You can also check your channel...<br>
iwconfig ath0 channel NN<br>
<br>
Where NN is the channel that your wlan is using.. and of course update your module to the last cvs version...<br>

Well, I recommend you using the cvs version as indicated in:<br><br><a href="http://madwifi.sourceforge.net/">http://madwifi.sourceforge.net/</a><br><br>We have assembled few access points for the local wifi network on my
<br>town recently with an Atheros-based board (from Senao) and it works<br>perfectly with the cvs, we had problems with the ebuild and deb<br>version (for gentoo and debian) and solved it using the latest cvs.<br><br>cheers

&gt; &gt;<br>&gt; &gt; Can you post the Quality of the link when you are near the AP, the<br>&gt; &gt; version of the madwifi you are using and which mask for the packages?<br>&gt;<br>&gt; Hi Jordi,<br>&gt;<br>&gt; Sorry for the late response.&nbsp;&nbsp;My madwifi-driver version is 
0.1_pre20050224.<br>&gt;<br>&gt; Far from the access point, link quality is 16/94 or -79dBm.<br>&gt;<br>&gt; Much closer to the link quality is 34/94 or -61dBm.<br>&gt;<br>&gt; In neither of these locations a ping to the router will work.&nbsp;&nbsp;I always
<br>&gt; get &quot;network unreachable&quot;<br>&gt;<br>&gt; Also, the boot hangs for quite a while at the dhcp stage.<br>&gt;<br>&gt; Thanks!&nbsp;&nbsp; Rob.<br>&gt;<br>&gt; &gt;<br>&gt; &gt;<br>&gt; &gt;<br>&gt; &gt; cheers<br>&gt; &gt; Jordi

<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;I'm not a guru setting up MadDriver, but at the physical layer I see<br>&gt; &gt;&gt;&gt;&gt;that you have:<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;Link Quality=16/94
<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;This is _very_ low, normally I won't expect success in data<br>&gt; &gt;&gt;&gt;&gt;transmission with a quality below 50%.<br>&gt; &gt;&gt;&gt;&gt;
<br>&gt; &gt;&gt;&gt;&gt;I also see that you are connected at 36 MBps, this can be due to the<br>&gt; &gt;&gt;&gt;&gt;low quality in signal also.<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;I recommend you disabling the WEP encryption until you set up the
<br>&gt; &gt;&gt;&gt;&gt;connection correctly, just to make things easier. Then you can also<br>&gt; &gt;&gt;&gt;&gt;try to:<br>&gt; &gt;&gt;&gt;&gt;- Fix the transmit rate in Atheros config file: try first to fix it to<br>
&gt; &gt;&gt;&gt;&gt;11M and then check the link quality. Keep increasing it until you see<br>&gt; &gt;&gt;&gt;&gt;that the quality decreases<br>&gt; &gt;&gt;&gt;&gt;- If you're using dhcp ensure that you've obtained a valid ip from the
<br>&gt; &gt;&gt;&gt;&gt;server<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;That's all :)<br>&gt; &gt;&gt;&gt;&gt;Hope it helps you<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;&gt;cheers<br>
&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;Hi Jordi,<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;I have confirmed that my laptop works with WiFi when WEP is disabled.<br>&gt; &gt;&gt;&gt;However, setting the transmit rate to 11mb/s didn't do anything.
<br>&gt; &gt;&gt;&gt;It does appear though, that with WEP, the laptop hangs at the DHCP<br>&gt; &gt;&gt;&gt;stage, where it finally times out.&nbsp;&nbsp;I assume thats the first time the<br>&gt; &gt;&gt;&gt;WiFi system attempts to send or receive data.
<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;I will try to get closer to the access point to see if it is just a<br>&gt; &gt;&gt;&gt;problem of signal levels.&nbsp;&nbsp;However, in Windoze, I have plenty of signal.<br>&gt; &gt;&gt;&gt;
<br>&gt; &gt;&gt;&gt;If all else fails I may try alternate means to get it running.<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;&gt;Thanks!&nbsp;&nbsp;&nbsp;&nbsp;Rob<br>&gt; &gt;&gt;&gt;<br>&gt; &gt;&gt;<br>&gt; &gt;&gt;Right next to the access point I am still having problems.&nbsp;&nbsp;I think
<br>&gt; &gt;&gt;there is something wrong with the WEP function.&nbsp;&nbsp;&nbsp;&nbsp;Rob.<br>&gt; &gt;&gt;<br>&gt; &gt;&gt;--<br>&gt; &gt;&gt;<a href="mailto:gentoo-laptop@g.o">gentoo-laptop@g.o</a> mailing list<br>&gt; &gt;&gt;
