I intend on replacing my 1397 WLAN minicard because I’ve just about had it. It won’t stay connected to my internet like it used to. I noticed that I keep getting knocked off my internet ever since we secured our network.  I also noticed that it only stays connected on unsecured networks. Is there any way to fix this? I never stay connected long enough to do anything on the internet! It’s annoying to keep reconnecting or to constantly refresh my windows. No other laptops or computers in my home have this problem...

 

Either way I do plan on changing my wireless card to the 1520 WLAN minicard.. but are there any other wireless cards out there besides from dell? Anything from Intel?

 

Here are specs of my laptop

Dell inspiron 1440

Windows 7

Pentium® dual core cpu 2.20 GHz

RAM – 4 GB

System type – 64 bit

Dell wireless 1397 minicard

My netgear router – 802.11g radio
