Count me for another. Though I don't complain about the speed, the

I have been experiencing a lot of problems with the Home 1000 BSNL
Broadband plan since two weeks ago.
My configuration:
OS: FC3, user space patched, stock kernel.
Modem: UTStar
Host obtains IP address from modem through DHCP
I was initially using RP-PPPoE with no problem. Two weeks ago, RP-PPPoE
was no longer able to establish a connection with BSNL.
Soon after, an engineer from BSNL showed up and configured the modem to
be the PPPoE endpoint. RP-PPPoE was disabled. Despite some opinions to
the contrary in this group, the engineer confirmed that BSNL supports
this configuration. He also confirmed that nothing had changed at the
BSNL end.
The connection has never been good. I have almost never been able to
connect to Google or Gmail after that. Most other websites don't work
either. There are timeouts waiting for the connection to the server.
FTP seems to work. ping works as does Yahoo Messenger. DNS resolution
is ok. POP doesn't work.
To troubleshoot this problem, we replaced the Linux desktop with a
Windows laptop. Internet Explorer was able to connect to various
websites. Speed was bad and the BSNL engineer is trying to investigate
why. I can't explain why Windows works but Linux doesn't. Both use
DHCP to obtain an IP address from the modem.
I'm not sure what the problem is. We've tried with the iptables
firewall disabled -- no difference. We've setup NAT on the modem to
forward everything to the host -- no difference. BSNL does not know the
cause of the problem.
The modem reports its connection status (LAN side and modem side) as
good. netstat shows that the default route is to the modem.
I am planning to use Ethereal to see what is actually happening on the
Ethernet.
Is there a way to snoop on what is happening at the phone line end of
the modem?
BSNL's incoming mail server seems to have some sort of overzealous virus
checking turned on. Most emails from Gmail are bounced saying that
there is a virus in it. From the bounce message, it appears that
Sancharnet.in is uncomfortable with the character encoding used by
Gmail. BSNL's helpline does not know what is going on and
postmaster@xxxxxxxxxxxxx didn't bother to respond.
I was very satisfied with BSNL for the first two weeks. It has been a
disaster since.
