when it comes to doing installations over WiFi, I personally never trust it.
Even if the laptop is an inch away from the router, and an inch away from the printer,
Nothing beats good ol'fashioned hardwire connection.
Now durning most wireless printer setups, they ask you to first connect either the USB Cable to the PC, or an ethernet cable to the router
So my question is, what step in the CD setup does the connection drop?
Literally give me a step by step on what happens and I can better help...
so if, as an example, you go to PC 1 and install, and it' fine doing all the step on the CD
BUT then you do the exact samething, with the exact same hook up on the laptop, and it fails, killing both connections
there is something wrong with either the laptop, or the router...
what makes me so sure?
I've been doing setups like this for almost 10 yrs 6days a week 10hrs day
and never had the same problem twice (although some times it is a cable unplugged or the power not on, but I dont count that! lol )
