    Hello, I just recently purchased a Lenovo Ideapad U310. I'm very satisfied with everything about it... except for one little problem.

    It constantly drops the wireless connection, unless I'm in the same room as the router. If I'm in the same room, everything runs super fast, however, if I'm across the house or upstairs (the router is downstairs), it'll drop connection every 20-30 minutes. The weird thing is, other devices (4 laptops & 3 iPhones) work just fine. Even my old HP laptop has fine connection upstairs, so I'm starting to think it's a problem with my laptop's wireless card.

    Another thing that makes me think it's the laptop's problem... I was with my dad at a public library using their wifi the other day. My dad's computer ran at an average speed while mine was ridiculously slow.

    The card is Intel Centrino Wireless-N 2200. I've updated the driver directly from the Intel website, but no help. I've tried changing channels, no help. I'm not sure what else I can do. Is it just simply because the laptop has a weak wireless network card? It can't be the router's problem right? Since all other devices work?

    For the next two years I'll be living in a dorm, most likely using a ethernet cable, will this problem still appear if I'm not using the internet wirelessly?

    I'm using Windows 7 Home Premium, Intel Core i5, and since the laptop is new, I haven't downloaded/installed anything that may have brought in a virus.

    I really need a solution to this problem, otherwise I think I might have to return the laptop :( which I really don't want to do because it has everything I'm looking for in a PC. Ahhhh this is so aggravating.

    Thanks in advance, any help would be great.

    try it - plug into your router LAN connection

    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests are for what condition.

    Please post back here the make and exact model of the router and if you have a separate modem, the make and exact model of the modem.

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc

    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

    We would like to see the results from an ipconfig /all - post back the results in a reply here.

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box
    (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    Ping Tests
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.

    Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
    (A new dialogue box - black with white font, will appear on screen ):

    Type the following command
    Ping {then a space and then add the number that is shown against the item labeled "default gateway" shown in the results from the ipconfig /all}
    Post back the results in a reply here
    right click in the command prompt box
    select all
    enter
    control key + C key - to copy

    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need will need to haveNET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.aspx

    post a screen shot of the program running.
    if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

    To post a screen shot of the active window.
    1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    OR
    2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

    To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are available here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

    If you are using the Mac OS then use http://www.istumbler.net/ or
    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

    Make sure you have the latest wireless driver from Lenovo's web site.

    Moshpits, don't bother with any of the remedies suggested - nothing will work. Lenovo has admitted that there is a problem with the wifi reception of this machine. I bought mine in India and after a week of running around and writing emails to everyone at Lenovo - I managed to get a full refund.
    You are not the only one!

    Thank you, after reading this forum it's obvious that it's the machine's problem. Sigh, and I really liked this laptop.

    Do you happen to know if it's only for U310/U410 laptops? Or are all Lenovo laptops faulty?

    From the thread on the Lenovo Forum it is obvious that some 410s are faulty too. I was disappointed as well when I had to return the machine - it looked good but what use is a laptop without internet...
    Try and return it before the no-return period expires.
