I picked up a 2wire 1701HG DSL modem/router/WAP this weekend cheap. The power supply (or AC adapter) was missing. Google indicates the factory power supply is really dodgy. A replacement 2wire 1701HG power supply costs anywhere from $13 to $25.
But it turns out the Sony PSP’s AC adapter works fine with the 2wire. Sony’s power supply is common and dirt cheap. Normally I prefer to get higher amperage when buying replacement power supplies, but the connector is a little weird. The PSP box is readily available, so I’ll go with that, at least for a while.
Now I just have to configure the 2wire in such a way that I don’t have to redesign my whole home network… That’s a project for another day. The main thing is getting a quality replacement 2wire 1701HG power supply, so the unit itself will be reliable.
