Wireless Connection lost after hibernationadapter. If the laptop hibernates for more than a few minutes the wireless connection is lost on resumption. The dialogue box that shows available networks is blank and the refresh network list does not produce a new list. Everything returns to normal if the laptop is restarted. This seems to be a common problem with various suggested solutions. Microsoft article 328647 suggests disabling and then enablng the wireless network connection. This does not solve the problem. Others suggest a .bat file with ipconfig /release_all ipconfig /renew_all This does not work either. Does any one have a solution that avoids a reboot? Thanks Hi
Make sure that the power saving in the Wireless drivers is not checked On. Check the computer BIOS to see if you can take the Network out of the StandBy list of devices.. Jack (MVP-Networking).

I have also checked the power saving in the wireless driver and unlike the wired network adaptor there is no option to turn the device on or off. Thanks for your suggestions but no success yet :) John Show quoteHide quote "Jack (MVP-Networking)." wrote: > Hi > Make sure that the power saving in the Wireless drivers is not checked On. > Check the computer BIOS to see if you can take the Network out of the > StandBy list of devices.. > Jack (MVP-Networking). > > "John" <J***@discussions.microsoft.com> wrote in message > news:38D88FDC-69A6-4CCD-A5B8-5EB2E16FCB73@microsoft.com... > >I have an ACER Aspire 5040 laptop with an Atheros AR5005G wireless network > > adapter.

In term of pure standard, there are two forms of functioning related to this issue. 1. Standby - The computer stays On, but reduces the power to certain components (like the CPU), and switches Off others (like the screen, and the Hard Drive). 2. Hibernation - This function has nothing to do with Standby. If one chooses to Hibernate, the computer is Totally Switched Off, but before going down it saves the content of the volatile RAM to the hard drive. When the computer is Switched On, it loads upon boot the file back to the RAM, and the computer is restored to the state that it was before (I.e. all programs and information that was kept in RAM comes back open). With the dire need to save battery on Laptops, many manufacturer developed concoctions of propriety software, and BIOS setting that are a combination of the above. I.e. some things are reduce in power consumption, and some info from RAM is stored in hidden files on the Hard Drive. I saw numerous amounts of time Wireless disturbances due to these concoctions. In most cases the ipconfig release/renew does the trick to revive the Wireless. However on some computers when the computer coming out of Standby/Hibernation the drivers actually think that there is No Wireless card any more. Switching Off and On resets the settings, and the Wireless starts it again. If your Wireless is factory installed, "lean" on Acer, they should made aware of the situation and offer a solution. If you are using a PCMCIA card, try a card from another Manufacturer, or a USB Wireless Card. Jack (MVP-Networking).

They do not appear
to offer a consumer support service. The only option being a general information address. I have also e-mailed Acer on there support service so they may have a solution.
