Wireless real slow - What can I do to fix it?
-
I am trying to connect an iPhone to my pfsense router. The connection is real slow. What are the ways you guys would go about troubleshooting the problem?
I have set the wlan0 interface set to access point. I know there is no interference like a fish tank, microwave, or cordless cell phone. I own none of those things. I am using the alix board and pfsense 2.0.2. I had it working fine with version 2.0 but after the upgrade something went wrong and I had to start all over from scratch.

Does the iPhone get an IP address from pfSense?
Please post the output of pfSense shell commands```
/etc/rc.banner; netstat -i; ifconfig; ping -c 10 w.x.y.z -
Here is the output of the command:

By the way, I used this command:
/etc/rc.banner ; echo " " ; echo " " ; netstat -i | grep ath0_wlan0 ; echo " " ; ifconfig ath0_wlan0 ; echo " " ; ping -c 10 172.0.0.15I thought it would cut out a lot of the unnecessary stuff.
It seems that all devices that connect to the wlan interface all have the same slowness problem. -

You are not comparing like with like. A full duplex wired interface can talk whenever it wants. A WiFi device generally has to wait its turn because it has to share the communications channel.
