Hi,
I had a perfectly working Dell system running Windows Vista and using
version 5.60.188.1 of the Broadcom windows driver (distributed by
Dell) for what Windows calls the "Dell Wireless 1397 WLAN Mini-Card",
which is actually 14e4:4315.
I booted Parted Magic 4.9 from a USB flash drive, which uses the
2.6.32 linux kernel.
I started up networking in Parted Magic and asked it to configure the
wireless driver.
At first it found my normal SSID and I asked it to try to connect, but
it failed. I thought this was just a transient issue specific to
Parted Magic and/or linux.
So I booted bank into Vista, only to see that although Vista reports
everything as being fine with the card, no wireless networks are ever
detected. I have verified that the wireless networks that I expect
indeed exist and are in range (the machine has not moved).
Is it possible that the b43 driver somehow corrupted the firmware/ROM
of my card such that it does not function correctly? Can I fix this?
There is a DMA error (also shown below in context): b43-phy0 ERROR:
Fatal DMA error: 0x00000400, 0x00000000, 0x00000000, 0x00000000,
0x00000000, 0x00000000
Please help
I booted back into Parted Magic and got this info from uname, dmesg, and lspci:
