1.5 mile AP to WGB connection questions

Hello all.  I am new to the forum and have just enough networking skills to be dangerous. A+ and Net+ Certs in 2000.  Self taught on my AP's and I am now finally to the point that I need help.  Bare with me.
I have 2 Cisco 1200 G AP's connecting 2 different locations.  Location A ( La ) I have a RVO82 router connected to a 50Mbit cable connection.  I have an AP setup there using a 1 Watt booster and a 24db wire grid directional antenna. Only one antenna here, the other disabled. 
At Location B  (Lb ), about 1.5 miles away, with good to excellent line of site, i have the other setup as a WGB with a 15db wire grid directional antenna with a 1 Watt booster.  Also only one antenna here, the other disabled.
WGB feeds a simple 8 port switch and in that switch i have a simple belkin wireless router setup as an AP for Lb's wireless access, which is the most used segment.  (i will usually take all the freebies i can get, lol)
The signal strenght between the two locations is -49 to -52 db, depending on what time of day I check it.
I have had this setup for a couple of years now.  I recently switched from a 3Mbit DSL connection to the 50Mbit cable connection hoping to increase my bandwidth with no luck.
When I first set this up i had a 6Mbit cable connection and it maxxed out at 5 Mbit at Lb.  I thought i would be able to add more boosters and antennas as time went on to go from half duplex to full duplex (the way i think of it is one antenna receiving and the other sending, at both locations) so that when our ISP had faster rates available, i could upgrade. I recently read somewhere on the net that it is not possible to run full duplex in the AP to WGB setup i have.  Is that true?
My main concern is increasing bandwidth on the WGB side Lb.  When i upgraded to 50Mbit, i still only max out at 5mbit at Lb.  Before i thought it was due to not being full duplex or weaker signal strengths (I've always had the 1watt booster at Lb, then i added one later to La with no benefit noticed except signal strength is better and uploads seem faster from Lb....)  I always use speedtest.net to test the speeds.  Pings from Lb to speedtest is 37ms.  Websites are pretty fast and i have been very happy at Lb.  I wanted to ask everyone here if its possible with what i have to increase bandwidth or not, or ask for other options to achieve it.  Like i said, i am happy with 5Mbit.  But i am paying for 50 and want to see how far that rabbit hole will go.  Any ideas?
And i have more questions as well, leading into multiple routers and subnets spurring from Lb with their own AP's, but that is more for play and my own curiosity...  12 years later i have a great job and finally have some play money to use a tad of that Net+ but i've forgotten most of it.
....but thats it for now as i will wait to see if everyone calls me retarded or not before posting again.  Thanks in advance ALL.

One of these days i will learn how to do that cool quote box thingy...

I have an 8 inch pigtail connected between the AP and Booster.   It converts TNC from AP side to Type N on booster side.  Then a 50 coax cable running from booster to antennaWhen i upgraded to 50Mbit, i still only max out at 5mbit at Lb.Sorry, I don't want to sound so brash, but how did you measure this?  Did you by any chance measure this from WAP to WAP of from LAN-A to LAN-B?I simply tested the speed at Location A and at location B separately with speedtest.net, with the same laptop, testing to the same server on speedtest.

  • Database connection question...

