Since the 4100 was only router with out any wireless nor a faster CPU, these new gen routers run hotter and work well even running at these temps. I have the 857. Runs great. The have faster CPUs and more HW so just nature of the beast that these run hotter. Its ok.
Also you could have checked out a DGL-4500, even though it's not made any more, it was the next gen router up from the 4100 and 4300 that had wireless G.
Let see if we an help you get the 827 doing for you.
