 |
|
i'm having kernel ...20 and compiled ipw2100 as module and using wpa_supplicant. everything works fine - connection is fine.
but after some time - no matter if there is traffic or not my wireless connection seems to isconnect. then "ifconfig eth1" shows the following:
| Code: | eth1 Link encap:Ethernet HWaddr 00:0C:F1:42:F3:BD
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:35153 errors:0 dropped:0 overruns:0 frame:0

RX bytes:34431548 (32.8 Mb) TX bytes:2620305 (2.4 Mb)
Interrupt:18 Base address:0x8000 Memory:fe8fe000-fe8fefff |
after some time (two minutes or so) the connection just comes back.
my "/var/log/dmesg" says following:
| Code: |

"cat /var/log/dmesg | grep "IRQ 18" gives:
| Code: | ACPI: PCI Interrupt 0000:01:03.1[B] -> GSI 18 (level, low) -> IRQ 18

So there are 4 devices on IRQ 18???
can this be the cause for my disconnections?
any ideas? |

| You can "cat /proc/interrupts" to see what devices are on what IRQs. |

| after serious consideration i think it might be acpi sending my wireless card to sleep for powersaving purposes. but it shouldn't be doing that while there is traffic on the card, right? does anybody know how to tell acpi not to care about a special device? |

i have this problem too... but has not found any solution yet...
are you using WPA? In my case, I connect to 2 APs, depending on where I am. One has WPA only and the other is an open network. Then open network ALWAYS works, even when there is little or no traffic most of the time. The WPA one will just die on me even when there is traffic.
I found another error besides the "firmware restart" message:
| Code: | | ipw2100: exit - failed to send CARD_DISABLE command |
