wireless N - A signal can go through 3 storey house??? Pls. give me some advice.

Before I'll order Lattitude E6400. I've some question about wireless network. I've heard that wireless N - A signal can go far than 2x , if compare with wireless G.

In E6400 series , there is an option for wireless : 5100 , 5300. The one I'll choose is 5300 wireless N (best option)

Is it possible to use wireless N for 3 storey house. I' ve plan to located ADSL modem on Ground Floor. Is it possible that a signal can run through 3rd Floor.

Are there anybody know that we can use wireless ADSL Modem in this case???
A signal - How far can it go?????
Pls. give me some advice.

PS.I don' want to extend a wire from existing modem. Just change to a wireless modem and I can use it for one desktop on ground floor and one laptop(wireless) on 3rd floor. Is this right???

 

Concrete floors or wooden floors? That will make a very big difference to the signal propagation.

It might help if you position the router so it is close to the stairs.

Thank you for your advice.
My house is Concrete Floor. But the upper level, it's on the same position.
Is it possible that a signal can get through concrete floor? 3 storey w/12-15metres on vertical line.
So,Is there a problem from other signal? just like a signal from mobile phone, etc.

 

Two or three concrete floors is going to be a significant barrier to signal propagation. It is likely to be worse than having a similar number of solid walls between computer and router since the floors will have steel reinforcement which will tend to help block the signal.

Putting the router next to the stairs is your best hope since some of the signal will tend to follow the stair well. that's what I would do. I know you don't want to fix any wires, but if you can't get a signal through then the next action would be to install a wireless access point somewhere up the stairs. That would need a single cable from the router. There are some relevant suggestions here.

Mobile phone signals are a bit different. They will tend to come through the windows or outside walls and avoid the reinforced concrete floors.

I think it will be fine. I use 802.11g at work and I've had no problems connecting at a reasonable speed (20Mbit/s or higher) at a distance of about 200 ft through two cinder block walls and a third made of drywall with galvanized studs. In a residential environment you'll probably be going a max of 50 or 60 feet and even with cement floors I think you'd not have a problem as "n" does indeed work further out than "g". What you shouldn't expect though is to connect at the fastest speeds available to an "n" system.

 

Signal boosters could help you, they just plug into the power socket in the wall, they aren't wired to the network at all.

You mean networking over power?

Ethernet over power is one option. A range expander is another option. It is effectively a relay between the router and the computer.

The best thing is for the OP to get his computer and see what works. If the signal from the router isn't strong enough then we have identified several options.

I'm not convinced, from the Intel info, that the 5300 offers better signal strength. However, it should have more bandwidth, if this is needed.

Is it possible for you to move the router to the second storey? I know with my DSL I can plug it in to any phone socket in the house.

Shouldn't be a problem at all. I can be next door, through several walls, and still access my wrt54gl access point no problem with the Intel 4965 card.

Presumably the new Intel cards are even better.
