TP-LINK wireless connection PAD4 unstable solutions (original) - for optical fiber Internet users: After IPAD4 open wifi, search and connect a wireless router, it will break after 5-6 minutes, then turn wifi only close , you can re-access, but continuous 5-6 minutes and then will break, and the computer can be stably wireless Internet access. IPAD4 version: ios6.1.3 (currently up to date); TP-LINK Version: TL-WR841N V8.0 version, and firmware has been upgraded to; Solution: 1. Hardware connection: As the cat-routing function, therefore, light cat network interface cable should be connected out of TP-LINK's LAN port (ie four one yellow port) rather than WAN port; 2.TP-LINK Setup: LAN port IP amended as 192.168.1.2, restart; (key? ? Step) set to a dynamic IP (not PPPoE); (critical step) router with DHCP off:? DHCP server --DHCP enter service, the DHCP is set to not open; (key step) to modify the SSID to a different name (? such as letters, numbers, etc.);? designated channel 1 or 11, do not use automatic;? mode selection 11bg mixed;? Close WMM;? Close QSS;? to the radio network set up encryption, it is recommended to select WPA-PSK / WPA2-PSK Encryption type, select the encryption algorithm AES, and set the PSK passwords; After setting, IPAD4 to ignore network reconnection. In addition, it is recommended to use wireless LAN router closer connection signal, for comparison testing. Are some of the considerations above method, after consultation with telecommunications and TP-LINK technology services summary, key steps must be set as required. I am hoping to help!
