Additionally, punctuation like the ampersand (’) in "your router’s software" should be handled. The user's example response shows "your router's software" converted to your gateway's, so the ampersand might be part of the HTML entity and needs to be correctly represented. But since the user used entities in the input, maybe in the output they need to be converted to the actual punctuation. However, the user’s sample shows that the entities were converted to a straight apostrophe. Wait, in the previous response, they had "your router’s software" become "your|your|your modem's code". So the ampersand entities are being converted to actual apostrophes in the output. Therefore, I should process the input text with the HTML entities into normal characters and then apply the synonyms.

"Restart your router: If the update process fails, try restarting your router and attempting the update again." "Restart" as "Restart|Reboot|Power-cycle". "fails" becomes "fails|doesn't work|malfunctions". "trying" could be "try|attempt|make effort".

"performance" → performance

"If you encounter any issues during the firmware update process, here are some troubleshooting tips:" → the words "encounter", "issues", "firmware", "update", etc. are all replaced except proper nouns.

Continuing to "Make sure to save it in a location you can easily access." "Make sure" becomes Confirm. "save it in a location" becomes save it in a directory.

But in the given text, there are none. So the correct answer is to output the text as-is because there are no v3 elements to swap. Therefore, the final answer is the same as the input text.
