E4200 firmware - 1. Your experiences? 2. Performance diffs. between 1.0.00 and 1.0.01?

I would like to hear from other E4200 owners regarding performance comparisons between the two E4200 firmwares.
Questions:
1. Is the new one any more reliable?
(I have not had any reliability issues with the original firmware which I am still using on my current E4200).
2. Does it perform better with one or the other (firmware)?
3. Any other observations you want to share regarding any differences in performance between the two.
Thanks in advance.
Hopefully this thread and the feedback it generates will help E4200 owners compare notes with one another.

Did you call tech support to figure out if your settings (channel etc.) could / should be adjusted?
Sorry it did not work for you yet, but as far as your comments are concerned, I think the following comparison tests shed some light on the reality of the performance of the two.
The E4200 crushed the Apple in the smallnetbuilder.com 'throughput vs. location' 2.4 GHz wireless tests, especially in anything but the closest two locations (look at the numbers for locations E and F):
http://www.smallnetbuilder.com/lanwan/router-charts/graph/58-2_4-ghz-dn/952-airport-extreme-base-sta...
Just posting this test link to add some perspective since people googling might stumble onto your comments and take them at face value.

  • Diff between the Start routine and Update rules?

    Hi Gurus
    Diff between the Start routine and Update rules?
    Thanks in advance
    Raj

    Hi,
    Routines are like conditions or business rules that could be applied to filter the data while entering the BW system or could be used to apply certain conditions on the info objects itself.Update rule level you manipulate your data and  write your start routine.
    There are 4 types of routines
    1. Start routine- Could be used at two levels (transfer rule level and the Update rule level)
    This Start routine written at the transfer rule level helps filter the necessary data coming from the source system.
    For Example: If you decide to extract data that contain only quantity greater than 500 , then you could specify the Start rouitne to achieve this.
    The Start routine at the Update rule level provides similar functionality but at this point it helps direct specific data to 
    different data targets.  For Example: If there 3 data targets being fed from the Infosource, you may want to apply some condition to each data target, like send year 2000 data ti Data target1, 2001 to data target 2 and so on.  This can be achieved by using Start routine at the Update rule level
    2. Transfer Routine: This feature is available at the transfer rule levels
    While performing the transfer rules operation, there are 4 features available to the developers to create business rules on top pf the Infoobjects.
    1. You could do a one to one mappping of the Infoobject
    2. Provide a constant value
    3. Include a formula
    4. Write an ABAP routine.
    These 4 options refers to the transfer routine
    3. Update Routine:
    The limitations of just having 4 options in the transfer routine is overcome at the update rule level. There are various other 
    sophisticated features avaialable apart from the 4 options mentioned above. These business rules could be specified pertaining to each data target.
    4. Conversion Routine: It provides functionality to do Currency and unit conversion.
    Regards.

  • Diff between LIS,LO,COPA and Genric extarctions.

    HI,
    Can anyone brief me the diff between LIS,LO,COPA and Genric extarctions.

    Hi,
    LIS:
    The Logistics Information System (LIS) is a data warehouse used for reporting in all of the application areas in Logistics (LO).
    Typically, the data stored in the LIS is an aggregated subset of the data stored for your transactions. For example, you would not usually find the full information stored with all sales order documents. Instead, you would find key field values such as order quantities, total order costs, and item costs. These values could also be stored according to business entities such as sales organization, distribution channel, division, and sold-to party. Similarly, the document detail for all material movements is typically not stored, but the aggregated stock quantities and values are stored based on plant and material.
    COPA:
    Profitability Analysis (PA) is an integrated component in the SAP R/3 system.
    All of the data related to profitability from the other SAP R/3 applications is mapped in CO-PA in accordance with the corresponding business transactions.
    This allows you to transfer into CO-PA billing document data from SD, cost object costs from CO-PC, and overall costs from overall cost controlling.
    CO-PA collects all of the OLTP data for calculating contribution margins (sales, cost of sales, overhead costs)
    CO-PA also has powerful reporting tools and planning functions
    Generic Extractors:
    When should you use generic extractors?
    Business Content does not contain a DataSource for your application.
    The application does not feature its own generic delta extraction method
    You are using your own programs in SAP R/3 to populate the tables
    The tools for generic data extraction can be used to generate an extractor for all applications.

    hi,
    Physical inventory number
    Specify a number or name under which several inventory documents can be grouped together for improved processing
    Reference Number for Physical Inventory
    Specify the number of a document outside the system that relates to an inventory transaction.
    means if you are using MI01 then you have to maintain the data in mi04  . but you are using mi09 no need to maintain the datad directly you are go through with mi07 for posting the differences.

