I have a friend who has switched from ADSL to fixed wireless access. They have a Vodafone SHG1500 that doesn't seem to have much in the way of configuration options (they'd like to use it as an AP). I've seen discussions saying that network settings can't be changed except by Vodafone when connected to their network? No OpenWRT option listed at http://wiki.openwrt.org/toh/sercom/shg1500. Seems a waste but are these devices just unusable outside their original purpose?
