DWL-520 just dies for no reason
 
I have a DWL-520 and I've yet to get more then 30 hours (often under 5) before it just stops talking to the router. The only way to get them talking again is to reboot the PC. has anybody had this problem? I saw something about a time out error once........forget where, maybe dmesg. Can you restart just the PCI card? Is it a bug?

What driver are you using? what is the make and model of router?

Are you using DHCP or static IP address?

Are there any other computers on your network?

Do you have a PPPoe connection to your ISP?

Are there any commands that you run to have to bring up the card in working order?

Anything in /var/log/messages or any error messages or other strangeness?

You can try ifdown and ifup on the interface.

Also try
/etc/init.d/network stop
/etc/init.d/network start

to restart the network.

Hello
The router is a PCI D-link air DWL-520 not sure the revision, but it's not new. It ID's the Prism chips.
Mar 9 19:46:59 localhost kernel: prism2pci_init: prism2_pci.o: 0.2.1-pre19 Loaded
Mar 9 19:46:59 localhost kernel: prism2pci_init: dev_info is: prism2_pci
Mar 9 19:46:59 localhost kernel: PCI: Enabling device 00:0d.0 (0114 -> 0116)
Mar 9 19:46:59 localhost kernel: A Prism2.5 PCI device found, phymem:0xf4009000, irq:10, mem:0xd292a000

To tell the truth I'm not sure about DHCP.

The card comes up on boot so I never tried ifup/down.

I've tried /etc/init.d/network restart to no avail but will try the other.

/var/log/messages says
Mar 9 19:44:24 localhost kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Mar 9 19:44:24 localhost kernel: hfa384x_tx_timeout: Implement me.
Mar 9 19:44:29 localhost kernel: NETDEV WATCHDOG: wlan0: transmit timed out
Mar 9 19:44:29 localhost kernel: hfa384x_tx_timeout: Implement me.
over and over and over
Thanks a ton.

I read somewhere that this was possibly a interrupt issue in the driver.

Possibly try loading the driver with the parameter irq_mode=1

Do you have any laptop devices (PCMCIA) on the computer?

Do you know where you downloaded the driver from?

Sorry I don't know the exact problem now.

ka9qlq 03-10-2004 08:20 AM

Well that's more then I though of. I realy appeciate your help.

I don't have any PCMCIA stuff, it's a desktop.

A friend found the driver, I'll ask him.

I know this sounds dumb but how would you load the driver with the parameter irq_mode=1? fstab maybe?

Thanks

Ok I found this
This appears to be a problem with the kernel APIC drivers related to the
on-board chipset. The solution is to add the following to lilo:

append=noapic

This will allow the kernel to communicate properly with the network
adaptor.

here
http://www.lunar-linux.org/pipermail...ry/000088.html
I tried that and we'll see. Here's my lilo incase I did it wrong.

I unfortunately don't have any suggestions with for your problem with keeping your DWL 520 card working. Although I am very interested on how you were able to get it working. I have been struggling for a week now. I am new to Linux and I am not sure what driver I need to use or how to install it.

Linux does see that the pci card is there when I run lspci -vv I recieve the following information:

00:0f.0 Ethernet controller: Realtex Semiconductor Co., Ltd.: Unknown device 8180 (rev 20)
Subsystem: D-Link System Inc: Unknown device 3303
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Steping- SERR- FastB2B-

....etc......

But when I try to install the card I am getting a response that a network card is not installed on the system.

Is this anything you can help with?

I apologize for my ignorance with Linux.

ka9qlq 03-23-2004 03:39 PM

Well your card must have the Realtek 8180 chip set my card has a Prisum 2.5 chip set. The Linux drivers for the older chip sets have been prety well debugged, but the drivers for the new chip sets [like the 8180] stil have BUGGS! That's why I sold my 8180 card and got an older DWL-520 card.

I think the card flipping out is because the PC is a 400 mhz and when I load the CPU down it can't handle all the i/o. Firebird seems to make it die but it doesn't under Konqueror.

Realtek 8180
 
Yeah my card is the 8180 chipset....do you have any suggestions on how to get it to work? I am pulling my hair out on this one.

--Thanks

ka9qlq 03-24-2004 03:38 PM

Well I never got mine to work, that's why I got an older card with a differnt chip set. Find a Windows user and sell it to them cause it works under Windows.
