Can't stay connected to Linksys RE1000 extender after upgrading to Yosemite

Ever since upgrading to Yosemite I'm having trouble staying connected to the WIFI network that I have extended through a Cisco (Linksys) RE1000 Wireless-N extender. It was working fine prior to the upgrade to the final version (even through all Yosemite preview versions).

I've reset and resetup the RE1000 and I continue to have the problem. The WIFI seems to work fine when I connect to other WIFI networks, it's just this one for some reason.

Anyone using one of these?
