Hello,
My Compaq Presario CQ57-426SA Notebook PC laptop has refused to connect to any wireless network for the last 4-5 days (works fine on ethernet), have owned for 3 years or so and never had a problem before. Wireless driver is Ralink RT5390 802.11b/g/n wifi adapter and says is completely up to date and working. So far I have tried:
- updated/reinstalled/rolled back wireless driver
- tried resetting Winsock, IpV4/6,
- disabling windows defender/firewall
- deleting my VPN, - DNS flush
- booting in safe mode with networking
- run Windows repair (all in one)
Nothing has worked so far, any further suggestions very welcome!
