Slow performance on the configuration established wireless

The side of my network wireless is suddenly slow (50 to 400 Kbps vs 5 + Mbps on the wired side).  All speed measurements were made using the bandwidth test AT & Ts DSL.  No obvious changes in the environment causing change although the new computers and automatic updates for XP, Vista and McAfee certainly happened.  No existing threads seem to fix the problem where my request for advice from this forum.

The environment is two access points Linksys WAP54G v2 separated by about 70 feet and several interior walls / external, connected by cables CAT5 Cisco SD2005 gigabit switch that is in turn connected to a 1070-B 2Wire DSL modem / gateway with AT & T permission.  Each access point is 'visible' to other indicators on laptops signal strength (ie. five bars close AP and a bar for the distant).  Laptops, iPhone / iTouch, a Lexmark, an Xbox 360 and a soundbridge M1001 Ruku printer wireless.  A Lenovo K series desktop computer is connected directly to the switch.  The WAP54Gs have different SSID and are on Channel 6.  The default tag and thresholds of 100 and 2346 RTS were left untouched.  Both are in AP mode.  Both refer to the 2Wire gateway to 192.168.1.254.  Both have active DHCP.  I remember tweaking a MTU setting to make the work of the Xbox, but can't find it after the update of the firmware mentioned below.  The DHCP table in the 2Wire is the IPs assigned to the various devices.  There are two 2.5 Ghz phone systems in the home.  The two have been in place, before slowing down and both are at least 20 feet removed rom the APs.

Since meeting the problem, I flashed channel firmware v3.04 on both devices (no change), tried 11 on one of them (no change or maybe slower), changed the tag at 50 interval and threshold RTS 2305 (rendered unusable, the AP), passed under Security a common to various key WPA2 WEP key.

Any suggestions are greatly appreciated.

The wired side of the LAN is subsequently degraded.  I have a PC connected directly to the bridge and got expected throughput leading me to conclude that the switch was bad.  I replaced it and all parts of her UM now LAN.  Not much of a life cycle for the switch to a year in a clean environment.

  • Very slow performance with the Web Client vSphere

    I'm testing the vSphere Web Client, but I find it excruciatingly slow - it takes almost 5 minutes just to open a session, and each click after that I take a good load of 30 seconds before the new page is completed.

  • Very slow performance of the HP 15 sleekbook

    Hello

    Two weeks ago, I bought a HP 15 sleekbook model 15-b171sd with Windows 8 pre installed. The performance has been terribly slow. When I just wanted to open Explorer, well I could grab a cup of coffee. So I booted into the BIOS and choose material control menu. All tests passed, no error not found. Then I thought that it would be installing windows 8 which may not be turned. I got the operating system that has been painful slow. I lasted for hours and hours.

    Then, same result, system performance was worse even to switch to the desktop mode and the windows menu of tiles and back 8.

    Do you have any tips for me what to do?

    Here is a link to the contact for HP options.

    The unit is still under warranty, so I would say that as a first point of contact to facilitate the replacement.

  • Question about the configuration of wireless networks

    I managed to set up my laptop and desktop computer to access the interest through a Belkin WLan modem router. So why can't they access each other or the printer that is attached to the office. Computers independently access the router via a wireless connection.

    The printer is connected to the desktop via the parrell port. Each are running xp home.

    Hello

    In so that they can access the printer, you must have the shared printer. Go to start-> settings-> fax and printers, then go to your printer, right click and go to share. Then share it. Now go to your cell phone and go back to the printers and Faxes page. Now click on add a printer and click on that it is connected to the network via another computer and add it to your laptop. Now it should be usable on the network. So that your computers to see each other, they will have to be interconnected, in a literal sense. Access networks and create a LAN or WLAN, first of all, the office, then the laptop. After that the two of them, they should be interconnected and see themselves. A routher is dandy, but for some reason, some computers do not always act as well as on a network up to that force you to.

    Hello

    Many new machines with Windows preinstalled have much extra "Bloatware" which can really slow things down... If it's a laptop especially...

    It's a fairly common thing for 3rd party security to take a big hit on your internet connection...

    I'm just using the Windows Security, and my internet works in max, most of the time...

    Over the weekend and during the first Monday Night Football of the season it was really slow.

    You can take a look at the Stratup taskmanager tab and do a little research on Google about the things you find.

    You might be able to disable a lot of it...

    Same thing in msconfig... Services tab... Click on the box hide all Microsoft downstairs and check what is excluded.

  • dealing with slow performance of the game?

    So, I run a difficult obstacle, trying to develop a game for iphone 4/ipad.  The best comparison to what I am would probably be Plants vs. Zombies. My road bock is that I can't have more than 10 enemies on screen bofore that get significant slow down. Update 2.7 helped a little, but not enough to really get the preformance I need.

