T1 Networking Issues

A customer has a T1 line running to her home (for whatever reason). She is
using a wireless router to share the Internet connection. I attempted to
correct the first issue I saw which was an IP conflict. I requested a new IP
and received the same one back (which was already allocated to another PC). I
went to the other PC holding the conflicting IP and he lost the Internet but
I repaired the connection and he was back online. I went down stairs to her
other PC and it wasn't apart of the workgroup (even though it was configured
to be) and the administrative privledges denied this PC from the resources. I
went into the router and reset it and manually started giving each PC a new
IP and we were right back to were we started. One PC had the Internet the
rest were conflicting.

I ended up passing the issue back to viox since they configured it in the
first place and the customer was starting to get irritating. Anyway, what
else could I have done to correct these issues, anything I could have done
but didn't? I would really appreciate any possible solutions and things to
look for so, the next time I experience a T1 with the same problems, I will
know what to do vs. losing money.

thanks
 
What kind of router? Is there a separate CSU/DSU box that is the uplink
input to the router? Why are you using static IPs? DHCP would be
preferable and simpler.

Yes

Re: Why are you using static IPs?

I thought I would give them all one of their own. I noticed that PC 1 had no
IP so, I requested one. I then noticed PC 2 had the same IP as PC 1. I tried
to give them one manually meaning, requesting one from DHCP, no - I didn't
physcially assign them one myself. Sorry for the mix up there. I suppose I
should read up on T1 networking but, it would still be nice to hear what I
could have done.

Thanks

BTW: ALL PC's were using XP Home
 
BTW, login into the router and write down how many IP address are usable in
the DHCP pool. Check to make sure the all the PCs are set to obtain IP
address in TCPIP configuration. Then turn off all of all computers and
router. Turn on the router first and wait about a minute or however long it
takes the router to fully come up. Turn on only one PC at a time and make
sure it gets an IP address and you that it can get out to the internet. If
that's good move on the next PC and do the same process.

If the DHCP continues to give out the same IP address which is very odd
(unless a bug in the software) then manually give the PCs a static IP address
from outside the range of IP addresses of your DHCP server. If there are only
3 PCs in this network it does not hurt to use static addresses. This issue
your having has nothing to do with T1 and as long as the circuit is up and
your router is natting you should be fine with that part of the connection.
