I recently bought the below TP-Link wi-fi extender to fix some dead spots at my home. I have a TP-link AC1200 dual band router and this extender paired well. However there is a significant reduction in the bandwidth/speed now. I have a 300Mbps connection and after connecting this extender I get around 100Mbps to 150Mbps speed only in my laptop. Will the speed drop like this or did I get a faulty extender or should I return and exchange with something else?
