I've been using a Belkin wireless USB adapter, so I decided to buy an additional adapter. I bought and then returned three Linksys adapters. Two connected by USB and they wouldn't work. Linksys said they were defective. Then I bought an internal adapter that connected directly to the motherboard. I couldn't get it to work either although it did detect my network. Linksys support wasn't helpful because their people apparently don't speak English that I can understand. I'm now back to the Belkin and it's intermittent connections.

What to do? (- Before I take a hammer to the thing!)

Large number of Internet users believe that, with the leading technology, 3G wireless networks can replace the cable network and wireless LAN. The reasons are as follows:
1. Faster network:
For the 3G wireless speed, and now we know that the rate of the three major carriers are now basically at the 3M. Through technological upgrading in the future, the speed will be much faster, and higher than the general boradband.
2. More convenient of using:
Now, to the Internet, users must plug the Internet cable, or find a nearby wireless hotspots , while in the 3G era, where has 3G signal can it access to the Internet. To the internet users, it is more attractive to go internet by this way.
3. The richer application:
Generally, 3G network can not only operating the existing application of the broadband network but also can rich in their own applications.
4. Lower cost to access:
Less equipment it should be used if need to access to the internet. Although the charges are still very high now, but I think that the fee will be reduced later to the price that public can accept.]]> Tue, 13 Oct 2009 14:04:54 +0000 http://forums.pcworld.com/index.php?/topic/67989-will-3g-wireless-networks-replace-the-local-area-wireless-network/ http://forums.pcworld.com/index.php?/topic/67935-controlled-access-within-simple-peer-to-peer-netowrks/

- For management to have downward access to all computers, but not upward access

I see no easy way to configure this in the regular networking windows or file sharing options.

Is there any (affordable) software that would make this an easy setup?

I have a similar problem with some variations. This week all attempts to go online have been met with the "Limited or no connectivity" message. I'm only using a wireless connection (excepting my backup Netzero dial-up... like right now) and NOTHING has changed in the last year in the hardware. I have an AMD 2800+ PC, 1 GB RAM, XP sp3 (updated from sp2 in 2008) and a Hawking-based wireless RAlink 54g card with +8 db gain antenna. Same cables and hardware, PC location unchanged, no wires damaged and no other PC's networked. I'm also using Avast and Zone Alarm, and d/l XP updates by hand irregularly (I do recall a single XP update about the time I let Firefox go to 3.5.3). The local freenet is coming in 5 bars at 36-48 Mbps all this time. 2 weeks ago, the wireless wouldn't connect.

This had happened before... most times after I updated Firefox. Usually, after a week and several reboots and shutdowns, all goes back to normal. I also try the repair connection util in windoze and that sometimes helps. This time -for the 1st time- I get the "limited" message. Used the repair util several times and each time it fails with an "unable to renew your IP address" response. I turned off both firewall and AV, no effect. I used the command line "ipconfig" utils but this only confused things (some IP's changed to 0.0.0.0, and I wish I knew what they are supposed to be since I only have the one wireless IP and Netzero dialup). Went into the registry to check the various addresses there. Many different xxx.xxx.xxx.xxx and subnets. Changing them caused problems (the 56k modem disappeared from the internet connections list among other things) and I went back to a saved registry from late July to recover. However the "limited" connection persists.

I've seen that MANY others have this problem from online queries. The more I look into this, the more I wonder if MS is forcing us to upgrade our OS, since they claim Win Vista/7 will stop these errors. Stangely, all the Win2000 and Win98se PC's I work on (some mine) have no such errors to connect. I'm on the verge of loading Ubantu Linux for this and other annoyances, if I could ensure a seamless change over for my games, email and social networking. Any ideas??]]> Sun, 11 Oct 2009 07:17:04 +0000 http://forums.pcworld.com/index.php?/topic/67849-receiving-limited-or-no-connectivity-messages/ http://forums.pcworld.com/index.php?/topic/67822-streaming-to-itouch/
The next step is to stream from my main computer (desk top) to the ITouch. Why. Sometimes I'm listen to radio stations who broadcast in a Adobe Flash Player format which ITouch cannot use.

