internet again. However, the tablet connects to networks elsewhere (other than mine) without problems,. I tried resetting the router, changing many of its settings even connecting the desktop to the router with a cable, rather than wireless, but all that did not solve the problem. It seems that the tablet gets its signal from the desktop not from the router. All other WiFi equipment I have, such as laptop, printer and others, work fine with the router regardless of the desktop status. Setting the tablet to be connected all the time, the connection remains regardless of the desktop status, but if the connection is disconnected for any reason, it can reconnect only if the desktop is turned on. Recently, after a six-hour power outage, when the power was restored, and the desktop was turned off, the tablet was able to connect to WiFi without any problem. However, after turning on the desktop, the same problem came back. It seems that the problem is with the desktop and not the router. Did anyone experience this issue before? Any help will be greatly appreciated. Update 11/21/2013: By pure chance I was trying to disable some start-up programs to enhance the start-up time and memory usage, I disabled the "Control Center Launcher", which is a software that allows communication between the desktop and a Brother multifunction printer. Since installation of the printer driver and software, I did not need to use it at all. After that, the tablet started to connect to the router with or without the desktop being turned on. It was not possible to predict that since there is no visible connection between the tablet and that software. I hope this information can help someone with this particular circumstances. Again, I appreciate the help I received from the Spider and Mrhelper.
