• WRT54GS - wireless performance problem

  Dear someone

  I am currently having performance problems with my WRT54GSv1.1

  Just received my new internet connection to 30Mbit. Unfortunately, I am not able to download at that speed. If I connect via one of the linksys router's ethernet ports, I'm a happy person, but using the wireless makes me a little less happy.

  Wireless: 15Mbit/s

  Through the cable: 27Mbit/s

  Network information:

  The distance between the router and the computer laptop 3-4 meters

  Linksys WRT54GSv1.1 - Firmware Version: v4.71.4

  Network wireless - g only mode

  TV - 6 (because all the surrounding neighbor use 10-11, I noticed using Cain Abel & wireless discovered 4.9.29)

  Security: WPA2-Personal (TKIP + AES)

  All other settings are default (just reset to the factory settings).

  Laptop:

  Windows Vista Business SP1 32-bit

  Intel PRO/Wireless 3945ABG (installed the latest drivers from the website of intel, default settings)

  When you check the diagnostic of Intel tools, it tells me the link is 54 megabits and pushes meter packages of 54 megabits, while all lower speeds remain the same.

  More diagnostic information:

  Percent missed beacons: 0

  Percent transmit errors: 18

  Current Tx power: ~ 32 mW (100%)

  Supported power levels: 1.0 mW - 32.0 mW.

  Hope someone can help me here.

  Thanks in advance!

  Kind regards

  Although wireless g "connects" to 54 Mbit/s, the maximum possible wireless "data rate" (in ideal laboratory conditions) is only about 20 to 25 Mbit/s.  Unfortunately, the phrase "in ideal laboratory conditions" generally excludes home intrusion!

  The aerial transmission for wireless connections is higher than for wired connections.   Thus, most individuals find that their Wi - Fi connection works at 50% to 70% of their speed of wired (LAN).  Your wired LAN being 27 Mbps connection speed, your 15 Mbps wireless speed is within normal limits.

  You might be able to tweak a bit more speed from your wireless network by optimizing all your wireless settings.  Here are a few suggestions:

  I guess you want actually to WPA2 encryption.  If so, set to AES only.   When you set the router to TKIP and AES, you actually tell the router to accept a WPA or WPA2 connection.

  Also, give your network a unique SSID. Do not use "linksys". If you use "linksys", you can try to connect the router to your neighbor. Also set 'SSID Broadcast' to 'active '. This will help your computer to find and lock on the signal from your router.

  Bad wireless connections are often caused by interference from other 2.4 GHz devices. This includes cordless phones, baby monitor wireless, microwave ovens, wireless mice and keyboards, wireless speakers and wireless network from your neighbor. In rare cases, Bluetooth devices can interfere. Even some 5 + GHz phones also use the 2.4 Ghz band. disconnect these devices and see if that solves your problem.

  In your router, try another channel. There are 11 channels in the band of 2.4 GHz channel 1, 6 or 11 generally works better. Discover your neighbors and see what channel they use. Because the channels overlap, try to stay at least + 5 or - 5 channels of your more powerful neighbors. For example, if you have a powerful neighbour on channel 9, try any channel 1 to 4.

  Also, try putting the router about 4 to 6 feet above the ground in an open area. Do not place behind your screen or other computer equipment or speakers. The antenna must be vertical.

  In addition, in the computer, go to your wireless software and go to 'Favorite networks' (sometimes called 'Profiles'). There are probably a few listed networks. Remove any network called "linksys". Also remove any network that you don't recognize or that you no longer use. If your current network is not listed, enter its information (SSID, encryption (if any) and key (if any)). Select your current network and make your network by default, then set it to auto login. You may need to go to 'settings' to do this, or you may need to right click on your network and select 'Properties' or 'settings '.

  If you continue to have problems, try the following:

  For wireless g routers, try setting the "baud rate" at 54 Mbps.

  If you still have problems, download and install the latest firmware for your router. After an update of the firmware, you must reset the default router, and then configure the router again from scratch. If you have saved a router configuration file, DO NOT use it.

