I have 1 pc (lets call it PC1) with internet via a 4g usb dongle. this PC is connected (hardwired) to a Linksys e1200 wireless router. This router controls wireless network between 4 PCs and wireless printer (it has dhcp enabled).
My problem, I'm not able to configure router internet section(that is usually auto populated by ISP modem) and PC1 to share internet for the wireless network.
on PC1 I've tried to bridge internet connection with Lan, but doesn't allow me, I must be missing something.
I have a scheme of 192.168.1.1 on the wireless router - all PCs pick up IPs from router between 100-150.
should PC1 be connected to LAN or WAN port on router.

any help would be greatly appreciated. If I didn't explain my self, of if I missed some information let me know. I'll do my best to explain the setup
