HP Pavilion 15 laptop not connecting to WiFi

[Ankur24]

Product name: HP Pavilion 15 Notebook PC; Product number: E3B55PA#ACJ ; Serial number: [edited] ; OS- Windows 8.1 Single Language 64-bit ; WiFi Driver Version: Ralink RT3290 802.11bgn (Wifi driver Version 5.0.37.0) 

I cannot connect to any WiFi network, be it in my own house, my relatives house, or my university. This issue persists since I bought laptop in 2013. I have re-installed and ran the updated WiFi drivers by going on HP's drivers page for my laptop model, without positive results. Restarting the WiFi routers hasn't helped as well. Please suggest me a solution to this issue.

Your machine is an  HP Pavilion 15-e015tx Notebook PC  and yes it does have Ralink RT3290LE 802.11b/g/n 1x1 WiFi and Bluetooth 4.0 combination adapter part #  690020-001.

Please try to do a CLEAN install (uninstall the old one, reboot) using the following software for Wifi

and for Bluetooth

I have installed the softwares for Bluetooth and WLAN as you mentioned. But, I haven't been able to connect to public and home WiFi after it as well. It connects to the wifi hotspot created by my mobile phone, but shows limited connection even though I'm able to browse normally on phone. I suspect there is problem with the WiFi card in my laptop. If that's the case, what are your suggestions?

P.S. I have also gone through the archived HP Community page on troubleshooting WiFi connection issues (resetting TCP/IP, resetting winsock, disabling option that switched off wifi adapter for power-saving purposes, re-installing latest drivers, checking ethernet connections, manually entering laptop's IPv4 and DNS addresses for connection) Despite this, I haven't been able to connect to WiFi
