So here is the situation. I have a Toshiba Satelite L510, running Windows Vista. The wifi died completely and I suspected a virus., I did a factory restore. However since starting over with it, updating drivers and installing everything. I still have a WiFi problem, although now I get a connection.

The wireless network connects on the laptop... it gets internet and all is fine. However then randomly every few minutes or so the internet drops... yet it maintains internet connectivity. The internet then proceeds to work again. Which means killing downloads.

How do I work out what the cause is? If its the laptop? Or the router? Or a setting?

Would appreciate the advice/help!!

EDIT- More info!

There are other computers and laptops on the network connected, however they are all Windows 7 and have no issues. Its just this one Toshiba laptop that seems to loose and gain its internet connection... yet as I said it appears to not loose the network. (Although when it does this and I check the network and sharing centre is says "Identifying") instead of the network name.

I also noticed that if I do an internet speed test while the internet is connected, it downloads fine then looses internet during the upload stage (Every time)

Check that your laptop IP address is not the same as another network device.

Check your router isn't set to 20 & 40 hz frequencies. Just drop down to 20 only. It sometimes fixes issues like this.
Hope this helps.

Hey there, there is no frequency option on my router. Just a channel option.

Hey everyone. I have worked out that the issue is somehow related to uploads. Even uploading a 28k file while the internet is on, disconnects the internet or brings up an error. Downlaod, watching videos etc is fine.

This only happens on wireless, its fine on the cable... Once I did all the windows updates it stopped disconnecting every few minutes and is now just only on certain sites when I click "Submit" buttons for searches (such as trademe) or upload a photo to email.

I am really baffled by it.

Madeline,

Turn off the laptop's wifi, borrow an external wifi dongle and try that ... it may help isolate the problem as faulty wifi chip, or driver.

If the above test works fine, go to Toshiba web site and find latest wifi driver for that model and try again.

I had similar experience with an internal wifi unit slowly dying.

My Dell did that. Replaced the minipcie card with a nice new Intel 802.11ac one and it's all smooth as now.

Thank you all for the confirmation, that was what I was thinking.
