Orbi RBR760 DHCP Option 61 Special Character Input Client Identifier Field

I am hoping someone here can provide sone help after completely failing with Netgear CS which has been literally time consuming and pointless. I have a Netgear Orbi RBR 760 and I need to enter into a specific Client Identifier string into the DHCP Option 61 field. This string is provided via my ISP to authenticate with their service using a third party router. The string concerned requires me to input special characters including @ and | symbols. For some reason the gui will not allow me to enter any such special characters. I have an older RBK50 and this input and solution works fine I am running the most current firmware as of 4th September 2024. . In short please, can anyone tell me a method of entering a string with special characters into the DHCP Option 61 field of ‘anything@skydsl|anything’? I have tried multiple browsers and input devices. Thanks

  • Did you try a mobile browser?

    You say it doesn't let you input it. Does it give you an error? or not show?

      I have tried mobile phone and also Chrike and safari desktop browsers. The characters will simply not enter into that field when typed. I have even attempted to copy and paste the full string and it pastes but omits the special characters
  • Oh, dear.  You appear to have uncovered a flaw in the 760 firmware.  May have to "send it back".

    The User Manual regarding Option 61 is clear and makes no mention of special characters. (see page 24)

    https://www.downloads.netgear.com/files/GDC/RBK763S/RBR760_RBS760_UM_EN.pdf 

    I do not have access to a 760 router.  On an RBR750, I entered "my.dog@fun|one" into the Option 61 box. The router took it, "no problem".  So, if these special characters were accepted on an RBR50 and my RBR750, my conclusion is that the 760 firmware is defective.

     

    Another option might be to beg the ISP to give you a string with no special characters.

      Thanks and I tend to agree on both a software glitch and the return aspects. There is no other strong available unfortunately
