I have a new Airport Extreme hooked to fiber optic internet service. There is no modem in the equation. ISP provider said there is no modem used with this service. I have good internet when hooked direct to ethernet cable. The extreme flashes the amber light and gives two errors, no internet and no DNS. I can connect to Apple TV throught the network that was set up. If I switch to bridge mode, I can get limited wifi, but still have the errors. Any help? I hate the thought of going out and buying a non apple product to do the routing. I have done multiple factory resets and setups.

    Hi - this is new technology which does not require a modem - the fios comes to your house and is split in a type of media converter into internet via ethernet, video and phone - so what you get is ethernet as if it came out of a modem or router - that is why it works directly with your computer - but now is where it gets tricky because I have experience with DSL, Cable and T1 lines but this is new to me - so based on the above info, the Extreme should be configured as if it connected to a non-Apple router - so if you haven't tried it already, set it up as a bridge (DHCP off) connected via ethernet and choose "create a wireless network" and give it a name and password of your choice - the security type should be WPA2-personal - and be sure to check "allow wireless clients" - you won't be able to have a guest network but it "should" work - please note the quotes as this is pure theory on my part - and for future reference, please let me know if it works.

    Sorry but I just realized that it might not work but I would try it anyway - if it doesn't work then you should treat it as if it is a modem and enable DHCP and share a public IP - so it wouldn't be in bridge mode - the rest would be the same - in this case you would be able to have a guest network - and you might have to do a factory reset between setups if the device gets confused - again I am sorry about this but it is an interesting question and I like to try new things - and unfoutnately I also like to do things by trial and error - that is the way I learn.

    I just had similar issues with (in my case, Verizon FIOS) fiber optic Internet service when replacing an old Verizon-provided D-Link DI-624 router. I had to re-attach the DI-624 router and release the DHCP lease with ISP. Then hooked up the Airport Extreme and it now works fine as normal router (did NOT need to be set as a bridge).


    If you have no router that holds a DHCP lease, you may have to call tech support with your ISP, explain what you want to do and ask them to release it for you.


    Good luck.

    Thank you for your response - I hope that Srcooper02 sees it - what you say makes sense - and I am sure that there will more questions as this technology becomes more prevalent so I am going to save this post for future reference.

    Thanks again,

    Thanks for the update - I am sorry things didn't work out - but I hope that your effort was not in vain and that the Apple people pass it on to their engineering dept and they do something about it - this technology is the future and Apple will have to adapt to compete - in order to get 2 fiber optic T1 lines working in my case, I had to sit on the phone with the ISP tech and put each value into the setup manually - it was tedious but it was worth it - I now have an office with 2 parallel LAN's consisting of 8 Extremes and 2 Expresses - they work great - this is why I was trying to help you.
