Smartbro detects the MAC address of the computer unit. Kung ma change gani, it will reroute you to the smartbro portal. Now, in order to share your smartbro, you need to buy a router. The router is important because it will create a LAN and also assign internal IP addresses on each computer.
When you insert the cable (smartbro) towards your router, you will be brought to the smartbro portal. You need to login so that the portal will now update and use the new MAC address of the router. Also, if you haven't used the smartbro portal before, you need to call the agents and ask for your username and password. They will gladly give that to you. Just tell them you need to see your online billing.
You only need to do this once, kay kung in the future maguba imong router and you buy one, the smartbro portal will be able to login itself and adapt the changes.
I hope this helps.
