I bought a wifi adapter for my raspberry pi, but I have problems making work on raspberry pi.

I tested it on a PC running Ubuntu. It has exactly the same behavior, as follows:

  1. When inserted, lsusb shows it.

    $ lsusb                                                                                                                                                                     
Bus 001 Device 003: ID 0bda:818b Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 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 002 Device 002: ID 04d9:1603 Holtek Semiconductor, Inc. Keyboard
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    The first one -- Realtek Semiconductor Corp. -- is the wifi adapter.

  2. ifconfig doesn't list it.

    $ ifconfig

I expected to see a wlan0, but it doesn't appear. I tried lot of ways to make it work, but still without success.

Would like to hear how can I solve the problem. The goal should be to connect to a router with username and password and get internet.

Where should I start? Maybe the drivers is the problem?

  • You can try [this solution](https://sites.google.com/site/easylinuxtipsproject/reserve-7#TOC-Realtek-RTL8192EU-chipset-0bda:818b-) – Pilot6 Aug 11 '15 at 17:00
  • @Pilot6 Thanks, I'm trying and give feedback then – Ionică Bizău Aug 11 '15 at 17:03
  • @Pilot6 The compiling failed. [Here](https://gist.githubusercontent.com/IonicaBizau/d31cc772fbd6faee5cd9/raw/c478c2abdbefa0f64874ef1590aa44ba2fa87a8a/gistfile1.txt) is some relevant output. – Ionică Bizău Aug 11 '15 at 17:13
  • The first error says `recipe for target '/.../install_folder/driver/rtl8192EU_linux_v4.2.2_7585.2‌​0130524/os_dep/linux/usb_intf.o' failed` – Ionică Bizău Aug 11 '15 at 17:17
  • I can't help at the moment. I build lots of realtek drivers to debs, but did not look into this one yet. – Pilot6 Aug 11 '15 at 17:18

  • @Pilot6 Would give you a bounty of 100 rep points if you do it. :D – Ionică Bizău Aug 11 '15 at 17:19
  • I added another solution, You can give a bounty there, if it works. And I will build a dkms package to be able to upgrade kernels. – Pilot6 Aug 11 '15 at 17:20
  • @Pilot6 Umm... I'm getting `Error! Bad return status for module build on kernel` when I `dpkg -i that.deb`... – Ionică Bizău Aug 11 '15 at 17:25
  • Well no dice then yet. – Pilot6 Aug 11 '15 at 17:27
  • @Pilot6 It didn't really fail. Now `wlan0` appears in `ifconfig` output but it doesn't have an address. [Here is the `ifconfig` output](http://chat.stackexchange.com/transcript/message/23362879#23362879). – Ionică Bizău Aug 11 '15 at 18:09

  • you could try this http://askubuntu.com/a/863433/633710 (Works fine until kernel 4.8) – Gi_44 Dec 22 '16 at 10:11
  • Used this driver in Mint 19.3 , works but at a snails pace . https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+build/10629089 – Brendan J Walker Aug 28 '19 at 20:36
