Hey guys,
For the past 2 weeks my Dell Inspiron 15z 5523 wireless card is not working properly. I don't know why but it looks like the wifi strength dropped significantly, it only detects Wifi networks in a 5 meter range (16 foot) or less.
I already tried:
1. Uninstalling drivers and installing the most current driver
2. Uninstalling drivers and installing like 10 differents versions of drivers.
2. Changing wireless power mode to maximum performance.
3. Changingtransmit power to highest.
4. Unchecking allow computer to turn off this device to save power.
5. Opening laptop, cleaning wireless card, make sure the wireless card is properly installed.
I know is not the router because every other device in the house or in my workplace works right away.
What else can I do?