    i am using Java 1.5.0_06 and to connect to MySQL database i use Connector/J and the following code:
    try {
    Class.forName("com.mysql.jdbc.Driver");
    } catch(java.lang.ClassNotFoundException e) {
    System.err.print("Main: ClassNotFoundException: ");
    System.err.println(e.getMessage());
    return;
    try {
    con = DriverManager.getConnection(dburl);
    ps = con.prepareStatement(
    I was told i should be using a DataSource to do connection pooling and i have read over the info and downloaded jdbc2_0-stdext.jar and i am using MySQL and windows XP pro.
    the code looks like this
    Context ctx = new InitialContext();
    DataSource ds = (DataSource)ctx.lookup("jdbc/InventoryDB");
    Connection con = ds.getConnection("myUserName", "myPassword");
    then i just use con as i have already in my code.
    Can someone please point me in the right direction to get this working.
    I read this:
    A systems administrator or someone working in that capacity deploys a DataSource object. Deployment, which involves setting the DataSource object's properties and then registering it with a JNDI naming service, is generally done with a tool. As part of the registration process, the systems administrator will associate the DataSource object with a logical name. This name can be almost anything, usually being a name that describes the data source and that is easy to remember. In the example that follows, the logical name for the data source is InventoryDB . By convention, logical names for DataSource objects are in the subcontext jdbc , so the full logical name in this example is jdbc/InventoryDB .
    i have goggled but can't seem to find out exactly what i need to do next.
    I can't find the "tool" and have to be honest i am lost lol.
    can the The JDBC 2.0 Optional Package work with Java 1.5.0_06?

    i am using Java 1.5.0_06 and to connect to MySQL database i use Connector/J and the following code: i updated it to use manual connection pooling like so:
    final String dburl = "jdbc:mysql://localhost/......";
    Connection con = null;
    try {
    Class.forName("com.mysql.jdbc.Driver");
    } catch(java.lang.ClassNotFoundException e) {
    System.err.print("Main: ClassNotFoundException: ");
    System.err.println(e.getMessage());
    return;
    try {
    DataSource dataSource = setupDataSource(dburl);
    con = dataSource.getConnection();
    con.close();
    public static DataSource setupDataSource(String connectURI) {
    ObjectPool connectionPool = new GenericObjectPool(null);
    ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectURI,null);
    PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory,connectionPool,null,null,false,true);
    PoolingDataSource dataSource = new PoolingDataSource(connectionPool);
    return dataSource;
    so i compiled and ran it and it worked no problem but my question is that this is a server that does some db work upon starting and then waits for clients like so:
    while (listening)
         new PSMultiServerThread(serverSocket.accept()).start();
    so once i am in PSMultiServerThread what exactly do i need to do?
    i know i don't need to do this again:
    Class.forName("com.mysql.jdbc.Driver");
    but do i need to do this again:
    DataSource dataSource = setupDataSource(dburl);
    i geuss i have to to declare the variable lol.
    and do i include this code in the PSMultiServerThread
    public static DataSource setupDataSource(String connectURI) {
    ObjectPool connectionPool = new GenericObjectPool(null);
    ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectURI,null);
    PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory,connectionPool,null,null,false,true);
    PoolingDataSource dataSource = new PoolingDataSource(connectionPool);
    return dataSource;

  • Multiple DB connection question.

    I have a MDB that currently processes a message and updates a Oracle DB say Database A. Now we want that MDB to check some flags on a different Oracle database instance, say Database B before it updates the Database A.
    Basically, the during the processing of a message the MDB has to access Database A, Database B and Database A again in that order. My question is whatever I am trying to do is reccommended? Since I need connection to Database A again after I do some woek with Database B, can I still keep that connection around or do I have to close that right away?
    I am using wls 8.1.
    Any suggestions?
    Thanks
    JB

    <p>The short answer is that you can keep both connections around at the same time, without any issues. Just be careful with any cleanup where you close connections, and make sure that both get dealt with regardless of any exceptions that might occur.</p>
    <p>But depending on the number of MDBs in your configured pool, it might be a more efficient use of database connections to create a smaller pool of stateless session beans to hold those database connections and expose utility methods for the queries (which could use prepared statements)</p>

  • Basic XI 3.0 to R/3 4.6c connectivity question

    Greetings XI gurus,
      I'm trying to setup & use a connection to an R/3 4.6c server from XI 3.0 to be used to call over & run one or more RFC's. I've created regular R/3 SM59 settings in both for a connection between the 4.6c server and the XI box.
      However, in the system landscape, when I try to create a technical system, I have trouble on the last screen where you select the product. I try to use "SAP R/3 4.6c" and it says that there are no components found for that product.
    1) Does anyone know what component it is looking for?
    2) How do I import that component?
      Thanks,
    Doug -

    Jin & Michael,
      Thank you for your prompt replies.
    Yes I can see the "SAP R/3 4.6C" product.
    I'll have to get authorization for the RZ70.
      One of the members of our BASIS team has contacted a seemingly experienced old collegue who claims to know how to do this.
      So... for now anyway... I'll close this question
      Thank you both for your help.

