Hope someone can help? I upgraded my ios from c870-advipservicesk9-mz.124-15.T8.bin to c870-advipservicesk9-mz.124-22.T1.bin, as per the software advisor. When I reload the router I am unable to get an IP address from my ISP, if I go back to 124-15T8 everything works great. Does anyone have any ideas.
Thank you in advance.
