I'm installing 2 wireless phones down/up stairs. I'm using the rj-11 connection on the back of antenna, then punched on pins 2 and 3 on ksu. It keeps saying no link to ksu downstairs, i don't have the other one installed yet. Is their anything i need to check, if i plug a phone in their it works great. This is for a house and only using 2 c.o. lines. Thanks for any help
