When I want to see if it's hardware I boot some Linux from USB or DVD. No learning Linux either. No install is required. Example advice at http://tips.oncomputers.info/archives2004/0401/2004-Jan-11.htm
2. That was two questions.
a. Hardware. We usually replace the WiFi module if it's failing or use an USB WiFI device.
b. Software. Usually install the maker's issued versions of the drivers. We also remove ANY app that can interfere with WiFi that didn't come with the PC. This can include TORRENT APPS and Antivirus/firewall suites.
A four year old HP laptop with Win 8.1 having problem in wifi connection recently. The wifi symbol in laptop shows it's connected to router but websites doesn't open sometime. At the same time when i try to access wifi using mobile phone the website is opening fine. This means problem is in laptop and not with router or internet connection.
The problem often gets resolved after disabling and enabling wifi adapter or sometimes i have to connect using LAN cable. I think the problem is either with laptop wifi hardware or software.
1) How to know whether the problem in laptop wifi hardware or software?
2) How to resolve the problem in laptop wifi hardware or software?
Looking forward your reply. Thank you.
