My question is i have the short fatter router/modem for my internet. i was told when i changed to the 300 that i needed the tall thinner one to handle all the devices in my home and get the best speeds. I chatted with a man who told me that the one i have is the best and should be able to handle all the devices. Our speeds are terrible. Do i need the taller one or is the one i have the newest and best. If it is then there is some kind of problem i would think. When i changed from the 150 to the 300 they were supposed to send me the tall thin router/modem but they sent the exact same one i have. I called and the lady said they would send me the right one and to take the last one they sent back. They said i would have it by that thursday . i chatted with a agent on friday and he said that they never put that order in .IT has just been a big run around.
