my DSL-302G overheats...
Is this modem supplied to you by your DSL provider?
If so, call them and let them know becasue it is there responsibility to replace it.
If not, I have read numerous threads from other forum sites and it is very common that they overheat. The manual states to give it plenty of "Breathing" room but even with that followed people have overheating problems. The general consensus is to buy a different type of modem/ router. Hope this helps.