Secondly, sometimes it would be nice to watch a movie i have on a DVD on my ITouch without first should convert it and download it to my ITouch.

So, are there anybody who can help me in setting up streaming from my main computer to my ITouch?]]> Sat, 10 Oct 2009 13:57:37 +0000 http://forums.pcworld.com/index.php?/topic/67822-streaming-to-itouch/ http://forums.pcworld.com/index.php?/topic/67571-remote-computer-networking-for-cyber-clinic/ Friends,

Myself Chirag Majamudar from India, Gujarat, a new member of PC World. I m working as a PRO-[censored]-Co-ordinator in VIROC ( Vadodara Institute for Reconstructive Orthopaedic Care ) Hospital managed by Nirman Orthopaedics Pvt. Ltd.. It is basically an Orthopaedic hospital for Joint Replacement Surgery and other Orthopaedic Treatment.
Now come to the point, We want to establish a Cyber Clinic in Madhya Pradesh, India. We want to treat our patients from here. Whether they are operated or new ones.For Surgery patiens should come in Gujarat, but for new patients and of course for follow-up they dont have to come in Gujarat. They will be treated at their own place. We want to establish a Cyber Clinic at 5 different places, area in Madhya Pradesh.
So, for that which kind of Software, Hardware, Routers, will be required. In a nutshell, tell me in detail what should we do to run Cyber Clinic in remote areas.
Please give me reply. As we dont have much knowledge about Computer Hardware.(Though Now-a-days I m learning Computer Hardware and Networking Course )

Waiting for your reply.................

Here's the situation:
When we deploy, we need to have three computers networked together that can all access the internet. We will not know the source of the internet beforehand (could be a CAT5 cable, more than likeley some kind of wireless signal).

Our resources are 3 computers (2 HP DSC5000's and a Dell tower), a Linksys BEFSR41 wired router and a AirLink USB Wireless adapter.

I was planning on using the Dell as the 'gateway' computer (least used). I connected all three computers to the router and...success! I can see all machines and they can see me.

I installed the AirLink USB and could not get internet. When I disconnected from the router (or disabled the NIC in the Network Connections list) I could get internet.

I did a little reading and found that to share the internet connection on any pc using Windows XP, you need to have one machine with a 2nd NIC. Off to the store to get one. While there, the 'network guru' said to get a TrendNet Wireless N gaming adapter...said it would work as a 'bridge'...told me to connect it to the on-board NIC, then set the 2nd NIC to 10.32.0.1, and connect that pc (the Dell) to the WAN port on the router.

He said to set the router to IP: 10.32.0.X (?), gateway: 10.32.0.1 and DNS: 10.32.0.1. That was supposed to let the router assign any IP to the 'client' PC's.

I installed the 2nd NIC on the Dell (slowest and least used) and connected it to the router. The on-board NIC is connected to the Trendnet. As soon as I enable the 2nd NIC (router), I lose internet connection. When I disable the 2nd NIC, internet returns. When I disable the on-board NIC and enable the 2nd NIC, I can see the other computers on the router, but no internet.

The NIC's do not have any conflicts (verified in hardware manager).

When I attempt this on the other two HP's using the AirLink wireless adapter - same thing...one adapter must be disabled to allow the other to work.

I'm at a complete loss. We have a drill on Saturday where we want to showcase our command trailer. We are an all-volunteer group, so we don't have the money to hire a network guru to come to us and get this up and running. I'm as close to a geek as we have, so the Captain is expecting me to get this to work.

Does anyone have any ideas what I should be doing or what I'm doing wrong?? All machines are Windows XP pro.

Thanks in advance!!

This sounds like a good idea and also has some other features. The paint would also be helpful in stopping cell phone signals from being recieved or sent outside of any area you have painted with this aluminum-iron oxide additive to any paint. This could be useful to theather operators, hospitals, schools and any where the management decides cell phone usage to be undesireable.
