I am a new customer and just received a Grandstream adapter. This adapter appears used, it's a bit beat up and is missing 2 of the 4 rubber feet on the bottom. Not exactly sure why, but once the adapter was put on the network I started having DHCP issues. Not sure if this adapter will issue DHCP addresses, but my experience has been that it does or at least interferes with my routers DHCP leases.
Bottom line, I'd like to replace it with a Linksys PAP2 v2. The vertical stand alone will help clear some space on my rack and I've had good experience with the Linksys and other providers.
Do I have to go through support to make the change or is their documentation with the settings necessary.
