My boss asked me to install Ubuntu 12.04 LTS 32 bit on an old-ish laptop with an external US Robotics Wifi card and an internal ethernet card. I have gone through all the painful hops about installing the Wifi card driver, then suceeded getting wpa-supplicant to make it connect. Then I installed LUbuntu because I need to use Firefox on it. No Network manager or anything, as the graphic interface will only be invoked once a week and this laptop works as an "always on" database slave.
Now, I have several issues:
- I can only issue 1 ping before it completely stops communicating. That ping shall show 3 successful low latency replies then hangs till I CTRL-C it.
- Otherwise, I may succesfully open one (1) web page in Firefox and then it completely stops communicating.
- While I am at it: I need the Wlan to be the main interface. The internal ethernet interface gets only connected once a week. When it happens, it should be possible to telnet into it from other computers.
The first two issues seem related and also look like this previous question with the big difference I don't have Network Manager so I don't know where to look. That computer is terminal only with an afterwards attached thin graphic install. For the second issue, I don't know how to create the configuration to let it work. As of now both interfaces are unreachable from our LAN and I don't know if it's due to the first issues or not. In order to try debug the situation I have commented the built in ethernet adapter but I have not seen any benefit on the other. The wlan must be always on since boot and shall have a fixed IP address.
I am posting some of my (anonymized) configs below, if you are so kind to help me I'll post other configs as you feel fit to ask.
Thanks in advance.