  • 970a-g46 am3+ cable connection questions

    Hi all,
    I'm a first time computer builder and am in the process of building my own rig. I have MSI AMD 970a-g46 am3+ mobo and cool master elite 431 case.
    1) I can't seem to find where on the mobo to connect the speaker for the post beep test. I've tried to look through the manual and watch videos but all the videos skip ahead of the internal cable connections to them being done.
    2)the cool master 431 case comes with HD and AC 970 audio, which do I use with the MSI AMD 970a-g46 mobo? I think its the HD from what I've seen/read in videos.
    3)I would like to do the test boot with the mobo, the gpu, psu on the monitor and post beep before mounting to make sure I connected it all correctly at least once but I don't know where to connect the speaker (question1). Also I don't know where to "short" the mobo before connecting the psu and plugging it in to "turn on" the mobo for the test. I saw a video by newegg of building a computer where he did the same.
    That's all the questions at the moment since I'm taking a break. Any help would be majorly appreciated. Thanks.

    ok attached the Front panel connectors diagram below! just find the missing pins and count to locate pins! (the name of the headers should be marked JFP1 and JFP2)

    connect the HD audio one not the AC97 from your case to the audio header!

    and as for shorting the board to power it up to test it works thats on JFP1 on pins 6+8 just short those 2 and it should start up!
    if you do start it outside your case use a piece of plain cardboard under the mother board to isolate it from shorting out on anything!

  • ACE 4710 - show stats connection questions

    Hi,
    I have three questions regarding the "show stats connection" command in the ACE 4710:
    1. What is the criteria for a connection to be added to the "Total Connections Failed" counter?
    2. What is the criteria for a connection to be added to the "Total Connections Timed-out" counter?
    3. Is there a command to get more information why the connection was failed or timed-out (e.g. to/from which IP, url accessed etc.)?
    Thanks in advance for your help!
    Best regards,
    Harry

    Harry,
    a connection failed if the server did not respond or resonded with a RST.
    As long as the connection gets establised, it is counted as a success.
    The connection timeout counter is incremented when the connection is idle for the configured timeout value or for L7 connections if it does not complete the 3-way handshale within the embryonic timeout interval.
    Since this is clear why those counters are incrementing, the only way to get more information is to capture a sniffer trace to verify if the conditions above are met.
    Gilles.

  • Transporter - Basic installation and connection questions

    We have never used or installed the Transporter before.  We are currently using Tidal 5.3x and are upgrading a sandbox environment to 6.2.  I have looked at all the transporter documentation I can find and am still missing some very basic questions - plus I cannot get the "help" option in transporter to work.
    WHERE do you install the Transporter and why?  CM Server?  Master Server?  Desktop?  If it is on a server, then does the user that runs it need to remote the server in order to user transporter?
    I have attempted to install on each of the above, but cannot establish a connection.  When I click "test" I get error "Failed to Connect [Login failure with responseCode [404]]What should I be entering in each of the following Connections fields?  My comments indicate what I have assumed/attempted to enter and received the error above.
    Connection name  - just a given name to a connection? aka TESSandboxMaster
    Server Name  - what server?  master?  Is there a specific format this needs to be in?
    DSP/Plug in name - I found a dsp file on my CM Server named TES-6.0.dsp - should I put TES-6.0 here?
    User - network user that is a Super user in Tidal?  aka networkname\superuser?
    pwd - windows pwd for that user?
    Thank you for any help you can provide.

