E2500 has a slow, oscillating signal

I upgraded my WRT54N to an E2500 in November 2011 and I am now having problems with a slow signal that oscillates according to Speedtest.net.  Results with the router are a ping of 300-500 ms and a wide variability on download speeds in a single test of 0.5 Mbps to 3 Mbps.  When I bypass the router my results improve to a ping of about 65 ms and a constant download speed of about 4.25 Mbps which is the extent of what my ISP can offer due to my rural location.  My network has two desktops (one Mac, one PC), an occasional MacBook Air, an occasional PS3 connection (though the variable signal has rendered the PS3 useless for online play), and my iPhone when I'm home.
So far, I have reset the router and ensured the latest firmware is installed.  I also relocated the router to another section of the house, thinking it may be experiencing interference.  Interestingly enough, I can unplug the router for 10 seconds, reboot it and it works great for about 30 seconds or long enough to run Speedtest a couple of times.  Then it returns to the same slow, oscillating pattern.
I'm on the verge of trashing this thing and buying an Airport but I wanted to see if anyone here could offer some ideas that I haven't tried.

If you are getting the slow speed then try the following combinations of settings:
A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
          1] Open the software and go to the option which says "Router Settings"
          2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
         3] Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your router's main/ basic setup page). Here is the link for determining and setting up the correct MTU size: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=fbf8e8564632422eaa8ea80bf9dcba64_386.xml&pid=80&re...
         4] Then go to the Wireless tab, keep network mode as mixed,
For Channel Settings of 2.4 GHz you can make Channel Width to 20 MHz only and Channel to 6, 9, 11..
For Channel Settings of 5 GHz you can make Channel Width to 20 MHz only and Channel to 40 or 161...
B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
Then check the connectivity status…

  • E2000 SLOW AND SIGNAL VARIES

    I have a couple of Vista laptops that used to access our home network via Linksys Wireless-G Access Point and that in turn was connected to a Linksys BEFSR41 v2 EtherFast Cable/DSL 4 port Router which in itself was connected to our cable modem from TIme Warner (RoadRunner service).  
    The cable modem is new and was working fine with the WAP setup.
    To "simplify" things I recently bought a Cisco Linksys E2000 Advanced Wireless-N Router which i connected directly to our cable modem.
    Our web browsing is now slow, the signal strength comes and goes (from 2 bars to 5 bars, although RARELY 5 bars).  We are at most 80 feet from the router.  there is literally no interference beyond the drywall separating our laptops form the basement (the WAP and Router were also originally in the basement).
    I have already done all the things I have read about in this forum (re-installed, changed channels, no parental controls, updated firmware, no guest option, etc).
    Unless someone has a new idea I am thinking of throwing this thing out and getting something else but I am giving it one more chance through this forum.
    Thanks for any advice you can provide!

    Try to change some of the advanced wireless settings on the router like Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings.

It appears from these forums that a lot of people are having the same problems wit this latest update.

    Hi erastyle,
    Actually the Licensing information for the package is missing hence it is not launching any applications. You need to Reserialize the products using APTEE which you can find it on the Machine where you have created the package. If you dont have the access to that Machine then please download and install Creative Cloud Packager and it will download APTEE in the below mentioned location.
    Windows:
    C:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\CCP\utilities
    Once downloaded please follow this KB article to use the Tool.

  • Is ther a way to speed up a Mac? Mine has gotten slower and slower over time.  When memory comes close to full would that have an effect on performance? Is there a way to determine unused programs/software to remove and free space?

    Is there a way to speed up a Mac (similar to de-fragging on a PC)? Mine has gotten slower and slower over time. 
    When memory/disc comes close to full would that have an effect on performance? How should I determine what programs/software to remove and free space?

