I suspect that the new TFO code hasn't been tested much on mips. Am glad you are doing so! I got my replacement wndr3800s a few days ago, and will put the next build through the TFO wringer (as well as attach a serial console). That said, perhaps your bug report best belongs on netdev where there are a couple people working hard on TFO and at least one has a cerowrt capable box...
