My router has a "Guest SSID and Main SSID" is it ok to leave the guest SSID for outsiders?
Also how do i extend our network to the front of the office. It has very week reception. I thought adding a access point would do it, but then its like a separate network. How do i use the same one all over on the office?
If the signal is weak, best practices would be to use wireless access points. It certainly doesn't have to make a new network. If it has DHCP, turn it off.
What do you mean by leave the guest SSID for outsides? Who would be the outsiders? Are you saying you would allow outsiders to access your network?
