      Solution

      Set Your Router to a Specific Channel

      1. This has to be done by accessing your internet service provider (ISP) settings page, Contact you ISP if you unsure on how to access this page

      2. If you are using a router (particularly a dual band router), you’ll want to go into the wireless settings (usually under “setup”), and specify a channel.

      3. Try using a different channel than the default, and make this settings for both of your bands (2.4Ghz and 5Ghz) if you’re using a dual bound router. Definitely do not use the “auto” setting. From our troubleshooting it appears that this is the main culprit

      4.  Try setting a higher channel, and if that doesn’t work, try different channels. It’s very possible that there are enough networks in your immediate area on the same channel that they’re conflicting with each other.

        Note: If you are unsure about the steps above please contact your ISP contact center to a walk through

      If switching the router channel didn’t work, you can try these other tips to help prevent your wireless connection from dropping.

      Check your wireless power settings

      1. First, see if your computer is managing your wireless card’s power. It may be instructed to shut off your wireless connectivity after a certain amount of idle time goes by

      2. If you have Lenovo Access Connection software installed, Launch it and click on Tools > Global Settings

      3. Make sure "Allow Wireless radios ( Wifi, Mobile Broadband and Wimax ) to be turned off when inactive" is unchecked

      4. Secondly check the settings on your wireless card via your device manager

        - Right-click on “My Computer” and select “Properties”
        - Select “Hardware” and click on “Device Manager”
        - Find your wireless card under “Network adapters” and double-click it.
        -Verify that there aren’t any auto power management settings enabled that might be shutting your card down prematurely.

      Power cycle your hardware

      1. Another thing to try is to simply shut down all your hardware – ie. your PC, your modem, your router, your laptop, etc. – anything on the network. Then power them back on in the following order: modem -> router -> PC (wired) -> laptop (wireless) and see if that fixes the issue. If not, proceed to more potential solutions below.

      Update your router firmware and wireless card drivers

      1. If all of the above hasn’t prevented your wireless connection from dropping, you’ll want to update the firmware of your wireless router, and you’ll want to update your wireless card drivers. This should solve the problem most of the time. With any firmware or driver update, please make sure you are retrieving the update directly from the manufacturer’s website.

      2. Please contact your router manufacturer hotline

      Adjust your wireless router settings

      1. Lower the MTU (Maximum Transmission Unit) from 1500 to 1492 or less (usually found on your router’s main/ basic setup page)

        Note: If your unsure how to loggin to your router settings page please contact your manufacturer hotline

      2. Adjust the following advanced wireless settings

        - Lower the beacon interval from 100 to 50
        - Lower the fragmentation threshold from 2346 to 2306
        - Lower the RTS threshold from 2347 to 2304

      Wireless connection dropping every couple of seconds

      1. Start -> Run -> and type in cmd.exe

      2. In the command prompt window, type the following: ipconfig.exe /release

      3. Followed by ipconfig.exe /renew You’ll get a status message that may help you pinpoint the issue.
