Months ago, I repaired a computer for someone. At her house, I found that the (inexperienced
) customer had plugged the phone line into the "Internet" port (which was actually for connection to an external broadband modem with Ethernet) on a wireless access point (without an inbuilt broadband modem).
Certainly, this setup would not work and fortunately, the router was not damaged by that condition, because Pins 4 and 5 (which were connected to the phone line) were not internally connected in the router.
I remember seeing a 3Com network card with a "No Phone" symbol on it - I think all wireless access points (without a broadband modem) intended for home and business should have a "No Phone" symbol on an Ethernet connector labelled "Internet", "Broadband", "Modem" etc.
