occasionally, but not usually. When on public wifi (rare) I just end up piping my traffic through my home swervers using either a SOCKS5 proxy or VPN, depending on what I'm doing.
It's fine, just not fast enough for me. Even image-heavy web browsing can be a pain on it at times. It also usually adds a lot more latency compared to the 5-20ms latency I usually get added when using my home proxy.
