As the subject states, I cannot connect to my RE450 settings via computer or any other device other than the Tether app on my iPhone, which doesn't have the options that I need. I have my RE450 setup in WAP mode and it is working. There is Internet connection and I can access the Internet through it when I connect to either the 2.4 or 5GHz networks. However, I cannot connect to the device via my computer. I've tried from varioous computers, which are connected to my network via ethernet, and I've tried via a laptop connected to the wireless networks created by my RE450. Nothing works. I've tried 192.168.0.254, which is what the instructions say should be the ip address. I've tried tplinrepeater dot net, and all that brings up is an instruction page telling me to use the stupid Tether app that won't allow me to do more than the basics. How do I access setup for this device from a computer? I need to change the network security. I keep getting warnings that my extended network has weak security and I need to change it, but I can't do anything.

Any ideas?
