Can't ping 192.168.1.1 on WIFi

Have a TP-Link TL-WR1043ND that I pirateboxed. It was working for a while but last time I checked it, DHCP was giving out 192.168.1.x addresses on the WiFi, but strangely I could not route to 192.168.1 (ie. cannot ping; cannot browse).

However if I connect to a LAN port with an Ethernet cable, I also get a 192.168.1.x address but I can route and browse OK.


Any ideas for me?
