No wifi adapter found [dell precision 5530 & ubuntu]












2















On my laptop I have trouble with wireless networking since I installed linux. Sometimes when I start the laptop (1 of 3 times) my wireless card doesn't work. Wifi option is missing when I click on toolbar, and in settings in wifi and bluetooth section I got the error:




No adapter found




I also tried checking it with the command sudo lshw -C network
and there is no information about that wireless interface. When I turn off (restart doesn't cut it) and then on, everything works again. When I run the lshw command again, I can see this:

I also tried updating the bios firmware to the newest version, but it doesn't work.



Edit: I added output from dmesg command after startup when wifi didn't work

Edit:
I can't boot system with working wifi anymore but I found this in output of dmesg command:

  • This looks like some failure to detect the hardware. Please look through dmesg after boot in one of those cases when Wifi doesn't work, possibly you can see errors.

Partial answer:



Your wireless adapter sits on PCI bus 3b. According to dmesg,



[    0.338888] pci 0000:00:1c.0: PCI bridge to [bus 3b]


this bus is behind PCI bridge 0:1c.0. There are four error messages regarding four different PCI bridges:



[    0.888395] dpc 0000:00:1b.0:pcie010: DPC error containment capabilities: Int Msg #0, RPExt+ PoisonedTLP+ SwTrigger+ RP PIO Log 4, DL_ActiveErr+
[ 0.888407] dpc 0000:00:1c.0:pcie010: DPC error containment capabilities: Int Msg #0, RPExt+ PoisonedTLP+ SwTrigger+ RP PIO Log 4, DL_ActiveErr+
[ 0.888423] dpc 0000:00:1c.4:pcie010: DPC error containment capabilities: Int Msg #0, RPExt+ PoisonedTLP+ SwTrigger+ RP PIO Log 4, DL_ActiveErr+
[ 0.888436] dpc 0000:00:1d.0:pcie010: DPC error containment capabilities: Int Msg #0, RPExt+ PoisonedTLP+ SwTrigger+ RP PIO Log 4, DL_ActiveErr+


so this might be why it can't find the wireless adapter. I don't know what's supposed to be behind those other bridges.



You could compare to a dmesg output from a working boot, see if the error messages are still present.



However, I suspect some kind of hardware problem. This won't be easy to fix.
