Hi, I recently purchased an HP laptop a month ago and it will not detect my wifi upstairs.  It detected it just fine for the first week, now it won't see my router.  My prior laptop never had an issue.

My HP will only see my router when I am very close, and even then not always at a great signal strength.

  No matter what I try - driver update, reinstall driver, etc - nothing works.

My product ID is 00325-81919-55350-AAOEM

My processor is Intel Core i5-1035G1

My network adapter is Realtek RTL8821CE 802.11ac PCIe 

Any ideas on how to troubleshoot this? Thank you.
