Wireless card in the room no signal, I would like to extend the line to the card to send a good place to achieve the purpose of the Internet, but bought (Shengshi Changying) the best 20 meters extension line, and bought the HUB2.0 with power (USB front panel rear panel are tested) appears network card is not working properly, the card constantly detected and disconnected, detected and disconnected, constantly appear ding dong ding bucket of the tone, I consider Or the reasons for lack of power supply, but said the power shortage I also added a power hub, ah, ask friends there are other ways to solve this problem? Make the card work properly on the line. Urgent! The Online Thank you for more
I do not know how you use, 20 meters line consumption is too large, not only power, signal levels are likely to fail. 220 + 5v power supply as close as possible to the wireless card ---- is an external +5 V power cord can not exceed 50CM, not enough, it is estimated that the signal part of the connection should also use thick usb cable to change the resistance to reduce the internal resistance.

You ask this question is too broad, no way to answer in detail. The principle is the same, copper row due to a single flow area is large, so the dynamic stability and thermal stability are better than the cable, so the high current load or power supply is generally connected with a closed bus, but the copper is rigid connection so long distance Need to install retractable section. Use of the occasion: the use of copper busbar, the use of copper between the cabinet to connect more copper, dry and low voltage cabinet connected to the use of copper, generators and booster connection between the use of copper. Use of cables between other electrical equipment connections. Another: the price of ordinary copper is much lower than the cable, but the price of closed bus is far more than the cable.
