I'm giving my sister a router (Linksys E1200) for Christmas. She's got a several-years-old Airport Express right now, and she's constantly complaining about it. She's also pretty technophobic, so there's virtually no chance she would ever buy one herself. (I actually mailed her some RCA cables recently because she was too worried she would buy the wrong ones.) Not sure what kind of modem she has, but I'm fairly certain she's on AT&T DSL, and she lives in Los Angeles. Before I wrap the router, I'm trying to preconfigure it as much as possible so all she has to do is unplug the old one and plug the new one in. (I think I can talk her through that over the phone...) I'm also going to configure a dynamic DNS setup so I can fix it remotely.
But I'm wondering: what are the chances that the new WAN MAC address is going to cause problems with the modem? I haven't seen that kind of lockdown in recent years, but I also haven't dealt with (presumably) old modems or AT&T DSL in recent years. If it could be an issue, does anyone have any suggestions for how I could get the old one on my own? It wouldn't be anywhere on her computer (Mac 10.6, assuming she hasn't upgraded) when she comes home for Christmas, would it?
