Questions & Answers about lùyóuqì méiyǒu xìnhào.

What does 路由器 mean, and how is it used in everyday Chinese?

路由器 means router, usually an internet or Wi‑Fi router.

• 路由 = routing
• 器 = device / instrument

So the word is basically routing device.

In everyday speech, Chinese speakers do use 路由器, but in casual conversation some people may also just talk about the Wi‑Fi instead, depending on what they mean.

Example:

• 路由器坏了。 = The router is broken.
• 路由器没有信号。 = The router has no signal.

Why is 没有 used here instead of 不有?

In Mandarin, 没有 is the normal way to say do not have / there is no.

You generally cannot say 不有 in standard Mandarin to mean don’t have.

So:

• 我没有钱。 = I don’t have money.
• 这里没有人。 = There’s nobody here.
• 路由器没有信号。 = The router has no signal.

A useful rule:

• 不 is usually used for habits, general negation, or future actions.
• 没 / 没有 is usually used for not have and for did not in the past.

Can I shorten 没有 to 没 in this sentence?

Yes. In spoken Chinese, 没 is very common and natural.

So these both work:

• 路由器没有信号。
• 路由器没信号。

The shorter version is especially common in conversation.
