I have bought a new tp-link TL-WA850RE range extender and have tried installing it and connecting it to my router. I could not connect it through pressing the WPS button on the router so tried the second method of installing through my PC. I have followed all instructions, named the SSID with a different name than my home network, kept the same password and continued with the wireless setting process until getting a congratulations notification teling me I can now connect to the extended network. Hoever, the RE light in the RE device did not light up and I could not connect through the RE network to the internet. I have tried resetting the RE device several times but without any change in the result. Would appreciate advice on how to resolve this before goign back to the store to replace the product... Thanks