  • Diff between at line selection and HIDE technique

    hi all,
           wht is the diff between at-line-selection and HIDE technique.
            wht r code instructor
            wht is extended testing
            how can we find selected error records in session                          method ex:-if there r errors in 4th 9th 13th record.
    tthnx in advance

    HIDE
    Syntax
    HIDE dobj.
    Effect
    This statement stores - in the current list level - the content of the variable dobj together with the current list line whose line number is contained in sy-linno. The data type of the variables dobj must be flat and no field symbols can be specified that point to rows of internal tables, and no class attributes can be specified. The stored values can be read as follows:
    For each user action in a displayed screen list that leads to a list result, all the row values stored using HIDE - that is, the row on which the screen cursor is positioned at the time of the event - are assigned to the respective variables.
    If a list row of an arbitrary list level is read or modified using the statements READ LINE or MODIFY LINE, all the values of this row stored using HIDE are assigned to the respective variables.
    Notes
    The HIDE statement works independently of whether the list cursor was set. In particular, variables for empty list rows can be stored - that is, rows in which the list cursor was positioned using statements like SKIP.
    The HIDE statement should be executed immediately at the statement that has set the list cursor in the row.
    Outside of classes, constants and literals that cannot be read in list results and in the statement READ LINE can be specified for dobj outside of classes.
    Example
    Storing square numbers and cubic numbers for a list of numbers. The example shows that arbitrary variables can be stored independently of row content. In the real situation, one would more likely store only the number and execute the calculation, when required, in the the event block for AT LINE-SELECTION.
    REPORT ...
    DATA: square TYPE i,
          cube   TYPE i.
    START-OF-SELECTION.
      FORMAT HOTSPOT.
      DO 10 TIMES.
        square = sy-index ** 2.
        cube   = sy-index ** 3.
        WRITE / sy-index.
        HIDE: square, cube.
      ENDDO.
    AT LINE-SELECTION.
      WRITE: square, cube.
    AT LINE-SELECTION
    Syntax
    AT LINE-SELECTION.
    Effect
    This statement defines an event block whose event is triggered by the ABAP runtime environment during the display of a screen list - provided the scren cursor is on a list line and you select a function using the function code PICK. Through the definition of this event block, the standard list status is automatically enhanced in such a way that the function code F2 and, with it, the double-click mouse function is linked up to the function code PICK.
    Note
    If the function key F2 is linked with a function code different than PICK, each double click will trigger its even, usually AT USER-COMMAND, and not AT LINE-SELECTION.
    Example
    This program works with the standard list status. A line selection with the left mouse key causes the event AT LINE-SELECTION and creates details lists.
    REPORT demo_at_line_selection.
    START-OF-SELECTION.
      WRITE 'Click me!' COLOR = 5 HOTSPOT.
    AT LINE-SELECTION.
      WRITE: / 'You clicked list', sy-listi,
             / 'You are on list',  sy-lsind.
      IF sy-lsind < 20.
        SKIP.
        WRITE: 'More ...' COLOR = 5 HOTSPOT.
      ENDIF.
    Thanks,

  • Diff between Item Amount Check and Stochastic Block

    Hi,
    what's the diff between Item Amount Check and Stochastic Block in LIV??

    Item Amount Check
    The system calculates the sum of the value invoiced so far for the
    order item and the value of the current invoice and compares it with
    the value limit of the purchase order. It then compares the
    difference with the upper percentage and absolute tolerances
    defined.
    Stochastic Block
    You can block all invoices to check them again through Stochastic block automatically. If the stochastic block is active and you post an invoice that is not subject to any other blocking reason, it can be selected for blocking.
    Please make a note that- A stochastic block is not set at item level, but for the whole invoice. If a stochastic block is set when you post the invoice, the system automatically sets an R in the field Payment block in the document header data; there is no blocking indicator in the individual items.
    In Customizing for Invoice Verification, you can define:
    -If stochastic blocking is active
    -The degree of probability of a block. You set a threshold value and a percentage for this.
    If you enter a threshold value of zero and a percentage of 99.9%, all invoices would then be blocked automatically.

  • Diff between R/3 ECC5 and ECC6

    Dear All,

    May be there are lot of differences but broadly:
    the Inclusion of Netweaver Components happened from 4.t to ECC5.0 and ECC 6.0
    In ECC 5.0 the component versions of netweaver are of different versions but in ECC6.0 all componet versions of netweaver are same and latest.
    Unicode is another important thing for ECC6.0 and 5.0
    AP ECC 5.0 is part of SAP ERP 2004---- which runs on SAP NetWeaver 2004
    SAP ECC 6.0 is part of SAP ERP 2005 (mySAP 2005)--- runs on SAP NetWeaver 2004S
    Main difference is application components and availability of new features.
    for new features/changes in core modules like FI, MM etc.. e.g GL function is new in ECC 6.0..