  I hope this helps.

• I'm having a problem with a sound used for Norton ccSvcHst.exe process. And perhaps dwm.exe

  I'm having a problem with a sound used for Norton ccSvcHst.exe process. I have all the dates of the last mounted and I roughly 1 000 000 errors page an hour and the hard drive of my computer is crazy with me doing nothing. Norton has been included in the software package supplied with the computer. so I hope that support you. What can I do to calm my computer runs to stop this service... I have also about 500 000 for the service dwm.exe. What could cause this?

  Hi dude, on average

  A. from when what happens?

  B. recent changes made on your computer?

  C. you get any error message?

  First of all, I suggest you to uninstall and reinstall Norton using the Norton Utilities disk and check if the problem persists.

  Second, you may have to perform an auditor of the system files on your computer in order to replace the files corrupted on your computer.

  Open an elevated command prompt. To do this, click Start, click programs, accessories principally made, right-click Guest, and then click Run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click on allow.

  Type the following command and press ENTER: sfc/scannow

  The sfc/scannow command. analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

• ViewObject range Paging performance problem

  Hi all

  I am facing a performance problem with the implementation of an obligation to programmatically add a number of extra where the parameters of the clause (using bind) variable in combination with range paging.

  My code looks like this

  ...
  
  ApplicationModule am = Configuration.createRootApplicationModule("services.DossierAM", "DossierAMLocal");
  ViewObject vo = am.findViewObject("DossierListView");
  
  // apply programmatic view criteria
  ViewCriteria vc = vo.createViewCriteria();
  ViewCriteriaRow vcr = vc.createViewCriteriaRow();
  vcr.setAttribute("Reference", "15/%");
  vc.addElement(vcr);
  vo.applyViewCriteria(vc, true);
  
  
  // enable range paging
  vo.setAccessMode(RowSet.RANGE_PAGING);
  vo.setIterMode(RowIterator.ITER_MODE_LAST_PAGE_PARTIAL);
  vo.setRangeSize(50);
  vo.scrollToRangePage(5); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled
  // vo.scrollToRange(250); // Cause a java.sql.SQLException: Parameter IN or OUT missing for index.....debugging learned that the :vc_temp_1 bind variable is not filled
  
  ... 
    ...
  

  I found 2 solutions, but they both require an application of additional database that is, performance wise, is not acceptable.

  The first solution is to slip into an additional call to exectueQuery() before the call to function scrollToRangePage (int) or scrollToRange (int).

  The second solution is to use the method (int) setRangeStart instead of variants scrollToRange (Page). This method performs also 2 database calls.

  My question to you:

  Is there another way to satisfy the requirement of programming add a certain number of parameters of the additional where clause (using the variable binding) in combination with the pagination of the range without the need to perform queries of database 2?

  The code is tested with JDeveloper, 11.1.2.4.0, and 12.1.3.0.0 and behaves the same on both versions.

  Kind regards

  Steven.

  Have you tried to create truly VC with bind variable (rather than use binding implied var created by frame)?

  We have significant performance problems when you run the reconciliation of charge accumulation report run. We had to cancel after having run for a day. any idea on how to solve it?

  We had a similar question. As this report runs depends on the input parameters. Remember, your first round of what this report will take a lot of time and subsequent executions will be much shorter.

  But w had to apply the fixes mentioned in the MOS article to solve the performance issue.

• I'm having a problem when I open a new tab with multiple images. If there is more than five or six images they all will not be open.

  I opened emails with many images. New version is having a problem opening a tab with images more than maybe 6 or 7. Of older versions sometimes had the same problem, but the images unopened is appeared on the page as a small box empty you can try to reload. No more. Now you must reload the tab all. Sometimes it works sometimes it doesn't.

  You seem to be using a beta version. Maybe go back to a regular version and wait for V. 30 becoming a regular version, and maybe some bug.
