This extender works extremely well but is not easy to set up. You need to adjust the proxy settings on your computer/laptop etc . Warning do not use the helpline. They tried to scaremonger me into paying £199 to “clean” my brand new laptop and enable the extender. I took the laptop back to Currys who sorted the proxy settings in 2 minutes and set up the extender - no charge !! So go ahead with the purchase these small extenders are great but don’t get trapped into completely unnecessary expense
