Can't keep wifi connection active on home wifi network (Belkin), works fine elsewhere
I am writing to ask for help about a very specific wifi problem I am having. My iPad wifi seems to work fine on every network (that I have tried) other than my home network using a Belkin N+ router. At home, whenever I leave the iPad idle for a while (or don't use the wifi signal), the wifi connection seems to time out, such that I have to reset the wifi antenna to regain access. I usually do this by turning on and off aiplane mode, which resets the wifi and makes things work again. Resetting this way works, but it gets annoying when you have to do it 5-20 times a day. Over the holidays I visited two relative's homes and did not have this problem, and I also haven't noticed this problem on public wifi networks. When I lose the data stream on my home network, I still see "full bars" for the wifi signal.
I have tried MANY settings on my router to try to fix the problem, but have run out of ideas. I am running the router and iPad with the latest firmware. My Windows 7 laptop has no problems with the router (but my Vizio TV can't even connect by wifi, perhaps related?). Since the iPad works fine with other networks, I am guessing the router is to blame somehow - either in my settings or some firmware/hardware on the router itself.
I use WPA2 security on the network. I have tried WPA as well, but I do not consider WEP or no security to be acceptable solutions, so I haven't tried them. I have tried many other settings as well, but I am wondering if there's something I haven't thought of.
I hope that give a pretty complete description of my problem. Please share any ideas and tell me if I left something out.
