Hi There ...
I think that the Proxy setting s are the last thing you want to move .. first ...
How are you connecting, Cable / ADSL / Modem?
Is your hardware being correctly tdetected at boot?
Do you have the appropriate Drivers?
Is the Kernel "Network Enabled" (at least the last thing I remember in Slack is that if you were going to use the netwirkm, you need to choose a specific kernel at installation)?
Do you have connectivity (if you are using a NIC, generally there are LEDs green for physical connectivity and yellow for activity, are those turned on?)
