    I have noticed the following issue: as I keep adding new DHCP entries (using nvram+commit), after the reboot either:
    - 5Ghz radio turns on but no internet connection is being provided
    - 5Ghz radio turns on (in the webgui) but no signal
    - WiFi works fine but no DNS is resolved.

    Is it only me?

    rt-ac87u, latest merlin

    [SOLVED]:nvram show ...

    Have you run out of NVRAM? Random things may happen if that's the case.

    That's a very good question...how do I check this? I can only list and commit..but at the end of 'show' result I got the following:
    size: 63396 bytes (2140 left)

    Yep, that's the number. That's dangerously close to being full.

    duh! ;) I am sorry, I was not clear enough. Currently I got ac87u but will swap with ac86u soon. Couldn't find any nvram info on wikidevi

    Ah - here's my AC86U's output:
    Code:
    size: 70953 bytes (60119 left)
    
    And from Tools - Other:
    Code:
    Internal Storage
    NVRAM usage 71046 / 131072 bytes
    JFFS 12.05 / 48.00 MB
    
    Interesting that they're ever so slightly different...
