The LM2941 regulator in the Linksys WRT54G, WAP54g, and BEFW11S4v4,
has an absolute max input voltage of 26v. I think (not sure) that the
input capacitor is also 25VDC but can't tell from the markings. I
would aim for running it on about 12-15 volts, which seems like a safe
region. The common 19VDC laptop power supply seems about right
including CAT5 copper losses. I run mine on a gel cell (instant UPS)
and slow pulse charger which runs at about 14.4VDC. I wished all such
boxes were so easy to power.
