T400 problem with slow speed internet wireless. Help, please

Hello

Just got my new T400 (276581U) and I am very happy with it. However, he has a problem. I searched extensively in this area and other forums, but have not found the solution. So any input or help would be greatly appreciated.

Problem:
upload and download speed is very slow when connected to wireless broadband. Measures download speed 1 Mbit/s on www.speedtest.net, while two other computers (XP and Vista) reach speeds 6 Mbit/s on the same network wireless download.

I tested the computer via LAN and here it downloads at normal speed of 6 Mbps.

OS: Windows 7
Network cards:
Intel 82567LF Gigabit network connection (driver version: 10.1.6.0)
Intel Wifi Link 5100 AGN (driver version: 13.0.0.107)

I have download all the latest drivers on the Lenovo support site. The pilot Gigabit Network Connection, I downloaded however Intel, as there is no driver windows 7 on Lenovo website. The Intel driver has improved my connection to the local network (before that I could not download the full site content) and it has not changed my connection Wireless for the better or worse.

Wireless configuration:
Wireless g connected to the modem access point high speed
So, to access internet, I need to connect twice, first the access point, and then click the modem to broadband. This configuration works on two other computers in the House. The lenovo is however not seem to recognize that I am online, even when I am. The symbol "not connected" is always displayed in the toolbar, and diagnostic tests tell me that I'm not online. That might relate to the problem.

Thanks for reading this. I hope that some kind soul can help.

pass under the power manager find advanced settings and then look for the Manager of the electric network... its value usually on the default energy savings

  • Problem with timer and Reset. Help please :(

    Hello everyone, I have a big problem when I put a button to reset my program. In addition, from the time of my game.

    I am doing a project named "Simonsays" which consists of a sequence of colors that you need to remember and must click on each color to pass the level.

    The problem is that I do a clock or a counter to count the time of a game. For example when I press "start" the beginning of time, and when I make a mistake in the game time must stop. There is another button named "New Game" or "Nuevo Juego" which is used to 'RESET' of the game, but I can't this is the button used to RESET.

    The game starts when you press "COMENZAR" and labview window disappears, then you will need to click on "START" and the game begins... BUT when you make a mistake, the game must be stopped with the TIME that you make throughout the game, and the game must wait until you press "NEW GAME" and newly him game begins with a new counter of the time.

    I hope you can help me. Please, I beg you.

  • Problems with uninstalling the trial. Help, please

    Some time ago I tried adobe photoshop CS4 and used the trial until it expired. About a month later I wanted to delete the files from my computer. I was rather unfamiliar with how UN-installers worked, and I didn't know they existed. Simply, I went to my finder, typical photoshop and most of the files deleted. It turns out that I deleted the re install or how ever it works. I received recently of photoshop than CS4 extended as a gift and I tried to install it. This did not succeed, the first screen that came with the installer said I always test files on my computer, and I have to uninstall them. I was told by someone who knew more about the products adobe that I had to go to the utility to uninstall. I tried this and it says critical files were absent, and I need to reinstall it from the original media. In this last month, or so I have found NO solution to this problem, and I'm afraid to delete all the other files. I could not find any help on the adobe site, and since I have not registered my product (since I have not installed so) I can't direct support from adobe. Please help all I want to do is to use photoshop and I don't like wasting the money of the people who bought it for me. Can someone give me a solution to this mess?

    Try to download and run the CS4Clean Script:

    http://www.Adobe.com/support/contact/cs4clean.html

    From CS3, you MUST use the Adobe uninstaller which is installed in the Applications / Utilities / Adobe /.

    Some users who just moved the Photoshop folder to the trash or deleted files wrong gre-willy were forced back into their car, wipe and install the operating system and all applications from the original media.  You can chance and come out with just the CS4Clean Script.  Good luck.

  • I can't get into my yahoo favorites. I spent time with AT & T and the conclusion, they have come to is that it can be a problem with Firefox and yahoo. Help please

    I use a laptop computer HP NOT mobile. Whenever I try to go into my favorites YAHOO that it asks me to sign in which I'm doing nothing does not. AT & T came to the conclusion that maybe it's that Firefox and Yahoo do not work together. I just downloaded the latest versions of Firefox and toolbar yahoo again without success. Is there something with Firefox that prevents me to enter my yahoo Favorites?

    You have the box checked for automatic private browsing mode? In this case, when you open the Options dialog box, the drop-down list usually said "conservation rules: don't remember history. In this mode, Firefox does not retain your Yahoo cookie between sessions, which would explain the problem.

    Note: If you uncheck this box and start in normal mode, you can still create private windows via the menu or with Ctrl + Shift + p.

    If the problem is not caused by a parameter of Firefox, it is possible that an add-on or software external is clear your cookies between sessions.

  • Problems with bxslider and fancybox. Help, please!

    Hi guys,.

    I'm doing a site for a client and doing a gallery using FancyBox. Everything worked fine until I implemented bxSlider in the gallery.

    The two are in conflict - although it seems that bxSlider has the upper hand it still works (albeit out of position for the moment!)! The images using FancyBox just loading the link to the picture as if FancyBox has not been installed...

    If you click here, you can hopefully see what I mean.

    Does anyone have any ideas on how I can get both to work?

    Thank you

    I do not see him the first time, you have still 3 versions of jquery. 1.7.1 and 1.7.2 jquery - latest.js (v1.8.1).