    Things You Can Do To Resolve Slow Downs
    If your computer seems to be running slower here are some things you can do:
    Start with visits to:     OS X Maintenance - MacAttorney;
                                      The X Lab: The X-FAQs;
                                      The Safe Mac » Mac Performance Guide;
                                      The Safe Mac » The myth of the dirty Mac;
                                      Mac maintenance Quick Assist.
    Boot into Safe Mode then repair your hard drive and permissions:
    Repair the Hard Drive and Permissions Pre-Lion
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    Repair the Hard Drive - Lion/Mountain Lion/Mavericks
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
    Restart your computer normally and see if this has helped any. Next do some maintenance:
    For situations Disk Utility cannot handle the best third-party utility is Disk Warrior;  DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
    Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
    Suggestions for OS X Maintenance
    OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.  Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger.  These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
    OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
    Helpful Links Regarding Malware Protection
    An excellent link to read is Tom Reed's Mac Malware Guide.
    Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
    See these Apple articles:
              Mac OS X Snow Leopard and malware detection
              OS X Lion- Protect your Mac from malware
              OS X Mountain Lion- Protect your Mac from malware
              About file quarantine in OS X
    If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
    Troubleshooting Applications
    I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
    If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack.  If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line.  Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
    Basic Backup
    For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
    1. A Time Machine preferences panel as part of System Preferences;
    2. A Time Machine application located in the Applications folder. It is
        used to manage backups and to restore backups. Time Machine
        requires a backup drive that is at least twice the capacity of the
        drive being backed up.
    Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
      1. Carbon Copy Cloner
      2. Get Backup
      3. Deja Vu
      4. SuperDuper!
      5. Synk Pro
      6. Tri-Backup
    Visit The XLab FAQs and read the FAQ on backup and restore.  Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
    Referenced software can be found at MacUpdate.
    Additional Hints
    Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
    Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
    Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
    Check for applications that may be hogging the CPU:
    Pre-Mavericks
    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Mavericks and later
    Open Activity Monitor in the Utilities folder.  Select All Processes from the View menu.  Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
    Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

  • My Mac Pro (2006) has suddenly stopped sending signal to the display monitor.

    My Mac Pro (2006) has suddenly stopped sending signal to the display monitor. It coincided with plugging in an Epson printer via usb - while the system was running. Pretty dumb maybe? Could I have damaged the video card? Anyone ideas? Thanks

    Howdy Le Batch,
    I was looking into the issue you are seeing here, and came across a helpful article for this specific situation. It's named Apple computers: Troubleshooting issues with video on internal or external displays and can be found here:
    When using an external display be sure to check the following:
    If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
    Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:

    Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
    If more than one video adapter is in use—or "daisy-chained"—troubleshoot by using only one adapter.
    Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
    If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
    Reset the system
    You can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
    Start up in Safe Mode.
    From the Apple () menu, choose System Preferences.
    Choose Displays from the View menu to open the preferences pane.
    Select any resolution and refresh rate that your display supports.
    Restart your computer.

  • My 3gs (11 months old) has been losing all signal

    my 3gs (11 months old) has been losing all signal for calls and both 3g/wifi, goes to "searching" then "no signal", and back to some signal but not for long at all. i upgraded to ios5 couple of wks ago but this was all happening before that, was hoping the upgrade would help, but noooooooooo! battery power has gone so bad in last few days too, charging up to 3 times a day!! cant afford a new phone so any help would be really appreciated.

    A reset may help. Tap and hold the Home button and the On/Off buttons for approximately 10-15 seconds, until the Apple logo reappears. When the logo appears, release both buttons.
    No content is affected by this procedure.

    Hi all,
    We have faced this problem in our production system.
    Machine is Solaris 8, sparc, Running Java 1.3.1_08 hotspot version.
    I searched around quite a bit but no good solution.
    Here is the stack trace that I have just before the JVM crashes.
    Also, I am new to gdb. I tried to connect to core dump file through gdb but i
    do not see any details. The application is running on japanese platform how can
    I read the core file?
    Regards

    You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    /Library/Application Support/VSearch
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchAgents/com.vsearch.agent.plist
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    /Library/LaunchDaemons/Jack.plist
    /Library/PrivilegedHelperTools/Jack
    /System/Library/Frameworks/VSearch.framework
    After moving all the files, restart the computer and empty the Trash.
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    This unwanted program is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination  command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

    I restarted my phone as suggested and it is still happening.
    My phone just blacks out at its own will as if the battery went dead then the apple logo appears and it restarts on it's own but my battery was still at 30% when it restarted. So that made no sense. When I try to type in my password it freezes up before I can get all of the characters in. I still hear the clicks of my tapping on the keyboard but nothing is changing on the screen. When I hit the enter button on accident it vibrated to tell me my password was incorrect but still the screen was frozen with my previous entry of the first 5 characters on the screen.
    I am becoming concerned that I may have a very expensive paperweight now.
    My husband has the same phone and his is working fine after the initial reboot.

    Thanks for the question. I understand you are experiencing issues with a third-party application after the iOS 7 update. The following article outlines the best procedure for troubleshooting this issue:

    how on earth do you contact adobe - i lost my serial number before registering my standalone software...the phone service is offshore and not very helpful - the chat (i thought it was realtime) has been slow - if i understand, you need your proof of purchase and they will issue a serial number

    To help address performance issues the Identi-e web site is currently down for maintenance.  If you are trying to redeem a product code to obtain your serial number for the Student & Teacher edition of our software you will currently be unable to do so. We would recommend installing the software in trial mode for the moment until the maintenance period is complete.
