    Post Wireless Access

    I finally had time to configure my new 802.11b stuff this weekend.

    To annyone who is thinking about wireless stuff, for internet / uploading, songs, etc
    I highly recomend it.

    Im using Linksys "instant wireless" series of cards and access point.

    When Im at home, the car is seen as a std PC over a tcp/ip connection. I can send files to it, use VNC to remote control the pc ( for making changes to configs) and (you would need to be really board to do this) you can sit in the car, and surf the internet ( as long as I dont get to far from my house) In fact, im siting in the car right now

    I need to put up some outdoor antenni , see if I can boost the range... hey I just thought of something.... I cole have some monitors running on my server, and when the server sees the car ( Im coming home) it could turn on the lights, and tv...unlock the door, open garage.... and when it sees im leaving it could turn everything off.

    hummm, found a new project.

    Well, for annyone thats interested - I got mine on sale from bestbuy.com 1 access point and 2 pc cards for 400.00

    Sounds really cool. Just wish I had an extra $400 after I get the system finished

    How far of a range? I have my truck in the garage at my apartment complex and I am 2 floors above it with brick walls. Do you think it would work? My cordless phone works down there so I think it should. Also, what transfer speeds are you getting?

    With my access point inside, on the second floor, and my car in the parking lot, I get a "fair" signal, as reported by the software (it goes poor, fair good, excelent)Im geting an 11 Mbps conection. Thats with about 50 feet between them.

    Here the specs -

    Indoor:
    50M (164 ft.) @ 11 Mbps
    80M (262 ft.) @ 5.5 Mbps
    120M (393 ft.) @ 2 Mbps,
    150M (492 ft.) @ 1 Mpbs

    Outdoor:
    250M (820 ft.) @ 11 Mbps
    350M (1148 ft.) @ 5.5 Mbps
    400M (1312 ft.) @ 2 Mbps
    500M (1640 ft.) @ 1 Mbps

    I just did the wireless thing too..

    A little more work with linux, but it's working well. I am using the D-Link Card and the Linksys WAP.

    I'd be interested if you have any luck with extending the range.. I really think the card is the part that suffers on range, but I could be wrong.

    Nester,

    Just wondering - I started with the dlink hub, and linksys card. It worked fine with no WEP, but when I turn on WEP, they dont talk.

    I never tried the dlink card with the linksys wap, butI was wondering if you are using WEP with your WAP

    As for the antena, I do agree, having an external antena for the pc card would help alot.
    An interesting note on that, My old wireless card was external from the pc, it sat on the back shelf of the car (in the rear window) and it had an excelent range.

    The new card I got is pcmcia, and goes into a pcmcia adapter mounted in a drive bay. and that means its enclosed in the trunk ( boot for all you UK's) when I pop the trunk, the signal streginth jumps.

    Some of the REALLY expensive cards have external antena ports. check out <a href=http://www.breezecom.com/Products_2030.asp?tNodeParam=33> Breezecom </a>

    Wellllll... WEP doesn't work at this point. I'm told it's a linux driver issue by the driver people. I got it to work once. never again. However, i put the card in a windows box for a while (to make sure it worked) and I seem to think that I had WEP turned on at the time and that it worked. I could be wrong however.....

    I really want to get WEP working since I don't want anyone roaming on to my network. I'm sure the chances are pretty low for that anyway.

    You could use X10 modules for this. See http://www.x10.com .

    thought of that..... wouldnt work the ame though,

    I need to be able to tell the difference between the car coming home, and the car leaving. 802.11b uses true diversity antena(anteni, whatever) and has the ability to display signal streginth, I would use signal streginth to determin if the car was coming home ( signal starts weak , and gets stronger) or, leaving ( signal starts strong, and gets weak) the x10 stuff to mk knoledge has no API for signal streginth. and I would need to modify the transmiters to stay on while the car was on... the pc is already set up for it.
