That same as connecting all to router and then connecting router to modem.
What is the switch going to do here, if router can connect all to one ?
Just dont want to waste another 50$ in a switch and then throw it, if it doesnt solve it.
no attach all computers to switch and switch to modem.....
Umm, not sure, what you just said.
Well, I also tried connecting the modem alone in a 2nd power outlet and then connected the PC to other power outlet and tried, but as soon as the ehternet cord got inserted, the modem DSL was gone.
It sounds like the power to me. Swap out the desktops and use PC laptops using battery power if you won't move your DSL model to another outlet in another room and use a wireless setup. One outlet for all that is just wrong.
