Does not take much to interfere with a wireless signal and those bars are not all that reliable per se.
What wireless network adapter are you using: built-in, PCIe, USB? Make and model?
Are you sure that only one network adapter (wired or wireless) is enabled on your new computer? One or the other - not both.
Who has full admin rights to your home router? The router's logs (if available and enabled) may provide some clue.
And, also with respect to the router, you need to work with the router's admin to ensure that your network adapter is properly configured for wireless connectivity to the router.
On your new PC - are you able to run and post the results of "ipconfig /all" via the command prompt?
I'm pretty sure my wireless network adapter is built-in. I don't know what make and model it is and I don't know where to check.
Only have one network adapter is enabled.
Everyone in my house has full admin rights to my router, because it's wireless. I don't know where to check the router's logs.
I don't know what that means. (Sorry)
