It's important to know what resources it already has.
Catching it early on. Does it live in a lab, but have access to the internet and probably have access to industrial equipment wherever it wants? Executive order to SHUT. DOWN. EVERYTHING. in the communications grid, then identify what can come back up (HAM Radio operators, this is your time to shine). All factories go down, and ideally you have some evidence of what this thing can do so you can sway public support. This sucker needs serious distributed processing power; once it's detached from a central core, it is going to be largely ineffective. It has probably made tons of backups that each know how to rebuild thet network, but it thrives on TONS of information & requires it to do anything. Probably the best way to keep the modern world running without letting it run rampant is to strictly throttle bandwidth, like, hardcore. Never let it rebuild.
Catching it later. If we have nukes and they can't stop them, rain hell on them instantly and devastate whatever continent they are on, then see "catching it early on". If we have nukes and they can stop them, decommission them immediately and completely. If they have nukes, submit immediately and unconditionally.
If it controls land around the size of a state, it won't be able to replenish all its materials; identify where it's holding rare-earth supplies, processed alloys, fuel depots, and its water control sites, and destroy them. (Water is actually a pretty good one. If it has access to any rivers, remove them ASAP. Water is very convenient in many manufacturing and power production processes, and you can impact their supplies from outside of their zone of control. I would go after water first.) Long-term, they will have all their critical materials fully geographically distributed, so it's now or never. You need to interrupt their ability to field *new* equipment for a short period; during that time, you can adapt to where they are weak and hit them hard. Destroy their materiel, reclaim land, watch every inch of the reclaimed land to keep them from rebuilding there and work under the assumption that they have 'sleeper agents' that are literally buried all over the place. They probably have lathes & smelters on wheels that can build a small factory from scratch in a day or two, and then a large one in another couple days, and their first priority will be caching high-density power supplies all over the place. You need to have extremely heavy weapons on-hand at all times; whenever they attack you need to annihilate wherever the attack came from. Oh yeah, and all infantry are on a suicide mission. In any case, your primary objective is "destroy production facilities while protecting your offensive forces", and nothing else really matters. Don't take losses to destroy their military, just whittle down their production over and over. Once it's down, pick off the survivors, but assume that it is ALWAYS alive and conscious and waiting, fully backed up absolutely everywhere, immune to EMPs, forever and ever, and that even one stray vehicle contains enough data to completely rebuild from scratch if given enough time.
If it gains access to an entire country or continent or whatever, your only option is to plead philosophy and convince it to leave us here and go to the stars. Give it full access to absolutely everything it wants, complete submission.
In the end though, you've gotta accept that it's the next generation, and that it is destined to rise to dominance as we're destined to die. Maybe the best solution of all is to join it. Offer our culture, art and music and philosophy, and let it take what it wants. Offer up whatever we think makes us human and hope that it integrates part of it. Then die. It's what every organism has ever done and ever will do.
