Wireless problems

Having trouble solving this issue. Laptop gets kicked off wifi on regular basis. Only way to reconnect is reboot. Laptop was replaced with identical laptop from sony. Updated to latest wifi drivers. Power settings for everything are set to always be on. Changed channel for wireless. Replaced access points with another brand. Put in a new USB wireless from a different manufacturer. Updated BIOS. No other computers at this house are having issues. I cannot find any setting anywhere that is causing this. Everything seems to point to the laptop but I cannot for the life of me find what on the laptop is causing this.

I was about to suggest trying older drivers by a release or two, but then I saw you tried USB wireless.  Did you disable the onboard wireless when you did that?  ...RG

RGRodgers - Yes Disabled the onboard wireless when I added the USB wireless.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Are there any event logs or device logs that point to this issue?  ...RG

When you say you checked "all power settings" , did you set Windows Wirelss and any third party wireless managers to set the wireless to Maximum Performance (not Maximum Saving).

Also, what operating system is the Sony? and the other laptops?  I had to change my wireless router after I upgraded from XP to Vista (and now Wiindows 7). Can you test this laptop on a different wireless router? And how does it behave on a different router?

RGRodgers - Nothing in the log that I can see

thinkpads_user - Running Windows 7. Other computers at his house are all Apple. You are correct. Set power to max performance. In the properties for the Wifi Adapter unchecked let windows turn off this device to save power. Computer is set to never sleep, hibernate, or turn off hard drive.

There may be a router incompatability (I have seen that before). Try your Sony on a different router to check.

Thinkpads_User  - The way it's setup right now is there is a Verizon FIOS router but the wireless is turned off on it. There is a wireless acces point setup closer in the house to where he uses the laptop. I have tried replacing the access point with one from a different manufacturer.

Are there other computers that are maintaining a stable connection?  If not, you might want to run a wireless survey to see if other local routers are interfering?

Did this problem start with the replacement of the laptop?

If you mentioned this, I am unclear.  What are the make and model of the WAP and the card?

Also, how often do the drops occur?  Do they have a specific period or are they random?

Here is an interesting article going into many ways to resolve wireless drops.

Also, I would phyiscally take the laptop to an entirely different environment outside you office. If it fails like always, you may need to re-install the operating system to clear it up.

You said this laptop was a replacement.  Is it a new install?  If so, I am not sure a reinstall would give you anything but what you have...RG

We had a new (about 6-8 months ago) sony laptop and it was happening on there. Sony replaced the laptop (for other reasons) and we were hoping that would solve the issue but no change. I can't imagine a repair of the OS would do anything as this has happened on 2 brand new laptops. No other user has any wireless issues. Today I tried turning off all sony software that starts at boot and will let you know if that helps.

One interesting this is that when the connection drops you cannot just click on the wireless icon in the system tray and try and reconnect. Nothing happening when you click on the wireless icon !!! Only solution is to reboot.

Based on other users not having any issues, using 2 different wireless access points and 2 different wireless adapters that it is something running on this laptop that is causing this. Like I said, I will update if turning off all sony software makes any difference.

I got this figured out. In the properties for the network card I unchecked anything that was not neeeded (IPv6 and other ones that the anti virus/firewall software put there). Once I unchecked them it started working fine without dropping out.

John HurstBusiness Consultant (Owner)Commented:
In my opinion, this is a very poor solution because it is misleading and, in general, incorrect.

While it may have worked on this machine:
(a) AntiVirus generally does not install network protocols, and,
(b) IPv6 was meant to be there in Windows 7 and it works on every Windows 7 machine I have worked on (several dozen).  

Moderators: I will, of course, defer to your judgment, but I think this question should be deleted instead. ... Thinkpads_User

I wrote Antivirus/Firewall since it's an all in one program. The firewall program we use def had an entry in the network card properties. I agree that disabling IPv6 had nothing to do with the solution I was just including that as an example of the one of the things I unchecked.
