I have a wireless broadband connection through a router and wireless modem. Everything works fine in Windows. However, in Ubuntu on the same machine, websites seem to take longer to start loading. I think the DNS lookup is slow. I think https sites may be slower, as I just can't log in to Gmail.
I am also using a mercurial repo with remote origin, and it takes forever (like 5 minutes) to push one small change. I think it is because it has to communicate through https multiple times. Should I change my DNS server? I've seen that I don't have these problems at my work network (they have another DNS server). This happens with the IPv4 settings being automatic (dhcp). When I change it to automatic (dhcp) addresses only, and add Google's 184.108.40.206 in the DNS servers, it still takes forever.
Why is this happening?
