My mother has a Linksys E1200 wireless router and a late 2013 MacBook Air running Yosemite. She had to reset the Linksys router, and now cannot reconfigure the router. Cisco says to redownload the Cisco Connect software to proceed. But the software isn't compatible with Yosemite. The router is out of warranty, so Cisco balked at providing any support. Anyone know how we can get the router configured?
