In a café, Xiaoyu is looking for the wifi password, cannot get connected, and then manages it.
Xiaoyu
您好，这儿有无线网吗？
Nín hǎo, zhèr yǒu wúxiànwǎng ma ?
Hello, do you have wifi here?
The waiter
有。名字是店的名字，密码在桌子上。
Yǒu. Míngzi shì diàn de míngzi, mìmǎ zài zhuōzi shàng.
We do. The network is the name of the café, and the password is on the table.
Xiaoyu
我没看到，在哪儿？
Wǒ méi kàndào, zài nǎr ?
I did not see it, where is it?
The waiter
就在这张纸上，最下面。
Jiù zài zhè Zhāng zhǐ shàng, zuì xiàmiàn.
On this piece of paper, right at the bottom.
Xiaoyu
找到了。我输了密码，还是不行。
Zhǎodào le. Wǒ shū le mìmǎ, háishi bù xíng.
Found it. I have entered the password and it still will not work.
The waiter
再试一次。有时候人多，网就慢。
Zài shì yī cì. Yǒushíhou rén duō, wǎng jiù màn.
Try again. When it is busy the network slows down.
Xiaoyu
好了，可以了，谢谢您！
Hǎo le, kěyǐ le, xièxie nín !
There, it is working now, thank you!
Chen Hao
网快吗？我要发几张照片。
Wǎng kuài ma ? Wǒ yào fā jǐ Zhāng zhàopiàn.
Is it fast? I need to send a few photos.
Xiaoyu
不太快，但是能用。
Bù tài kuài, dànshì néng yòng.
Not very fast, but usable.
The waiter
楼上人少，那儿快一点儿。
Lóushàng rén shǎo, nàr kuài yīdiǎnr.
There are fewer people upstairs, it is quicker up there.
The sign says 无线网, "wireless network", and sometimes 无线网络. Spoken aloud, almost everyone uses the English word, pronounced as two syllables in the Chinese way. The commonest question is 有无线网吗 or, shorter still, 密码是多少, since everyone knows which password is meant.
我没看到 says I did not see it: the thing did not happen, and that calls for 没. 我不看 would mean I refuse to look, or that I do not look as a rule. The rule fits on one line: 没 for what did not happen, 不 for will, habit and the future. Only 有 is an exception, always negated with 没有.
This 还是 is not the one that offers a choice between two things, seen in lesson 10. Here it means "all the same, still": 我输了，还是不行, I entered it and it still will not work. The context keeps them apart: a question offers a choice, a statement records a persistence.
