My cell is one of the PLC pilot communities of Zhongtong Feihua. I started using it since I started more than a year from May 2003, and the intermediate was deactivated for a few months.
Use the power line to access the Internet, this idea is good, it can greatly facilitate home users to access everywhere, as long as there is a free socket. However, it is actually limited by the actual connection between the home wire. If there is a high-power appliance, or some brands of mobile phone charger, the Internet effect is interfered.
The speed of the Internet is generally good, it can reach 200-300K when it is good, and it is generally no problem. I downloaded with BT, occasionally stabilizing the speed of about 1 hour, mainly to see if there is a fast seed.
I was in this community after the original wiring, and I have changed 2 times, and the access device used by the device has changed three kinds. The first kind of Lancome is particularly useless. In less than 1 month, it is broken, and there is even one that I just changed at noon. I went home in the Internet at night. I used it for half an hour. At that time, the quality of the equipment used in each building was not good, and the self-test is often restarted. This makes me very sad and will soon handle the service. After a few months, I saw promotion promotion, one play, said that it was transformed a dry path, equipment, and also changed a black cat. Since the application's ADSL is not open, I have to try PLC. This effect is still possible, and the speed is definitely faster than ADSL, but it is still unstable, and there is often a case where it is often broken. However, the cost is cheap, 400 yuan for half a year, free of first-cost. However, it took 4 months. When this year, suddenly not normal. Later I heard that the line transformation. When the service expires, the new cat is replaced, and the renewal method is 400 yuan for half a year. Send in February, it is abnormal before compensation. It feels like this, so I will renew. This time is a white cat, the first cat took a few days, when I opened the switch of the patch panel, I burn it, call the after-sales service, after a multi-week, there is a radio, come to the door to replace. Using the current cat does not have a problem, but the connection is still unstable. Because it is a USB interface, you need to stop the device first, then unplug its power plug, then plug, so that you can usually reconnect.
If there is someone in the building to use the PLC, then a local area network, it can see the other machine name, but generally have security, can't go. However, all kinds of network virus attacks are quite powerful, my firewall keeps issuing alert, but fortunately, the firewall is well protected, and there is no loss.
There is no public IP with PLC, which seems to take an address. Sealed the ping function, it is not forwarded, for a general Internet, game, chat, upload download, MMS online is OK, but use MSN unable to speak, you can use MSN's video, or use QQ voice.
