I'm curious, Wang Jia so many people?

Lenovo sells to several, all Wang surname, the King also arranges the main line ...

It reminds me of the wonderful walls of my pharaoh.

The following questions were encountered this morning:

1 Questions:

Because the switch does not have enough sockets, add a lower router. By the main road by the separate link two switches and a path by, two switches and paths by the re-link room computer;

So here's the question (which one of the excavator schools is strong?) ）

The first thing you have to do is change the router's WAN. Otherwise the two routed WAN defaults to a 192.168.1.1 conflict. May cause some of the machine can not be on the network (this morning did not appear, unclear).

How to resolve:

Change the two-routed WAN to a different one. No conflict is better;

2 questions:

Second, the computer room installed operating system and software are all used in the network with the transmission, then the problem came ...

Big Switch and road by all are high, gigabit level, speed do not worry about the basic 20M per second speed of the same transmission (a system 15 minutes), but the path by the two computers of the same transmission speed of about 500KB (the same system 2 hours). Severely slows the overall speed. The same pass is like a bucket of water is the same, the speed often depends on the slowest one;

How to resolve:

On the issue of the same transmission, separate transmission: the first to pass the big Switch, and then put which two lines into the big Switch, the two separate to the machine transmission;

3. Question:

Do not let students on the wireless.

How to resolve:

Hides the wireless (implemented by turning off the SSID broadcast) and sets the password. See http://jingyan.baidu.com/article/154b463150a8b128cb8f416b.html

4. Question:

Network cable problem: There is too much old link is not on the device, measured by the tester found that the indicator light is so bright: 1 2 3 4 5 3 7 8

That means 3 lights up two times. 6 but not bright, changed very many times the crystal Head is useless (a beginning to think the problem of Crystal Head), may be the line of which place the Line 6 line has been crushed.

How to resolve:

Replace the position of line Line 6 (Green Line) with another location.

Principle:

We look for regular use of common cable head standard sequence: orange, orange, green white, blue, blue and white. Green. Brown White. Brown

We used only four, 1 2 3 6th, namely: orange, orange, green and white. Green. It's no problem just to have the four sequences and the lines unblocked.

Now the Green Line is out of the question (not through), and then replaced with other lines, I changed to: Orange, orange. Blue white, blue, brown white, brown, green white. Green in this order. This will not use the problematic Green Line,

So, we will be able to surf the internet normally, hahaha.

Oh, yes, forgot to write, Master Wang said he had won the scratch card, and gave me a look. The prize is a car worth 390,000. Master Wang said he would call later to confirm the matter. The child, he said, he wanted the car to drive into the money 35 bay also became. Hope is true. Master Wang is very good.
