My Kindle Fire HD 8.9" 4G LTE Wireless 8.9" HD Display, Dolby Audio, Dual-Band Dual-Antenna Wi-Fi, 4G LTE, 64GB will only run on one band at one time.
If I select the 2.4GHz band it will log me in on 2.4GHz Band. If I then select the 5GHz band the Kindle drops the 2.4GHz band and logs on to the 5GHz band. The same thing happens if I select 2.4Ghz Band it will log out of the 5GHz band and then log on to the 2.4GHz Band.
I thought "Dual-Band Dual-Antenna Wi-Fi" allowed access to both Bands simultaneously thus requiring dual antenna's.
The 5GHz Band does not pass through many walls before it's signal drops to low and the 2.4GHz Band is extremely crowded (14 to 18 routers are strongly broadcasting). My wifi analyzer shows my router is the only one on 5GHz.
My router is dual band. The Network Name (SSID) for each band are labeled differently so I know which Band my services are connected to i.e. Shaka5Ghz for 5GHz Band and Shaka2.4Ghz for the 2.4GHz band.
My new dual band Kindle only works with one channel at a time. I paid $614 for this Kindle because it was advertised as dual band. The only reason to have dual antennas is so you can use both bands at the same time.
