Vaio wireless problems

Lets start off with, the fact that i have terrible luck with technology. My latest fail is when i accidentally BROKE an atm at my local bank. However, that is not my problem.

Just last year i bought a Sony Vaio FW series notebook, but almost immediately i started experiencing problems. For some unknown reason at random times, my internet/wireless functions will suddenly shut off. This will force me to restart my laptop to regain my internet. Sometimes it gets so bad that it freezes while it shuts down for the restart. Anybody else experiencing the same problems i am having? I have already replaced this laptop before with the same results. I am beginning to think this is a problem on Sony's part and not because of the software.

Does anyone experience the same thing i am experiencing? Solutions?

Well my laptop is almost always plugged in, usually the wireless stops working while i am surfing the net. Oddly, the problems does not happen if i were to just stop surfing while i wait for a video to download (ie megaupload and such), or while i play an online game (such as megaten or Grando Espada). I am using a Vista Home Edition 32bit. The problem seems to crop up more on websites that have to load a lot of graphics such as ign.com. The problem lessened when i dled a firefox addon to disable the ads on the site.

Hope this helps.

If I were you, I'd download updated drivers for your wireless first (check what you got in the device manager under network adapters), then uninstall your adapter, then I'd run a registry sweeping software like ccleaner then restart and install the updated drivers. If that doesn't work then you could likely have some sort of malware on your computer that you need to get rid of. Start off by disabling anything suspicious in your startup processes. Ex. your start folder in your programs menu and the startup tab when you open your system configuration utility (start->run-> type msconfig in box). If your unsure what some of those items are, just google them. If none of the above works and your pretty confident you don't have any type of spyware on your laptop then it might just be your router acting up. Hell maybe people are stealing your wireless? set your router to an unused channel, give it a specific name and make sure your using WPA encryption.

I'm pretty sure i have a secure router, since it is password protected and only a couple months old. But, thanks for the advice, i'll try them out when i have time/

Thanks again!
