Hi All,
I need your assistance with my laptop. Every time I restart my laptop it takes about 5 to 7 minutes to connect to my wireless network, not only it takes a long time to connect, while is connecting if I double click on any program such firefox, word or excel it also takes a long time to open these, the whole system slows to a crawl while is connecting to the wireless network.

Once the laptop connects to the wireless network then everything is okay, no issues like nothing happened.

I have reinstalled windows, updated drivers including Intel Centrino, windows is up to date. All other devices connect to my wireless network quick and easy without any issues.

Any ideas how can I fix this? Is really frustrating.

Delete the Wireless Profile and make a new fresh profile.

From an admin command prompt.

netsh wlan delete profile name="name of profile"

Then use the Wi-Fi icon to make a new profile.

If you're not using any of the Microsoft Networking features (i.e., you only use the network for internet access, not things like sharing files or printing to another computer on the network), try disabling:

  • Client for Microsoft Networks
  • QOS Packet Scheduler
  • File and Printer Sharing for Microsoft Networks
  • Link Layer Topology Discovery Mapper I/O Driver
  • Link Layer Topology Responder

in the WiFi connection profile and see if that improves the situation.

See this page for a more detailed commentary.

Disabling the suggested things will not speed up Wi-Fi (not on any machine I know) but will have a detrimental effect on operations. In my opinion, do not disable these things.

Here we must agree to disagree.  It is within the pale that one of them may bear on the problem; if so, it is worth checking that possibility.

As I noted, even disabled, Wi-Fi won't speed up. Been there and done that.

Then I get clients "Someone messed with my computer at the hotel and now I cannot connect to anything"

I am just stating my own viewpoint of the trouble that follows disabling long standing Microsoft Protocols .

Try two things:

1. Uninstall the wireless card (Device Manager) , shut down, start up and install it again.

2. Run System File Checker. Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete and restart again

Have you tried a different network. We assumed it was an issue with your computer because you say all other devices connect properly.

But at this point, see if your computer connects properly with a different network.

So your computer is in trouble. With all you have done, you now should consider a Windows 7 Repair Install. You should back up first and you need the Windows 7 DVD. Here is a Seven Forums tutorial to assist.

http://www.sevenforums.com/tutorials/3413-repair-install.html

As a point of reference, I have all the protocols enabled on my Wi-Fi card and aggressive roaming is set at medium. My Wi-Fi connects quickly before I log on to my computer (Windows 10 Pro and Intel card (N6205) similar to yours.

Disable IPv6 on the wireless card (just un-checkmark it in TCP/IP properties of the wireless card).
Sometimes IPv6 loves to be the master of everything.

In a properly running machine, IPv6 does not cause any issues. So long as IPv4 is also installed, you can safely leave IPv6 installed also.

I politely disagree....Windows implements RFC 3484 and uses a prefix table to determine which address to use when multiple addresses are available for a name.

By default, it favors IPv6  addresses over IPv4 addresses therefore IPv6 takes precedence over IPv4.

https://tools.ietf.org/html/rfc3484

Therefore if you don't want IPv6 broadcasting on your network and you are not using IPv6 then it should be disabled.

Hi All,

I tried repairing Windows 7, disabled IPv6 on the wireless card and change aggressive roaming to medium but no change, the issue remains.

Not really sure whats going on with the laptop, I guess a clean install may be necessary.

Thanks.

Since a Repair Install did not fix the issue, then, yes, now you must back up the system (documents and data), format and reinstall Windows. That will be the best for long term stability.

Be sure to install Windows 7 SP1 or download SP1 and install it first

Have you tried resetting Winsock and the TCP/IP stack? If so, you're down to one of two possibilities:
1) Windows is screwed up and needs a reinstall as John has pointed out.
2) Your wireless card might have issues.

If possible, I'd recommend seeing if you can borrow a USB wireless card and see if the same issue occurs.
