To prevent giving out your security information and allowing full access to your network, note that many newer wireless routers have a guest network feature
that allows you to assign a secondary SSID and key that they can use, which will only grant them internet access and not access to your entire network. You can also turn off the guest network at the router when it is not needed. You can see a list of wireless routers with guest network capability (along with instructions on how to set it up) here
This was short lived.
The next day I tried the HP (it HAD connected to Google but the person could not access their email ... luckily) - Turned out to have a virus on it.(?WP2?) - some sort of a worm.... It was "infected". I guess maybe that is why the icon in the taskbar was animated?
I had used my E520 (wired) to send a test email to this person (which never arrived) with a read receipt (which was not read) after the HP'd connected with Google;
The ACER cannot connect (I think there's a switch.)
I ran updated AVAST! (full - various versions all u-t-d) and 3 boot scans. (on Optiplex, E520 and Dell LT) All are clean.
Only thing is my printer: (wireless, direct and other).
It is on a wired PC (E520) - USP connection. This computer needs to be physically connected.
The other wired PC (optiplex) can print withOUT being connected. It only connects to the router (Ethernet). The printer does NOT connect to the router at all.
The E520 does not print if it is not
directly connected via USB; however,
the E520 connects to the router (Ethernet) and its file / printer are UNchecked.
The Optiplex has file and printer sharing checked but I do not see any wireless references in network connections. I did not use the printer with the 2 wireless laptops AFTER the person had connected to Google.
1. With everything clean and all my computers being *normal* could there still be something?
2. Is the Optiplex able to print with no connection because of its INdirect ethernet connections?
(Optiplex ETHERNET direct to the router, and the E520 Ethernet to the router.)
(Although the Optiplex WILL print even if the E520 is NOT connected to the printer via its USB (The E520 in that situation will NOT print).
(I'm rerunning full and boot scans on the 3 *possibly* involved PCs.)
P.S. I did manually remove my network SSID and security codes from the infected HP (windows 7) I guess I still should rename the network, and the security code.
