If all you're doing is the command line then theoretically nothing needs to be done before or after unless you've installed something that messes with it (which is the only reason a reset would work in the first place). So, theoretically this might fix the problem but if it does it might break something else.
Is there any way to see if it's a general network issue before going the way of no return? If your computer is a laptop, try connecting from someone else's network.
