           Summary: Card doesn't connect to the AP
           Product: prim54
           Version: 1.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Device Driver
        AssignedTo: prism54-devel at prism54.org
        ReportedBy: miroslav.sulc at startnet.cz


I have problem with Z-COM XG-901 card. It is claimed that it is supported by
prism54 so I suppose there is a problem with the driver and not with the card.
Here is the description.

I cannot make the card to connect to AP (Z-Com XI-626). I think I am doing
everything right but with no success. I use the same cable and antenna with
different card and the card connects to the AP. I can even scan the air with the
XG-901 and the APs that show are correct. I use gentoo-2.6.9-r9 source with its
prism54 driver (as module). The system is Gentoo.

Here is the card info from lspci:

Almost each time I now run the iwconfig there is another channel so it seems
it's looking at every channel for the AP.

I use the latest firmware but I have tried all the previous.

Here is output from dmesg:

Loaded prism54 driver, version 1.2
ACPI: PCI interrupt 0000:00:0b.0[A] -> GSI 19 (level, low) -> IRQ 19
eth1: islpci_open()
eth1: resetting device...
eth1: uploading firmware...
eth1: firmware uploaded done, now triggering reset...

I cannot use wavemon because of this error:

bash-2.05b# wavemon
fatal error: could not get range information

When the card searches for the AP (or what is it doing), iwconfig shows link
quality changing from 0 to 97 and it doesn't matter whether the antenna is
connected or not. When the antenna is connected, the values of link quality are
in the full range specified, but when the antenna is disconnected, the values
change between 80 and 97.

In error log there is everything OK, maybe except this message:

[net.agent] add event not handled

but in fact I don't know whether this is a problem.
