Wifi only connects to home network

[LOLLIPOPSJSJSJ]

I have an LG G2 (D802) with Cloudy G2 3.3 Custom ROM and Dorimanx Custom Kernel loaded. The thing is I use two routers at home because the main one's wireless function is not working and thus I use a second modem for wifi and therefore connecting every device with static IP adresses. This is not a problem though, I could used to connect to any network with no problem but one day I don't know the reason but no matter what solution I tried, cleaning wifi lease, deleting all networks from system files, reflashing the kernel, it still only connects to only home network. I haven't tried flashing the ROM cleanly and the thing is I don't wanna format my phone right away if there's a solution. Help guys ^^

Connecting other networks using static IP adresses don't work either, I can't get a internet connection this way, says connected but no luck.
