Hello,
Ever since i got my Alienware mx15 back in Dec. 2010 it wont stay connected to my router. Sometimes it connects and works fine then all of a sudden it wont work. sometimes it drops the connection and sometimes it says its connected but the internet wont work/is really slow or it will have the yellow exclamation mark. I tried changing different settings and nothing has helped so far. I thought my router was bad so I took my laptop over to my friends house who also has a DGL-4500 and I have the same problem there are well. My iphone,ps3 and my other laptop all connect fine wirelessly. If anyone has any suggestions what could be wrong i would appreciate it. Thanks for the help.
