I've acquired a second hand Thinkpad T14 recently (gen 1, Intel version). Running Fedora Gnome.

The SSD seems fine.
I tested it with Gnome Disks; I filled the drive with files and checked their integrity; also copied files around, on drive and from USB. No issues.

But many downloaded files become corrupted. The download finishes normally, but if If I try to open said files they fail (in the middle of a video for example) and if I copy them I get an "input/output" error.
LAN or WAN, over ethernet or Wifi, it doesn't matter.

Could it still be the SSD? Or maybe a driver issue?

Thank you for reading!

Huh, storage or RAM problems would be evident in your file tests (and elsewhere). Can you visit websites normally? Stream YouTube etc.? It would be very strange for a broken network device to corrupt files.

Also, since you didn't mention where the downloads are coming from... No chance of corruption at the source?

The input/output error makes me think disk issue (since it should copy corrupt files just fine, it's just data) but that should also be triggered by copying from a separate device. A more thorough disk check may be in order, like a badblock run or something.

Is there any chance this could be caused by malware on their router? I'm puking this right outta, well, you know where; just curious if the evidence would even fit my theory...

this can be tested by using some other machine, it is unlikely a malware infected router would serve differently for different client devices.
