I had WIC 1 ADSL card in Cisco 1841 router, right now I am having 4 MB internet link has connected to the ADSL card . I want to know how much bandwidth will support in this ADSL card. For Example Ethernet Card will support 10 MB like WIC I ADSL over ports will support ?
WIC-1ADSL only support up 12 mbps downstream, 1.3 upstream. These are theoretical value very unlikely to be found in real applications.
Your other question cannot be understood.
