Thank you for reply.
I'll admit, I found Gargoyle looking for something to monitor my kids internet usage. I had an old WRT54G V2.2 in the cupboard that's had all sorts of firmwares on it. I ran up Gargoyle on it to see what it was like and if it did what I wanted. After 2 hours of operating I figured it was and loaded onto my WR1043ND. Then over the next couple of days had nothing but family telling me that their internet wasn't working
I've since put back the WRT54G and for the last 3-4 days it hasn't skipped a beat. I could probably just leave that there, but would like my N wifi back for streaming etc.
I have no idea building my own distribution, so I guess I'll let the WRT54G do the work for the time being awaiting the next version for the WR1043ND.
Thanks for feedback again.
