I have a first-generation Airport Express that I am using to extend my CenturyLink home wifi network. I hooked it up wirelessly, and it says it has a great signal from the router, but I’m not getting that great an improvement in my garage, which is about 20 feet from where I have the AE situated in my house. I have ethernet nearby and can easily run it to the AE, but is that going to help if I’m already getting a strong signal via the router? With ethernet, the AE can be configured as its own network, and if I use the same name and password as my existing network, it can “hand off” coverage as I move through the house. Will this help with the garage coverage I’m trying to improve?
