i know how to bridge but this time on a differnt wireless connection I tried to bridge from my laptop to my 360 it work ok for like 5 min then it went off now my internet is not working. can someone tell me what went wrong and do anybody know how to fix it
Bridges and CSMA/CD Networks
Suppose two LAN segments A and B connected to each other by a bridge. In the steady state (when bridge has learned the locations of the computers on both segments) the bridge will forward the frames from one segment to another segment if necessary. There is concept of parallelism, it means after bridge learns the locations of all the computers the two segments can be used simultaneously.
Suppose on segment A there is a communication going on among segment A’s computers and segment A is not idle, at the same time a computer on segment B senses the medium and found that the medium is idle and sends a frame to another computer which is on segment A.
Now what happens? Bridge will receive the frame and now if bridge forwards this frame on segment A then obviously this results collision, Question arises is, Does bridge will store this frame in its memory and senses the segment A to become idle so that the frame can be transmitted?.
Second question, suppose a computer comp1 on segment A sends data to another computer comp2 on segment B, Comp1 senses the medium and finds that the medium is idle and sends data but at the same time comp2 senses the medium and finds that the medium is idle and sends data to comp1. Frame of comp1 and frame of comp2 both reaches the bridge at the same time, what the bridge will do? Is both the frames collide inside the bridge? Or bridge will store both the frames, which frame will be stored first? and if it stores which frame will be forwarded first ?
If I bridge my laptop and desktop together to use my laptop’s wireless card for my desktop, will my internet be slow?
Trying to get a linksys to intergrate with the 2Wire (already set up).
If thats too hard, how do i use the linksys as a bridge from the 2Wire to my xbox 360
sorry, the linksys is actually a router. Model is a wrt54gs v4
Energy-efficiency Electronics Hardware a “Bridge Fuel” to the future
Demand for energy continues to be a major topic around the world. Renewable energy sources such as wind, solar or hydro power are increasingly being utilized to provide for that demand. Many States have even recently passed laws raising the minimum renewable usage cap that utility companies must implement into their overall supply. But … we still require escalating amounts of energy for agriculture, industry, and to heat our homes and offices. Emerging as a “bridge fuel” to clean energy and renewable resources, the power electronics industry is poised to span that gap with hardware solutions needed to build intelligent power systems.
The Obama administration plans to spend billions of dollars on power conservation and sustainable energy projects as part of a 7 billion stimulus package which is has focused on energy efficiency. Andrew Fanara, of U.S. Environmental Protection Agency’s Energy Star program has famously said. “Energy efficiency is the bridge fuel we must build on and must invest in” he stresses “Energy efficiency is the cheapest, cleanest, fastest way to act.”
In part, the administration’s strategy is to use improved energy efficiency as a method of buying time to invest in and explore emerging and clean energy options. With initiatives like the smart power grid gaining traction, the power electronics hardware that makes it all work and its new designs aimed at increasing energy efficiency will be at the core of the plan.
Already, there is huge demand for power efficiency by consumers found an industry survey. And, consumers are willingly paying a premium for electronic hardware that delivers energy efficiency. This trend anticipates a growing number of electronic hardware devices will be utilized, which lowers costs and drives improved energy efficiency. Measured in dollars per watt this high volume of hardware deployment forecasts the efficiency for power electronics may drop to as low as 12 cents per watt by 2013.
The focal point of “smart power” systems and a national smart energy grid has clearly been on the hardware side of the equation. To be successful, in the not to distant future, engineers will also make use of the intelligence provided by software so that the hardware components communicate most effectively to accomplish maximum reduction of power consumption. The know-how exists now for this integrated software, but it is still far from widespread.
Power Profiling is a valuable energy-efficiency tool that granularly identifies the power consumed specifically by HVAC, appliances, networks, lighting etc. and communicates this information to users. A user profile is developed by use of proprietary algorithms that calculate information regarding a structure’s overall usage, and several data points such as the time of day and its energy consumption history.
The purpose of power profiling is to enable users to know exactly what activities or systems are consuming the most power, including how much, and how that consumption is affected by actions they take. Most HVAC and appliances are not yet enabled so numerous hardware metering devices are used throughout the structure, at least an adequate number to demonstrate to the user what the largest power users are and how to limit consumption.
