Most engineering students can't engineer their way out of a wet paper sack.

For the most part, the kids aren't too bad. It's the teachers you have to watch out for.

I have never had a good experience with an engineer. Most think that if something works on paper it will work in the real world. I've seen a couple of engineers have to eat their paper after being presented with the data we gave them. The funny thing is that most engineers feel that the survey sections are the necessary evils of their labor. Yet they cannot design anything without the data the surveyors give them. So glad I am not a surveyor anymore. I don't have to deal with engineers now.

If he did any reading on the forums he would have (hopefully) come to the same conclusion.

going from upstairs to basement good luck. There is a concret base, so it somehow has to go above the walls to where the stairs are and go down from there. its not simple.

I've tried A few times, I can go into my addict and almost get it down to the main floor but from the main floor to the basement i've yet to find a way. I was thinking of going from the basement up but havent had the time.

I really didnt like that comment of how you think I think your all kids... its not true. I know your experts thats why I came here and asked to do my testing because I know I am Mechanical not Electrical so you would point out points i would have missed.

I've setup HUGE homes with 1 AP and its Excellent to VERY good EVERYwhere in their homes. I know what I am doing. But usualy I can place the router in optimal locations.

The DIR-655 "802.1n Draft 2.0 WiFi certification" So it should be the next closest thing to the real N.

brwrdrvr> I just did a count. I've networked (wirelessly) and sucessfully 26 homes (not including mine). All with one router.
I've always gone for the Linksys wrt54G speedboost. I got 20 of them on special at somepoint for 35$ each Huge homes I buy the 7dbi antennas makes a nice difference.

Can you guys Please explain this point to me. I am a little lost on this one.
"different frequencies react to different construction materials"
Really??? I thought all the channels are in the 2.4Ghz range just off by a little. i didnt think it was enough to make a difference.
I just use netstumbler and use farthest away channel from everyone else.
For example around my home i have a few using 6 and 11. Nobody using 1. So I set mine up to Channel 1.

Barry > Psst I am actually a very good engineer in a few groups. I am part of the schools F1 team i am part of the team tuning the intake manifold. Fluid Dynamics

Sorry for the delay in the reply I had quizes to study for :P

I use an Airlink MIMO router and get a good signal even when I went into my 20 foot aluminum skinned camper trailer to see just what signal I could get.

worked real good in there.

Thank you for making my point for me. Not every situation will be the same when it comes to RF. There are too many factors that play on the way the RF distributes throughout the building. As you are learning with your house now. I just wish you would have done more reading before you came in here with a half-cocked experiment and boasting your results. Thus the mbolglian comments. Everyone has the capacity to learn. Well, almost everybody. Those who cannot learn end up in the Bin.

When I mentioned construction materials and RF I wasn't talking about just 2.4gHz. I was talking about ALL of the spectrum. Knowing this information will help you in the long run. If you are that interested in learning about RF and RF theory then read a few books on the subject. I think some of the guys in here have written a few things on the subject. (Opened the floor for a plug from some of the regulars here.)

For some fun you can read the other thread the OP started in another forum: Linksys WRT300N VS Dlink DIR-655 VS WRT54G - dslreports.com

Edit:
I just noticed something I'm surprised nobody else noticed at this point, he's using an unsupported card with Netstumbler so his Netstumbler readings can be promptly thrown into the bin where they belong. Takes an engineering student to not read the Readme docs apparently.

I have watched this since the noise level picked up just wondering when someone would notice that small detail and call BS.

I didn't bother with it, because there's been so much BS here, including the 26 homes with excellent coverage with 1 AP in each. Unless each home happens to be an open dome with no walls, I find it hard to believe that the people are getting adequate coverage.

I was wondering about that same thing. I was wondering if the houses he was referring to was an outhouse. It's small enough for an AP to cover the whole thing.

brwrdrvr> I learn pretty quick.

Here i'll tell you what I usually do.
I turn on all the wireless systems on and run netstumbler on them. Then I try router in different rooms where its possible to put the modem. The location that has the best signal I leave the router there and i try different antenna positions. Then I check which channels are already occupied and i try one thats not used or least used. and check signal strength again. if its better i keep it, if not i try anouther.
I usualy install WRT54GS so i have dd-wrt firmware and i start to boost the power (up to a max of 70mw). and keep watching the signal make sure its good on all of them.

so its more like a trial an errors method.

itsnotme & MikeP928 > The card is very new i didn't think netstumbler would have an updated faq that talks about the card. But i ran netstumbler and it worked, it running intermitently i thought had to do with the driver or since its running on USB.

streaker69 > emmmm how do want me to prove it to you.

By the way I live in Canada so houses are made in a huge square fashion with 3 floors (Basement, main floor and top floor) and we use WOOD not Cement and concret because they are not good insulators. We use Wood for the entire house.

I know in Florida and such you guys have duplexes and one floor house.

So thinking if the router is in the center of the house there is a max distance of 14 Meters

There's so many things wrong with this post that I'm not even going to try and reply to each mistake. I'll tell you this though, please read the Readme and note where it says that the only supported card is cards that have the Hermes chipset. Anything else will not give you accurate SNR's.

I live close enough to Canada to know what the house structures are, and if you're going to insinuate that they're all the same, you're not an engineer. period.

Do some reading around here and get your head screwed on straight and start doing some better research! You're an engineer in study for god's sakes! You should be able to do better research than what you've shown here.

First off, only one person that replied here is in Florida, and the reason they don't have basements down there is because if they did, they'd have an indoor pool as well.

My house is 2 floors plus a basement, and I guess it's much bigger than your Canadian homes, plus it's wood, but yet, I still need multiple AP's for adequate coverage. I guess the building materials used up there don't block RF the way building materials down here do. Or maybe RF physics are completely different up there.

Render, have you done any study on RF characteristics in the Great White North?

I'm not going to comment on building materials and insulation.
