 Posted: Sat Jan 05, 2013 11:11 am Post subject: Not working : Belkin Wireless USB F7D2102 / rtl8192cu |
 |
|
Hello,
I've been offered a USB wireless interface. Unfortunately I'm unable to make it work out.
Before I would test the ndiswrapper option, I would appreciate some advices.
I use the kernel gentoo-sources-3.5.7
| Code: |
localhost linux # uname -r
3.5.7-gentoo
|
wpa_supplicant and linux-firmware are emerged.
Result of lsusb is:
| Code: |
localhost linux # lsusb
Bus 001 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU]
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
|
rtl8192cu - as described by the output of lsusb - is compiled as a kernel module and loaded :
| Code: |
localhost linux # pwd -P
/usr/src/linux-3.5.7-gentoo
localhost linux # grep 8192 .config
# CONFIG_RTL8192CE is not set
# CONFIG_RTL8192SE is not set
# CONFIG_RTL8192DE is not set
CONFIG_RTL8192CU=m
CONFIG_RTL8192C_COMMON=m
localhost linux # lsmod
Module Size Used by
rtl8192cu 82195 0
rtl8192c_common 49008 1 rtl8192cu
rtlwifi 82684 1 rtl8192cu
3c59x 29257 0
|
the dmesg log shows neither warning nor errors for keywords 8192 :
| Code: |

I can see the interface after commanding ifconfig -a
| Code: |
localhost linux # ifconfig -a

No IP address while I described it as a static in /etc/conf.d/net
| Code: |

config_eth0=( "192.168.1.11/24" )
routes_eth0=( "default via 192.168.1.1" )
|
The only clue is : Unsupported driver rtl8192cu when I try to start the interface:

|
I sincerely would like to use the kernel module to access to the internet through the USB interface.
Have you any ideas how I could handle this "Unsupported driver" error ?
Should I use another driver ?
Please let me know if you need me to paste outputs.
Thank you.

Nicolas_Y,
| Code: | modules="wpa_supplicant"
wpa_supplicant_wlan0="-Drtl8192cu" |
Try -Dext in place of -Drtl8192cu
That driver does work

Is that a typo?
(The default wpa_supplicant driver is
which is a generic wpa_supplicant driver that works with multiple
different wireless chipsets if support for those chipsets is enabled
in the kernel. Works fine here with two different kernel wifi
hardware drivers, zd1211rw and rtl818x.)

Hi, I'm new
My Belkin F7D2101 v1 wi-fi usb adapter (which works very well in Archlinux in the same notebook) do not works at all. I've tryed all the suggestions in this discussion and in this forum, but...noway! ifconfig does not see wlan0!
If you need to see some output, take a look here https://forums.gentoo.org/viewtopic-t-947570.html.
Excuse me if I'm posting here, but I need help, please.
Sorry for my bad english.
Thanks in advance. |

Hal-10000,
You have different hardware to the one discussed here.
| Code: | # lsusb
Bus 001 Device 002: ID 050d:2103 Belkin Components F7D2102 802.11n N300 Micro Wireless Adapter v3000 [Realtek RTL8192CU] |
This thread is for a device with Vendor and Device Ids ID 050d:2103.
Your device is a | Code: | # lsusb
Bus 001 Device 002: ID 050d:845a Belkin Components F7D2101 802.11n Surf & Share Wireless Adapter v1000 [Realtek RTL8192SU] |
They may be the same on the packaging ... they may even share a driver too but you need to check that. You have a ID 050d:845a
You need the r8712u kernel module and probably linux-firmware. I'm using a netbook with a cut down Gentoo just now so I cannot easily check

Neddy, Thank you for the replay.
You say that I need r8712u driver. This is the one I have in Archlinux and it works fine. But in Gentoo kernel I found only RTL8192CU, so I compiled that one as 'module' <M>. I'm not sure, but they seem to be the same thing, because the 'rtl8192cu' becomes 'r8712u' after unzipping.
I've also installed linux-firmware, but nothing to do!
I've tryed to emerge ndiswrapper, but I got a failure.
I really don't know what to do now, except to buy another usb wireless adapter....
Sorry for the double posts  |

For modern drivers, wpa_supplicant_wlan0 should be set to "-Dnl80211" and not "-Dwext".
Also verify thatlists a driver for the device.
Do not use any driver that you downloaded from Realtek. To find out more why it does not work you can run
| Code: | # ifconfig wlan0 up
# iw dev wlan0 scan |
and watch console/dmesg for error messages. |

Hal-10000,
Your driver is in the kernel, its under the help says
| Code: | RealTek RTL8192U Wireless LAN NIC driver ────────────────┐
│ CONFIG_RTL8192U: │
│ │
│ │
│ Symbol: RTL8192U [=n] │
│ Type : tristate │
│ Prompt: RealTek RTL8192U Wireless LAN NIC driver │
│ Defined at drivers/staging/rtl8192u/Kconfig:1 │
│ Depends on: STAGING [=y] && PCI [=y] && WLAN [=y] && USB [=y] && \ │
│ m && <choice> │
│ Location: │
│ -> Device Drivers │
│ -> Staging drivers (STAGING [=y]) │
│ Selects: WIRELESS_EXT [=n] && WEXT_PRIV [=n] && CRYPTO [=y] |
Do not use random code from the web until you have tried the in kernel driver.
Remove ndiswrapper too as you are in danger of having two (or more) drivers for the same piece of hardware.
Its harmless to the hardware but it won't work as the mulitiple drivers try to control the hardware.

This means that the device is not connected.

This means that you don't have emerged iw. |

it's very strange, the usb adapter is connected.... but | Code: | hal-10000 sciacuddi # lsusb -t
/: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M
/: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=uhci_hcd/2p, 12M

/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M
|
I don't know why, because | Code: | hal-10000 sciacuddi # lsusb
Bus 001 Device 003: ID 050d:845a Belkin Components F7D2101 802.11n Surf & Share Wireless Adapter v1000 [Realtek RTL8192SU]
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
|
if the device was not connect, I do not have that output in lsusb, don't you think so?
then I emerged iw and | Code: | hal-10000 sciacuddi # iw dev wlan0 scan
command failed: No such device (-19)

Ah, ok. That's what you get when you hijack other people's threads instead of starting your own.  |

@NeddySeagoon
I was trying to do what you said.
I issue this command: | Code: | # cd /usr/src/linux
make menuconfig |
and then in:
Driver devices --->
Staging drivers --->
I've set <M> at "RealTek RTL8192U Wireless LAN NIC driver"
Then I compiled the kernel, updated the Grub, rebooted.
But it did not work 
(in plus now my touchpad does not work )
I have to notice that in menuconfig, there are other drivers/modules which I set before, such as:
Device drivers --->
Network device support --->
Wireless Lan --->
<M> Realtek RTL8192CE/RTL8188CE Wireless Network Adapter │ │
│ │ <M> Realtek RTL8192SE/RTL8191SE PCIe Wireless Network Adapter │ │
│ │ <M> Realtek RTL8192DE/RTL8188DE PCIe Wireless Network Adapter │ │
│ │ <M> Realtek RTL8192CU/RTL8188CU USB Wireless Network Adapter
I'm asking if I have to delete the <M> in the drivers above...or something else

| As your "ifconfig -a" differs, you two obviously have different problems. So make a new thread. |
