Hi, I have a tp-link MR600 router which I use with a SIM card. It’s a 4G+ router. I live in a house that has lots of concrete walls and I need a hybrid mesh (combined WiFi range extenders and power line) to reach all the spots in the house. Do you have an affordable system that you could recommend for my situation? The reason I need hybrid is that power line only works when the power cables are part of the one circuit which I have on one level of the house but the other level of the house can use a WiFi mesh component for better speed etc. Thanks for your help, I know it’s a complicated situation. Any particular product combinations or kits you sell would be appreciated. I live in Portugal.
