• Is it possible to connect a security DVR to Internet with LAN connected to this kind of device?

    Best answer: It makes no difference whether devices connect to the router by WiFi or Ethernet assuming the router supports both, which most do. You will probably have to set the DVR on a static address on your private network, and then configure port forwarding in the router to allow connections from the Internet to that static address. If your ISP... show more
    Best answer: It makes no difference whether devices connect to the router by WiFi or Ethernet assuming the router supports both, which most do. You will probably have to set the DVR on a static address on your private network, and then configure port forwarding in the router to allow connections from the Internet to that static address. If your ISP provides a dynamic (changeable) public IP address, then you will probably need to use a DDNS service such as dyn.com or noip.com (there are others). This will give you a fixed URL that will point to whatever public address you currently have at home. You will also need a DDNS updater. Some routers include this facility. If your router does not, then you will probably have to run a PC with an updater App installed so that the DDNS server knows your current public address. If you go away and the ISP changes your public address 10 minutes later, you need to be able to conenct to the new address. I hope this helps.

    Best answer: There should be no problem putting a 1.65 GB masterpiece on a 4.7 GB DVD. You say that the laptop was updated. Does the DVD drive do anything now? At least the Windows DVD writing software should still work. There are two ways of putting a video on to a DVD. The first is to copy it as a data file. Although this will play on a PC, it probably will not play on a TV's built in DVD player. The second way is to master the DVD. This will convert the file into a format that normal non-computer DVD players can handle. My suspicion is that as part of the update to your laptop, the drivers for the DVD drive are either missing or are not compatible. If nothing works with the DVD drive, then go into Device Manager and see if the DVD drive is showing some form of error when you open its properties. If it is a driver problem, see if you can download and install the proper driver for the DVD drive. I hope this helps.

Assuming the computer's NIC is not configured to operate only at 100 Mbps, or the Ethernet cable is restricted to using only two conductor pairs, then the Ethernet from the computer to the switch will operate at 1 Gbps. However, if another device connected to the switch with which the computer is transferring data is only using 100 Mbps, then this will be the effective data rate between the computer and the other device.The 1 Gbps connection to the computer will only be active for 10% of the time.

  • What happens if the double slit experiment is done with many slits--is there a limit how many slits elecreons can simultaneously go through?

    Best answer: Each electron can pass through only one slit; however, when there is more than one slit different electrons will pass through different slits as their trajectories will never take them just towards a single slit when there are others close by. If there are a lot of slits, the distribution of electrons passing through the slits will... show more
    Best answer: Each electron can pass through only one slit; however, when there is more than one slit different electrons will pass through different slits as their trajectories will never take them just towards a single slit when there are others close by. If there are a lot of slits, the distribution of electrons passing through the slits will follow a distribution pattern depending on the initial direction in which the electrons are travelling and the alignment of that direction with the middle of the slit grid. If the beam of electrons is tight (well defined), then the distribution across a wide field of slits will fall off at the edges to the point where no electrons may reach the outermost slits. Unless the electrons are produced one at a time, the mutual repulsion of their negative charges will push them apart, and the degree by which they diverge will depend upon the velocity with which they are projected. There may also be a focussing effect if a positive charge exists close to or just behind the slits that further influence the direction in which they are travelling.

    Best answer: Quoted WiFi speeds from manufacturers are instantaneous burst speeds over very short distances. Since WiFi is a two-way alternate or half duplex protocol, this typically results in around 50% reduction to get the average throughput at short distances and low protocol speeds. At higher speeds and greater distances the average speed may experience a greater reduction from the instantaneous speed. Also, it depends on the capabilities of both the router and the connected devices. The instantaneous and average speeds can be reduced if there is a slower device currently on the network. The speeds you quote are not unreasonable as average speeds. I hope this helps.

