Your wireless driver seems to be causing some problems and is rather outdated, check the Dell website for any updates.

• bcmwl664.sys - DRT

i checked the driver and tried to update it but it says it's updated already even before but the problem persist.

Update your System Specifications with Speccy, and then copy this information into your System Specifications: Go to your UserCP, and then select Edit System Spec in the left pane. Copy the information from Speccy into the required fields. These System Specifications will then follow your every post.

Please also upload a .NFO file:

Start > Type: msinfo32 > File, Save

good day mr blue robot, thanks for acknowledging my message, i did the system specs already, but whenever im trying to upload the nfo file it say its not a valid file,
so i uploaded it somewhere else... sorry if im not ff directions T_T but NFO is not in the list of the attachable files.

NFO File. NFO - Free Download - Uploading.com

Create a zipped folder and then place the .NFO file into the folder. Upload the folder in your next post.

If you have Acer laptop, then why are using a Dell Wireless Driver?

Here is the Support page for your system:

• Acer Aspire 4755 Support

Although, bcmwl664.sys is for a Dell Wireless card.

here's the zipped NFO

i dont know, its the one installed here in this laptop when i got this..

from the support page, which one do i download?

i installed the
Wireless LAN Broadcom Wireless LAN Driver 5.100.235.19 31.7 MB 2011/07/05

i'll see if it'll work :)
will post here again if the problem remains :)

Reduce the number of programs at startup, to avoid any driver or program conflicts:

• Troubleshoot Application Conflicts by Performing a Clean Startup
• Startup Programs - Change

This that the exact model of your laptop?

The driver which you should install is highlighted in the above image.

EDIT: That's right :)
