iPod touch Not remembering home network wifi as known network.

[cakbar]

I have had my touch for a few weeks. I live in a downtown area, so many of my neighbors wifi shows up, with a few of them allowing entry. For some reason, my touch keeps defaulting to one of my neighbors networks when I turn it on, and will only allow me to log onto my own home network manually. I have WEP turned off on my network but it does only allow registered MAC addresses to use it (in theory). My touch is one of the registered addresses. I also have a macbook, and it doesn't have the same problem. I have tried telling my touch to "forget" all the other networks, and it still doesn't recognize my network as "known". I was under the impression that the touch would log onto the last network used if it is available.
Anyone have any suggestions.
Thanks

PS, wireless router is a relatively old 802.11b, with a fairly weak signal. Could it be that by the time my touch has detected the signal, it has already made the decision to connect to another network?

I think your last sentence there solved it, it probably connected to another network and then found a weak signal after

dont quote me on this but I also think the touch defaults to a none encrypted connection, you could try going into the neighbours connection settings on the touch and click on forget network that could help
