I live in IIT(BHU), Varanasi, India and we have internet connection through ethernet and WiFi. The WiFi network uses 802.1X security and we have Protected EAP authentication. As per the guidelines provided to us, we do not require a CA certificate, and have to set inner authentication to MSCHAPv2, and PEAP version to Automatic. Anonymous identity, username and password have been provided. However, while I am easily able to connect to ethernet using these settings, the WiFi network does not show up in the WiFi networks' Select Network menu. I am using an HP Pavilion notebook with Ubuntu 18.04 LTS and the WiFi driver is RTL8723BE PCIe Wireless Network Adapter.
Another issue is that other WiFi networks have a significantly lower strength on my PC than my smartphone or when I use Windows 10 on the same PC, in case it is relevant.
What do I need to do in order to solve this?
