Hello! I have Fiber 100MBps down/up service and I cant seem to get that using my 1st gen airport extreme. When I plug in via ethernet (On my fiances old school mbp with ethernet port) to the fiber port I get the 100 down/up consistently, but when connected via wifi on the airport extreme It tops out at 50 down / 35 up. Do I finally need to upgrade to take advantage? EDIT: This is sitting directly next to the router, nothing but 2 feet of air between the airport extreme and my rMBP. Thanks.
