Turns out the owner had installed a few protection items. The antivirus suite had to be uninstalled and the pop up blocker disabled to get the login for the public WiFi. Turns out the machines were fine.
Hi all - I've had a ton of issues with the wifi connection on my Dell XPS 13 9360. In particular, I cannot get my computer to connect to public wifi (like it won't connect at all, no signal). The difference seems to be that the computer won't connect to any wifi that requires a public confirmation or "accept terms of service" or anything like that. The requisite popup will not appear. Before that I had problems with DNS errors, which I resolved by changing some numbers in my IP address (I believe). Really need the help. Thanks!
