Q: Airport Express connection speed
I have 40 mbps internet speed down. I have a new Century Link modem (recently moved in to the house - new internet service) feeding my airport express. Up until a couple days ago I was getting all 40 mbps through my airport express wirelessly. Now it is capped at 10 for some reason. The only thing that changed is that I had to power cycle my modem to reroute a couple power cords in my basement. When I plug my computer in to the same ethernet cable that feeds the airport express I get the full 40. I tried restarting everything. I tried every manual 2.4 ghz channel on the express (I have not configured 5ghz because I really don't need it right now). I am not sure why its running at 10 rather than 40 as it was a few days ago.

FWIW, the AirPort Express base station's Ethernet ports are 10/100 Mbps. When it bridge mode all Ethernet ports on the base station, are just that, Ethernet ports. No routing functions (DHCP or NAT) are enabled.
In theory, with the Express connected to your gateway, any other Ethernet device connected to the Express should be getting at least a100 Mbps connection.
What I would suspect is that the Ethernet auto-negotiation between the gateway and the Express is not happening such that the gateway "sees" the Express has a 100 Mbps connection. Looks like Port 2 on your gateway is having the same issue.