    Best answer: If the ISP connection (AT&T) is only providing 18 Mbps, then you are going to struggle with more than one HD TV session running at once. Even at standard definition TV, at least half the ISP bandwidth will be accounted for by your 3 Hulu devices. If the security cameras are sending continuous video streams to the Internet, then that can be another sizeable chunk of bandwidth depending on the resolution and frame rate. As others have said, devices look for WiFi networks to connect to. It is not the router looking for devices. The router simply advertises its presence. There is no reason why a device that has previously used Verizon should not be able to connect to AT&T as an ISP. The only real answer is to get an ISP feed that is capable of handling the peak demand on the connection. You need to determine the bandwidth required by each device and sum this up. Add at least an extra 25% to 33% as a margin and go for that. In addition, putting a lot of devices on the same WiFi network at the same time is also a potential bandwidth bottleneck. Fixed high bandwidth devices such as TVs are normally better when they are connected to the router by Ethernet, assuming that they offer an Ethernet connection. Another possibility is to connect a wireless access point to the router and set up an additional WiFi network. For devices closer to the router, using 5 GHz instead of 2.4 GHz is another way of reducing WiFi bottlenecks; however, the ISP bandwidth from AT&T is the first thing to investigate. Note: The ISP connection simply provides a connection to the Internet. It does not carry Ethernet or WiFi. The ISP connection is converted to multiple Ethernet and WiFi feeds in a wireless router or gateway. I hope this helps.

    Best answer: I assume that you intend to access the security camera over the Internet when you are not at home. This is where you will hit a brick wall. You will need port forwarding in the landlord's router and any other router you install for you to be able to access the camera and get a live feed unless it is set up continuously to stream video to some external server that you can connect to. My own security cameras (made by Foscam) can accept incoming connections from the Internet with the appropriate port forwarding. This gives real-time image streaming with the ability to pan and tilt the cameras to look around my home. These cameras also include motion detection so that they can email images to an normal email service when they detect something is moving. With the images saved off-site, by the time someone finds the camera it has already posted the images to a remote site. The camera can also email automatically when my public IP address changes, so I can always find the current IP address from my mailbox when I want to connect for a live feed. Before you worry about encrypted WiFi and bridging, work out how you are going to get port forwarding to work if you want real-time images. I hope this helps.

    Best answer: 2014/15 is still a relatively recent computer. There are a number of reasons why the connection might be slow: 1. The wireless adapter in the PC might be using one of the older, slower 802.11 specifications. You have not included any indications of the speed this PC achieves or the speed other devices achieve, so it is difficult to comment exactly on whether a particular protocol adapter might be the issue. 2. The wireless driver or the operating system may not be able to achieve the higher speeds. There may be background processes that are loading the PC's CPU limiting the processing power to drive the WiFi adapter. For Windows, Task Manager may show a high CPU usage that could explain the problem. 3. There may be a compatibility issue between the new router (assuming you have a new router) and the PC's wireless adapter that is causing a slow connection. Incompatibilities can mean that WiFi connection simply does not work (the PC may not even detect the network) through various performance issues and random disconnections from the network. If the PC worked faster with your old WiFi, then this is normally a symptom of a compatibility issue. The Asus laptop I am using at the moment has compatibility issues with my latest router. However, I have installed a wireless range extender, which connects to the router and presents a different WiFi network that my laptop works with very well. I also have a wireless security camera which would not recognise the WiFi network from one of my old routers, but works perfectly with my current router. 4. The distance from the router and any intervening walls, floors, furniture, etc. Try using a different WiFi network to see if it makes a difference. Make sure you use the same network for this computer and for your reference device. I hope this helps.

    Best answer: It sounds like there may to two issues, although I found your question seemed rather confused. I guess you are talking about EPG (Electronic Program Guide) data. Many TV tuner Apps do not delete the obsolete EPG data, but keep adding to it. As the App gets new data, there may be several days of current data in the file, and rather than overwriting the whole file, it keeps the old data and adds more. This would account for the large size of the file if you have been using the App for a long time. I have seen this on one of my TV Apps. I normally delete the EPG file on my computer completely, then leave the App running to build up a new, but current EPG. After a few months I repeat the delete cycle. As far as the Recycle Bin is concerned, the storage for the bin is distributed between the drives on the system. If a drive is disconnected, then the contents of that drives bin storage will not appear when the Recycle Bin is selected from the desktop or File Explorer. When a drive is reattached, its local bin storage may not be re-indexed until the computer restarts. Note: Shutting Down then a power up of a Windows 8 or 10 PC might not be sufficient and an actual Restart may be needed. This is because, depending on various settings, when you shut down these versions of Windows it hibernates parts of the system rather than checking everything again. I hope this helps.
