Yup, he's a nerd and most likely 'just happens' to have those pieces lying about... - nothing to do with 'price' :/
Also, the word 'router' has gone though a lot of 'actual meaning' changes in the last few years... eg..
(yes, this is what the confused PC shop calls them!! :roll:
- 'router' or 'switch' - I forget, one routes packets by IP to the ONE PC it is for, the other just sends the packets to ALL connected PCs..
- ADSL router - can mean ADSL modem, may have ONLY ONE Ethernet output, telephone socket input!! - may have NO modem, you just plug the output of your modem in, and get 5 rj45s out...
- cable router - Its just a splitter for the output of your cable box, for 5 rj45s out...
The next problem with home made, is the ISP going to 'recognise' it, so its services can run properly???
- then again, I guess nerds wont be using the 'awful' premier BB provider, in preference for one of the 'non-consumer ' ones... :)
