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).


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.

  • Pavillion G6 2014tx: wireless connectivity problems

    Since the last 2-3 months, my wireless connection does not work correctly. This happened right after that I did the partitioning in the D drive (I don't think this is the main cause). What is happening is that, all of a sudden when internet does not bar shows signs of yellow warning and 'tells' LIMITED ACCESS wireless network. When I try to solve problems, it will give no problem. Then in Device Manager, I tried to uninstall and install again, the internet worked for a while, and still the same problem occurs. When I tried to call to the service center, they told me that I have to buy CDs to retrieve a value of rs500 because I did not these recovery disks. I'm in serious trouble please help...

  • Windows 7 wireless connection problem

    I just bought a brand new Alienware m17x and all drivers are up to date... .IM with broadcom wireless network adapter. The strange thing is that last night I was on the internet for several hours without any problem using the wireless, but this morning iwas unable to use my wireless internet access. This has happened several times now. Sometimes it says "not connected - no available connections" and sometimes he says "not connected connections are available" when she says, links, I try to connect to the network, but it says "unable to connect to the network. The only time wherever I was able to connect to wireless internet, was when my computer is automatically connected to my wireless network without me having to select the network and attempt to connect. I read things about windows 7, with a mode of "sleeper" for wireless connections or something, and that can be the cause of it and that it is better to turn off or downgrade to xp. I am really frustrated because I am not able to connect wirelessly and I hope you guys can help me find a solution.


    Guide to correctly troubleshoot wireless M17x
    with Dell Wireless 1510/Broadcom card
    by Glzmo

    Since many new Alienware M17x all powerful users, especially those who use Windows 7 as operating system there are various problems with their Wi - Fi connection and post threads asking how their difficulty over and over again, I decided to write this guide to show them how to solve these issues properly Commons. The solutions in this guide were created and designed for 64-bit Windows 7, but they may also work in Windows Vista, although these problems were experienced by users of Windows 7 mainly in the past. It could very well be that the problems start occurring in Vista as well with the new drivers and Windows updates.

    I. may not connect to the wireless network and or see the wireless adapter when the Ethernet cable is disconnected
    If you sometimes or always unable to connect to the wireless network, cannot connect to the wireless network when the Ethernet cable is disconnected, unable to connect to a wireless network unless you restart once to get this work and other weird problems to be unable to connect to a wireless network continue with section II. Otherwise, continue with section II..

    Sleep of a.i. Disable on disconnect device
    Some new Nvidia Ethernet drivers have a function called sleep device to disconnect. This is the culprit. Normally, it should only put the card Ethernet to sleep when the cable is disconnected, but it is buggy and thus kill the wireless connection as well.
    Follow these steps to disable this feature on your Ethernet Nvidia card:

    1. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
    2 double-click network adapters.
    3 double click on NVIDIA nForce Networking Controller (Yes, that's indeed wired Ethernet adapter).
    4 click on the Advanced tab.
    5 select sleep on disconnect device.
    6 set the value to disabled.
    7 click OK and wireless should work again (may require a reboot later, but probably not).

    I.b. install different drivers (older) who do not have the device sleeping on disconnect feature.
    The above does not work or if you are not comfortable with these drivers, follow these steps (if step A.i. was successful, you will not need to follow these steps). Take care to create a system restore point before proceeding:
    1. click the Windows Start button in the taskbar.
    2 click on Control Panel.
    3 click on uninstall a program.
    4 in the list, double-click Nvidia drivers.
    5. Mark Remove only the following.
    6 in the box below, only check the Nvidia Network driver.
    7 click Remove and follow the uninstall instructions.
    8 restart the system, if you are prompted to.
    9 download another (older) driver from Nvidia.
    10 install the old driver.
    11 when asked what drivers you want to install, select only the network driver.
    12 follow the installation instructions and restart your system if prompted.

    II. Low or fluctuating wireless connection speeds
    If you have problems with WiFi low connection speeds (such as rates decline over time, the speeds are much lower than they should be, network lag/stutter in online games, loss of light packets, loss of internet connection as LAN works and other weird things) or speeds of fluctuating wildly without apparent reason wireless connection install the version of the Dell Wireless drivers instead of the standard Broadcom drivers. All older drivers will usually cause the speed of connection under normal. Note, however, that you may need to install the driver manually via Device Manager as the pilot was not released for another laptop and is not officially available to the M17x yet - that's why the installer won't work. Take care to create a system restore point before proceeding.
    Here is a step by step how manually install the driver:

    1. download the drivers Dell Wireless
    2 check out the R29128.exe file using an extraction utility like WinRAR or just run it and quit the installation program.
    3. open the Device Manager of Windows by pressing Win + break, and then click on Device Manager on the left side.
    4 double-click network adapters.
    5 double-click the Broadcom 802.11n network adapter entry.
    6 click on the driver tab.
    7 click the button Update driver .
    8 click Browse my computer for driver software.
    9 click on Let me take form a list of drivers for devices on my computer.
    10 click the disk provided .
    11 click Browse.
    12. select the folder that you extracted the drivers you just downloaded in step 1. in.
    13 select the subfolder DRIVER_US (if you are in the United States), DRIVER_JP (if you are in the Japan) or DRIVER_ROW (if you are in the rest of the world), according to the region you are in.
    14 click on the Open button.
    15 click OK.
    16 select the driver that says Dell Wireless 1510 Wireless-N WLAN Mini-Card of the list (you may have to scroll down to see - it presents itself as second to the last in the list for me).
    17 click on the Next button.
    18 you will get a warning that the driver that you are about to install is not compatible with your hardware. Ignore the warning and proceed with the driver installation.
    19 restart your system if prompted to do so.
    20 your new driver should now be properly installed and the speed of your wireless connection in the order.