    Hi Patricia,
    1. The Transporter is installed on the Client Manager - the CM is essentially a web server to handle client requests, perform sacmd commands, and utility for transporting jobs from one environment to another. A Tidal user would have to be granted rights to Move Jobs to Production, and I believe Tidal user has to be able to sign on to the CM as well.
    2. I've reviewed an older copy of the transporter user guide 6.1 provides instructions on how to complete those fields:
    To create a connection: (on page 32)
     In the Connection Name field, enter the name for the connection file.
    In the Server Name field, enter the name of the Client Manager machine.
    In the DSP/Plugin Name field, enter the master instance name.
    The master instance name is the TES DSP or Plugin name. This is displayed from the Web UI in the Master Status pane.
    In the Server Port field, enter the listening Web Service port used by the Tidal Web Client. The default is 8080 for non-secured connections and 8443 for secured connections.
    In the User and Password fields, enter a valid Enterprise Scheduler user name and password.
    Select the Secure HTTP option if you want to connect securely through the HTTPS protocol.
    This option is enabled only if Transporter has been configured for secure
    connections. Figure 8 is an example of Transporter not configured for secure
    connections.

  • Z87-G45 Fan Connection Questions

    Greetings,
    I wanted to ask about connecting my Corsair liquid cooler.  I'm using 2 radiator fans in a push-pull config, plus the cooler itself needs power.  The Z87-G45 has 2 cpu fan connectors.
    My first question is am I going to get fan control from this mobo?  All my fans and cooler cables are 3-pin.  I was given the impression that you might need 4-pin fans for variable fan speed control.  Is that true?
    If I am somehow going to get fan control from the mobo, I'd appreciate some advice on what goes where.  Should I hook up the cooler power and one of the radiator fans to the CPU fan connectors and then the other radiator fan to a sys fan connector?  Or would it better to have the cooler power on a sys fan connector?  Better yet, is it safe to use a Y-connector for both of the radiator fans.  I can't get a clear read on whether or not there is enough power for that and also whether it might screw up the BIOS readings for fan control (if that's a factor).  I'm also one connector short for all the fans I want to run, so a Y-connector would be ideal.  The 2 radiator fans are identical (Corsair AF120 - 12v/0.40a).  I've read people write they *think* the max amp for each connector is 1.0, but I can't find anything definitive (it's not in manual).
    If you're confident about any of this, I would appreciate your advice.
    Thanks,
    Bobby

    Thanks for replying to one of my posts yet again Nichrome.  You are an invaluable resource for this forum.
    I did a double-check, and the Corsair fans are 3 pin.  It's a shame; I wish I had studied this b4 I bought them.  They are the loudest fans in my system.  4 pin fans, surprisingly, still seem to be very much the exception.  Doing a search on Newegg for 4 pin fans, most of them, where I could see a picture of the plug, were of the old power supply molex variety.
    Am I right to believe that the fan control for the CPU fan headers would be based on the CPU temp and the Sys fan headers would be based on either the mobo temp or the general temp of the air in the case?  That will confirm for me if it's a bad idea to hook up the radiator fans to the Sys fan headers.
    Thanks,
    Bobby

  • Jampack and keyboard connection questions

    2 questions:
    1. I have just bought GB Jampack (the one with lots of extra loops), but can't seem to notice any difference. How do I know that the disc has downloaded OK? Can't remember how many loops were there in the first place!
    2. I'm trying to connect an Roland SK-50 Soundcanvas keyboard. Do I need some sort of interface or drivers before it will work?
    Very basic questions, I know, but hey, that's what this discussion group is for isn't it?!
    Regards
    Mark

    How do I know that the disc has downloaded OK?
    If you bought the JamPack DVD you didn't download anything. Did you run the installer on the JamPack DVD?
    To see just loops from your JamPack disc, open the Loop Browser and click on the top bar where it likely says "Loops" with a double arrow, and select "JamPack 1". Then only loops from the JamPack will show in the loop browser.
    Re: the Keyboard
    What kind of conection doesd it have? All I could find was " complete with direct Mac or PC connection" and "Connections: MIDI In, MIDI Out, MIDI Thru, Line In (LR), Line Out (LR), Computer port, and 1/8" stereo headphones jack."
    "Computer Port" isn't very specific. Is it a USB connection? You might need to find a driver for it. Does the Manual say anything about installing software to make it work?

