Hmm, somebody has a brand new wireless network...
And...it is unsecured <sigh> You'd think that such products would come with warnings now. Oh, yeah, they do, but you've got to **read the installation manual** to know to run the wizard.
When I started work at my current job I was shocked to discover our wireless access point was unsecured, AND the power and network cables were squashed in the cable cabinet door - an extremely shoddy installation. I have no idea *why* the previous IT company did not bother to secure the access point, but you can bet *that* situation has been changed, and the physical installation environment is also much improved.
That is a very strong signal; I reckon the new network is right next door.
