Hi. Sorry if this question has been asked many times before on this forum, but I haven't been able to find a thread which helps me with this exact problem. I am running a dual-boot between Windows 10 and Elementary OS. When I booted Elementary from my flash drive and started the installation process, the installation wizard was able to detect the various Wi-Fi signals around me and I was able to connect to my main Wi-Fi network. Everything went smoothly, except now that Elementary is actually installed I don't have any option to connect to a Wi-Fi network on the top-right of the screen or in the settings. There isn't any list of networks or anything; just a button on the top-right which says "Ethernet" and its logo looks like an Ethernet port. According to my device manager in Windows 10, my specific wireless card is the Dell Wireless 1550. So far I haven't been able to find a driver for that card which is compatible with Linux. In any case, I don't think the wireless card is a problem since my wireless connection was working perfectly during the installation process. Thanks for reading.
