lester Posted July 18, 2013 Share Posted July 18, 2013 Hello, I'm running linux mint and have never had a problem connecting to a wireless access point on wlan0 and keeping the connection for hours. However, once connected to the wireless access point and then plugging in the network cable that runs from the Mark IV with the most recent version of pineapple OS, my wireless connection is disrupted or disconnected altogether. Any obvious reasons why this might happen? I run the script wp4.sh and everything connects properly, but shortly thereafter I lose my wifi signal on the laptop. An ifconfig still shows the wlan0 with the proper ip address from the wireless router, but I cannot ping anything or access the net. Help appreciated.

thesugarat Posted July 18, 2013 Share Posted July 18, 2013 Doesn't Mint use Wicd as the network manager? Try removing the Eth port from being managed in there. There are a few posts here about this issue. Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted July 18, 2013 Share Posted July 18, 2013 As stated above. Most likely your network manager is taking over. Quote Link to comment Share on other sites More sharing options...
pseud0 Posted July 18, 2013 Share Posted July 18, 2013 Stupid/simple trick to try. In the network manager edit the eth0 connection and uncheck the box that says use that interface by default. Otherwise you will connect to your target WAP with wlan0 and have connectivity, but when you plug in or ifup eth0 the network manager will flip you over to that interface thereby breaking your wlan connection. Right click on the network manager icon, select wired tab, select wired 1, click edit, uncheck "connect automagically". Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted July 18, 2013 Share Posted July 18, 2013 Yeah. I have mentioned that in other places on the forum somewhere lol. Quote Link to comment Share on other sites More sharing options...
pseud0 Posted July 18, 2013 Share Posted July 18, 2013 Yeah, I'm sure this isn't new. It's just fresh on my mind because I ran into earlier this week with a fresh kali install. Took me 10 minutes of swearing and editing the interfaces file before I remembered to turn that off. Quote Link to comment Share on other sites More sharing options...
lester Posted July 19, 2013 Author Share Posted July 19, 2013 Okay I've unchecked that and it seems to be working properly. Thanks! Here's a stupid questions: what's the difference between "Automatic (DHCP)" and "Automatic (DHCP) addresses only" in the IPv4 settings tab? I can't slice the semantic differences here and can't find an answer through Google. I was wondering if this might have something to do with the problem. Thank you.

Mr-Protocol Posted July 20, 2013 Share Posted July 20, 2013 When you set the Method to Automatic (DHCP) addresses only, the ignore-auto-dns= value will be true - you must change this to false to both get your domains added to the search path and use the DHCP-supplied DNS servers.
