RouterProblems

I have one stationary XP PC connected to DI 614+ router with cable at port1
and one XP Laptop with wireless Lan-Express 802.11b connection.

Internet works fine on both pc:s

Why can't I set up a small network with these comps?

Must I buy a wireless pci card for the stationary PC?

Your problems have nothing to do with wireless v. wired. If both PCs
can concurrently get to the 'net via the router, your LAN is working.

I assume your complaint is that file sharing is not working on
your LAN: there are several possible causes, but the most common
with XP is using ICF. If you have ICF enabled on either PC, turn
if off permanently; if you want a firewall in addition to the router
(IMHO you should), get one that is more flexible than ICF, such as
one of the ZoneAlarm products.

Thanks for the reply..

ICF is turned of, fileharing's still not working.

I dont know much about networking,
but should'nt I assign a IP adress to both comps?

Since you are using a router, I assume that the router's DHCP
server capability it enabled and that the PCs are set up as DHCP
clients; that is normally the best way to get IPAs assigned, since
they will then be in the same IP subnet -- a prerequisite for
file sharing. To check, run CMD and then type IPCONFIG/ALL in
the CMD window (on each PC); it should show IPA=a.b.c.d, where
a.b.c is the same on both and the d's are unique; and, it should
show a subnet mask of 255.255.255.0.

If the IPAs are OK and you have turned off ICF and removed all other
firewall and Antivirus apps on both PCs (at least while debugging),
then check that:

1. Both PCs have the same workgroup name and unique PC names.
2. Both PCs have TCP/IP enabled; best if NetBEUI and IPX/SPX are not.
3. NetBIOS is enabled over TCP/IP.
4. ClientForM$nets is enabled.
5. F&P sharing is enabled.
6. Each PC has a shared non-root folder, with a short simple folder
name and a short simple share name; permissions to that folder
should be set for Everyone to have full access.
7. Enable the Guest account on both PCs (at least while debugging),
with a null password.
8. Make sure each PC can ping itself and the other, using both
ping-by-number and ping-by-name; if ping-by-number works but
ping-by-name fails, then you have a DNS problem and should set
the DNS IPA to match the router's IPA (this usually works OK).

No, sorry, that's not right. Okay, it's right but not in every case ;-)
To explain: Many routers can be configured to give access to the
Internet for any wireless device but not to the Cable-Side of the LAN.
This is a security feature to make it impossible (or harder) for
wardriver to access your LAN.

You should check your router-settings again ;-)

Have a nice day,
Stefan.

Well, acutally DHCP can also cause trouble. There are routers aviable
that provide DHPC but no DNS and other services. It may happen that you
can't access any PC on the LAN by it's name but only by it's actual
IP-Adress.

There is NO reason to stop/remove any Antivirus.

ack. Even if that isn't as important as it has been under Win 9x, you
should do that :-)

No. That don't need to be. In fact, that's a very big securityhole...

Well, I don't think so: If both computers can access the Internet you
don't have to set a ping to localhost (it's own IP or 127.0.0.1 which is
the local PC), since they must have a working lan-connection. To set a
ping to the name could help to find out if Name-Services are running.
Maybe helpful, maybe not.

Just try the following:
Boot up both machines and check their IP-Adresses (CMD -> IPCONFIG
/all). Note them and try to ping the other Computer by it's adress. If
that is _not_ working, you probably have trouble on the router-side.

If it is working, try to create a new account on both machines. Should
be set as an Administrator during the test. Make sure that both are
having the same Name and the very same Password. Then try to connect the
other computer by using the Windows-Explorer and the following adress:
\\xxx.xxx.xxx.xxx\c$ where xxx.xxx.xxx.xxx is the IP of the remote
Computer. If LAN is working right, you should get access to the ohter
Computers Harddrive "C" or at least a prompt to enter your password.

Just let me know how far you came ;-)
