I own an Dell Inspiron 1525 and have had it about 3-4 years. Overtime, it's ability to connect to internet got worse and worse. Right now, it'll RARELY connect at all, and when it does, it's no more than 1 bar. I know its not a problem with the router, since I am currently writing this thread on my new Dell Vostro 3700, and I have 4 bars on this one, while the Inspiron has 2 bars with the yellow triangle caution symbol on top of it, and they are both right beside each other. Could it possibly be a virus thats going undetected? I've run Microsoft Security Essentials, and its not picking up on anything. How do I fix this? Any help would be greatly appreciated!