    The best way to get all these scripts work on the same page, would begin with scripts written for the same version of jquery. I know 1.8.x had some problems (of a post by Nancy O.) and older scripts stopped working. It might be better to use 1.7.2 now that I think of it.

    You may be able to use 1.7.2 in place of the first reference to jquery and empty the other two references. If this does not work, you will need to find or re - write compatible scripts.

  • Problems with video DVD files. Help, please! :)

    Hi, I recently got a DVD movie, I wanted to take off a clip. However, while I can look at the section I want to in Windows Media Player, when I import the first movie - some of them is missing! There are 4 files 4-1' 4-2' 4-3', 4-4' that make up the film. I can load everything but 4-3 missing the last 15-20 minutes, even though I know its there - cos this file is the same size as the previous one which made the entire length. Does anyone know why this would be? The DVD is not encrypted.

    Please help - its quite annoying that the small part of the movie I want is the bit that doesn't appear! Thank you very much

  • Problems with the speed of execution on my T420

    I'm not very tech savvy, so bear with me please if I have forgotten something or doing something wrong.

    Just to clarify, my laptop is a Lenovo ThinkPad T420i, Type 4178. It is about 2 years old.

    I have Windows 7 64 bit.

    My laptop takes about 2-5 minutes to turn on, sometimes it turn on at all. The screen freezes every 15 seconds, but I'm still able to move my cursor. He accused some too. For example, type 'how to download google chrome' will take me sometimes a whole minute, because the only parts of the sentence will be displayed on the screen at once. My keyboard responds very well. The problem is not with wireless internet, because even if the wireless is off the laptop computer is still incredibly slow. It is impossible to watch videos because the screen freezes so.

    I had this problem with the speed of my laptop for about 2 months now. I had finished it wiping back to factory settings, downloaded every scanner malware and virus known to man (none of them found no problems with it) and updated all my drivers.

    I don't really know how to do much on my laptop other than the use of the internet. I would really appriciate instructions step by step.

    Thank you.

    Hello. I did it all at once (up to 8 GB, SSD of RAM HARD disk and reinstall Windows), that's why I can't answer you, how did each of them, but after all, my absolutely BRILLIANT T420 representation!

  • Satellite A660 / 07P - problems with my browsers, internet connection

    Hey guys,.

    I just brought a Satellite A660 / 07P.
    I have problems with my browsers, internet connection.

    After a period of time (varies) my browsers stop to connect to internet.
    Skype works fine, as does my download manager and other internet services.

    When I run an internet system restore works again for a period of time, before picking up the handset.
    I used this happens with all browsers (IE, Firefox and Chrome).

    Any help is greatly appreciated.

    Ry ~.

    Hi dude

    Skype works fine. Right?

    This means that the laptop is connected properly to the router and the internet connection has been established successfully.
    I think that a firewall can affect the functionality of the browser. Check the firewall settings.

    In addition you should check if other installed 3rd party tools to affect the functionality of the browser.
    Verify installed tools

    last but not least you could clean the operating system. Use the CCleaner.
    Free is nice tools.

  • Windows 7. I recently had problems with loss of internet connection. When I have trouble Shooting, told me that impossible to find a driver.

    I have a desktop running Windows 7 PC.  I recently had problems with loss of internet connection.  When I have trouble Shooting, told me that impossible to find a driver.  The adapter does not appear in Device Manager.  Help!

    Hello

    Definitely looks like a problem with the network device. Check with sound
    Support, their books online, the drivers and ask in their forums (if any)
    on known problems. If there is a control of the device shipped with the system
    Manufacturer (manufacturer of motherboard for customized systems). If a device check separated
    with the support of its creator and other resources.

    You could also remove or disable the device and try a new add-on as one
    new card or device USD. None of those who are dear.

    I hope this helps.

    Try to create a new profile.

    See "create a profile":

    If the new profile works then you can transfer files from a profile in the new profile, but make sure not to copy corrupted files.

    What problems do you have that you want to reset Firefox?

    Firefox creates a new folder of old data of Firefox on the desktop?

    If reset you Firefox and a new profile is created and some of your data (bookmarks, passwords, cookies, form data) is automatically imported and your current profile will be moved on the desktop (old data of Firefox).

  • Problem with access point or wireless adapter

    Hello world

    tried to connect to my WiFi, but the convenience store detects that the problem with access point or wireless adapter.
    The drivers are up-to-date and functioning normally. There were discussions on BIOS but I don't know if I would be able to complete the task without bricking your laptop.

    Is there any online support?

    Hi smert

    Your message is not really useful.
    Why? Because no one knows all the details of the laptop, wireless network card system...
    So please would you be kind enough to provide more details.

    But despite the missing information, I recommend:
    (1) reset your router WLan
    (2) check the connection to the WiFi unsecured. (of course for testing purposes)
    (3) check the different (WPA/WPA2 AES, TKIP) encryption

  • Problems with Cisco 881, internet connection

    I have a newly addedCisco 881 connected to a firewall, which is connected to the ADSL. We have added to the wireless and when wireless clients connect to the network (using standalone APs) they are capable of anything on the 192.168.88.0 network ping. They can also ping the firewall 10.0.88.1, but only because it is on the same network as port fa4. It seems to me like there is a problem with my default routes, but they look good, and I have tried different methods to do this. Here's the running-config on my 881, please help!