    III. If all else fails (or you've just had enough of boredom arising from the Dell Wireless 1510/Broadcom card)
    Replace the Dell Wireless 1510 problem with a card half-mini Intel Ultimate N WiFi Link 5300 A/G/N (use the bluetooth as the third antenna antenna or buy you an additional antenna for this). It works very well with the M17x, has better connection speeds to strips of the 2.4 GHz and 5 GHz (this last has speeds really bad on the Broadcom/1510), it has not required to jump through the hoops to make it work properly and much more, it works with standard drivers and Intel maintains their drivers up to date. It is also much more reliable and faster as well, especially on the 5 GHz band, but also on the 2.4 GHz band.

    For more information on the subject of tweaking the settings of your Dell Wireless card, check out the official setting advanced properties: Dell Wireless WLAN Card User Guide.

    I hope that this guide will help you solve your Wi - Fi connection and allow you to enjoy speeds of complete wireless connection on your laptop Alienware M17x.

    Addendum: Quick links in this Guide

    Driver wireless Dell version
    Download the driver for the Mini PCI Dell Wireless 1510 card used in this guide.

    Broadcom 943xx Wireless Driver version
    Download the latest Broadcom driver as an alternative to the Dell a little older driver who may or may not solve the problems more. Some have seen more success than with the drivers with it (you need to use the 802.11n network adapter driver rather than at the entrance to Dell Wireless 1510 Wireless-N WLAN Mini Card in step II.15. the guide when you use this driver).

    Setting advanced properties: Dell Wireless WLAN card User Guide
    Reference Dell official Manual/Guide on the various properties Advanced Dell Wireless cards.

    Card Intel Ultimate N WiFi Link 5300 A/G/N Half-Mini
    Link to buy the demi-mini card Intel Ultimate N WiFi Link 5300 A/G/N of dell.com upgrade the crappy Wireless Dell 1510/Broadcom card that comes with the M17x.

  • 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/%");
    vo.applyViewCriteria(vc, true);
    // enable range paging
    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,, and and behaves the same on both versions.

    Kind regards


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

  • Performance problems since the update of 2015.6

    Hello together,

    Since I updated lightroom yesterday to version 2015.6 the performance on my machine is incredible bad.

    My system:

    -MacBook Pro (retina, mid-2012)

    -2.3 GHz Intel Core i7

    -16 GB 1600 MHz DDR3

    -NVIDIA GeForce GT 650M 1024Mo

    -OS X El Capitan (10.11.5)

    Lightroom synchronizes actually 1400 photos, but even if I stop this process, LR uses CPU so I can't work in other programs like Photoshop (updated yesterday, too). I detected this performance problem as PS freezes when I used the Healing Brush tool.


    I don't know what's happening LR, but is not ideal for my workflow.

    Does anyone have an idea?

    If I close LR I can work in PS, even though the Healing Brush tool is slower than in the version before. But I can't always close and open LR.

    Thank you

  • HP Pavilion 15-n005sg: performance problems and worsens


    I bought this PC here is a year, has been a very good PC with good performance, but has been doing more and more slow to the month, for example, I used to run Diablo 3 on average - high specification with 60 fps constant with no performance problems, but that in the end, I can't still running at ultra low care without screen freezes and fps drops to 1-2 as well as the League of legends and other games.

    It takes more and more time for my pc to turn on, which was like 30 ~ 40 seconds not takes like 3 minutes.

    the performance gets really bad and should not happen on a pc of 1 year.

    What can I do?

    An update of the system may be your best course of action.

    Your data, files, etc. will be retained. Any Windows apps store is kept.

    Any program that came pre-installed is preserved.

    BUT all programs which are not in the above categories will have to be resettled; your games, printer, etc.

    > There was another option to check why prod database behaves differently?

    Yes.  The trace file, TRACE the request and review (or the tkprof).

    How to investigate DB performance problems?

    You can refer to the oracle support doc: Doc ID 1362329.1

    In case you have difficulties to access the Oracle support, I copied some of these inline content:


  • [ORACLE] performance problem with high enq: TX - line lock contention waiting


    I have a performance problem involving high line response to locking conflicts that I can't wait.

    The application updates the specific table about 1200 times for my AWR report representing 2 hours.

    This update represents 98% of the db_time and wait to enq: TX - line lock conflict is:

    -83 796 waiting

    -245 441 seconds

    The application updates a row both an unprecedented SELECT UPDATES. This is the query:

    Update my_table set creationtime =: 1, modificationdate =: version 2, =: creationuserid 3, =: fortesting 4, =: 5, modificationuserid =: participation_uuid 6, =: actimenucontact 7, =: allegroid 8, =: campaign_uuid 9, =: desjardinsemployeetype 10, =: effectiveparticipationtype 11, =: family_uuid 12, =: fetchpasseport 13, =: 14, healthratingfilldate =: hoursofsleeptimecommitment 15, =: igaid 16, =: initialsubscriptiontype 17, =: minutesofsleeptimecommitment 18, =: goal 19, =: partner_uuid 20, =: 21, promotionalemails =: 22, readrules =: sccsubscriptionprovenance 23, =: = subscriptionprovenance 24,: 25, supportemails =: where the 26 uuid = : 27 and = version: 28

    Clause where is filtering on uuid which is the primary key of my_table.

    The uuid is a specific user and two users would not update the same row, what could be the reason for this wait event?

    Thank you

    Why guess when you know.

    Watch ASH data for these events to the queue.

    He'll tell you sql id as well.