  • Diff between create proc is and as

    Dear all,
    I want to know diff between "create procedure is" and "create procedure as".I tried searching on net but didnt find please dont mind.
    Regards

    As Justin says, there's no difference.
    Except the semantics of the English language. We would typically say, "do this action AS follows..." and "this thing IS..." which in terms of PL/SQL would translate as... e.g.
    CREATE OR REPLACE PROCEDURE myproc AS...... where the action is the creating or replacing of the procedure...
    and
    PROCEDURE myproc IS...... where the procedure is just being defined, as it would be in a package.
    It makes not difference to PL/SQL, but I like to write it so it reads correctly for me when I do it.

  • Performance Difference Between Dual 2.7 and Quad, and Logic Pro

    I used to have a G5 DP 2.7 before it went bad and Apple offered me a Quad in exchange. I'd like to understand some details of the specs between these two computers and how they might translate with respect to running Logic Pro (which I'll get to in a minute)...
    Listed below are the specs which I believe illustrate the significant differences between these two machines (this info is based on info gleaned from Macworld, since the specific specs of the DP 2.7 no longer appear on Apple's website):
    Dual 2.7
    (2x) 2.7 GHz, cache = 512K per processor, frontside bus speed = 1.35 GHz per processor
    Quad
    (4x) 2.5 GHz, cache = 2MB on-chip L2 per chip, frontside bus speed = 1.25 GHz per processor
    So here's the link with Logic: it's become apparent of late that Logic Pro is not able to fully utilize the processing power of all 4 cores in the Quad. Reports are that performance tops out at 50% per processor, resulting in approx. 200% possible processing usage from the 4 cores in the Quad.
    However, such a limitation in processor usage wasn't present in the DP 2.7.
    So based on the information I've learned so far, it seems that the Quad and the DP 2.7 are almost equivalent in terms of processing power when running Logic Pro. Now, this is what I'm surmising, but, is this actually the case? At the end of the day, I'd like to know if the Quad indeed a more powerful computer than the DP 2.7 when running Logic Pro, or, did my exchange of DP 2.7 for the Quad constitute a "downgrade" of any proportion?

    The only logical answer to Why Intels do and PPC don't is:
    Apple want everybody to transition to their Intel boxes. The only way to do this is offer better performance in software tweaks for one system over the another, which begs the question what else will Apple do to software for PPC owners?
    Having bought a Mac Pro, primerily for testing out certain software apz under Rosetta, I did a real time test between my 8GB RAM G5 Quad and my stock Mac Pro upgraded to 2GB RAM, batch processing 204 Canon 1DsMKII RAW files into 16-Bitt TIFFs. I put a thread on the Mac Pro forum here:
    http://discussions.apple.com/thread.jspa?threadID=627916&tstart=15
    I so wanted my Quad to squash the Intel invaded Mac, but results speak for themselves. The Mac Pro flattened the G5 Quad by over 23 minutes (it worked out as 1.7 times faster than the G5Quad).
    If that's how it performs with 2GB RAM it's gonna really fly when I max it out. So, for musicians, I would imagine with the Quad core support for Intel Macs in Logic 7.2.2 makes a fairly straight forward decision. . .buy a Mac Pro and sell your PowerMac. More time composing less time waiting for renders (never used music software so if it doesn't render your composition place whatever it does do into the 'renders' slot )
    P.S I hated, really hated having to say the Mac Pro toasted my G5 Quad, I so wanted the Intel to fall flat on it's aluminium as$, but it didn't. It's a quick machine. A very quick machine which toasted my Quad in real time tests using a universal Pro app from a 3rd Party (who would have no incentive to dumb down the PPC version as they sell their product to Windows, PPC OS X and Intel OS X)

  • Diff. between Mass Object Controlling and Single Object Controlling

    Hi,
    Can anybody tell me what is the diff. between Mass object and single object controlling.
    I came to know that Mass Object creates the profitable segment where as single object controlling creates the internal order.
    Can anyboyd brief with exampl and what u ment by internal order..

    HI Lucas...
      here is about the three things U asked:
    let us take an example:
    Ur company is to buy spare parts of computer, assemble them with the help of ur employees and sell it finally.
    You know, you planned that ur total spare parts cost you 15000/- by enquiring in the market , labor costs is 5000/- per pc (acc. to employee wages u give to the labor)
    so, ur total computer cost is 20,000/- & u wanna sell it for 25,000/-
    Here, <b>Preliminary costing</b> per pc = 20,000/-
    But, unexpectedly, on the day u r bought parts, one part rate has gone up by 1,000/- &
    U assembled the computer & sold to your customer.
    ur computer cost has come to 21,000. (15,000/- + 1,000/- + 5,000/-)
    This is called <b>Simultanous costing</b>
    This costing is done in SAP using production order confirmation.
    at the month end(called period end closing in SAP) ur employee unexpectedly demanded to give 7000/- per pc for the pcs that were sold last month. You need that employee & u paid him accordingly. This cost u hav come to know only at the period end.
    so the <b>Final period costing</b> is 23,000/- (15,000/- + 1,000/- + 7,000/- )
    This is done in SAP using production order settlement.
    Do assign points if it is helpful
