And the phones report?

[The system logs keep saying this:

What has MAC address of f8:1e:df:5e:9c:84?

Where would I find what the phone reports?

The iPhone has that MAC Adress.

I guess that depends on the phone.

Right now I'm using an iPhone, so I'm not sure where. But the problem is still there no matter what phone I am using.

If I ping the iPhone, I get some really strange results:

And now the Laptop on the same AP:

Signal quality issues? Do phones work better if closer to AP with only air between AP and phones? AP using a crowded channel? (WiFi Analyzer is a free Android AP which will give useful indications of signal strength and WiFi channel occupancy.)

Encryption negotiation problem? Phones work without encryption configured?
On my Android 2.3 phone if I go to Settings -> Wireless & networks -> WiFi and then turn on WiFi the phone reports "Connecting …", "Acquiring IP address ... ", "Connected to ..." etc.

rocketdog

Like topic says, it's either signal quality, or it completely drops the phones.

I've been trying lately both with and without WPA. But it still gives the same result. What does "using a crowded channel" means?

I will purchase the wifi analyzer later today and check it out.

Thanks

@rocketdog:

Your AP is transmitting on a channel also used by one or more other "nearby" APs.

rocketdog

Changed to channel 3 now, which I seems to the only one using.

Tried to monitor the signal strength with Wifi analyzer, and at the same time pinging the phone.
The pings are really up and down, and sometimes it gives time-out, while the signal is just smooth.

Here are the results:

A ping from my Android 2.3 phone to my pfSense AP upstairs: in 62 pings the RTT (round trip time) min was just under 4mS, the average 12.5mS and max 21.4mS.

In 62 pings from the pfSense AP to the phone, the min RTT was 3.9mS, average 64.6mS and max 118.6mS

Your times vary considerably more.

@rocketdog:

3 is the only one not in use?

802.11g spreads across a number of channels to get more bandwidth. Channels 1,6 and 11 are the only one with no overlap so it would be best to use one of those if you can.

Sorry. I'm out of ideas on this except that you try to get more information out of the phones.

rocketdog

Now I've tried all channels, but without result. Still don't know how to get any "verbose" information out of my phone.

same problem here with another usb wlan stick. did you find a solution?

srynoname

for the records and googling people: my android device has a problem with my rum driver based usb wlan stick, but not with my old atheros based linksys wrt54gl router. so maybe switching to a device with atheros chipset and driver helps (note that the wrt54gl runs linux, not sure how similar the driver is to the one supplied by freebsd!). only problem with this: no atheros usb sticks! ):

Hello, I have the same problem. Did you find the answer for this issue? In my case It seems because I am not authenticating, so my phone disconnected every 2 minutes.., But my computer does not have problem If I authenticate or not. Any ideas?
