A firmware upgrade would probably help, if there actualy where a update to dowbnload...
http://inoviatele.com/Products_Hi/HiBFOCuS_270.asp# this is the only place where there
is any info on this "combo" thing of yours, but of course no firmware, this may be due to
that only the ISP are allowed to update the firmware on your router, since this router is not
for the private marked.
