Why does my wireless internet keep turning on and off?

It all started with me noticing that my internet pages loaded slower and slower to the point where it now takes minutes to open a single page. For some reason though, Facebook is still working, even though it's logging on and off. The problem occurs when I am using my wireless network, it has been working fine for 4 months before this started happening. It looks like my wireless card is doing fine, there are not malware, virus or registry errors. I can now see that I am connected to the net all the time it just looses connection for the fraction of a second and then goes back on. It looks like the connection should be fast as well, but it's slow. I have measured it on speedometers etc. When I plug in the Ethernet there is no problem and everything works fine. The problem is most noticeable in browsers, but also affects general use of the Internet of course. I have tried so many things now, that I might have forgotten to add some of it here, if so, I am sorry. But help! What is this?? It just keeps getting worse and worse! Thank God that the Ethernet works! :) 

Best regards and a good Sunday to you all :)

While it could be your wireless radio, it is more likely interference -- there are many possible causes from nearby networks to microwave ovens to baby monitors. You may be able to remedy the problem by simply changing to a different wireless network channel.

I would take a quick look at your surrounding networks by channel and signal strength with the free inSSIDer application from HERE.

Hello! First of all thanks for your answer, unfortunately I don't think that's it. I live in the middle of nowhere and I don't think there are any new interference around here that haven't been around since June and it has been working well until the last week or so..

All other suggestions are very welcome! :)

What wireless router do you use?

If it is only about four months old it should be under warranty, so a replacement would be the easiest fix, although you would be without it for a week or so unless they will cross-ship the new unit.

Ah! It's a good suggestion, but I am pretty sure it's not the router. I can connect fine to it with my phone and my boyfriend's computer works fine with it. Sorry, for forgetting to tell you that! Just plain forgot among all the details, though I realize that was a pretty important part to forget.. I am really sorry... Any other suggestions, please? :)

I have been in connection with Samsung today and fortunately they could help me with a driver for the wi-fi card that I hadn't found myself, so it's all fixed now ;)  Thanks for all your kind help!

Despite your thought that your wireless card is fine, it seems that you have ruled out anything outside of your computer. If you are fairly confident that the card itself is working well, not knowing your hardware or OS of course, I would probably next reset the TCP/IP stack and winsock and flush the DNS after doing a quick system file integrity scan.

Open an elevated command prompt window (right click, run as admin on command prompt) then:

sfc.exe /scannow THIS SCANS SYSTEM FILES FOR INTEGRITY

netsh winsock reset catalog
netsh int ip reset resetlog.txt
ipconfig /flushdns

If none of this remedies your connection issues, the other thing that you can do is go into the network control panel, select manage wireless networks, delete your wireless network, restart and when the machine is done discovering all wireless network select yours and enter the passkey and check the connect automatically box.
