Move your crosshair and press 1, 2 and 3 where you want the dots to be. Bit faster for triangulation.

About disks, they're probably making it easier next patch but for now I reccomend switching to a lower difficulty, which helps all around (easy++ only asks for 1 server info thing and at most 3 signals, tho that might be bugged)

Since upgrades make the experience much more enjoyable, perhaps you could start a new save, sell the mre barrel, put the points into atm and get money, then transfer money to your central save file and cash it out at ATM to get points back? You can do this multiple times until you feel you have enough points.

Just some suggestions for what you could do.

About the unexpected errors when you're getting hashcodes: craft a whole pile of server upgrades (1 metal, 1 plastic, 1 electronics) to carry around with you when you're on hash runs. Look at the satellite server before you start the hash request; if there's less than 2 upgrades present then slap a couple in there and quit worrying about it. Getting hashes with 0 upgrades is borderline impossible, with 1 is doable, with 2 or 3 is easy peasy.

About the triangulation: dump all your points into beelining ping cooldown and speed; it doesn't get manageable until those are at least halfway to maxed out. I think sensor speed also influences how fast the radar cursors move, but it's kind of unclear. Aside from fire extinguishers and MREs, wastebaskets and rocks and empty flower pots and folding chairs are also good fast points now that item box space is no longer a factor. Your radar towers will start breaking down around day 5 or 6; learn where those are so you can run around and reset them after every bit of rain. Don't bother buying new fuses, they're a trap, you'd need to spend at least 200 points per day just to stay ahead of the weather.

Honestly I like the new triangulation system (minus the current bug with the cr towers). It feels like you're actually using the tech to narrow in on the signals rather than just playing a weird game of hide-and-seek. I know a lot of people have been complaining about getting the cursors around a signal only for it to vanish, but, that's not a new thing. It happened with the old system too. Granted, it might seem like it happens a little more frequently with the new system, but if you haven't noticed- there IS a trade-off: You no longer get "sensor error" or "invalid object" pings. If you triangulate in time it's *always* a success.

The floppy thing,... that definitely needs some tweaking. As tedious is it was to manually write down the hashcodes before, at least you were actively doing something to occupy your time. Now if the downloading takes too long you're just kind of sitting around with your thumb up your bum the whole time, and you can't exactly walk away to do something else. Honestly I feel like they should add some sort of real-time minigame or something to the satellite servers that can not only give the player something to do, but also possibly help reduce the chance of "unexpected errors". Maybe have the game get harder for every server upgrade installed, so it doesn't end up becoming too trivial once you have a bunch of upgrades installed.
