PC-MM10 internal wireless card malfunctioning

Hello all,

I have a sharp mm10 notebook, and couple months ago the wireless went psycho. It will say it is connected but then every 5 minutes lose connection and the internet will stall. I reinstalled the drivers and that did not work. Then i thought, maybe its the computer, but I have a D-Link usb wireless antenna hooked up right now (after I disabled the internal wireless) and there is no problem. So the internal realtek card is obviously messed up. What can I do to get the internal card to work?

Sharp sucks and said it could cost a lot of money for them to do any work on it cause its past warranty. Should I bring it to geek squad, or my universities tech store. Or is there a tutorial on how to install a new one.

please help,
Thanks

 

Which card is it?

 

LAN-Express IEEE 802.11 PCI adapter

 

Huh, try the latest drivers, I think Orinoco supports the card, I'm not certain on that however.

 

Did this problem start happening with Windows XP Service Pack 2?

you know, i think it might have started having problems after I installed service pack two. Hmm, not 100% sure if it was like right after. Is that what messed it up?

 

Does your access point use WPA or WEP? Also, when it disconnects, will it reconnect by iteself sometimes? Or do you manually have to tell windows to reconnect? Finally, do you use the built-in windows xp wifi utility, or a 3rd party utility supplied by a driver?

These questions are all in refrence to the internal realtek card, i assume you usb adaptor works fine.

I am pretty sure it is WEP. Secondly, it crashes, and sometimes it will come back to life after a minute or two, other times I have to repair it. Repairing works sometimes. Finally, I am using the windows XP wifi utility, I assumed everyone used it.

 

Ok, with SP2 and WEP and using the windows wifi utility, what windows does is, it disconnects from the WEP network for a second to scan for WPA networks. This is done every minute, and some wifi cards have a problem with this. You can do two things, first, some drivers come with a custom wifi utility, second, use the windows wifi utility to connect to the network then turn off the windows wifi utility to stay connected. You can shut off the windows wifi utility, thus:
1. control panel
2. Network connections
3. select the properties for the wifi connection
4. select the wireless networks tab
5. unselect, "use windows to manage my wireless settings"

So, use the windows wifi utility only to connect to the network, once your connected to the wifi network, then turn it off. You should say connected.

Please, tell me if this works.

Also, www.sharpsystems.com they list an updated wifi driver.

 

floz23, i was all excited and ready to write back that it worked. but your technique only made it better, after a couple minutes it hicuped again and then would fix itself. Got any other ideas? it might just be that the card is corrupt, but we never had any problems when we first had the computer. Thanks for your help.

 

Yes, try upgrading the firmware of your router.
