I saw a fea people with a similar problem, but I'm not sure if it's really the same situation, so let me ask you:<br><br>1- You have the same problem everywhere? I mean, on different places with different APs?<br>2- What are you using to manage your network connections? netcfg, networkmanager, wicd, ...?<br>
3- If the answer for the first question is that you're having this trouble with only one connection (AP), is this one using WEP, WPA, WPA2.. ?<br><br>best,<br clear="all"><div><span style="border-collapse:collapse;font-family:arial,sans-serif"><p>

Hi,<br>
<br>
I have D-Link DIR-655 wireless router, though I think it's Linux issue.<br>
I'm using kernel 3.5.1, but I had same problem with 3.2 and 3.4 as well.<br>
<br>
Time to time, I get "carrier lost" message on "wlan0", and then "dhcpcd"<br>
exits, followed by shutdown of all network connections, even statically<br>
assigned wired "eth0" is down.<br>
<br>