Home Area Networks (HAN) are increasingly communicating with utilities in addition to the traditional media centers and computers. Both utilities and consumer electronics companies are offering and assortment of hardware solutions with methods of pre-programming and remotely controlling home systems such as water usage, heating & cooling, and appliances. With the arrival of “smart” appliances and new wireless network protocols designed specifically for energy-efficiency, many of these hardware solutions communicate to users and utilities over one or more wireless systems.
ZWave for media and home automation
ZigBee chosen by utility companies because of it’s secure protocol, and
EnOcean a European self-powered energy harvesting technology that powers devices without the use of batteries.
Hardware using these wireless protocols can all be controlled from a single point building management system, or a homeowner’s computer. Even though these technologies are still on the leading edge, trends indicates they are very near to wide-scale adoption, enabling buildings to connect to smart grid applications that exponentially increase energy-efficiency.
Advances in alternative energy sources have provided greener ways of producing electricity and the burgeoning energy-efficiency industry is providing a plethora of energy saving hardware devices to help users re-tool . We can reduce energy consumption with these advances and make strides toward energy independence. Consider what T. Boone Pickens says “In additional to putting our security in the hands of potentially unfriendly and unstable foreign nations, we spent 5 billion on foreign oil in 2008 alone. That’s money taken out of our economy and sent to foreign nations, and it will continue to drain the life from our economy for as long as we fail to stop the bleeding.
Projected over the next 10 years the cost will be trillion – it will be the greatest transfer of wealth in the history of mankind.”
“By investing in renewable energy and conservation, we can create millions of new jobs. Developing new alternative energies while utilizing natural gas for transportation and energy generation; securing our economy by reducing our dependence on foreign oil, and keeping more money at home to pay for the whole thing.”
Moving forward with renewables is a must, but it is also a documented fact that this increased capacity will not be enough to meet upcoming demands and provide energy independence. The tremendous strides being made in energyefficiency technologiesareto help stem the tide, bridging the gap.

Intel’s new Sandy Bridge processors
Thought I would mention something about the new sandy bridge line of processors that Intel came out two days ago. Its using the latest 32nm technology and has a completely new architecture. The PCI-E slot is on the same die as the memory and video controller thus shortening the distance required for communication. Why is this important? Well for one it shows a change in the industry and we could at some point in the near future no longer need gpu’s at all.
Intel also changed the previous plans of using the 1156 socket and changed it to an new 1155. One pin difference. Typical really, just another way for them to force people to buy whole new pc’s. Its also not going to be supporting DX 11 for awhile and users will be forced to use DX 10.1.
Here’s a very interesting quote from wikipedia, well kind of scary really actually.
“In addition, Sandy Bridge processors will implement security features that include the ability to remotely disable a PC or erase information from hard drives. This can be useful in the case of a lost or stolen PC. The commands can be received through 3G signals, ethernet, or internet connections. AES encryption will be available for both video conferencing and VoIP applications.”
When I first read that quote from wikipedia yesterday I didn’t think I was reading it correctly. How scary is that? Being able to disable a pc from anywhere. What next? Wi’ll law enforcement agencies get the power to do this? This could really end up a disaster. With technology comes accountability I guess.

I purchased a linksys USB bridge to hook into my xbox360 but the system is not recognizing it when I plug it in. Is there some type of installation process that I need to do?
I am curious if I can utilize both connections for faster upload and download speeds. Is there a way to "bridge" the two, or would I have to have a specialized network card that has that capability? I’ve seen the dual network card in action in a 50+ host environment and it’s pretty "snappy".
Is there any kind of slot you can get to make it work or are those cards just strictly for laptops? I ask b/c I have one laying around and if it would work for my desktop rather than buying an adapter/bridge that would be great.
Okay, I have a wireless router(D-Link) throwing internet throughout my house. I have an Xbox 360 at the other end of the house. I don’t feel like buying an Xbox wireless thing because I don’t have the money and I don’t have a cord long enough to run all the way to the 360. But, I do have a Netgear wireless router just lying around. I would like to wirelessly bridge these two together so I can get Live for my Xbox. It would look like this:
D-Link router…………………Internet
|
(Wireless Connection)
|
Netgear router………………..Xbox 360
Can’t figure out how to do this. Can anyone help?
