Around 6 months ago, I set up a wireless network composed of an airport extreme - as the main base station, connected to a router - and an airport express to extend the network into the other room.
Just to be sure I understand your current network configuration, are all of the following true?
- Both AirPorts are 802.11n models.
- The AirPort Extreme Base Station (AEBS) is directly connected to the "main" Internet router by Ethernet.
- The AEBS is configured as a bridge and to allow it to be extended.
- The AirPort Express Base Station (AX) is connected to the AEBS by wireless.
- The AX is configured to extend the AEBS' wireless network.
Thank you for your reply.
- Yes, both AirPorts are 802.11n models - AirPort Extreme 802.11n 5th Generation and AirPort Express 802.11n 2nd Generation;
- Yes, the AirPort Extreme Base Station (AEBS) is directly connected to the "main" Internet router by Ethernet;
- No, the AEBS is configured as DHCP and NAT - this was set up automatically;
- Yes, the Airport Express Base Station (AX) is connected to the AEBS by wireless;
- Yes, the AX is configured to extend the AEBS's wireless network.
I decided to change the physical location of both AEBS and AX. The internet connection oscillated widely and has since stabilized around the contracted broadband speed. But I am not sure it will continue steady as it is now: it recorded from 2.0 Mbps to 122 Mbps, stabilizing in 50.0 Mbps, which is what was contracted.
No, the AEBS is configured as DHCP and NAT - this was set up automatically
Correct, that would be the default configuration for the AEBS.
Unless this is your networking design goal, the AEBS should be reconfigured as a bridge. This will allow the upstream router that it is connected to to provide both the NAT & DHCP services so that network clients connected to any of the routers will be on the same network subnet. When two or more routers connected in series have NAT eanbled, you will have what is known as a "double-NAT" condition. This is not necessarily bad in itself but does cause other complications.
