Hi. My name is***** you for your question and the opportunity to assist. Is this a desktop computer
using a USB wi-fi adapter?
Try resetting the neworking protocols first.
Right-click on the start menu button and select Command Prompt (Admin)
At the blinking prompt in the black window type the following commands, pressing Enter after each
netsh winsock resetnetsh int ipv4 resetnetsh int ipv6 resetipconfig /releaseipconfig /flushdnsnetsh int ip reset netshlog.txt
Close the window and right-click the start menu button once more
and open Device Manager. Expand the entry for Network Adapters.
Right-click on your wireless adapter and Uninstall.
Once done, restart the computer and check for a wireless connection.
Thanks. Since it works on another wireless I have more questions.
Is this a desktop computer using a USB wi-fi adapter?
Has the computer ever successfully connected to your router using the wireless adapter in use now?
From your pictures and what you describe it is starting to point to the router as the problem.
Is this a newly set up router or have any changes been made to it lately?
I'm a Comcast customer myself.
Call them and ask if there are any connection restrictions set up on the router. There shouldn't be but it won't hurt to ask.
Did a Comcast technician initially set it up or did you pick it up or get it by mail?
When you have Comcast on the phone have them reset your router remotely.
