For a while now I can't connect to steam, because it is blocked on the wifi network that I am connected to. Because of financial problems my family decided not to buy broadband, so I am stuck with the free wifi of the shop opposite my house. Unfortunately I can only access websites on chrome and skype. Steam is put into offline mode. I tried several proxies, however they either only unblock filtered websites or don't work at all.
I tried several solutions from youtube and always end up with steam not being able to connect. Through connecting through my phone, initiating a download and disconnecting I found out that the download servers of steam are not blocked, but everything else is.
Can anyone help?
