Business Class DSL has been going down constantly. HELP!

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance





I don't even know if anyone can possibly give me any advice. I
guess at any rate, I need to rant.

I consult for a 50 user company. About 3 weeks ago, our "AT&T
Business Class DSL Service" started dropping out on us all the time.
The setup we have is their DSL router (A Small, looks like it's for
home use Netopia brand) with no NAT and no DHCP simply performing the
PPoE authentication and a Sonicwall firewall behind it doing the NAT
to our 5 Public IP's (only 3 are used). The first visit by the tech
had him tell us the router was bad and that our internal wiring was
bad also. He managed to get the internet back up. He left and things
were fine...until the next morning. Down again. Same tech comes
out. This time, he also finds some line problems outside of our
building. He takes care of those, and in the meantime we drop a new
cat 6 cable to tie up the phone lines to the panels inside the
building. Everything looks nice.....for a day.

We are losing Sync AGAIN. The guy comes out again and tells us
that the power in our building is bad and is destroying our DSL
routers. He found something wrong with the line in a different spot
and fixed it. We also hooked the DSL router up to a "Power
Conditioner" on a dedicated power circuit to control voltage
variation. It was good. For one day. Then it went down. A new tech
comes out and we get on the phone with some boss of the region. They
decide to change out the S2 pair and do a "port swap". I'm not into
telco so I have no clue. The next day I come in and the internet is
of course, down. The Cable modem is reporting way different line
speeds. They swapped the wrong port. They messed up with our phone
number. The swapped the right port and it worked. For 3 days. This
time it wasn't dropping sync...just dropping packets. The internet
worked but was horribly slow. A tech came out and put an older, 3 Amp
version of the Netopia Router on. The internet worked....for about 4
days! We are out of the woods!

Today, it dropped. I did some looking into it and found "Wrong
Password" errors. They had randomly changed our password. I got it
changed back and everything was ok for 3 hours. We lost the
connection completely after that. I went out and rebooted the
router. Connection was restored but we are dropping 15% of our
packets. Tech is coming out tomorrow. It's possible that the users
will lynch one or both of us.

It is an AT&T Yahoo DSL 3000/512 line. I called Time Warner to
see about business class Road Runner but they cannot bring it to the
industrial park we are in without major construction. They are not an
option. I was quoted $589 a month for a T1. We are paying $120 for
the DSL line. I brought this possibility up to the president but he
wants to know why after using this DSL service for a few years does it
not work. Why pay $589/month when our $120/month solution was working
fine. I don't know what to tell him. I don't know what to do. Any
advice?

Untill the next day. DSL is losing sync again. Another tech comes
out and tries a 2wire router. We couldn't get it configured
properly. He puts yet another Netopia on and fixes the lines in two
locations around the way.
