I couldn't get any answers in any of the other threads when I asked, so I made it's own thread so someone that has this same router could help.
Here is a comparison using inSSIDer and my new laptop around the house of the 2.4G on my RT-AC1900P and my new RT-AC86.
1900P with firmware 380.68.4 (142 and 142_5G)
AC86 with firmware 382.1.beta1 (FU_Neighbors_2G and FU_Neighbors_5G)...
RT-AC86 - Weak Wireless 2.4G
