In my house, I have the following setup:
Ground floor: My ISP's wireless router and an 8-port switch. For wireless communication I use the ISP's Wifi and the 8-port switch is used for wired rj45 sockets around the house.
1st Floor: I have a TP-LINK TL-WR740N Wireless Lite N Router 150 MBps which I connected to a socket and have a PC connect with wire on it and also used for Wifi. The Wifi network I setup on the 1st floor is different than the one on the ground floor (2 routers).
At the first floor I have the problem that in other bedrooms far from the router the Wifi signal (either gets lost) or it's very low. So I bought a TP-LINK TL-WA701ND Wireless N Access Point 150MBps which I configured as universal repeater.
1st issue: The access point supports only WEP encryption when used as repeater/universal repeater so I changed the wifi of the router to WEP with ASCII with 128bit character length and established the connection.
2nd issue: The most important now is that even though the Wifi signal in the bedroom with the AP is full, when I switch off the wifi of the iPad and back on, it is not connecting to the internet. Yesterday I noticed that it was giving me the ethernet card IP (169.…). I went close to the router with the iPhone, got connected and when came back to the room with the AP it was working but the iPad is not working.
Can I fix this without having to buy any other hardware?
