i bought a Linksys WIFI expander from Amazon. your tech (quite an accent) After waiting a long time, tried to make it work but finaaly said it is defective and I should return it and I did so. I then bought a more costly Linksys WIFI range extender C7000. I waited hours again and this time i could barely make out the speech of the tech. He tried to register it but said the serial # is wrong on the item. He made it seem like my fault that the serial # did not work after trying many times. This has been a horrible experience to me and wasted many hours of my valuable time. I am 94 years of age and so my time is real precious. Do not buy from Linksys. The help is terrible
