... it doesnt appear to be an IP conflict since I checked and the laptops have different IP addresses when this happens. I'm also pretty sure its not a router problem since my laptop's had issues with two different routers I tried in my home.
I have a very strange problem with my laptop's wireless connection - after rebooting the (new) router, it works for about 15 minutes but then suddenly stops uploading websites even though it says the wireless connection is excellent. When I turn off the wireless for a few hours or days it starts working again but stops working after a few minutes.
What's worse - when this happens, it stops all my family's other laptops and tablets' wireless connections too. As soon as I disable the wifi on my laptop or turn it off, all the other laptops and tablets are able to access the internet again.
What the heck?
