Hello,
>> I want to setup redundancy on two links, one is 100meg fibre and the other 100meg Wireless. I want to set this up with a 2801 and Ethernet module at one end and Switch at the other. Do you see any problems setting up Etherchannel on these two types of connection, they are both the same speed.
not recommended performance and reliability of wireless link cannot compare with fiber use it as a backup link with higher STP costs
Hope to help
Giuseppe
