BT Business Broadband Connection by Router

Hi

We have a baffling problem, which hopefully someone may have an answer for.

Our network comprises of a Windows 2003 Server, and 12 Windows XP
Workstations, connected by a mix of Wireless and Cable. We can access the
BT Business Broadband fine using the Alcatel Speedtouch "Frog" USB Modem
that came from BT, and this connection is then shared with the workstations.
Our problem is that when using a ADSL Broadband Router, we can connect, and
browse the web for between 2 and 4 minutes, then we loose web access, and
crucially we then cannot get into the routers web configuration browser
page. If we switch off and restart the router, we can access the
configuration page and again can see them web for 2 to 4 mins. With the
broadband phone line un plugged, we can access the configuration page
indefinitely, but as soon as broadband line is plugged in and connects, we
cant.

IP addresses are assigned by the W2k3 DHCP server, the Server has a static
IP, the ADSL Router has a static IP, and the wireless router has a static
IP. All IP Address are using the same subnet. We have tried taking the W2K3
server out of the equation with no joy. We have tied two different ADSL
router, again with no joy, both routers work fine at home. User names and
password have been confirmed correct by BT. VPI is set at 0 and VCI at 38
Encapsulation is set at PPPoA VC-MuX, the ADSL routers DHCP server is turned
off.

BT are next to useless in providing a solution, and say that as it works
with the Frog, it must be us.

Any suggestions or pointer most welcome.

Are the home and business lines on the same exchange? It could simply be
some hardware incompatibility. If they are on different exchanges then
there could be different equipment at each exchange.
Try upgrading the firmware on the routers (are the routers both the same
brand?).
Have you tried the router plugged directly into the master phone socket
(no extensions, filters or phones plugged in)?

We're having trouble with a new line at work where a usb modem connects
fine but a test router (cheap thing) syncs but cannot authenticate. The
router in question is a Connexant chipset. I've have seen problems with
Connexant chipset routers connection quality degrading over time but that
was over the course of days or even weeks, not minutes. There is a far
better router due in the post soon so we will just wait.

What on earth are you on about?

Did you reply to the wrong post by mistake (having not quoted
anything, I can't be sure whether you thought you were responding to
something else).

He hasn't said anything about multiple lines at all.

You should have gone with the BT managed router and chose a Non Nat
solution, they supply a router and it needs no setting up, I would say we
need to know the name of the routers you are trying, I setup a few BT
managed routers, on a 60 pc network using Demon 2mb ADSL and they work fine,
I had loads of problems using a normal shop bought adsl router,

Ronny

Ronny,

The routers are a Zoom X5, a 3com and a Trust Adsl router (not brilliant
routers I know, but OK)

Things worked fine for 10 day with the Zoom X5 and then BT inadvertently
cancelled the account,when they reset things up 5 days later its all gone
pear shaped, BT insist the line is OK as the Frog works.

If you took the time to read the post yourself rather than jumping in
full of criticism at somebody trying to help out you'd probably come
to the conclusion that he was relating to this:

I had loads of problems with the Zoom X3 on a buisness account and a
netgear, are you setting the zoom as a nat router? ie it has a fixed ip from
the connection then uses dhcp to assign internal IP address's, using the
10.0.0.x range for a small buisness, do you have multiple IP address's?.

If your struglling I would sugest asking your ISP if they can provide you
with a BT managed router, these are great, go with the non NAT version and
use 2 network cards in your server, then use ISA server on the windows 2003
box

If you need any help just give me a shout

Hi Ronny

Thanks for your reply, the router(s) are set up using NAT for security, the
IP address of the router is 192.168.0.100 the DHCP scope on the server is
from 192.168.0.2 to 192.168.0.40 we are moving office in December, and will
be buying a Cisco VPN all singing all dancing router then, but in the mean
time wanted to experiment with the VPN etc now. I did have everything
working fine with the Zoom X5 for ten days the BT inadvertently cancelled
the account,(we had gone from the 1MB account to a 1MB account with Static
IP address) ever since they screwed things up and eventually admitted the
error and reconnected the account the router option has not worked. What
really puzzles me is the fact that with the broadband phone line
disconnected from the router, it functions fine as a hub/switch. But within

2 mins of connecting to the phone line, I can no longer access the router
configuration page in IE6. This makes me think that somehow the BT side is
changing the routers static IP, but quite how I don't know. I have tried
taking the server out of the loop and running static IPs on the workstations
but get the same problem.

One other thought, we are about 2.5 miles from the exchange out in the
back-of-beyond could it be that the router is less tolerant than the Frog on
line quality?

I know we are using a cheapo router, an that a Cisco would be possibly the
solution to our problems, but I hate the fact that it did work fine before
BT screwed us over.



Over to you

Cheers in advance

There are two many variables here to put your finger on the problem.
I would suggest you use the router connected to the phone line and
hook up a single PC to determine if the connection will stay up.

Then build up the network one step at a time until you discover where
the fault / problem lies. You can then concentrate on finding a
solution to this failure.

As Robin pointed out, the OP did say something about multiple lines hence
the content of my post.
