Hi All,

My Windows 7 x64 install comes up with a red X on the network icon in the task bar. Even though my wireless and lan are successfully connected and everything is working.

This is a real pain as I have reinstalled latest drivers and even re-formatted but nothing seems to work. Hours spent googling hasn't helped either.

My computer is a HP elitebook 8440p

If anyone knows how to help there are 500 points on the line!

thanks

Hi Kailash,

I tried the driver you suggested and it hasn't helped. thanks anyway

Hi,

Try to disable and reenable the network card under network connections.  To see whether that fixes the issue.  If that didn't then try reregistering the shell32.dll on the computer.

Are you logging in as administrator?

I had this same problem with a Lenovo Tablet, the lenovo connections manager was fighting with the built in windows wireless configuration software...
Uninstall any HP or other 3rd party wireless connectivity manangers, remove all network adapters from device manager and reboot. Good Luck

try setting a fixed speed, it sounds like the LAN adapter is having trouble negotiating with your switch/router port.

Sankar1985's tip is something i use from time to time when required, a quick disable and then re-enable usually sorts it out, but if you can edit the adapter properties and set the Speed/Duplex to something like 100MB FULL, the adapter may settle and function at that speed.  If that works, later you can try to revert it back to Auto.  Do try and have the latest driver loaded, either from the board manufacturer or direct from the chipset supplier, which you can get from the Device Manager - Win 7 drivers are continually changing just now for video/audio/chipset and LAN devices.

Hi Again, thanks everyone for the suggestions but nothing has worked complertely so far.

Saying that I have had some small success by going into device manager and disabling power management on the WLAN nic.

This has fixed the icon temporarily, but after a couple of reboots it went back again.

If nobody has any other suggestions I'll award points across all

what is the NIC chipset model??  I assume you have tried HP's driver, what about the chipset manufacturer's version - Intel, version 15.2 from 29th April 2010?

have you updated any firmware such as system BIOS??

when fixing NIC speeds, you need to do it at both the switch port and the NIC device.
