Help Me Set Up Wireless and Wired Network on New House

I LOOKED INTO IT:

This may shock you so I hope you are sitting down – Wireless DOES NOT pass through brick walls (or concrete)! It also has a hard time going through glass if you have Pilkington K glass, the K bit is a metal coating to conserve heat loss, this alone can kill the signal by 30%. It does pass through wood and plasterboard, but it is weakened significantly, but if the plasterboard is foil backed, again due to energy efficiency you will have problems. I am talking about the 2.4GHz wireless as opposed to the newer 5GHz wireless which will pass through these, although any more than 1 brick thickness and again you will have problems. Looks like wireless is not all it’s cracked up to be huh.

Seriously,
I woudl keep the router in the same rom as your Game systems. You dont quite have the rooms completely done and set up. Instead of going crazy about if you get signals through the walls and glass. I would test it out. Keep the router in that room and then test it out when things get completed.

If it comes down to where your not getting enough signal from that router in the other rooms. We will be more than happy to suggest a good AP and how to router it to the other rooms.

You shoudldn't stress so much on something that may not be required.

But the cables need to be connected to the router, so I need a place to put the router, because then I can set up the cables.

The walls are made of bricks, I think the wall in the PS3 room, is about two bricks, where exactly you suggests me to put the router in the PS3 room.

God I'm tired, thanks.

well you can set your DSL or Cable modem anywhere but as long as you run that CAT 5 cable anywere to your router it shoudl be fine. Just place the router in view of the window so the attennas are in plain view of everything. Then hard wire your ps3 as well. Very important becuase your ps3 is 10/100/1000 as well and the router can support that.

I need to make a few corrections to your post:

Wireless does pass through brick walls. Brick is actually fairly RF friendly but it does depend on what kind. It's what's behind it or embedded in it that can cause problems. It also passes through cinderblock and unreinforced concrete if it's not too thick. Rebar is not your friend.

Drywall is also very RF friendly unless there's something else behind it that will affect it like the foil backing you refer to.

Metal studs can create a problem as well. They don't cut signal but can create multipath interference (too many reflections). MIMO relies on some reflections but too many can still creat a problem. 5GHZ is even more susceptible to multipath than 2.4GHz. The higher the frequency the more it's affected.

Uncoated glass is fine. Glass with a metallic coating is just about as bad as a metal wall. That would be your K-Glass. Glass with non-metallic coatings are usually ok as well. Security glass with the embedded metal wires is also bad.

I have quite a few years of wireless under my belt so I felt a little clarification was called for.

I got that from another site. I didn't quote it. But on my behalf. Thank you for clearning it up for me. At least it helps me out in the future but a true networker does not use wireless *lol* hardwire all the way!

and you think the cab5e is suitable for me or you would recomend the cab6?
And about the devices, if i plug the adapter at the notebooks, them they would support all the features of the router right? So what is the deal about this:

802.11n won't give you it's full capability unless all the devices connected to the router support gigabit ethernet (1gbps). But even with standard fast ethernet (100mbps) it's faster between devices on the router. It won't help your dsl connection though.

and the dir-855 have wan port right? Why do i need a dsl modem?
Thank you again, waiting for your next reply

technically to run gige you need cat6 cable. But cat6 is more expensive and uses special rj45 connectors since the cable is larger in diameter. But you can get away with cat5e since your runs are pretty short. Less than 15 meters i'd bet. If you want cat6 go for it but i'd bet you'll be fine with cat5e.

An ap or wireless router that supports 802.11n will have gigabit ethernet interfaces. Full 802.11n can go up to 300mbps or even faster so why would you use 100mbps ethernet? Right?

you can use 5e... That is just fine as well.... Its not like your doing industrual networking your only doing house... So 5e is just as fine.

Your ap is going to be whatever the ap is. I guarentee you that your not going to reach those 300 speeds or even the 1000 speeds but having those speeds are good just incase you want to add more to the network it is capable of handing everything in your network. Pushing out all that data.

I use gig because i have 4 desktop and i have lan parties and i need those speeds just to push all that game data all around the network.

I also have vonage and everything else on the network that takes bandwidth.
