Q: Very slow speed despite full connection
Hello,
Setup
I own a latest generation airport extreme running 7.7.3 firmware a latest gen macbook pro with Airport Utility 6.3.6. I have fiber through my local fiber internet provider. The connection comes straight into my apartment and plugs into my airport's WAN port. When first setup or after a few restarts, my macbook will get 250-300Mbps down over my 5Ghz connection. When I plug my MacBook directly into the ethernet I consistently get 600+ Mbps. This is expected.
The Problem
Whenever I check my download speed my download is choked to 25-50Mbps over 5Ghz, it's even slower on 2.4Ghz. I have full connection on my device, sitting only several feet from my router. After restarting (sometimes I have to restart a few times) the download speed jumps back up to the 250-300 I expected. I should also note that this has happened with two different ISPs. Before I had fiber and with my most recent fiber provider, so I feel confident isolating the device as the problem, not the service.
What I've Tried
- Setting DNS to Google's 8.8.8.8 and 8.8.4.4
- Changing the 2.4 and 5Ghz Channels
- A separate 5Ghz network
- Calling my ISP

Any suggestions? I'm scratching my head and I can't find any similar posts to my specific problem. My internet is not disconnecting, it's just really slow for what the ISP is sending over the pipe.
