    Hi,

    If i connect an ethernet cable into my GPON from the ISP i get download speed of 300Mb/s. The GPON connects with an Airport Extreme latest gen 2014 via ethernet cable CAT6 (1.5m long). If i run a test speed via ethernet through the Apple Airport i only get 220Mb/s. So i loose 80Mb/s though my Airport extreme. I tried different cables but i got the same results.

    Any tips for troubleshooting please?

    What is the make and model number of your ISP's device?

    The GPON is a Huawei Echolife HG865, which gets its connection via fiber from the ISP.
    Any tips? :)

    Not familiar with that one. It's not a router handing out DHCP, is it?

    Hmmm.
    I wonder if the HG865 is providing DHCP, and the AEBS is also providing DHCP?
    Is the light on the AEBS green? or amber? If amber, I would suspect double-NAT, so you could try turning the DHCP off on the AEBS (or the HG865? Turn off DHCP on one device, just to see if that will help…)

    Hi blackfang,

    How is your network setup? Ie, is the AE in bridge mode, or, have you put the modem in bridge mode and setup PPOE on the AE?
    How do you authenticate onto the network?

    Sounds like, as stated above, that you've probably got a double NAT situation, but a reduction of 80mbps is a bit, so it's possible there is something else. I personally find that the AE isn't traditionally as powerful as other devices.

    Good luck,

    Phil

    The Huawei GPON isn't carying the DHCP. When i connected via ethernet with a laptop to it i had to manually add in my PPPOE settings (ISP ID and password). Only my Airport extreme is doing DHCP.
    The GPON is just a modem that converts my fiber signal to gigabit ethernet output. There are no AEBS lights on the GPON.

    My Airport Extreme connects in the settings with PPPOE ISP user and password

    This sucks :( i feel so sad because of it. I got so many apple devices in my house. Imac 2013, 2 macbook pros, macbook air, ipads, ipods, iphones, 1 airport extreme and 2 express. Hope i might solve this. From my ISP i can upgrade from my 300Mb/s package to 500 or 1000Mb/s . But i was thinking if i loose 80Mb/s in such a low speed situation. I don't wanna loose even more speed if i get a bigger internet package.

    So the good news is, it sounds like you've got the network setup correctly! Which is great!

    However. I think before you call it quits, it wouldn't be a bad idea to try a different router, try something a bit more modern (that you can also take back to the shop if it doesn't meet expectations). Of course remember that you're going to have a decrease in speed when plugging in your laptop vs a router. That's just the nature of the game although 300 to 220 (10mb) strikes me as a bit much.

    If you don't have the coin to go out and buy a new router remember that getting almost 30mb per second is still amazing!

    EDIT: Wait. How are you connecting your laptop to the Airport Extreme? If wireless, use a cable then check.

    Good luck!

    All the mention speed tests are done via ethernet. At wireless i get even worse via 5ghz i get like 130-150 mb/s with a macbook pro mid 2014 i7. I don't want to change my router because i already got 2 more airport express and even though my network might not be operating to max speeds its very reliable and stable. I will hope to wait till Apple will launch a new gen Airport Extreme. I will keep in mind though i might ask for my dad's router for a test, he's got a TP-Link archer C7.
    Thank you guys for the replies. It makes me happy that people help :D

    Yeah, wireless will always be slower and those speeds don't surprise me :(

    Completely understand in regards to stability (still using a 2009 Time Capsule for wireless), best to borrow the TP-Link and give it a go when you have a free moment. If it's there, why not!

    No worries,

    Phil

    From what I've read a difference in speed can be caused by one device (Huawei) using hardware NAT and the other (AE) using software NAT. Software NAT is necessary, I'm pretty sure, to enable the router to provide the other services that it does (port forwarding, etc.) at a reasonable cost.

    Also, I'm reading that the AE is particularly bad at this for extremely high speed connections.

    Test the the other router but you might end up doing some research on which router is best for the situation that you have.

    Be sure to let us know what you end up doing. These high-speed situations are coming up more and more often and the information will be valuable.
