I have an Actiontec router from Verizon using FIOS. I have been waning through information all day but cannot resove an issue relating to the Airport Express (AEXP) I turned off the wireless signal from the FIOS router and am using the Airport Extreme (AEXT) for the wireless signal while still using the actiontec for DHCP. It works fine until I try and add the AEXP and select it in the Airport Utility, something happens and the EXTR stops working also. Once I disconnect the AEXP I can get the AEXT to work again. I had read that it had something to do with the Action tec router and security but even after changing it to WPA (which I hate) instead of WPA2, it didn't help. I am simply trying to extend the range with the APXP but can't get it working. If someone has successfully done this, please advise. Seems like this issue goes back all the way to 2008 and so I can't believe that there is still now workaround for this.
