Added a 3rd laptop takes internet down

[obdiane]

Using C6300 and I have 2 laptops logged into the Internet and when I add a 3rd laptop it takes the internet down.  Since the 3rd laptop was new I returned it but now the replacement laptop is causing the same issue.  Is there a limitation for the number of PCs that can be on the wireless?

Any suggestions what may be causing this issue?

Possible fixes:

Router configuration, browser's security, VPN's (cisco, windows vpn, etc), virus possibly (check c:\windows\system32\drivers\etc for host file ((open it with notepad to check if there's any unwanted sites)))
