If you use Wireless on your laptop at home, XAMPP may get in conflict with your internet access !
Just discovered a new thing regarding XAMPP on Windows 7… I had this problem for 3 days and today I managed to figure it out lol…(took me a while).
The problem was that XAMPP’s Ports were conflicting with Wireless Ports, and whenever I was trying to connect to Wireless it was giving the “Connection couldn’t be established – Troubleshoot” error.
HOW TO FIX THIS?
Just go in your XAMPP Control Panel -> Config -> Service and Port settings
And switch those ports, but be careful what numbers you put, don’t place at port 80, 838123… put 85 for example… and so on…
After you do this, restart your PC. Your internet access won’t be affected by XAMPP anymore now…
