I inherited a Linksys BEFSR81 8-port ethernet router that a previous owner connected the wrong power adapter to. There is a 14 pin surface mount IC identified as "U7" in the front left corner of the board which had the magic smoke let out of it. I assume that this is just some cheap bit of glue logic, and would be worth attempting to replace before just trashing the whole unit. Unfortunately, the chip is so badly burned that I can't get any identifying numbers off of it. Everything else seems in good condition, and the unit even lights up and displays the config page correctly (but won't route any packets), so hopefully this will be an easy fix.
Does anyone have access to a schematic for this unit, or have one that they could crack open and have a look at?73, Bob Weiss N2IXK
