OK BEAR WITH ME I AM A COMPUTER DUMMY. WITH MY TYPE OF HI SPEED INTERNET FIOS 15/5 CAN I USE A WIRELESS PRINTER COPIER SCANNER AND FAX?
Yes, the Verizon provided FIOS router is a wireless router.
Check the documentation of your printer/copier/scanner for instructions on how to connect to a wireless router.
In general, your printer/copier/scanner will need to know the SSID of your router and it's encryption key. Assuming you haven't changed these settings in the router, you will find the SSID and WEP key printed on the label on the underside of your router.
Keeping what Anti-Phish has said already, I will add that there a several reports of difficulties with wireless printer setups (Brother being one of the most often mentioned) having difficulty connecting. So you may want to search the brand you're thinking of buying to see if there are any reports of connectivity issues.
Technically, there shouldn't be any issue ... the technology is all standards based ... but a few printers seem to have issues.