    My the game resolution is 960 x 640.  All on-screen objects are rasterized (png) and founded. I went to GPU mode.  The purpose of 'the enemy' average is about 60 x 100 pixels and a dozen images to animation.  I do not use blending modes and no change in property .alpha. No interpolation.  I basically pulled out all major aonther at some point and just tested code with a large number (say 14) enemy objects (animation film clips) on the screen (and seen slowly dragging him down). I am also a pool of objects almost everything.

    I saw games push WAYYY more in terms of how much they spend on screen, so I wonder if it's one of the limitations of the Flash engine?  I can only imagine that I am just short of memory?

    Any ideas or insight on the people who run into similar problems (and hopefully some solutions) would be greatly appreciated.

    Thank you

    What you were trying with visibility almost is a good idea! If you use keyframes to the CS5.5 visibility, you can set up a market cycle that served its purpose by showing only one thing at a time.

    Unfortunately, when the timeline loop caching is lost. So, try your idea, that duplicate the effect to last long in the timeline. He had to work and would save you have to use the code to get the same results.

  • Extremely slow performance since the reinstallation of Vista Acer restore disk

    I have serious problems with my laptop since the reinstall Vista for my Acer recovery media.  The CPU usage goes to 100% whenever a program is open or a transparent effect comes into play.  An example would be allowing the Windows Sidebar and hovering the mouse over the bar to make the window fades.  He sees the jump to 100% CPU has not completed the fade in and out.  SD video play is more correctly, hence loss of images and speaker crackling and content HD is completely out of the question.  Web-based video streaming is possible and even simple tasks like opening the windows and web browsing is stupidly long wait time while the system catches up.  Even the pointer of the mouse leaves trails!

    I'll list the steps I tried to try to get to the bottom of this below.

    -Uninstall most software Acer
    -Reinstalled the graphics and the sound card drivers
    -Installed all the Windows updates available
    -Disabled Windows Update service
    -AV/Firewall software uninstalled
    -Checked starter and Services to search for suspicious programs
    -Scanned for viruses/Spyware
    -CPU Ran diagnostic tool (forget the name) - ran for an hour, no warnings or errors

    TaskManager is used, the processes using the CPU is what either the application is currently in use at this time (for example, when sidebar is faded, jumping to use upward in the process manager, then comes back down to 0 until another task is carried out), there is no single process using the majority of the processing power and no CPU usage is reported when the system is inactive.

    Any suggestions on what to try next?

    Hello

    You have installed something other than AVG?
    It was like that immediately after execution of the recovery?
    Why do you run recovery in the first place?

    You had a bad load of recovery, rerun it wouldn't hurt.

    You can also have a problem of material, in which case you will need to identify and replace the defective part.

    It is also possible that you have a rootkit, and moving requires more than a simple reformatting/reinstall. The answers to the above questions would indicate more precisely what direction you should take.

  • High CPU use/Slow Performance after you install the updates of Windows

    I run Vista Business 32-bit.

    After you install many Windows updates in the last few days, I've known very slow performance after the system worked for a while. Resource monitor shows 70-100% CPU usage, even when you run all the apps (that I know of). This makes everyhting grind to a halt, same trip that the mouse jerky movements. I ran several complete system with McAfee anti virus scans and not found problems (using the latest software). The detail showed the so-called ", PID4 NT kernel and system" using 18% avialable CPU capacity, but this process is not always shown to use much more capacity when the slow performance occurs. Nothing else don't use much capacity CPU, I see.

    More recently, the capacity of the CPU became crazy, jumping from zero to 100% usage in a back a suite oscillation. When I shut down and restart, performance improves, but erodes little by little over time.

    Is this a sign of a virus, or is it a problem with the recent Windows updates or some kind of conflict with my software such as McAfee? How do I tell me what to do? Anyone else have this problem with the recent Windows updates?

    Help!  Thank you!!

    McAfee applications (and Norton) are known for not not upgrade (or uninstalling) itself.

    1. download the McAfee Consumer Product Removal, save it to your desktop tool: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe

    Note: Be sure to back up data that you want to keep before you start the defrag or wipe the hard drive.

    Important: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attack.

    I hope this helps. Otherwise, feel free to write us again and we will be happy to help you.

  • First Pro CC 2015 | Extremely slow performance

    Does anyone else know extremely slow performance after the update?  I tried all the usual items, delete the cache, reinstall etc... Last try was install on a clean system... still very slow performance.

    Intermittent symptoms are: push the space bar to play - 1 or 2 second hesitation, pushing the space bar to play audio but video playback does not work, some filters is blurry, curved RGB for example take 2 ~ 4 seconds of 'kick '...

    Same exact same system configuration on the previous version had no issues and was very sensitive. Also this on 2 other systems that have been updated. All Mac.  Customers are starting to notice the hesitation on the reading that is really powerful.

    Turn off your automatic backup in the preferences. I was about to tear my remaining hair, dealing with the same issues as you. This fixed it for me. It will be useful. BTW, it wasn't my idea. It seems to help a lot of people and systems here lying around.
