Could you let me know whether you are restarting the PC to get online or the Wi-Fi modem to connect to the devices?

all devices need this? 

Just the pc?

what pc is it? 

A bit more details can help us to help you

I’m having to restart the PC to get online.  PC was built by my IT guy so I don’t really know how it was put together.  And IT guy can’t seem to find the cause of the problem.

All other devices work fine? 

Built by your IT guy? 

What wireless card is in it? 

What driver is installed for the wireless card?

Is it able to go online if you disable the wireless card and then re-enable it?
