I'm very happy that, there are people try to help me with my problem here. Ok, let me give overall overview of my project.
My task is to develop PMIPv6 test-bed. I used OpenAirInterface PMIPv6 software. Here is the architecture of my PMIPv6 test-bed : PMIPv6_schema_example_1LMA_2MRs.jpg
Right now, let focus to my problem, where it included the Access Point (in figure attach is SSID : MAG1) which i mention the essid named is 'mimos1'. The static IP is 192.168.13.100 and the remote server for this IP is MAG1 which connected to the AP via eth1 with IP 192.168.13.1. The AP is in masquerade mode. AP that i used is Cisco Aironet 1200 Series.
Scenario 1 : I used MN device with Window 7 system and try to connect to the AP (mimos1). It connected as well as it get IPv6 address from this AP which forwarded from MAG1. The IPv6 address of my MN that used window 7 system is 2001:100:6:5000:214:6cff:fe53:180a (as shows in the figure as well). So i can assume that, there is no problem with the AP right?? Am i right?
Scenario 2 : I used MN device with ubuntu 10.04 LTS and try to connect to the AP (mimos1) exactly same with scenario 1. I scan access point available and next post :
After I scan, I can see that there is 'mimos1'. Oh yeah. When I check in this scanning result, i can see 2 cell is detected 'mimos1' in with different channel and address. When I finish scan, I just click my network manager icon and click for 'mimos1' (here, at network manager icon, i see only one 'mimos1' listed). So when i connect, wlan0 will be loading for awhile to try to be connected, but than, it drop the connection.
So, In short, I only have problem connecting my ubuntu laptop with my AP :-(
