Small tip if you are trying to updated or regrade the firmware in this type/make router e.g. most of the conexant chip based cheapo routers like my Origo.
Only use Internet Explorer when trying to use the Image update url, not Opera and possibly Mozzilia or theres a good chance it won't work as it was never ment to work with them. If you do try it, on rebooting it will constantly fail with the Load module error and possibly loose some settings eg SNTP if set, requiring a Default settings rest to fix it.
