A multimodal Codex session diagnosed an eight-year home network problem from photos in one sitting
An r/ChatGPT post at 858 upvotes describes eight years of slow upstairs internet, $300 spent this year on a Google mesh system after a failed Verizon extender, and a PC pulling 22 Mbps down. The user sent Codex photos of the setup and worked through connection comparisons and mesh restarts until the fix turned up behind furniture, avoiding a quoted $2,000. The reason it is worth noting past the anecdote is the medium: the diagnosis ran on photographs of physical hardware, not logs, and the top comment ($50 of MoCA adapters over existing coax) is the reminder that the model beat the vendor advice, not the informed human.
