I am connected to Internet by router 2811 of Cisco. My connection to Internet is Eth from the provider and I want to connect an additional line to Internet to anther provider.
can i use "Hwic 4 esw" card ? or it is a risk in the use of this "Hwic 4 esw" with regard to the Internet?
HWIC-1FE is a wan routed port and has better wan QoS capability than the Hwic 4 esw which is a switch port. If it is a simple internet connection with no QoS the "Hwic 4 esw" is good enough.
