A router is a device that connects computers (or other type of computer
devices) to each other on a network and you can send files
from one computer to the other. It does not connect to the internet, and
you need a device called a modem vaguely to do this. The modem also
connects to the router and allows the computers on the network
(those connected to the router) to connect to the internet.

However, note that there are some available devices that are
router-modem combination. If your router is of this type, you do not have
need a modem.

    Always display the complete text and correct all errors when you ask about a problem.

    ISPS don't like people using their networks to forward mail from other networks.  The symptoms you describe are usually the result of not properly is authenticating with the outgoing server or the use of a non encrypted SMTP connection (that is, port 25 instead of 587 or 465 or whatever your email port provider requires for encryption).

  • How to distinguish between couples that comes from my TX CAN oppose and frames which comes from the network?

    HY,

    I have an object can pass data to the specific id.

    I expect to get frame from the network with IDs and similar data.

    How will I know that the data came from the network?

    (If I listen to the data of the CAN Interface, I can't distinguish the data that I convey and between data from the Internet)

    Thanks in advance,

    Aviad

    Since you are using NI-CAN, series 1, which does not support no matter what Self-reception, I assume you are using two ports CAN... make your normal transmission and the other to listen to the frames of the CAN bus?

    If this is the case, the only option I see for you would be to compare the charge received with the load transmitted to detect the images you send. This will only work if you send and receive different payloads, but it's probably something that's generally true. If it is false, then you really have no good option with the 1 series (or even series 2) and NI-CAN.

    We have a different product, OR-XNET, which provides a forum for independent reception (such as series 2 NI-CAN), but when you receive the framework that it contains a flag that indicates if it was received from the network or received through self-reception. It's of course far easier (and probably only guaranteed) way to achieve your goal.

  • Need a cable Modem (have an Airport Extreme)

    I am a subscriber of internet high speed from Comcast in the Chicago area.  I have their most recent Wireless Gateway that supports the 802.11ac fall on my newly upgraded Airport Extreme.  I'm looking to buy my own cable modem and seeks recommendations based on the information.

    Anyone who wants to help out? Thank you!

    In fact, I would like to start with modems that that Comcast will be supported. The only ones you should avoid a potentially are the Arris / Motorola SB61XX-series modems as they have been known to be incompatible with airport base stations.

    For recommendations, I suggest you Cisco, as the DPC3008 models.

  • Why is there not a "right_click-> Send_URL" I can send a URL without having to open it first?

    Very easy to send a picture by clicking right on it and then selecting "send Image". Why is there not a corresponding 'Email Link' (i.e. send link) when the mouse cursor is over a hyperlink?

    The only way to do this now is to actually open the new page (in a new temporary tab), then use the "File->Email Link..." from the File menu, then kill the temporary tab.  Simply adding this to the right-click menu would make this soooo convenient.

  • Desktop computer connected via a cable to a wireless router - can't print on Photosmart Wireless B109n-z

    Hello

    I have my desktop (Windows XP) connected via a cable to a LinkSys WRT54GC wireless router and wireless HP Photosmart B109n-z connected wireless. I can 'see' desktop printer if I write the IP address of the printer in the browser, but printing does not work.

    I don't know how to set up the printer to print from this desktop computer. What I choose when installing printer drivers (printing via USB or wireless?). I tried manually installing printer but without success. Do I have to set up specific ports?

    Printing from laptop (connected wireless to the router) works perfectly.

    Thank you in advance for your answer, I'm really lost on this one.

    Choose print wireless while installing the software.  Because the printer is connected to your router, you don't need to go through «setup USB wireless»

    I'll try to manually add again in this way:

    Verify that you can access the web page internal to the printer by its IP address.

    1. click on the 'Start' button--> printers and fax machines.
    2. under print jobs, click on "add a printer".
    3. click on 'Next' on the Add Printer Wizard window.
    4. Select "local printer attached to this computer. Deselect "automatically detect and install my Plug and play printer." Click "next".
    5 under, select a Printer Port option, select "Create a new port" and choose "Standard TCP/IP Port" and click "Next".
    6. in the "Welcome to the Add Standard TCP/IP printer port Wizard" make sure that the printer is turned on and connected to the same network that your computer is connected to. click on the button "next".
    7. under "Add Standard TCP/IP Printer Port" enter the IP address of the printer. Click 'Next' and then click 'Finish '.
    8. now select HP in the manufacturers list, select your printer in the list of the models of printers and click the button "next".
    9. If you can't find your printer, you will need to find the installation CD and use the 'Disc' option to select one of the files hp*.ini. You can also select another model of the same type HP printer.
    10. Add the name of print spooler, and then click "next".
    11. click on "next".
    12. click on "Next" and "Finish."
