Hi, I set up my Range extender RE315 by pressing the WPS button on the router and then the WPS button on the extender as described in the installation guide. It works fine with an Ethernet connection, but the password to access it via Wi-Fi does not appear to be the same as the router despite the claim that it should be. I have tried the original wireless key that the router came with as well as the current one. It just says incorrect password. The router is a technicolor TG588v v2. Thanks for any help.
