Hello, I have a Huawei B353 Wireless router running of the 3moible 4G network. It woprks great. My phone and ipad connect to it via WIFI no problem, and my tv is connected vioa one of the 4 ethernet out ports and is running fine.... but I am having problems sending a signal to a second router via ethernet that I am using to extend its range. I bought a TP-Link Archer C6 AC1200 wifi router assuming I could hook up an ethernet cable from my Huawei to the TP-Link's Internet ethernet input and use the TP-link at the other end of the house to run things when I'm out of the Huawei's range. Unfortunately it does not work. Can you help me please? Have i bought the wrong device to support the Huawei? I need both ethernet and wifi in both wings of my home. Many thanks, Ben
