In my workplace, the ADSL / internet line (which is connected to a TP-Link router) is down, so I need to use a USB 3G broadband modem to give other computers internet access.
I was wondering if there's a way to make the router use the broadband instead of the telephone cable, keeping in mind there's no USB port on the router.
Note: We use the router as a default gateway for the domain computers, so it's easier to do this than using a broadband wireless router.
Thanks in advance.
