I recently purchased a Billion 7800DXL router to replace the 7800N I had before (I think the ADSL port blew out in a recent wind/snow storm). I noticed the router had the 2.32e-dl6 firmware, and I went to the main website to download the latest for this router, which was just marked as 2.32e.
After updating the router with the firmware I downloaded, my router now only shows 2.32e. I'm wondering if I've managed to downgrade the firmware, although I can see no signs of any newer release. I notice the dl6 version is mentioned on the forums a few times though.
I'm wondering therefore:-
1) Is 2.32e-dl6 the newest firmware and should I use it on the box?
2) What is the difference between 2.32e-dl6 and 2.32e? Is it significant?
3) Where can I download 2.32e-dl6 from? It doesn't seem to be publicly available.
If anybody could help me with this, I'd appreciate it

Thanks
