Interface doesn't support scanning
by Alain_Reve from LinuxQuestions.org on (#5F8DV)
Hello everybody!
I have no wireless. Wired connection is OK. I'm using an Acer 3100 laptop.
It seems I have a driver for the wireless called "b43-pci-bridge":
lspci -vvnn
06:02.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller [14e4:4318] (rev 02)
Subsystem: AMBIT Microsystem Corp. TravelMate 2410 [1468:0312]
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
Latency: 64
Interrupt: pin A routed to IRQ 22
Region 0: Memory at c0200000 (32-bit, non-prefetchable) [size=8K]
Kernel driver in use: b43-pci-bridge
Kernel modules: ssb, wl
For some reason the wifi can't be scanned :
iwlist scan
enp6s1 Interface doesn't support scanning.
lo Interface doesn't support scanning.
And has no extension, whatever these may be :
iwconfig
enp6s1 no wireless extensions.
lo no wireless extensions.
But it has a controller:
lspci
06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10)
06:02.0 Network controller: Broadcom Inc. and subsidiaries BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)
And it is compatible with the kernel:
iwconfig -v
iwconfig Wireless-Tools version 30
Compatible with Wireless Extension v11 to v22.
Kernel Currently compiled with Wireless Extension v22.
Network-manager and wifi-radar don't see the wifi. But I'm sitting right next to the box!
I've been browsing and typing any relevant command I came across. Nothing seems to help.
I don't know much about all this, usually it functions right after the install. But still, I find it strange to see no wlan0, no eth1, not event an eth0. lo I've seen before but not enp6s1.
Any suggestions welcome
