Call me a dummy, but I am unable to set a password and/or username for guestaccess. Any advice would be greatly appreciated.
The router will usually have a certian amount of guest accesses set up and a password , if you go into the routers internal settings and under the wireless tab there should be some sub menues and one of them is guest access if you select that then you will see the guest password and the amount of guests that are allowed . All the settings can be changed including the password and you may have to enable the guest access depending how your router comes setup.
I just now looked at my Linksys router and saw the settings so while all routers will be different they all should have a guest access tab or sub menu under the tabs.
