I am starting this discussion because I don't have a service agreement with Cisco and I bought (as a private) an 877 with advanced ip services to connect from home through ADSL.
The router works fine and I have a nice zone based firewall in place, but it keeps reconnecting and renegotiating the adsl link.
The company from which I bought the router says that I will be charged costs if the product is free from defects and I return it for repair.
It would be great if someone from Cisco could confirm that there is a bug with the modem firmware before i send it back for repair.
It would be even greater if someone from Cisco could provide a free firmware update for the modem. I understand that installing the firmware is pretty straightforward.
If I send back the router (it is still under warranty) I might end up paying charges and getting the router back as it is, since the defect is very difficult to spot ( reconnects once or twice a day). I can confirm that my ADSL line is decent and that standard consumer models (Linksys, Sitecom) do not renegotiate the link once it is up.
Any advice would be greatly appreciated.
I found some firmware at ftp.cisco.com/pub/access/800
versions: 3-0-33 slightly newer than mine
4-10-9 way newer but file is very small (is it an incomplete one because i don't have enough privileges?)
Any suggestions on which is better ?
I am located in Italy at this time
Probably i will end up tweaking my modem with "service internal" commands if that works and will focus on creating a kron job or EEM script to reboot automatically on a daily basis.when i don't need the connection.
My line has been tested by a guy who said it's fine, and apparently my cheap modems like it too.
Another point might be that i need to earth my shielded ethernet cables with a custom earth plug. The 877's ac/dc adapter isn't earthed.
I will try to post back to give my solution if i ever find one.
One easy one that I would like to avoid is chaining the 877 to a pure modem and keeping only three ports for the internal network.
