Hi guys, I'm trying to set up an ad hoc connection on a verdex+netwifimicroSD stack (the wpa-psk I had set up just stopped working for some reason), but I haven't really achieved much. My /etc/network/interfaces file looks like this: #Configure Loopback auto lo iface lo inet loopback iface usb0 inet dhcp auto eth0 iface eth0 inet dhcp iface eth1 inet dhcp iface wlan0 inet dhcp auto mwlan0 iface mwlan0 inet static pre-up /sbin/iwconfig $IFACE mode ad-hoc essid "gums" txpower 100mW rate 11M address 20.20.10.0 netmask 255.255.255.0 But I get nothing after booting it up. During boot I do get these lines: Entering cf_attach() pcmcia: request for exclusive IRQ could not be fulfilled. pcmcia: the driver needs updating to supported shared IRQ lines. BasePort1=0xc4880000, AssignedIRQ=128 After calling wlan_add_card function After register driver I've seen those IRQ messages browsing through the mailing list archives, but no solution, or even if they're actually bad. Ifconfig and iwconfig give me this: # ifconfig eth0 Link encap:Ethernet HWaddr 02:00:00:00:22:90 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:131 Base address:0x2000 DMA chan:ff lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) mwlan0 Link encap:Ethernet HWaddr 00:0B:6B:0D:21:FE inet addr:20.20.1.0 Bcast:0.0.0.0 Mask:255.255.255.0 inet6 addr: fe80::20b:6bff:fe0d:21fe/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:19 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:5001 (4.8 KiB) Interrupt:128 # iwconfig lo no wireless extensions. eth0 no wireless extensions. mwlan0 MRVL-CF8385 ESSID:"gums" Nickname:"" Mode:Ad-Hoc Frequency:2.437 GHz Cell: 02:29:19:86:A3:85 Bit Rate=11 Mb/s Tx-Power=18 dBm Retry limit:8 RTS thr=2347 B Fragment thr=2346 B Encryption key:off Power Management:off Link Quality:0/10 Signal level:-2 dBm Noise level:-2 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:3892 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Any suggestions?

I had to uninstall the madwifi package that comes bundled with Ubuntu (I was only getting 4/100 signal strength) and get ndiswrapper configured with the Windows drivers, and after some struggling I got it to connect to the gumstix (and only to the gumstix, if I try to connect to my WPA network the laptop freezes). -- View this message in context: http://www.nabble.com/Ad-hoc-wifi-on-verdex-tp16763563p16787258.html Sent from the Gumstix mailing list archive at Nabble.com. |

20.20.10.0 is not a host address is your netmask is 255.255.255.0. In fact, this the address of the network. try to change IP adress, like 20.20.10.5 for example Nicolas On Friday 18 April 2008 12:35:46 Dante Sanchez wrote: > Hi guys, > > I'm trying to set up an ad hoc connection on a verdex+netwifimicroSD stack > (the wpa-psk I had set up just stopped working for some reason), but I > haven't really achieved much.

I just came up with the > 20.20.1.0 for no reason. With a netmask of 255.255.255.0 or /24 in alternate terminology, you theoretically have 256 individual IP adresses. The last address of .255 is called the broadcast address and has special meaning to devices on the network. The first address of .0 is called the network address and is most often used when specifying routing. This leaves a valid range of .1 to .254 for your individual hosts. Routers will most often be set to .1 or .254, so the safe range would be .2 to .253. If you want your device to talk to the outside world, then you will need to use an IP address that is in the range used by your router/gateway device. To find this information, log into your gateway device and look at the configuration. This is a very simple explanation and misses out on some details. For most people, DHCP is the easiest way to get running on a network. Since you are not familiar with TCP/IP networks and terminology, I suggest you work on getting your gumstix dhcp working as it will make your life much easier. -- Keith |

It is really frustrating. Especially after trying hard to get WEP working on ubuntu 6.06 (it is probably my fault! however, I should admit 7.10 is superior for Wifi configuraion and networking in general). I then fail on gumstix. Even when I save /etc/network/interfaces using tweener and reboot I see the file unchanged (kernel 1559). it worked (i.e. file saved) when I unplugged the power while already logged onto console!? I read through this thread and several others on setting up ad-hoc mode on gumstix. i could not make it work on gumstix. can someone please provide example interfaces file here again fr ad-hoc mode? Note: I have mwlan0 working in a lab setting with static IP assignment and a default gateway. i wanted to set several gumstixs for the same ad-hoc group. it is ok to have one of the node act as default gateway but no physical router is assumed in the propagation range. Any pointers are greatly appreciated!
