Ik ben in bezit van 2 powerbooks met een PCMCIA kaart Cisco Aeronet 350 die ik niet draadloos met elkaar kan laten communiceren zonder een Access point (dus in ad hoc-mode).
In computer to accespoint-mode kunnen beide computers wel verbinding maken met een access point en zo met elkaar communiceren.
In de Utility software waar je de kaart mee kan configureren, kunnen de beide kaarten in ad hoc-mode elkaar wel 'zien'. Dat wil zeggen dat 'signal strength' en 'signal quality' vrijwel op 100 % staan als beide op hetzelfde ad hoc-netwerk zijn aangesloten (zelfde naam) en hetzelfde kanaal.
De TCP/IP instellingen van de kaart heb ik hetzelfde gemaakt als bij een verbinding tussen de twee computers middels een UTP-crosscable (deze laatste verbinding is wel succesvol):
Manually, IP Address: 192.168.1.20 / 192.168.1.21, Subnet Mask: 255.255.255.0, overige velden leeg.
Apply Now, Restart, maakt allemaal niets uit: De Finder kan geen verbinding zien tussen de powerbooks.
Dagen lang allerlei varianten geprobeerd en internet afgezocht en alle FAQ's en handleidingen van de Cisco-site bekeken. Niets over te vinden wat hier het probleem kan zijn.

Iemand een tip?

Systemen: G3-series II-PDQ-300 MHz en G3-Firewire-Pismo-400 MHz
Beide voorzien van MAC OS 10.3.8 en beide voorzien van een PCMCIA-kaart van Cisco:
Aeronet AIR-PCM350 SERIES met firmware 4.25.30 en Aeronet Client Utility versie 1.0.2

LED's op pcmcia kaart:
Status (groen) brandt continu
Activity (amber) knippert zeer snel

Starting test.

TEST 1:
The first step is to check your radio.

Your radio is working properly.

TEST 2:
The second step is to check your client adapter's association with the access point.

Your client adapter is associated to:
   Access Point :
   Network name : The TEST

TEST 3:
The third step is to check your network settings.

Your client adapter is configured correctly.
Your IP address is 192.168.1.20

TEST 4:
The fourth step is to check your connection to the access point.

Unable to get the IP address of your access point. You may be using a non Cisco access point. Skipping this test.

''
   The signal strength was 100 percent.

WARNING: Your ip address (192.168.1.20) is not on the same subnet (mask ff.ff.ff.00) as the AP (0.0.0.0).
POSSIBLE REPAIR: Check you network setup. Make sure that you have specified the correct AP to which you want to associate. Make sure that your IP address is correct. Make sure that you have positioned your APs so that only there is only one AP to which your radio can associated. If multiple APs are necessary, make sure the APs are on the same subnet or have different network names (make sure that you only specify one of those network names for your radio).
Your client adapter is working properly.

Testing completed.
