Well, if you put in the bridge mode, you're saving the crap ONT from routing processing related tasks, so you'd be reducing processing and therefore heat, which in turn will extend its crap lifespan.I am not trying the bridge mode stunt at home right now...for if anything blows Up in the onu, which I am sure will one day considering how it’s built, I will be marooned forever. The service here is so slow and poor that they take 6months time to fix it in normal days, I do not even want to know what will happen during a pandemic 😛
