The double computer Internet problem upstairs downstairs?

Experts, I live in the kind of house with the attic, the computer room in the attic, which is just below a study.

Recently to the downstairs study also put an old desktop, hope and upstairs computer through no line by the same time Internet. The wireless router is in the upstairs computer room.

Ask questions: 1 Like me this is not a wall, but the floor, similar to Mercury m54r, such as the cable-free by matching its wireless network card, can you ensure that the downstairs study online? (Downstairs is just on the page, occasionally play the public)

2 tplink541g compared with the above mercury, whether the signal quality of my situation has improved significantly?

3 without line can also connect the Internet, right?

4 PCI wireless network card and USB wireless network card comparison, which transmission quality more stable?

5 with tplink541g and relatively inexpensive mercury wireless network card combination, is it easy to appear compatibility problems?

Attached: I use the telecommunication adsl,1mb bandwidth. Thank you!

The best answer:

1, Reply: 1, no line from the lower transmission quality to some, but specifically do not see the layout of your room structure, solid can not guarantee the signal quality. If there is a window or door, the effect will be much better. 2.TP and Mercury are currently working for the same factory, please see carefully. 3. No line from the Internet can be sure to connect network cable. The 4.USB interface is more stable. 5. There will be no compatibility issues. 54M of wireless cards are similar. I hope it will be of some help to you. If you have any questions, you can give me a short message.

2, the route should be placed near the window some. It's better to put it downstairs. But the computer room is now upstairs, and the tl-wr541g route antenna is 5DB, the signal is relatively poor. You can buy a router that can change the antenna, so you can ensure that there is no problem with the data transfer. For duplex building, the signal is stronger than the line. Routing can consult me, here do not say what type, afraid of others said advertising suspicion, have interest can short me.

3, look at your floor structure, I have just tried the office, received no signal, the router is TP 340, the lowest launch range of that section. But that is the office building, after the design of the floor, there are fire hoses and other facilities, as for ordinary residential I have no chance to test.

What about the 541, 641 series? The empty land is called 830 meters. In addition, you can add a router antenna plus a long line, so you can adjust the antenna position, and the USB interface card itself with a long line.

4, your situation is similar to mine. But I have a window downstairs 2 meters, no problem, no broken line (541 of the wireless route, T40 notebook) N95 mobile phone is no problem another difference is that the personal view of USB wireless network card signal weakness ~ or feel the PCI signal strong ( Personal opinions are not deepened).
