I recently installed suse 11.4 x64 onto my hp tx2000 tablet. everything has been working great including the wifi card. It’s a broadcom 4328 a/b/g/n/bluetooth card and it was using the broadcom-wl driver. Earlier today i plugged in an usb wifi adapter to test whether it worked on suse plug and play. Well after plugging in and using this wireless adapter, my internal wifi card is no longer visible to the system. I’ve tried lspci and its not displayed. I booted into a different suse install and it wont work there. My bios does not seem to have a disable feature and the killswitch is in the correct position. The bluetooth is working but the wifi is not. In lspci i used to see “hp integrated (wireless+bluetooth)” and “broadcom 4328…” but now only the former.

I know you rebooted since plugging in the USB device, but have you powered off?
It is obvious that your bus adapters are messed up. It is surprising that a USB
device could do this - it has not happened to me. If a cold reboot doesn’t
restore it, please post the output of the ‘/sbin/lspci -nn’ command, place the
full output of dmesg in pastebin.opensuse.org, and post the link here.
I’ve rebooted several times now and have powered off the machine, I even removed the battery for a while. I am very surprised with how this occurred as well.
There are two things in your dmesg output that do not look right. The first is
3.579081] usb 2-7: New USB device found, idVendor=03f0, idProduct=171d
3.579085] usb 2-7: New USB device strings: Mfr=1, Product=2, SerialNumber=0
3.579088] usb 2-7: Product: HP Integrated Module
3.579090] usb 2-7: Manufacturer: Broadcom Corp
What Broadcom device is connected to your USB system? What does lsusb show? I
suppose this could be the Bluetooth device.
The second thing is
8.994198] forcedeth: Reverse Engineered nForce ethernet driver. Version 0.64.
8.994510] ACPI: PCI Interrupt Link [LMAC] enabled at IRQ 20
8.994527] forcedeth 0000:00:14.0: PCI INT A -> Link[LMAC] -> GSI 20 (level,
high) -> IRQ 20
8.994532] forcedeth 0000:00:14.0: setting latency timer to 64
8.994539] forcedeth 0000:00:14.0: PCI: Disallowing DAC for device
8.994541] forcedeth 0000:00:14.0: 64-bit DMA failed, using 32-bit addressing
8.994543] forcedeth 0000:00:14.0: PCI: Disallowing DAC for device
8.994545] forcedeth 0000:00:14.0: 64-bit DMA (consistent) failed, using
32-bit ring buffers
I am surprised that the Ethernet controller is forced to 32-bit operation. I
suppose that may be right if you have a 32-bit OS.
What happens if you go into the BIOS and reset it to the Factory Default settings?

I just did a reset in BIOS and still the same issues.

The only other thing to try is opening the case (if possible) and reseating the
wifi card. On most laptops, there is a “trap door” on the bottom. I don’t know
about the tablet.
If that doesn’t work, I think we have to conclude that your motherboard is
broken. Either that USB device you plugged in was defective and damaged
something (unlikely), or the fault just happened at the same time (bad karma).
Ok so I’ve pulled out the mini pci express wifi adapter from inside the tablet. i booted without and then with it again, still nothing. I do have MS Vista still installed, tried to go there…still nothing. I have found all over the net that people have problems with this laptop and heat issues killing the wifi and gpu. Supposedly it IS a motherboard issue. I guess I am one of the fortunate ones to get 4+ years with this device and no problems, until now.
I’ll update if anything else comes up, Thanks so much to all here!
