My boyfriend and I, live in a 529 square feet apartment, and we have a Belkin Wireless N150 Router since about two years ago. We experimented problems with the wireless, like slow speed, which we solved by disconnecting the router and connecting it again. Also, signal was from too weak to none at all, on our bedroom, so I decided to buy a range extender. Now we have a Belkin N300 Range extender, we configured it and it works well at the beginning, but after one day or half a day signal begins to drop in the room, sometimes devices are connected to the extender and it says there is no internet connection. Also there seems to be an IP conflict between my boyfriend's Android Tablet and my iPad. I checked on the router settings, and it displays that DHCP Loans does not expire, but some devices (iPad and Tablet) does not appear connected, then we reset all the networking devices (router and extender), and we forget network and put the password again, and it happens the same. We have also tried turning on the wifi of every device we have one by one just for the router signal, and afterwards do the same were we only receive the range extender signal, and it works fine for a while, but afterwards we have the same problems all over again. I don't know what else to do. Can someone help us?

Please Help.
Thanks !

I didn't find the right solution from the internet.
