    Slow to connect to Wifi

    I have a W510 with Win7 Pro 64 and I have a Linksys WRTSL54GS router.

    Lately when the W510 comes out of sleep it takes at least 30 seconds for it to connect to the wifi router. There was a time when it connected immediately when it came out of sleep mode but that changed and I don't know what setting would do that. I have other computers that seem to connect to the router much quicker so I don't think it is a setting on the router.

    I am confused by the extra layer of the Lenovo Access Connections window and how it relates to the Windows Network and Sharing control panel.

    Can someone point me to any settings that would make the connection happen faster when the computer wakes from sleep?

    One possible culprit is "Allow the computer to turn off this device to save power" is enabled in the device manager.

    What wifi card do you have? Do you have the Thinkpad B/G/N option, or do you have one of the Intel WiFi Link cards (6200, 6300, etc.)?

    Personally, I would suggest that you uninstall Access Connections and just use the built-in Windows network settings. That frees some system resources and removes some troubleshooting complexities.

    I have three entries in the Device Manager under Network Adapters:

    - Intel(R) 82577LM Gigabit Network Connection
    - Intel(R) Centrino(R) Ultimate-N 6300 AGN
    - Microsoft Virtual WiFi Miniport Adapter

    I see the Power Management tab in each entry. Should I uncheck "Allow the computer to turn off this device to save power" in all three entries? And does this effectively use up my battery while I have it the W510 in sleep mode?

    Where do I look to determine the answer?

    You can just uncheck Ultimate-N 6300 and see if this resolves the issue.
    As far as I know, it won't consume power during sleep mode.
    (It is the other setting "Allow this device to wake the computer" which needs power during sleep mode.)
    But the consequence is that the card will be powered down less frequently when the PC is on.
    I am just suggesting this to help you troubleshooting.
