Problems maintaining a wireless connection (Acer Aspire)

post #1 of 9
Thread Starter 
I'm trying to diagnose a connection issue. This problem has apparently existed for a while, and I just found out recently. The computer in question is my mom's Acer Aspire 5740-5513 laptop. Quite often, she loses her wireless internet connection. When this happens, she often has to turn off her wireless and turn it back on to see our SSID show up again. First tried uninstalling and reinstalling drivers, and then did a factory reset on it (ran into problems after uninstalling drivers, but not important now). That did not help. My mom went out and bought a new router (both of them D-link dir-655), and we switched to the new one but it wasnt long before it started disconnecting again. I switched the routers out again as we can return the other one, but now the computer cannot find the wireless signal at all on that router and I'm left not knowing what to do.

It seems strange that there would be a problem with both the computer and the router, when other devices seem not to have a problem on the router. Any ideas or suggestions for what I can do now?

Sounds as if it could be the wireless nic(on laptop) is going bananas.Have you checked for wireless interference microwaves,phones etc.. Tried changing the channel of the router? I'd also check to see if windows is in control of the wireless nic or is it the manufacturer's software.Often both running at the same time can cause problems.

I wondered before if it could be related to interference. My mom reported to me first that it tended only to happen in the evening. We live in a (rather small) apartment complex, and if neighbors were coming home, I wondered if there could be more interference that way, but quickly dismissed it as I was having trouble finding anything to support this idea.

Yes, I did try this but saw no change.

Any suggestion to go about checking this? I'm really not as familiar with it as I'd like to be.

Thanks.

Here's a link on how to stop/start windows 7 zero config.This will let you know if Acer has it's own wireless software running or if win is controlling it.After doing this,just reboot the system.

What I found: First: Wired autoconfig was set to manual and not running while WLAN autoconfig was set to automatic and running. I set wired to auto and started it/restarted, though it didn't make any difference (and why would it? that's for wired). I tried disabling both, and now cannot see any networks, let alone connect, which leads me to conclude that windows is controlling it. I'm unsure again of what I might want to do now.

If it helps, the wireless adapter is "Atheros AR5B93 Wireless Network Adapter". I've searched for new drivers for it, and potentially found some from the last couple months on Atheros' site, but cannot figure out how to download them. Acer's website has the same drivers I have installed from 2009.

from last year. The most current driver is now July, 2013. Unfortunately I cannot get the download to start by clicking on the bottom blue colored link and/or the green 'Click for download' button WITHIN the Release: 2013-07-02 [July '13] box. Outside the box are advertising down loads - beware other forum members!
Any suggestions?
