- | The zd1211rw driver has been incorporated into the latest kernels. | + | The ZyDAS zd1211 and zd1211b (//also known as AR5007UG//) chips are one of the most distributed wireless b/g chips in the market. They are also the cheapest, on eBay, you can get one for about 5-6USD shipping included. In the same time, these chips are very stable, with excellent range and sensitivity, |
- | The following links may be helpful | + | The zd1211rw was included in mainline kernel 2.6.18 as a softmac driver, known to be notoriously unstable and heavily crippled in terms aircrack-ng support. Things turned for the better when the zd1211rw was ported as mac80211 |

- | ===== Patching zd1211rw ===== | + | Overall, its a great all-purpose chip to have for wireless auditing and general connectivity. |
- | This section will describe how to patch your driver for injection. There is quite a bit of variation between distributions so this describe the general steps you must take. You will have to tweak the instructions for your specific distribution and kernel version. | + | ====== Patching ====== |

- | At this point, the simplest method | + | **4.** Patching is complete and we are ready to compile our driver, type **make** for the process |
- | If you have problems compiling zd1211rw, you can try: | + | **5.** Barring any errors, next up is installing, **sudo make install** |
- | | + | **6.** Now that the newly compiled driver is installed, we are ready to use it, but before that we have to unload the old driver by typing **sudo |

- | ===== Installing Fedora kernel headers | + | **7.** To load the new driver, just type **sudo modprobe zd1211rw** or simply unplug |
- | These instructions are specific to Fedora. Change | + | **8.** That's it! This concludes |
- | You need these packages already installed: | ||
- | kernel-headers-2.6.20-1.2944.fc6 | ||
- | kernel-devel-2.6.20-1.2944.fc6 | ||
- | Running the command **rpm -qa | grep kernel** will show which kernel packages are installed. | + | # aireplay-ng -9 mon0 |

- | Now download and install | + | As mentioned above, kernels prior to 2.6.25 (2.6.2**4** with compat-wireless) are shipped with the softmac version of the driver which in its best day supports only half the functions, half the time. In other words, |

- | ===== Recompiling Kernel with Loadable Modules ===== | + | |
- | + | ||
- | Some kernels incorporate the functionality built into the kernel. | + | |
- | + | ||
- | These are the settings for menuconfig using 2.6.20-gentoo-r7, | + | |
- | + | ||
- | First, change the appropriate items in menuconfig: | + | |
- | + | ||
- | cd / | + | |
- | + | ||
- | make menuconfig | + | |
- | + | ||
- | | + | |
- | then set | + | |
- | < | + | |
- | < | + | |
- | all other module capable IEEE 80211 items will have automatically set themselves to <M> | + | |
- | + | ||
- | Also check that: | + | |
- | | + | |
- | < | + | |
- | + | ||
- | Exit out and save the config | + | |
- | + | ||
- | Now apply the zd1211 and ieee80211 inject patches and recompile/ | + | |
- | + | ||
- | Apply the zd1211 inject and ieee80211 inject patches as per patch instructions but only do the 4 patch -Np1 commands, in gentoo doing the make commands and copying all the files is unnecessary!! | + | |
- | + | ||
- | After the patches are applied, you can now recompile the kernel and modules with the following commands: | + | |
- | + | ||
- | cd /usr/src | + | |
- | make && make modules modules_install install | + | |
- | + | ||
- | Wait for it to finish and then reboot your system. | + | |
- | + | ||
- | Lastly, test your drivers and the injection patch. | + | |

- | A common problem on new kernels is that the new mac80211 version of the driver gets loaded instead of the older legacy driver covered on this page. If that is the case, then you need to blacklist the modules by editing / | + | |

- | Also ensure that the time stamp on zd1211.ko module matches the date and time you compiled it. Otherwise this may mean you are running the wrong version of the module. | + | |
