Where should I send my patch for a new feature/bug fix?

Please send your patch to the mailing list.

How do I use WiFi Radar with WPA?

Try the WPA Mini-HOWTO.

How do I use WiFi Radar with WEP?

Under a profile's WiFi Options, set Security to open and enter a Key.

What does "unknown/bug" under Mode mean, instead of "master"?

I believe this comes from iwconfig not interpreting the mode correctly. Since, WR uses a screenscrape from iwconfig for this info, it just passes along the bad info.

Does Wifi Radar support the 802.11N protocol?

All protocols are reported as "g" by Wifi Radar (the "g" status is a lie). But, since WiFi Radar does not care about the protocol, yes it will connect with whatever protocol your card and AP support.

I forgot my WiFi password, how do I re-create it with WiFi Radar?

Sorry, WiFi Radar cannot help with this problem.

What is the script I can use to automatically connect to my network?

This is not a good place to answer a question which needs such a detailed answer. I recommend subscribing to the mailing list and asking your question there. Please also provide a lot more information (e.g. OS, distribution, etc.) in your mailing list question.

Should the network cable be unplugged when trying to configure WiFi Radar?

The network cable is irrelevant as WR is only looking for wireless cards.

Where is the options menu?

There are no menus. Program-wide options can be changed by clicking the Preferences button. Access Point (AP) settings can be changed by selecting the AP, then clicking the Configure button.

How can I use WiFi Radar to connect my computer to a WiFi network using command line tools?

I already know how to configure a wpa-supplicant file etc. But I am trying to find a tool that does all of these automatically. I want to simply give the SSID and the password as a string and the tool should get whether the security is WEP or WPA and connect me to the network automatically.

WiFi Radar automates the calling of command line tools, but not the configuration for each network. You still need to manually edit the wpa-supplicant file for WPA networks. WEP and open networks should be mostly usable as you want (i.e. SSID and password). WR fits somewhere between cli tools and wicd/NetworkManager as far as automation.

Can this app help me to automatically login and logout from the system using my smartphone?

I have a notebook with Linux Mint (with Cinnamon). And I want to activate screensaver on the notebook when my smartphone (with Android) is moving away and deactivate screensaver when my smartphone is near the notebook.

Short answer: no, WiFi Radar cannot do that. Long answer: WiFi Radar helps a Linux computer start and stop a WiFi networking connection to a wireless router. It sounds like you want some type of proximity detector. Maybe NFC would offer what you are seeking?

How do I use WiFi Radar with pam authentication in gnome?

Flipp Bunts contributed directions now enshrined in a HOWTO.

Why am I seeing error...

"wlan0 Interface doesn't support scanning : Device or resource busy"

This is probably a conflict with another network manager like wicd, KNetworkManager, or NetworkManager. Both WR and this other program might be trying to access the wireless card for scanning at the same time. I can duplicate this error by running WR and trying ''iwlist wlan2 scan'' on the command line at the same time.

SyntaxError: invalid syntax

I recently updated to Ubuntu 9.10 and Wifi-Radar will not open from the Applications menu or from an added desktop icon. The installed version is 2.0.s05-1. I've tried to both reinstall and remove/install again without successand I ran the command below from the terminal and received the 'invalid syntax' description shown. I would appreciate any further suggestions that might correct this issue. -- Dave david@ubuntu:~$ sudo wifi-radar Traceback (most recent call last): File "/usr/sbin/wifi-radar", line 2915, in confFile.read() File "/usr/sbin/wifi-radar", line 2798, in read self.auto_profile_order = eval(self.get_opt('DEFAULT.auto_profile_order')) File "", line 1 Siena Hotel,Proximity,omni,wdi-duke-wifi,OldEdwardsInn, ... ^ SyntaxError: invalid syntax david@ubuntu:~$

It looks like you are seeing Ubuntu bug 414399. Rename your WR config file at /etc/wifi-radar.conf or /etc/wifi-radar/wifi-radar.conf and start WR, again.
