The 266 Mhz part has no heatsink, but I've found it to be flakey in "hot" environments if a heatsink is not rigged to it. So... the WRAP boards have 3 "sis" interfaces. With various combinations of usage, one can expect 30 megabit of average sized packets if they kernel is doing the passing. This makes the board an adequate wireless bridge. If userland is doing the packet passing (pppd vs. mpd as a DSL router), I've had trouble getting more than about 10 megabit through the unit. This makes it an adequate DSL router but poor for aggregating multiple links.
