I have the same router. Total POS. The dual band does not work. The 2.4 Ghz band is good for ~25 ft only. TRied using the 5.0 MHz for Streaming video band does not work at all. I reinitialize the software and it stops working soon after. I've completed all firmware upgrades. My kids use the 2.4 GHz for their games which sucks all the bandwidth for my work. My hardwired connectin is great at 130 Mbps so that is not the issue. If I'm doing something wrong love to know what and fix it.
