• WIRELESS and wired LAN do not know each other

  My internet provider installed a new cable modem, without capacity WIFI because I have an airport extreme base WIFI (with cable Express extensions).  Speed and quality are OK, wireless and wired, but there seems to be a wall of China between WIFI and wired (LAN): devices that are connected via a cable to my LAN are not visible from the wireless network and vice versa.  Airport extreme is not 'Bridge' mode ("because not of wireless on the new modem capability".)

  No idea of the reasons for this?  Thank you very much

  Sounds like the configuration of the device. With the airport devices it can operate as a device on the network or another firewall as its own network. I think that it is way jumpered to activate, this will allow you to configure the wireless on the airport, but your current router will do the DNS/DHCP and will be a single network.

  Now that you have configured as two routers on an independent network as there is no bridge.

• Wired LAN undetected on a Satellite U940 after installing Win7 Pro

  Hello

  After replacement of the HDD in the Satellite U940-100 and the installation of win 7 Prof 64 b the wired lan device is not detected. According to the documentation, there should be a 'Fast Ethernet LAN' in the U940.

  On the Toshiba support site, there is a Realtek driver available, but no luck. During installation a message appears: Realtek network controller was not found. The network cable is plugged in, but no led indicator. On the router the giga bit led will blink.

  There is no unknown device left in the 'management of the computer--> device manager'.

  Went LAN so where? Any suggestions?

  Thanks in advance,
  Frans

  > There is no unknown device left in the 'management of the computer--> Device Manager. "
  And what is stated in the network adapters? Realtek network card is listed there?
  This is really strange.
  Try to set the BIOS to default settings and check again.

• connect the m6220 switches stacked to existing Lan infrastructure

  I need to connect two powerconnect M6220 to LAN infrastructure existing.

  The switch of two are configured in the stack.

  Which is the best way to uplink the new switch to the other two powerconnect 5548.

  The old switch are not stacked and bound together by two 10GB Ethernet cable (one of the links is disabled).

  I need to implement the network tolerant to failures, maybe I need to configure the tree covering weight on the two links of 10 GB.

  I use Spanning tree to configure the uplink between the old and the new, too?

  Is there a better alternative? There is another way to prevent the loop network?

  Thanks, Francesco

  You have a few options.

  1. you can simply connect the cables between the M6220 switch stack and the 5548.  Set up a trunk connection which allows for VLAN needed overall.  Tree covering weight until it is enabled on the switch and not off on specific ports connecting the default switches prevent loops and allow the most profitable link to be active, leaving the second connection as an alternative link in a blocking state.

  2. you can configure LAG (aggregation of links).  This is where you configure the individual physical ports in a virtual port channel.  This indicates a covering tree to treat multiple physical ports as a single link aggregated to the other switch.  You will need to have the port at each end of the connection channel mapping. (On each switch).  This allows the same speed but more flow.  To move traffic more.

• Need help setting up a wired LAN lan games

  I try to understand what I have to buy an easy to implement the cable LAN.  Specifily more I'm looking for a router, switch, or hub.  I will be putting this LAN up aboard a commercial ship so it must be wired (too much metal for an efficeint wireless signal) and I'll proably a 12 people who want access to connect to an Xbox 360 or PS3.  This LAN will never have access to the internet.  In the future there may be more people who would like a connection so I would have the possibility to connect two switches together (1 switch by the bridge of the ship).  but for now I'll just implement 1 Platinum that I have only one available output to power a switch/router/hub.

  Key factors

  1. you are looking for something small price

  2 you can connect at least 12 people

  3. simple and detroit before implementing.

  4 hold a model specific linksys product so I can read about the installation process.  That way if I need to assign IP addresses, I can make it in advance and make installation as soon as possible.

  You can opt for a router (8 ports) BEFSR81 or BEFSR41 (4 ports) followed by a network switch EZXS55W/EZXS88W/EZXS16W (08/05/16 PORTS). No need to put the IP address for the computers that you can use the DHCP from the router to the switch and the computers.

• Adding a switch to a Terminal Airport Express

  I need to add ethernet connections to a box in my house. I have currently a router (WAN/LAN)-> Apple Airport Extreme-> via WiFi--> two Apple Airport Express. I need to add more ethernet connection where the Express is, I can add one, say Netgear, switch connected to the connection to the LAN of the Express and expand my network with say 5 additional ethernet ports?

