I use my computer regularly, but only recently(being within the past few months) has it started doing this. I'll be using it, but then suddenly, everything that is connected to the internet stops! I figured maybe my WiFi card was having a problem, so I turned off the WiFi and plugged in an Ethernet cord. Broken again! It goes off for a while, sometimes it will go back on, then off, and on again, over and over and over, sometimes just once every few hours. Any idea what's happening?
I'm using a Dell Inspiron 1501 with Windows Vista Home Basic and I have 1gb of RAM. Please help.

First off, if your WiFi AND your direct Ethernet connection are doing the same thing, I would be more inclined to think that the bottleneck is either your modem, or a router if you're using one (on your own connection). Have you tried resetting your modem/router? I usually shut down the computer, unplug whatever you're using to feed your connection for at least 60 seconds, plug it back in, wait for all lights to come on, and then turn the computer back on. This way, "everything" is reset at once.
If it still does it, I would look into any firmware upgrades that may be available for your modem/router.
If NONE of these do the trick, I would suggest maybe if you have another machine you could try - do it. If not, then perhaps you might want to get on the phone with your ISP.

In addition to what Rizzy has already suggested I would also consider unhooking your router and hook directly into the modem If it still does it then you no it's not your router it's either your modem (likely) or something with your computer (less likely since other computers are disconnecting too).

I have been having this problem for many days now and I finally figured out a turn around. Try it as below:
The main reason for this is the interference you have on the broadcast channel of your 802.11n freq. range.
If you dont want to go into the technicals, just follow below instructions
Right click on MyComputer> Manage > Device Manager>
Select Network Adapters and your wireless card.
Right click to get the properties tab and then go to the Advanced Tab
Here comes the important step. If you have 802.11n mode enabled, Just disable it. Your wireless adapter will rest instantly and you will connect to internet and would not drop the connection.
Hope this helps you. I gave this answer in many forums and it helped lot of people. If it does help you, Please share this information as much as possible.
