Problems with AP mode

I am having major problems trying to set up my router in AP mode. Using an R8000 in conjunction with a Juniper SRX240 router   I was previously using the R8000 for home use, but my network traffi...

    description of which "The documentation" is being discussed, too.

       Agreed.  Just like complaints about "The documentation".

       Ok.  That's a reasonable way to configure an R8000 as a wireless
    access point.  (Up to a point.)

    one myself - this makes sense. Unfortunately in my firmware, V
    1.0.4.18_10.1.49 I don't have that option. the only option I have is

       I haven't touched an R8000, so I know nothing, but, on other models
    (like, for example, my D7000 (V1.0.1.64_1.0.1), and an R7000
    (V1.0.7.12)), checking the box at "Enable Access Point Mode" reveals the
    "Choose IP Address settings on this access point" choices, as described.
    Scrolling down doesn't help on yours?

       Around here, the default choice is "Get dynamically from existing
    router", and that works only if the router-as-WAP can talk to a DHCP
    server on your network, which it can't do if it's not connected to your
    network.

       Those names work only if the R8000 is acting as a router (and DNS
    server), and should fail if the R8000 is acting as a WAP.

       Similarly, if the R8000-as-WAP is getting its LAN IP address
    "dynamically from existing router", it would need to be connected to
    "existing router", and neither of those addresses is very likely to be
    the address it would get if it were.  (And, if it's not, then it will
    have no LAN IP address, only frustration.)

    > [...] I have no idea where the router is.

       It won't "Get [its LAN IP address] dynamically from existing router",
    until it's connected to "existing router" (DHCP server).

       What, exactly, "does not work".  If you're trying to get your web
    browser to talk to the R8000-as-WAP, then you'd need to know its
    address, and, so far, only the main router (DHCP server) knows what that
    is.  If the main router offers some kind of Attached Devices or DHCP
    Clients report, then that should show the R8000-as-WAP, and the address
    shown there should lead to the R8000 managment web site.

    > [...] I have also tried to set up the router in router mode to a fixed

       "in router mode", the R8000 has two IP addresses, WAN/Internet and
    LAN.  As usual, showing actual actions with their actual results (error
    messages, LED indicators, ...) can be more helpful than vague
    descriptions or interpretations.

       Given the existence (supposed for you, actual for me) of that "Choose
    IP Address settings on this access point" choice, I'd guess that a
    manually set router-mode LAN IP address would not survive the change to
    WAP mode.  I'd guess that you'd get either the default ("Get dynamically
    from existing router"), or else whatever you specified for "Use fixed IP
    Address (not recommended)" when it provided places for user-specified
    values for:
          IP Address
          IP Subnet Mask
          Gateway IP Address
          Primary DNS
          Secondary DNS

       So, if your R8000 really doesn't ask you to "Choose IP Address
    settings on this access point", then I'd assume that it's defaulted to
    "Get dynamically from existing router", and I'd ask the "existing
    router" (DHCP server) where the R8000-as-WAP might be.

       You should, but finding the R8000-as-WAP may be a little less
    straightforward than you might expect.  But, aside from the missing
    "Choose" choice, it should all make sense if you look at things from the
    point of view of the R8000.