  Sure.  Do not forget that the Express has a 100 Mbps Ethernet port, so any device connected to the switch will be limited to 100 Mbps, even if you have a switch to 1,000 Mbps.

• Jet 7 Wired LAN Access (not WiFi)

  Anyone know if HP Jet 7 can connect to a LAN wired using an external USB adapter? I didn't know if the operating system can support the correct driver and if the port USB 7 stream the output of the power supply.

  Ideally the USB Ethernet adapter will also have PoE so the 7 workflow is reloaded at the same time. I need this for free Wi - Fi environment.

  Thank you!

  The stream can use a USB ethernet with an OTG cable/adapter.  But you're going to encounter any problems with the charge of the end of things.  By design, the flow of charge is or host devices, but not both at the same time.  To overcome that, you would need a device like this http://plugable.com/products/ud-pro8 which basically tricks the flow by mode then by performing an external change in host mode without disconnect anything unit of charge.  It also has an own ethernet port, but the device is almost as expensive as the stream itself.

• Adding rows or cells to existing Tables in Dreamweaver CC

  Dear Sir/Madam,

  Why can't I add additional cells or columns to an existing table?

  I have a database that I've frequently updated, but I note that since I upgraded my software from Studio MX 2004 to Adobe Dreamweaver CS5.5 (try now Dreamweaver CC) and the table options (such as adding rows/columns) are not available.

  What is the best way to list the alphabetical links. Should I just list people without a table or I can use what I already designed (without having to create a new page, since it will age to enter all the data again)?

  I look forward to hearing from you soon.

  Concerning

  Suzanne

  Make sure that you are in Design view, not to live.

  The editor in Live mode does not give you the standard table options.

  EDIT: I forgot to mention, if your pages use a fluid grid, Fashion Design presentation won't be available if you use DW CC 20141, deleted Adobe Design view for GFL in this version. Here is a discussion which has a couple of workarounds: Re: is it possible to display the design view in the fluid grid pages? and here is the feature request to vote in the section ideas if you are using the latest version: provide "Design view" fluid grid Web pages

• Adding UNION Dataset on the EXISTING INTERFACE with SDK

  Nidhi

  Hello nidhi.

  Code that I wrote to do the mapping of columns has always used the action 'createTargetMapping '. See the example below:

  -----
  String tarColName = "NAME";
  String srcColName = "W_PLM_LISTENTRY_PS. ENTRYVALUE ';

  TargetColumn tarCol = inter.getTargetDataStore () .getColumn (tarColName);

  sourceExp = srcColName;
  execLoc = ExecutionLocation.WORK;

  helper.performAction (new InterfaceActionOnTargetColumnSetEnabled (tarColName, true));
  helper.createTargetMapping (dataSet, tarCol, execLoc, sourceExp);

  See if this helps.

• Added Distributed Switch, now can not access any ESX Server

  Hi guys,.

  I just completed the implementation of our first 2 ESX servers, a server vCentre added in as a virtual machine to a trial and the addition of a distributed switch to separate our traffic. During this process, I somehow picked the wrong interconnect to cross and moved VMNIC0 that running the SC and all virtual machines after the original installation.

  Now, I can't access the ESX server or server vCentre to revert back the changes I made. However, I have physical access to the servers via command line.

  Is there a relatively simple way, I can move the SC and VM' on the default vswitch? This happens when the server vCentre has been disconnected for a period of time?  I don't mind having to add the virtual machine to a vCentre at all, so remove the ESX on it will return to the way 1 vswitch and give me access again.

  I'm kinda stuck at the moment as I have ready 8 VM to start a project on but cannot access any of them!

  Thanks in advance

  Simon

  Simon,

  You must set up a group of ports "Service Console" and assign a vswif. If you follow the steps in KB http://kb.vmware.com/kb/1000266 it will show you how to do this. The service console port group is necessary for the host be observable at the customer virtual Center/vi. I have attached 2 screenshots of what esxcfg-vswitch - l and esxcfg-vswif - l should look like. The Group of ports VMotion is not necessary, just the service console.

• Questions about adding a NAS to the existing environment

  Hello

  We have an existing deployment of VI with an EMC SAN and three ESX host.  We would like to add additional storage to NAS and storage ISO tests.  To do this, we were going to set up a RHEL 5 server, as others on the forum have done and use NFS to provide a data store for ESX.  However, I have some questions that I found only partial answers on the forum.

