Hi Andy,

Yeah, I tried the first socket with a fine tip iron, but melted too much for my liking, so I took it off with hot air. The second one I cut the center out and stuck it back in after

I suspect you're right in that the network connection is something DHCP related. Here is what did work and what didn't...
- before a reset all, I changed dial code to 140, setup wifi (which asked for SSID/password, and if I use a DHCP server), and forced a connection. This all went well and it connected.
- after a reset all to link the TSN, I ran a guided setup. it asked the usual things, including setting up of wifi. The first time through, it only asked for SSID/password, and failed at "connecting". So I went back and tried again, and this time it asked if I used a DHCP server. I said yes, but it still failed at "connecting". I tried many times, because under a guided setup you dont seem to have a 'skip' option or anything. If it cant connect, you cant continue.
- finally I plugged in ethernet, it asked a different network question (cant remember now), to which I answered "i dont know", and then it connected fine.
