Test Telecom 3G Internet under Linux system

I have set up a 3G internet equipment for telecommunications. This one is not cheap. Even I want to say that I am a loser, but there is no way, no, no, I am a person who can’t live without the Internet, although I never use it. Qq, meager … …

Equipment

The last equipment I chose was this: a 3g wireless network card, for the signal to be placed on the side of the window, a 5 meter long usb Extension cable, one network card, one end 3g wireless router, or directly connected to the notebook. NIC I bought Huawei ec122, measured under linux, 3g wireless routing I bought Mercury products, built-in 2000 mAh battery, emergency power can be used as mobile power, when the power outage can be 4 hours.

Huawei ec122 is set up under linux, I am not enough, so it is set in the graphical interface. Click Set Network Manager, Wireless Connection tab, I am an English system, I don't know what Chinese is called. After plugging in, I will not automatically create a new connection. At least my kernel seems to be 3.2. I will not recognize it manually. NIC, select the network card when selecting the device, and then select the region as china, the operator will automatically identify China telecom, ie China Telecom, select this, and then fill in the username and password, according to the Internet, it seems to be unified, Username=ctnet@mycdma. Cn Password=vnet.mobi, then click Finish. Right click on the network manager and connect to the wireless network.

Premium Card I am the legendary 1 card from Taobao, no monthly rent, no minimum spending, no call expiration date, billing on time, 1 minute 1 cent, which is 6 hours an hour This is expensive enough. Then this card is not worthwhile, because it is a time card, whether it is cost-effective or not.

Speed ​​

I tested it, under Linux, use Firefox to download the files under Thunder offline. The speed is 60k/s – 150k/s diving (extension: detailed: 4M broadband download speed is), and the actual assumption is similar. But beware, firefox comes with a very simple single-threaded http download, and finally can safely return the lossless file, at least that the wireless connection is very stable, although the speed is unstable.

Finally, I downloaded the 148m file at 24 points. According to this speed, I can go down to 370m in one hour. The price of 1 hour is 6 pieces, so the price of dragging 2GB is almost 32. Go to Taobao to buy a 2GB traffic card, at least 66, not counting postage, telecommunications and Jingdong are more expensive. So it is still worthwhile.

And 1 card has another advantage, 0 month rent, 0 minimum consumption, means no need to spend, do not need to pay for maintenance, you can use it in case of emergency, this is any tariff card The advantages that are not available.

Also note that this is the conclusion of the single-threaded download during peak hours (7:00). My location is close to the city center (if it is in the suburbs or the countryside, the speed will be relatively large) Impact). What if you use the download tool? If you avoid the peak hours, the speed can be stabilized at 150k? If the weather is better? Of course, this is only a hypothesis, but if it comes true, the cost will drop by about one time.

Finally, I am still very dissatisfied with the 3g tariff, but only for the emergency, this is still a burden.
