Linux noob, MS power user for 20+ years, LL for life at this point (3 months now). Have reinstalled LL 3 times now for various reasons (moving to different partitions mainly, and preserving my win vista partition until I back up almost 10 years of documents/misc on it). Has worked amazingly well each time, but I am a tinkerer, so I have added unsupported repositories, finally found synaptic (it's kinda hidden, why?), edited config files, and ran unknown cli commands cut and pasted from the internet. Here is my current problem:
Latest install (3.6 upgraded to 3.8), everything was running as normal. I mess around with a lot of stuff (I run pi-hole, for example), and I may have "released" my DHCP lease in my router settings (I'm not 100% clear on what that means, I was probably trying to fix something else, following an online "recipe"). Now, in LL, it connects to the network, but no browser will load, AND apt-get update will not connect either - connected with no connectivity. Of course windows and other distros all have normal connectivity.
Questions: Is there a way to completely reset my internet settings? I'm not opposed to reinstalling the OS, but... can I reinstall in the same partition, or will it just leave whatever corrupted config files are there? (I do have "spare" partitions I can use... see ya Ubuntu, ha ha told you...)
Obviously (in retrospect) the DNS settings in /etc/resolv.conf were incorrect, the system was looking to 127.0.0.1 (home) for DNS lookups for some reason. I was not able to install nscd... until I fixed this. Did not work the first time ... not used to, and don't like non-GUI editors, they have nothing to offer me. Yet. Thanks!!
