Repair the network infrastructure of the rental house
Today, I fixed the cables of my house.
The main reason that drives me to do is the weak signal of the wireless network.
I have a Netgear WGT624 v4, which is sending a very bad signal.1 One week ago, it’s about -50dB when I check it from the iwconfig. But yesterday, it’s just -76dB.
It’s true that there’re some antennae can work with the bad signal. But most of them just can gain 10dB. So this can’t be a final solution. Then I checked the preserved cables of house. It’s nice that they all roads to the SCTR weak current box. However, the cables is not connected, with no sign, and even have no RJ45 connector. It took me about two hours to pair the cables and make connectors for them.
Quite a heavy work. I learnt the order of the subcables from it. In Chinese, it’s 白橙 橙, 白绿 蓝, 白蓝 绿, 白棕 棕.
Actually, you can’t make connectors with the customized order. Because the subcables are in twisted pair, not just simple lines. So the electronic signal will interfere with each other if you got a wrong order.
Notes,
1. I want to but don’t know how to setup a DD-WRT or OpenWrt on it. Many appreciation if someone can help.
PS,
I’ve made a very nice configuration of compiz and terminator. It’s amazing to key down the shell commands/vim on the beautiful desktop background. Maybe I will try the awesome next month.
chars and words is now floating before the cloud.
