Simple basics first ... is his monitor on
modem restart it
Little more info would help, like what the setup is at your house. So you have a modem, how about a router and/or switch?
Since you get internet connection, the issue most likely is residing on your dad machine. Does his internet connection state "unidentified network" possibly?
You can also try to power cycle the devices:
First power off/shut down all computers in home -
1. Power off router and/or switch
2. Unplug modem for 30 seconds, plug back in, wait for modem to come online by verifying the Internet light is solid.
3. Power on router and/or switch.
4. Power on all computers and devices one at a time.
Switch cables. IF your computer doesn't come online, it's the cable
sounds like daddy's got a bug to me. y not just call ur isp ? ,,,that's part of what u pay them for,,,
They don't give free service for home networks, only the basic internet connection coming into the home. I know I work for one.
check the internet connections in control panel and make sure everything is ok
there are too many variables.
is it wifi? which operating system? does it work if you are not connected? etc
Yup dat aught 2 dew it.
Not enough bandwidth for two computers basically your internet is too slow for two computers
internet speed fluctuates like in evening hours and weekends you'll experience lesser speed
