Wi Fi Help needed


Recommended Posts

This is one area where I know next to nothing.I recently put together a desktop PC for my girlfriend,but she only has a cell phone as far as internet connection possibilities.Since she lives in a condo in the center of town,the possibility of Wi Fi hot spots seem good(right near a University/Starbucks/Airport ect.).Since Iv'e never needed this before,I'm not sure what to buy card wise and I'm a little confused by specs(802.11b/11g,11 mbps ect.).Also since her condo is a bit enclosed and probably just out of range,I'm sure I'll have to connect a more powerful external antennae(buy or build) to this card.I don't want to spend too much on this venture(in case it's not possible),but I'm not really sure where to start or what to buy.I saw this Belken Wireless PCi desktop network card(Model F5D6001)at New Egg www.newegg.com/app/ViewProduct.asp?submit=manufactory&catalog=31&manufactory=1450&DEPA=1&sortby=14&order=1 Which seems to come with a small external antennae that hopefully can be replaced.Then I'm seeing small radio cards that connect via USB.What do I buy? How would you go about this?

Well,since Iv'e played music for a living all my life and never worked in an office and still have a free dial up IP I never had to deal with this sort of thing.I must say it's seems a bit perplexing.

You'll want an 802.11g spec card, as that (54mbps) is the emerging standard, and is also completely backward-compatible with the current wide-spread 802.11b standard. Which means that one card will access both types of wi-fi networks. Some people in the corporate world use 802.11a, but not too many, and you won't find it as a standard in nearly any wi-fi hotspots.

 

You can go to a 1/2-wave antenna, but it's not going to gain you too much if the signal is already weak and has to penetrate the outside walls of the structure from the outside. So don't get too hung up on modding the antenna on a consumer-level (read: affordable) card.

 

As to signal boosting? Most public wi-fi network access points are fairly localized as to coverage, so you'll need to go fairly close to where they are to get any signal worth using. If your girlfriend is lucky enough to live next door to one, a wireless repeater can help boost the signal level, but only if it's already accessible, even weakly, and there's not a lot of other RF junk in the same bandwidth. Hotspots located in downtown areas lose range quickly because of all the other things sharing the same frequency range.

 

Once you get above the consumer-level gear, wi-fi gets very expensive very quickly, and it will quickly become more economical to get a dial-up or basic DSL connection than it would be to sink lots of money into directional wi-fi arrays and signal processors.

Al,

 

I'm not sure how you've going to get internet access.

 

Feeding off an existing w-lan?

Subscribing via cell service?

 

If you plan to piggyback off existing wifi signals, check if they require authentication first.

 

You can get a wifi finder for $10-20 bucks (Kengsington makes one) to see WHERE in that area you're getting a usable signal...

Thanks guy's,I'm getting the picture.I actually saw the Wi Fi Finder in Staples and almost bought it,now I think I will.If I dont get a signal in her condo then it's on to the cell phone.Anyone ever connect to dialup via a cell connection?Is it horribly slow?

Cell phones will be slow as hell. Even the new 3G ones over here top out at 380 kbs.

 

I think you can connect over bluetooth, at least you can with my phone and Macs.

Here\'s the antenna you need. For snooping out access points you can use Net Stumbler .

 

I've heard good things about the Orinoco PCI cards, probably find some other recommendations on The Net Stumbler site. Although the 802.11g standard is available, it's being implemented very little, and probably won't be for a good while.

best thing is to buy the sniffer and really everything locally. this way you can take them back if needed.

 

over 1/2 the networks will be unsecure..as in homeowners not setting security.

 

the best will will be the A/G cards they will be the most compatitble. my experiance with signal boosting antennas you can buy is they suck. you will need to make one.

do a search for "war driving" this will get you all kinds of ways to boost.

 

it will be hit or miss. as to the cell phone..

she may need to buy another phone and then the service aint cheap plus it really sucks. slower than a modem and drops out alot.

i tried this for my wife who does craft shows and had it connected to her laptop to process credit cards. what a nightmare. now we just take our chances and process when we get home. even in an area with a very strong signal it was poor at best.

Regarding wireless antennas: I think the problem at these radio frequencies is that even though you can have an antenna with some gain, there's too much loss in the coax/feedline.

I just went over to our neighborhood Starbucks to inquire. It's seem that to use their wi-fi you have to subscribe to T-Mobile?? She said it was sometihng like $30 a month?? Is this right? Kind of a disappointment. I think the coolest thing is to drive around and pull out the laptop at a hotspot like an apartment complex and jump on line. I suppose if I was traveling a lot it would be worth my while to pay for a T-Mobile account. I suppose it's got to be more useful than just to hang out at Starbucks, huh?

All the best,

No, no, all you have to do is find your nearest Panera Bread Cafe; they have all the free Wi-Fi you can handle if you buy a sandwich and coffee from them! NEVER pay for Wi-Fi at a public place if you can go down the street and get it free for the cost of a sandwich! Here is a link to a directory of free spots for Wi-Fi:

This way, no, wait, that way!

Funny,she dumped T-Mobile because it had too many dead spots in favor of AT&T.Anyway she has a desktop so the trip to Starbucks is out.She decided to get a landline so she'll connect free that way.
