Cara mengatasi wifi wireless lan card yang tidak bisa terdeteksi di linux

Post by agoenk on Sat Feb 20, 2016 6:50 pm

ketika kita menginstal linux misalkan linux mint, terkadang wireless card kita tidak terdeteksi. dibawah ini adalah salah satu cara agar wireless card kita bisa terdeteksi di linux mint

pertama kita perlu mengetahui jenis wlan kita dengan cara masuk terminal kemudian masuk super user dan ketikan lspci,

jenis wlan Broadcom Corporation BCM43142 caranya adalah :

I just installed LMDE 201403, and as expected, I had problems with my wireless. I had installed debian (stable) in the same computer, a Lenovo Edge E431, and the wireless didn't work, but I managed to fix the problem following this blog: ... on-debian/
So, I followed the same steps after installing LMDE, but now it didn't work. Now I show you what I did:
First of all, lspci

Code: Select all
   # lspci | grep Network
   04:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

following the instructions of the blog, I ran

Code: Select all
   apt-get install linux-headers-generic build-essential dkms broadcom-sta-modules

In debian stable I had no error, but now the linux-headers-generic package is missing:

Code: Select all
   Package linux-headers-generic is not available, but is referred to by another package.
   This may mean that the package is missing, has been obsoleted, or
   is only available from another source

   E: Package 'linux-headers-generic' has no installation candidate

I skipped that part and installed the other packages:

Code: Select all
   #apt-get install build-essential dkms broadcom-sta-modules
   Reading package lists... Done
   Building dependency tree      
   Reading state information... Done
   Note, selecting 'broadcom-sta-dkms' instead of 'broadcom-sta-modules'
   build-essential is already the newest version.
   dkms is already the newest version.
   The following NEW packages will be installed:
   0 upgraded, 1 newly installed, 0 to remove and 18 not upgraded.

   After this operation, 9,965 kB of additional disk space will be used.

   DKMS: install completed.

Finally I installed the .deb:

   (Reading database ... 146537 files and directories currently installed.)

   Consult /var/lib/dkms/wireless-bcm43142/ for more information.

Even having an error i kept going, so i ran the modprobe wl, but it didn't do anything. I searched ways to fix the "Bad return status for module build on kernel: 3.11-2-amd64 (x86_64)" error, but I couldn't find anything. I also tried to solve the linux headers error, but I don't know which headers should be installed to fix this. There's another solution to my problem in thinkwiki: ... _Edge_E135
but it implies using an ubuntu package, and i'm not sure of using this.

If anyone is asking about the make.log, here it is:

Code: Select all
   DKMS make.log for wireless-bcm43142- for kernel 3.11-2-amd64 (x86_64)

atau bisa secara lebi lengkap dilihat di

untuk wifi RTL8723BE

Buka terminal linux mint.
Masuk ke SU dan ketikkan “lspci“. “lspci” berguna untuk melihat tipe perangkat-perangkat yang terkoneksi pada soket PCI komputer.
lihat tipe wireless network adapter nya, apabila perangkat memiliki wifi adapter tipe RTL8723BE apabila tipe sesuai silahkan anda ikuti langkah selanjutnya. jika tidak maka cerita anda sampai disini.
kemudian ketikkan “sudo apt-get install linux-headers-generic build-essential git” pada terminal, kode tersebut berfungsi untuk menambahkan header repository github directory pada linux mint yang terinstall.
download driver dari github directory dengan cara mengetikkan kode berikut “git clone” pelalui terminal.
pindah ke directory dimana driver di download dengan mengetikkan “cd rtl8723be” pada terminal.
Tahap ke tujuh ini yang sempat buat penulis puyeng, driver tidak dapat di install dengan error bahwa driver sudah tidak cocok lagi dengan os yang teristall. maka yang penulis lakukan adalah dengan cara merubah directory dengan data yang lebih lawas dengan cara mengetikkan “git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9” pada terminal.
tahap terakhir adalah melakukan penginstallan dengan cara mengetikkan kode “make“,”sudo make” dan “sudo modprobe rtl8723be” secara berurutan di terminal.
Driver wifi RTL8723BE telah terinstall dan siap digunakan
