   I have a aspire 4730z with an internal wirelees card. I am using Vista And when i try to connect at home to the internet on my dynex type "n" router it will connect just fine when the AC cord is plugged in but as soon as I unplug it and run on battery power it will not connect. It sounds like a power setting and when i change my wi-fi card power settings it works fine. But the confusing thing is that i can connect just fine at a internet cafe with out the change of power settings. Does it require more power to make a "n" connection than to make a "b" or "g" connection? Or is it that ittakes more power to use a home setting for you connection instead of a public one? I have been in touch with Acer But they are VERY unhelpful. I know that there maybe no solution just wondering if you have any suggestions of info. thak you for all advice you can give.

   go to power options, then more power options, then your current plan, then change advanced settings, then wireless adapter settings, power savings mode, on battery (change to maximum performance), then apply and ok.

   this should help. it is probably just a setting on your router or interference that causes the issue at home. this should fix it, let us know if it does not.

   That is what I did and it did fix it. How would you check the setting for the router. I am kind of new to the wireless aspect of computing.

   if you have your manual for your router you would enter the ip address of the router in your browser and it should take you to the router configuration screen.

   from there, there are usually settings for better compatibility, options to disable bursting, or speedbooster, etc. all routers are different so it's kinda difficult.

   I say if the software setting fixed it, leave well enough alone. it may cost you 10 mins of battery life, but not much.

   Hmmm... I have a similar issue with my Aspire 4730Z. If it goes into sleep mode & then I wake it up, the wireless remains disabled. I sometimes try to disable then enable the wireless to see if this will force it to seek a connection, but i doesn't. And yes, this occurs even when the laptop is plugged in instead of running on battery.

   I am certain it's not my router, because we have another laptop (and a PC) sharing the router and they do not have the same prob, just me.

   As for my power settings, the CPU and everything else is set to max, even in battery mode. The only difference between the plugged in and battery mode options are the time it takes to sleep and/or hibernate the laptop.

   Is there another setting somewhere to wake the wireless up whenever the laptop's been woken up? So far, the only working solution I have is to restart the thing...

   problems resuming from sleep or hibernation are usually driver issues. try going to device manager and updating the drivers using windows updates.

   It says I have the latest drivers... But I did find a way to somewhat cut down on this issue by going to the hardware itself (instead of power options) in Device Manager and changed the power saving mode settings from "Max_PSP" to "CAM". Now the problem has occurred less, but it's not 100% foolproof because I do still get this issue at times, just not as much as before.

   When it does happen now, I can at least go to reconnect to the net and it does so within a minute or 2. Before I had changed this setting, reconnecting didn't work, neither did disable/enable wireless.

   When I emailed Support about this issue, they asked me to plug in my laptop & see if the problem occurs. Ugh, I told them the first time, then used CAPS the 2nd time, that the problem occurs EVEN WHEN PLUGGED INTO A WORKING OUTLET! I don't think they got it, cuz their last response STILL mentions putting the laptop on A/C power as part of the solution...

   It's just so very annoying to repeat myself, in CAPS no less.

   Anyways, thanks to those here who are more qualified than support, and who actually READ & LISTEN to those of us in need! :-)

   You are very welcome.

   One more recommendation is to install Vista SP2. It allegedly resolves issues with wireless devices after resuming from hibernation or sleep.

   Vista SP2 for x86 (32-bit)
   http://www.microsoft.com/downloads/details.aspx?FamilyID=a4dd31d5-f907-4406-9012-a5c3199ea2b3&displaylang=en

   Microsoft has released Service Pack 2 for Windows Vista and Windows Server 2008. The update adds support for additional hardware and standards, including 64 bit processors from VIA. It's also designed to make it easier for IT professionals to deploy the operating system, and it includes all of the security updates and hotfixes released since Vista SP1.

   The update also includes Windows Search 4.0, which is the latest version of Microsoft's desktop search client, plus improved WiFi performance after resuming from sleep mode.

   In order to install Windows Vista SP2, you'll need to have Service Pack 1 installed. Microsoft indicates that it might take an hour or more to install the update, and after you're done some hardware (like your sound card) might not work until you install updated drivers.
