Product No C5B28EA#2N Error code 45 I make update for software and same problem only Wi-Fi not working Please help me
The Ralink RT3290 802.11bgn Wi-Fi Adapter has major issues with the newer builds of W10.
There are no fixes other than to upgrade the internal wifi adapter to one that has better support for W10, use a USB wifi adapter that has support for W10, or go back to W8.1.
If you want to upgrade the internal wifi card, this is the one I recommend.
Broadcom BCM943228HMB 802.11abgn 2×2 Wi-Fi Adapter, Broadcom Bluetooth 4.0 Adapter HP Part # 730668-001
You should be able to find one on eBay. Search by the HP part number, not the model of the wifi card.
Below is the link to the service manual, where you can find the wifi card removal and replacement procedure.
