Question

My daughter has an Acer Aspire 15" Laptop - model # 5738Z644G, purchased in July 2009. She has jad a problem with the wireless connection dropping out whilst she is working. The connection appears to be there and it says 'connected' but will not attch to the internet (or re-attach). When I looked at it I was able to 'disable' the connection and then 'enable' it and it worked for a while before dropping out again. I brought it to my house where it stayed 'connected' for over 48 hours. When she returned to her flat the same thing happened again. She shares the flat with a friend, who has a Mac and has no problems at all with the router. Also when I take my Dell lap-top there I have no problem Help!!

Answer

Hello,

I would recommend updating the firmware on the router (Download at router manufacturers support website) inside the house even though it connects to other devices successfully. Also, update the driver on the Acer, by going to the Acer support website and downloading the driver, then re-installing it. Restart the computer and try to connect to the network without drop out.

Let me know if that works,

Thanks,

Ryan

Hi Ryan

I tried a reply but something went astray.

I downloaded the driver - for intel wifi link 5100 agn - but no change.

I have my Dell attached and have been now for 2.5 hours with no problem.

the Acer was going off every 3-4 mins or so - with no apparent warning so if you are in middle of something it is a disaster.

 

I then looked at the adapter configuration and compared with mine.

Roaming aggressiveness was set at 5.high mine was medium

Throughput enhancement was set at enabled mine was disabled

wireless mode was set at 802.11.a mine was 802.11.a/b/g

 

I changed the settings and it seemed to be better - stayed on for up to 10-12 mins then dropped off again

 

any ideas?

Answer

Lets run a winsock fix on your Acer. Download this file to the Acer, open it and when it is finished, restart it and connect wirelessly again, then see if the problem still exists.

Thanks!

Have you upgraded the firmware on the router yet?

Do you have a spare USB wireless adapter you could plug in and see if the same problem happens with it?

no I dont have a spare router here but as I said when I had her computer at home it worked fine on my router.

I have not upgraded the router software how would I do that?

Info Request

You would need to go to the router manufacturers support website and find the specific router model, and find the firmware download (the latest one) and download it to the computer, then plug the router into the computer and log into the router configuration and then upload the firmware file into the router.

If you give me the router model and version (If it has one) I can tell you how to access the router configuration page.

Accepted Answer

I was unable to find the correct updates from the manufacturer website, they don't make it easy like everyone else it looks like.

I would like you to do a scan for malware in safe mode just to rule out every possibility.

Follow these instructions:

1.) Click here to download Malwarebytes.
2.) Install Malwarebytes scanner, update program if it asks you too.
3.) Turn off the computer
4.) Turn on the computer and press F8 multiple times.
5.) A menu will appear - select "Safe mode with Networking"
6.) Windows Safe mode will open, then open MalwareBytes and do a quick scan of your computer for bad programs and once it is done scanning, remove any threats.
7.) Once done, restart your computer and boot into regular windows.

Once that is done, test the connection. If the problem persists, lets do this:

Press Windows + R
Type in: devmgmt.msc
Press Ok

Look under "Network Adapters" and find your wireless adapter. Right click on it and choose "Uninstall/Remove". Then restart the computer and it will be installed again. Try to connect.

I am doing what you said.

I looked on the web and it looks like the latest firmware from what I could see.

I did do a Mcaffee scan yesterday but nothing came up

Great, thanks! Malwarebytes often finds things that Mcafee overlooks.

no I am afraid it still persists

I think I am going to give up and take it back to PCWorld and get them to change the adapter.

There must be some incompatibility between the adapter and the router.

Mine works

Her flat mate's works (and that is a MAC)

hers works at my house on a different router

 

aaaargh

 

thanks anyway Ryan I appreciate all your help and will now click accept