  (1) is there a performance by adding NAS on the network of IP storage for the existing deployment of VI?  Our EMC SAN uses iSCSI to provide a storage boxes currently.  Mix iSCSI and NFS on the IP storage networking a bad idea to turn performance and stability?  Anyone done this?  Looks like a logical thing to do that many small deployments may not afford to buy company for test/development equipment and storage ISO.

  (2) what are the security implications of placing an NFS server on Red Hat-based IP storage network?  How to do this safely?  All posts of forum and documentation of security seem to focus on the need to separate the traffic of IP storage (which is clear text) to run virtual machines or physical servers.  In order to add the NAS on the network of storage, we allow access to the Red Hat server for IP storage network.

  (3) is there a way to limit the traffic on the network interface facing the storage over IP to NFS network only?  We would be two interfaces on the server Red Hat to fight against it, as our network of IP storage is not returned to the other networks in some way.  It is an isolated network by design, for security reasons.  Thus, we would need an interface connected to the stroage and one IP network that is connected to one of our management systems.

  Thank you.  I appreciate your help.

  Hello

  I can understand a problem of pure load.  What I meant is there at - it a greater load on the servers simply having to use two different storage (NFS and iSCSI) protocols?  Or is it better to use iSCSI on the storage of test/development device so that we only configuring and using a storage Protocol?

  There is some overhead in the vmkernel, but it is also to be expected.

  I think that it is at the heart of the case.  I don't use a full OS is the way to go for me.  I'm really a Windows administrator and my knowledge of Red Hat is somewhat lacking.  On this basis, it may be preferable to use a storage OS like Openfiler or NexentaStor.  Do you have an opinion on which one is more stable or efficient?

  Openfiler is Linux or FreeBSD. I still have to examine in detail, but in both cases, they are both complete BONES. Openfiler is much easier to use, however, and will be iSCSI or NFS. If it were me, and I didn't know anything about Linux, I'd use Openfiler.

  VMs allows access to the storage indirectly however ESX.

  Great, so he can participate in your existing IP storage network.  Configure web access (management) to Openfiler being on the same network as for existing SAN management application. Then have your data on the IP storage network.

  Best regards

• Added new photos to an existing building?

  How can I add new photos to an existing building.  I got 300 + photos tagged and imported.  The first version of the book used 87 and is all that now appears when I open the book.  I wish I had the 300 + original photos appear so new can be added to the existing structure.

  Make sure that the book is saved. Return to the library, then drag the other images in the book collection.

• Adding a constraint TO an existing table

  Hello
  
  I had this problem because of the existing data. My question is in my table, I want to add a unique two-column constraint, but I can't add this due to existing extensible data. And I can't do a repair data for correct extensible database since the customer is completely on these data so that we can not the decision to repair the data.
  
  As a solution, I have try this method by adding a function to check the data repeatedly before inserting data into the table. It works fine for a user, but when it come to multiple users, it does not work because users can connect to the database and can make their transactions at the same time.
  
  My question is; is there a way of oracle to add a constraint to data that may add in the future not to the old existing data?
  
  Thank you
  Darex.

  Dear Darex
  Try to understand below and check first with the same script and then apply on your data
  If you understand the logic need not go for function...

• Satellite C870-1J6 wired LAN DHCP problems

  Hi all

  Here, I have a new laptop C870-1J6, which makes my life miserable. It won't start not reliable PXE, and the network card also does not start in Windows.

  On a cold start the PXE boot Gets an address dhcp fine most of the time, but a warm reboot fails most of the time.
  In windows this NIC also does not start. After five to ten minutes, he finally gets an address from the DHCP server. Rest of the network works fine.

  No points for guessing the manufacturer of the network card, of course, there a realtek :-(
  "RTL8102E/RTL8101E PCI Express Fast Ethernet controller.
  PCI ven: 10EC, dev: 8136

  None of the solutions, or can send Toshiba somehow? because I don't think I can do a lot on the PXE problem myself.

  At first, I have to say that I m really wondering why you have problems of LAN under Windows.
  Have you noticed these LAN issues from the first day of use?
  Are you using the original pre-installed OS that you got with your laptop or a facility clean or even company?

  Maybe stupid question, but I assume that LAN is set as first boot device, right?
