On my Linksys WRT1200ac V2 with r52189, I had to change the antenna chains settings from "1" to "1+2" to restore pre-r52189 wireless speeds. _________________ Netgear R9000

I'm glad to see a concern for this router again, congratulations to everyone for their involvement, I'm optimistic about ddwrt in the support for this router!
simple modification on wrt1900acs v2 to Protection Mode everything seems ok, I will try to run these settings for two days to see how stable it is, RX Antenna Chains 1+2+3+4 ran stable 2day!
