-Wiviz, an open source GPL project, allows you to use your WRT to see other networks. Using a dynamic Javascript-based interface it scans for networks and then shows signal strength and effects of antenna adjustment in real time. 
-The second generation [http://devices.natetrue.com/wiviz2/wiviz2.html wiviz2] has recently been released! This version fixes the previous difficulty to accommodate all icons on the screen by continuously moving all detected stations on a trajectory around the receiving station.

-DD-WRT mini and full releases starting from V23SP3 come with Wiviz2 preinstalled! [http://svn.dd-wrt.com:8000/dd-wrt/browser/src/router/wiviz2?rev=5158] 
-Other installable package for example for Wifi enabled PDA are apparently not available yet!</div>

-=Installation of Wiviz (v1)= 
-<div style="text-align: center; margin: 1em 10%; background: #fa8072; border: #8b0000 1px solid;">The latest version of DD-WRT (23 sp2 mini) does not seem work with Wiwiz! There seems to be a change in the web interface to the [[WL]] tool. Please see the relevant discussion on the [[:{{NAMESPACE}} talk:{{PAGENAME}}|talk page]] for further details. Desweitern scheint die Seite im Firefox 2.0.0.1 nicht richtig zu funktionieren !</div> 
-Thanks to Lament who has ported Wiviz to DD-WRT! 
-# Enable jffs2, and clean jffs2 (administration tab -> management in the control interface) 
-# Use [http://www.dd-wrt.com/wiki/index.php/Telnet/SSH_and_the_Command_Line telnet or SSH] (if enabled) to log in as root on the router. 
-#Next type the following commands (in bold). 
-## '''cd /jffs/''' ''This puts us in the jffs directory from root directory'' 
-##'''wget <nowiki>http://lament.rutka.net/wiviz-jffs.tar.gz</nowiki>''' ''This downloads the permanent (ie, stored in jffs file structure) program''  
-##'''tar -xvzf wiviz-jffs.tar.gz''' ''This extracts files''  
-##'''ln -s /jffs/www /tmp/''' ''This makes the symlink. Please note that there are 3 spaces in this line''  
-##*If the symbolic link already exists the command ''' ln -s /jffs/www /tmp/ ''' '' will fail and you will first have to use : ''' rm -r /tmp/www ''' and then ''' ln -s /jffs/www /tmp/ ''' 
- 
-That should allow your browser to see the wiviz page at  
- 
-http://192.168.1.1/user/wiviz/wiviz.html or <nowiki>http://routerip/user/wiviz/wiviz.html</nowiki> 
- 
-Finally clean up by typing 
- 
-'''rm wiviz-jffs.tar.gz''' ''This will remove the downloaded compressed file'' 
- 
- 
-'''USING A SAMBA SHARE INSTEAD OF JFFS''' If you lack the space necessary to install on JFFS (Using a large installation on a WRT54G is the usual reason) you can simulate JFFS using a network share. See [http://wrt-wiki.bsr-clan.de/index.php?title=Jffs#jffs_on_WRT54G jffs on WRT54G]. 
- 
- 
-You will need to create a subdirectory /jffs/etc/ if it doesn't already exist. 
- 
-'''ls /jffs/''' ''List the jffs/ directory to see if etc/ exists.'' 
- 
-If not, then '''mkdir /jffs/etc''' ''Makes the new subdirectory etc/'' 
- 
-'''mkdir /jffs/etc/config''' ''Creates a new subdirectory to /jffs/etc/ of config/'' 
-'''echo "rm -r /tmp/www" > /jffs/etc/config/wi-viz.startup''' ''Creates startup file with first line'' 
-'''echo "ln -s /jffs/www /tmp/" >> /jffs/etc/config/wi-viz.startup''' ''Appends second line'' 
-'''chmod 700 /jffs/etc/config/wi-viz.startup''' ''Sets file permissions'' 
- 
-<div style="margin: 1em 10%; border: 1px solid #dfdfdf; background-color:#FFE0E0"> 
- 
-In order to get around not being able to change to channel hopping, you can manually create a wiviz config file. 
