We recently got a T1 line at our company, but the problem is that it keeps dropping out once and awhile. At&t states all is okay at there end, and when the T1 drop (I lose my signal or connection to email or internet)thats what I mean by dropping out..I try to ping the addresses with no luck, but when I try it from another station it will be okay. Mine will come back eventually?? all stations are hooked into the same switch and go out to the same router so why would one lose connection and not the others?? they are different NIC's but that should not make a diff..we also have a 56k line going out of the same switch as the T1 line, when I lose the T1 line I still have access to my HP3000 server located in Va Beach..so I can go out one way but not the other?? any suggestions will be greatly appreciated, if someone needs any further info I can supply it gladly
Do any other stations lose the connection too?
The T1 line equipment often has an error log so AT&T should be able to review that (sounds like they might have).
The next time that happens you should try to determine the connectivity that you have.
1) Can you ping Internet addresses, by IP address (not talking host name)?
2) Can you ping local addresses by IP address?
How are your IP addresses assigned (manual, local DHCP, remote DHCP, other)?
i'm assuming that from your router your internet connection goes through a firewall before hitting your internal network, yes? give as much detail as you can concerning what you've got that's between the router and your internal clients. also, are you running multiple internal subnets and if so are there clients on the same subnet that can access the web yet others on the same subnet cannot? i've seen issues like this resulting from child process limits being set low on 'nix boxes that have the internal clients routing through them. give us some details and we'll see what we can come up with!
