Problem with HostAP/WEP running in Managed mode
Thu Nov 18 12:16:37 PST 2004
I'm having problems getting the HostAP driver to connect in Managed mode
to an Orinoco AP-200 AccessPoint configured for WEP.
Before I get into the details, here's a bit more configuration info:
Platform: Pepper Pad2 Tablet; XScale PXA270 CPU running MontaVista CEE
Linux 3.1 ( a 2.4.20 kernel w/some 2.5/6 features back-ported by MV ).
Wireless Extensions: v14
Wireless Tools: v27
Wi-Fi Card: Gemtek Prism II based CF card ( hostap_cs reports firmware
as -- NIC: id=0x801b v1.0.0, PRI: id=0x15 v1.1.0, STA: id=0x1f v1.4.9 )
I currently have things set up so that the PCMCIA sub-system loads the
drivers. I've confirmed that hostap_cs, hostap, and hostap_crypt_wep
are all loaded.
I'm following the instructions for Manual Roaming from the HostAP README:
prism2_param wlan0 host_roaming 2
iwconfig wlan0 mode managed
iwconfig wlan0 essid any
iwlist wlan0 scan ( the results from this look OK )
iwlist wlan0 key <WEP key>
iwlist wlan0 essid Pepper
iwlist wlan0 ap <AP MAC>
My problem is that although it looks like I've associated with our AP,
the Bitrate always shows up as 2Mbps. I also see a constantly
incrementing Rx invalid crypt, Tx excessive retries, and Invalid misc
counters when I run 'iwconfig wlan0'.
I also notice that the signal level reported for the AP is very low
(-230 dBm ) when I run 'iwconfig wlan0'. This differs drastically from
the report from 'iwlist wlan0 scan', which reports a signal strength of
-56 dBm from the AP I'm trying to connect to.
When I run 'dmesg', the last two messages are:
wifi0: LinkStatus=1 (Connected)
wifi0: LinkStatus: BSSID: 00:02:2d:40:44:85 ( which is correct for our AP ).
We had been running a Symbol Spectrum24 card w/the Orinoco driver that
worked great, however we have a new requirement to support WPA, thus
I've been working for the past week of so to try and get HostAP working
on the Pepper Pad.
Any help/advice would be much appreciated.