- 
-'''echo "channelsel=hop&hopseq=1,6,11" > /tmp/wiviz-cfg''' 
- 
-channelsel = Either the word "hop" or the channel number to monitor. The default is to monitor the channel already in use by the card. 
-hopseq = A comma seperated list of channels to hop through in the order of your choice. 
- 
-'''Note:''' ''The wiviz page only displays output - the input settings do not function with DD-WRT.''<br> 
-'''Note:''' ''Channel hopping does NOT work when in AP mode.'' 
-</div> 
- 
-==Wishlist== 
-* Integrate Wiviz by means of links into the routers HTTP system 
-* Graphical signal strength and noise plot function 
-* List stations mode with their signal strength graph on the side (to allow to identifiy directions when scanning using directional antennae) 
-* Automate antenna comparison by using the firmware antenna selector function 
-* IPs be extracted from the packets? 
- 
-==Minor GUI Fix== 
- 
-* Network icons drift out of the screen and everything shifts out of sight: 
--> Solution: Replace the declump function in wiviz.js Java Script with this:  
- function declump() { 
- var c = 0; 
- var top = 150,bottom = -350,left = 550,right = -550; 
- for (i = 0; i < hosts.length; i++) { 
- for (j = 0; j < hosts.length; j++) { 
- if (i == j) continue; 
- e1 = document.getElementById(hosts[i].mnem); 
- e2 = document.getElementById(hosts[j].mnem); 
- if (!e1 || !e2) continue; 
- x1 = parseInt(e1.style.left); 
- x2 = parseInt(e2.style.left); 
- y1 = parseInt(e1.style.top); 
- y2 = parseInt(e2.style.top); 
- ox = x2; 
- oy = y2; 
- if (x2 > left) x2 = left; 
- if (x2 < right) x2 = right; 
- if (y2 > top) y2 = top; 
- if (y2 < bottom) y2 = bottom; 
- dist = Math.sqrt(Math.pow((x1-x2), 2) + Math.pow((y1-y2), 2)); 
- if (dist == 0) { 
- x2 += Math.random() * 5; 
- y2 += Math.random() * 5; 
- dist = 10; 
- } 
- if (dist < 100) { 
- cx = (x1-x2) * 5 / (dist / 3); 
- cy = (y1-y2) * 5 / (dist / 3); 
- x2 -= cx; 
- y2 -= cy; 
- } 
- if (hosts[j].apmnem == hosts[i].mnem 
- || hosts[i].apmnem == hosts[j].mnem) { 
- if (dist > 150) { 
- cx = (x1-x2) * 5 / (dist / 3); 
- cy = (y1-y2) * 5 / (dist / 3); 
- x2 += cx; 
- y2 += cy; 
- } 
- } 
- if (Math.abs(ox-x2) > 2 || Math.abs(oy-y2) > 2) { 
- e2.style.left = parseInt(x2); 
- e2.style.top = parseInt(y2); 
- c++; 
- } 
- } 
- } 
- 
-=Wiviz under DD-WRT v24 final= 
-Status -> Wireless -> Wiviz Survey button 
- 
-'''Windows:'''<br> 
-Firefox 3.0.1 - 3 on Windows properly displays the Wiviz layout. 
- 
-'''Linux:'''<br> 
-''However'', Firefox 3.0.1 - 3 on Linux do not properly display the layout (freezing behavior).<br> 
-Other Mozilla-based browsers do display the layout properly: SeaMonkey, Galeon, Epiphany. 
- 
-Konqueror does properly interpret the Wiviz layout and other portions of the whole WebGUI. 
- 
-=Wiviz under DD-WRT V24 SP1= 
- 
-You can find Wiviz under Status -> Wireless -> Wiviz survey. 
-Alternative you can go to http://192.168.1.1/Wiviz_Survey.asp 
- 
-'''*Note*''': Only Internet Explorer shows wiviz correctly 
-(Tested with: Internet Explorer 8 Beta 1, Firefox 3.0.1 (fail) and Opera 9.52 (fail))
