Concrete but plain description ('the internet light on the router kept blinking red') and a simple but-clause keep the narrative clear without added complexity, Band 6.5 level.
The technology I want to talk about is my home Wi-Fi router. This happened about six months ago, on a Sunday evening. I work from home sometimes, and I needed to send some design files to a client before Monday morning.
The problem was that the router just stopped working. There was a big storm that night, with a lot of rain and thunder, and I think the power went off and on very quickly. After that, the internet light on the router kept blinking red, and no device in my apartment could connect. I tried turning it off and on again many times, but nothing changed.
I didn't fix it myself, actually, because I don't know much about routers. I called my colleague Khánh, and she told me to go to a twenty-four-hour coffee shop near Dragon Bridge, which has free and fast Wi-Fi. So I packed my laptop and worked there until almost midnight, and I managed to send the files on time.
Did I fix the real problem? Not that night. The next day I called the internet company, and a technician came and changed the router for a new one. It has worked well since then, but now I always keep a backup 4G data plan on my phone, just in case it happens again.

Why this band
- GRA“I tried turning it off and on again many times, but nothing changed.” — Two simple clauses are joined with "but," a basic and completely accurate coordinating structure that contrasts the attempted fix with its failure. There's no subordination here at all, no because, when, or relative clause, which keeps this squarely within the mostly-simple-sentences profile the 6.5 grammar descriptor describes. It's a natural way to report a frustrating, repetitive troubleshooting attempt, even if the sentence-building itself stays basic.
- FC“now I always keep a backup 4G data plan on my phone, just in case it happens again.” — The answer resolves with a plain statement of the new habit adopted, without any reflection on what the incident taught the speaker more broadly about relying on a single connection. A 6.5 response is allowed to end this directly, giving one clear resolution rather than a developed insight; a 7.0 or 7.5 version might add a short evaluative comment about how the storm exposed a hidden weakness. It matches the story's overall practical, matter-of-fact tone.
- LR“the internet light on the router kept blinking red” — This is concrete, visual, everyday vocabulary — "light," "blinking," "red" — describing exactly what the speaker saw, without reaching for a more technical term like "signal indicator" or "fault light." It's accurate and easy to picture, which is all 6.5 needs, but it stays at the plainest available wording rather than the flexible, topic-specific phrase a 7.0 answer might use instead. It also grounds the otherwise abstract "router stopped working" claim in a specific, observable detail.
