I've tried searching for help on this but I'm lost so I'll just ask here. I live in a mother in law unit about 30 ft from the main house. I don't have access to the house when no one's there. The current setup is: Cable modem into main house router into my AEBS in bridge mode. It creates my wifi network separate from the main house network. I then use an Express in my place to extend my network. At first this worked fine after the internet was bumped up to 150Mps. Lately however its has slowed way down and become very unstable. Am I better off extending the original network from the main house and then extend it again with the Express? How can I optimize this setup? Sorry for the confusing question.
