I bought one of these recently for $5 to have as a spare in case mine ever bites the dust, but I fear it may never work for me. I have BellSouth DSL, and found a nice website with screen shots of how the modem needs to be configured, but the one I bought doesn't have exactly the same screens, and won't let me set up the proper Bridging Port (Says "Cannot create port", or something to that effect). After a bit of research, I fear this may be an old model that's just not going to work. The sticker on the bottom says "WARRANTY EXP APR2001", and below that, "Speed Touch Home Network Terminator" - no indication of whether it's POTS or ISDN. The firmware version is KHDSAA.108. I found another nice website with newer firmware, version .261, which I downloaded, and attempted to upgrade, but when it rebooted, the red light came on solid for a time, then it booted again, and when it came up, had reverted back to the old version.
Anyone know anything about these? Is this thing usable, or should I junk it?
