I'd rather have a stable dial up than a flaky broadband for this game. As an extreme example play this game on satellite broadband and you'll complaints about warps from everyone.
Satellite broadband? Yes that is an extreme example. Download via dish and upload via telephone wire? Yes I'm sure a good rain storm would cause warps just like it does for my TV and from a work perspective our wireless networks, one good thunderstorm and we have timeouts and packet losses everywhere.
Stable dial-up yes I guess if your comparing it to no connection at all or a very bad one. But if you can get a stable dial up there is no reason in the world why you can't get a stable basic broadband connection to do the same. All you need is ISP support,switch at the local exchanage and thats it. Router/Modem wise same deal with any hardware. RTFM set it up once and thats it.
If I compare the issues I use to have back in the 90s with dialup compared to broadband it's chalk and cheese, router is rock solid and thats with ADSL 2 which is also being used for VOIP at same time.
