When my clients going through the airport on my small business network to access the internet, the performance speeds are up to 10 times slower than those clients connected to a switch on the same subnet as the router and cable modem.
Here's the setup:
I have the Airport setup so that it's LAN interface has an ip of 10.0.1.1 and it's wan interface is 188.8.131.52 with default g'way of 184.108.40.206 (i.e the router). My cisco 1700 router then has LAN interface of 220.127.116.11 and then it's wan interface as the public wan ip address connected to the dsl/cable modem. Airports WAN interface and router LAN interface are connected to the same switch.
However the clients on the 10.0.1 subnet have a slow internet connection.
I have tested having a client connected directly to the switch on the 172.0.1 subnet and it's internet connection is almost 10 times quicker.
Therefore it seems like the bottleneck is the airport. Are there any config settings on the airport that I could tweak, or is there a quicker, more optimized setup that I could have?
