Yes - I ordered the new 4G Samsung extender, recieved it within 24 hours (Sat. - that was pretty cool) and tried to install it yesteday. Spend hours watching it hang up on step "11b of 14." Per instruction manual called and spoke to a VERY nice and helpful cust serv. rep. about 4 times (she was good enough to call back to check in), but we never got past 11b which she said was some kind of "software update." Hit the reset button, changed the router port, blah blah blah. She said she could see that my 4G exdevice was communicating with Verizon. Per her instructions I am sending it back today.
