I just got a cheap no name wifi card and I installed it in my desktop. However, I get internet, but it turns off and on every second. Because it does not constantly keep turned on, I cannot install windows update, and I can't do anything. When the internet is on, I get speeds of 1 mbps and it takes about 20 seconds to load one webpage. I have a intel i7 processor and 8 gigs of ram and a Samsung 840 pro 256 gb ssd. running windows 7 and have a asus motherboard. my router is a old lynksis but my 2 other Lenovo laptops get good intrnet speeds and are constant. the wifi card is 802.11 b/g/n and the router is 802.11g.
thanks for all the help
