I have a new laptop with 64 bit Windows 8.1. Although it has its own WiFi adapter, there are some parts of my house where the signal is not strong enough; so I use another adapter that has an amplifier. It's an EnGenius with its own driver and software. I have reasons to use the laptop at this specific location.
So now I get a strong signal. However strong the signal is, I keep getting a limited connection with no internet access. I tried disabling both the antivirus and the firewall, but nothing has changed. Also I unchecked the power saver that disables the WiFi adapter. These attempted remedies do not help.
How is it that I have a strong signal and can logon, but have no internet access?
