I am having trouble connecting the Amped Wireless AP600EX access point to my WRSV4400n. As soon as I plug the range extender into the router, instead of it receiving an IP address, it crashes the router. I have updated the router firmware to 2.021. I have checked the box in the WDS menu to "allow wireles signal to be repeated". I will check with Amped, but are there any known issues between this router and the Amped Wireless family of range extenders?
