Windows 7: WIFI only connects after running troubleshooter....

WIFI only connects after running troubleshooter....

I have a Lenovo Ideapad Z585. It has a Broadcom 802.11n wireless adapter.

I have not had the computer that long but everytime I turn the computer on, my home wireless network is not connected automatically. I click on the WIFI icon in the system tray, locate my network and click connect.

I am told that windows cannot connect to this network. I run the troubleshooter which tells me to powerdown my router, turn it back on and try again. I do this and use troubleshooter to check if fixed and it connects.

So far I have updated drivers on wireless adapter and then rolled them back again. Uninstalled driver, powered down and turned machine back on reinstalling said driver.

I have done a factory reset of my router, changing login passwords. I have tried using different broadcast channels.

When the machine is connected it is excellent signal strength and I do not loose connection at all.

I have three other machines connected to router which is a Netgear DNG 1000. They all connect automatically and stay connected.

Any suggestion on how to get connection to work automatically?

To fix this problem you will need to follow all advice in the link below, I just fixed this same EXACT problem, same model Lenovo.

You must remove all preinstalled bloatware using Decrapifier as a guide, update all drivers from the Lenovo site and Windows updates, you must also remove McAfee completely using the uninstall tool.

Followed your instructions.

When I rebooted the wireless connection connected straight away. I managed to do a little surfing.

I then rebooted and connection did not start, had to go through the troubleshooting routine again.

That was pretty fast, I would make sure the drivers are updated from the Lenovo site, be sure and run the removal software on McAfee and make sure all the Windows updates are installed and use Decrapifier to remove all preinstalled bloatware.

Use the wired connection to do this if you have too.

If you are still having problems, please post the ipconfig/all from this machine.

Thank you for your advice, I had already read your link whilst looking for a solution, wasn't sure if it would work in windows 7 though. I will go through everything again and see what happens.

Next question will be, did you install any type of third party Anti virus software or firewall?

It had Mcafee installed which I have removed using the tool you can get online.

This all looks good and shows a valid IP is connected. I assume this is after you hit the diagnose button and are now connected?

This is usually a driver problem when you can't connect at start up.

Lets try the IPresetAll file to reset everything network related. Unzip and run the file until your machine reboots.

You might also want to test to see if you can connect at start up by starting your machine in safe mode with networking. This would indicate that an installed program is causing the problem.

Sorry about delays in replying, having to fiddle with the wifi everytime it reboots takes a bit of time.
