Troubles reconnecting to WiFi network
Hardware in use, within the home:
1 x 2-wire 2701HGV-W WiFi modem/router downstairs
1 x TP-Link WA501G upstairs (configured as AP, DHCP disables, static IP 192.168.0.20 - outside assignable range of router)
2 x NP285's connecting the downstairs router to the upstairs AP over mains power lines
Both router and AP configured with same SSID, on channel 11 and 6 respectively, using WPA2-TKIP with AES encryption
Although I can connect to the Wi-Fi network successfully and surf the web or file share between PC's or from iPad/iPhone, I seem to have a problem reconnecting if I loose Wi-Fi connection or choose to "Forget this network", say from the iPad, after connecting upstairs and then trying to reconnect when I go downstairs.
Intriguingly, I seem to have no problems if connection is lost downstairs and reconnection is attempted after moving to the upstairs location!
It's almost as if the router takes some time to relinquish the initial IP address -vs- MAC association of the iPad/iPhone/PC etc. (if initial connection occured via the TP-Link AP) before allowing connection attempts to proceed. While in this "limbo" state, attempting to reconnect from say, the iPad, continually presents the "please enter pass-key" prompt.
Although this "limbo" period appears to be far shorter than it was when I had tried separate SSID's on both upstairs and downstairs, it still poses an issue and one that I's like to understand and try to eliminate, if at all possible.
Incidentally, I've been reading about how poxy the 2-wire 2701's are so I wouldn't be surprised if it had something to do with this unit's slow DHCP service, or such like.
Appreciate any thoughts?
