I have two access points, with the same SSID, same security mode (WPA/WPA2), operating at different channels (1 and 6). I have set the first of them (192.168.1.1) to operate as a DHCP server, while the second one has DHCP disabled, only having a static IP address (192.168.1.2).
My laptop connects fine to the second access point (when I'm in its range), receives an IP address, and always has connectivity to the Internet. My mobile devices (HTC Sensation & Nexus 7) connect as well, receive their IP addresses, but sometimes (usually when not active) they lose Internet connectivity, while maintaining full signal. When I check with Fing, I see that they cannot reach the main access point (192.168.1.1), and devices connected to the first access point. I have to restart the second access point for it to work again.
What makes me wonder is the fact that this never happens with my laptop. Am I missing something in my configuration?
