Media Bridge - 5GHz over CH 48

[Cumulonimbus]

Hello,

using 3.0.0.4.374.33_beta3 (Merlin build) on two AC66

1. AC66 - Router
2. AC66 - Mediabridge

First AC66 is setup with

nvram set pci/1/1/ccode=US
nvram set pci/2/1/ccode=US
nvram set wl0_country_code=US
nvram set wl1_country_code=US
nvram set regulation_domain=US
nvram set regulation_domain_5G=US
nvram commit

to use Channles obove 48

The 2. AC66 (Mediabridge-Mode) was setup also with this Settings, but the first AC66 can't be found in search-mode.

Any Ideas?