  • IPad - SUP connection questions

    The import works perfectly on device but I'd like to have more control on that. here are different questions I'm asking myself concerning that :
    1) I'd like to check if the connectivity is ok before deleting the local DB ?
           When using the code above the locale db is deleted before launching SUPMessageClient start. It is recommended to do that in the documentation BUT, if the connection does not succeed, the locale db is empty and the iPAd app can not be used anymore. IS there a way to check connectivity before launching the sync process ?
    2) On the other hand, I've got a method creating new elements and I'm calling submitPending, but nothing happens in terms of update to the server. Should I do a subscribe to the package each time I want to interact with the remote SAP server ?

    Hi again,
    yes, you can search for records in the local (iPad) database. Contrary to Apple's core data you don't have to use predictives but you have to define the query for a database search on the SUP. When modelling the attributes of your MBO in the Unwired Workspace, you can define the syntax of the query on right-most tabsheet (named "Object Queries"). The "findAll" and "findByPrimaryKey" query are the 2 default ones.
    For instance, if you have a MBO called "TimeRecord", a query could look like:
    SELECT x.* FROM TimeRecord x
    WHERE x.WBS_ELEMENT = :wbsNumber
    AND x.WORKDATE = :Workdate
    where you have to define the parameters wbsNumber and Workdate which are mapped to the MBO-fields WBS_ELEMENT and WORKDATE respectively. The name of the query could be LookForTimerec
    In xCode you can now simply type:
    objTimeRecordList* timerecordlist = [objTimeRecord LookForTimerec:wbsElement withWorkdate:workDate];
    where wbsElement and workDate are Objective-C variables (which you have to define).
    objTimerecord is the class-Name of the MBO and objTimeRecordList is the SUPObjectList of Timerecords: both objects will be generated by SUP and are imported with the source code into your xCode project.
    During runtime, the variables wbsElement and workDate will be mapped onto the query-parameters wbsNumber and Workdate.
    Best regards

  • SP06 API Connection Questions

    Hello API Experts,
    I have a few questions related to connections to MDM using the API presented with SP06.  SP06 introduced new options for connections via classes in mdm.sessions package.  Which connection types are preferred for a java web services environment, using classes in mdm.sessions package or mdm.net package? What is the reasoning behind your choice?
    When I create a UserSessionContext I notice that 2 connections are created ( I watch the connections in MDM Console as I'm debugging my java app ).  When I want to get rid of these connections I do a releaseSessions( ) and destroySessions( ) call.  The connections disappear from MDM console (that's good) but on my java console window in eclipse I get two messages printed from the mdm.logging.MdmLogger class:
    SEVERE: Can not find session for release. Session context: '< my connection info >'
    SEVERE: Can not find session for destroy. Session context: '< my connection info >'
    Is this really a problem since the connections seem to disappear from the Console?
    Finally, what are the differences between releaseSessions and destroySessions and would one ever want to releaseSessions and not destroySessions with the intention of picking them up again later and if so, how would you pick them up again at that later time or would the API just hand them back to you when you later ask for a new __SessionContext?
    Thanks,
    Mark

    Hi Mark,
    The new classes introduced in the com.sap.mdm.session package were introduced in order to make session creation less painful for the software developer.  It is up to you, though to choose how you wish to create a connection to an MDM server.
    The function releaseSession marks a s session as available for destruction. DestroySession immediately calls for destruction of the session.  So you should use one of these functions, but not both of them.
    Regards,
    Walter

  • 4 Nano Connection Questions

    I have an old 20GB iPod w/dock connector (the one with the 4 buttons above the click wheel). The dock came with both a USB 2.0 cable and a firewire cable. I've been using the firewire cable, although I think I can find the USB cable that came with it.
    I just got a new 3rd gen Nano. I haven't opened the box yet (it's a gift), but I understand that it comes with a USB 2.0 cable.
    Questions:
    1. Will the Nano fit in the old dock?
    2. Can the Nano connect using firewire rather than USB, and if so, will it charge (the old iPod charges OK through the firewire connection)?
    3. If a firewire connection will work, but the Nano won't fit in the dock, will the old firewire cable connect to the Nano?
    4. The Nano specs say "USB 2.0". Other than slower transfer speed, will Nano work with a USB 1.0 port or is a USB 2.0 port required?

    I think I've found the answer to one of my questions.
    The firewire-to-dock cable will work to charge Nano, but not for sync. That suggests that the firewall cable will connect directly to Nano, and probably also that the Nano will fit in the dock, but that can be easily determined once I unpack Nano.

  • RV042 VPN Connection Questions

    Hello,
    I have successfully connected two RV042s to establish a VPN gateway to VPN gateway connection. I have the follow questions, please comment:
    1. I would like to keep the VPN tunnel connection time indefinite. Is it sufficient by checking the "Keep-Alive" box on the VPN -> Gateway To Gateway -> Advance page? Or, I have to ping the RV042 periodically?
    2. Do the "Phase 1/Phase 2 SA Life Time" (on VPN -> Gateway To Gateway page) settings have any impact on keeping the VPN connection time indefinite? What are the optimal values for them?
    3. Is there an API, command, or script to replace a manual clicking on the "CONNECT" button to establish the VPN tunnel from the VPN -> Summary page? Or, is there a way to accomplish this at power up?
    4. Is there a way to establish a VPN tunnel without going through login and clicking the "CONNECT" button? (Auto connect at power up?)
    Thank you in advance for the comments.
    Steve

    Hi, Mike,
    I did not do any extensive testings on the RV042s, but I did the following things to my RV042s:
    1. Enabled the "Keep-Alive" feature  (see Administration Guide, page 128),
    2. Enabled the "Dead Peer Detection" feature and set the interval to 10 seconds. (see Administration Guide, page 129).
    Make sure you save the changes.
    These features are available below the "Advanced" button under the VPN selection. I hope this help.
    You can power down the router or disconnect the network to verify the result. The VPN tunnel should be re-established and stay connected.

  • Datasources connection questions

    hi all
    my question is about How the connections stored in a Jndi server datasource pool are managed.
    For example, I'm developing a J2EE application with Ejbs and Datasources, etc. I saw that when I want to retrieve a connection from datasource to work on it I need do something like this:
    For example to retrieve a datasource connection:
    Hashtable jndiProps = new Hashtable();
    jndiProps.put(Context.INITIAL_CONTEXT_FACTORY,...);
    jndiProps.put(Context.PROVIDER_URL, ...);
    Context context = new InitialContext(jndiProps);
    DataSource ds = (DataSource) context.lookup("jdbc/MyDatasource");
    Connection con = ds.getConnection();
    ...I know in this case that the server manages a datasource connection pool, etc
    My question is when a get a connection from the Datasource pool of my app server. do I need to release the connection with some special method when I finish with it (in order to return it to the pool) or it doesn't matter ?
    thanks in advance

    If I have three prepared statements right in a row with nothing in between should I close the connection after each one and then get it again?
    Seems like I would be just as well off to just get the conn once do the 3 things then close it.
    and in spots I might actually be doing something as i step through the first result set so can i use conn.preparedStatement() in the loop many times without getting the connection and closing each time through the loop?
    i of course close all PS and RS and use diff PS2 and RS2 in the loop so i 'm just talking about keeping the conn open while (RS.next()) and use it multiple times to conn.preparedStatement() inside the loop?
    or should i use 2 connections lol and open conn1 and then in loop use conn2 and close it each time around the loop and then close conn1 when i exit the loop?
