Why Wont It All Work

Sorry to bring this back in again but I have been trying for weeks to get this to all come together.

Layout - I have a modem/router (supplied by my ISP - Alice here in France). It has both Ethernet and WiFi capabilities with the WiFi set up via a PCMCIA card into the modem router. Link will take you to a French site but you'll be able to see the layout.

From the M/Router - I have 3 PC systems connected by cabled method - all work great and see each other and the Internet Connection on each is very good.

Elsewhere - I have 2 PC's which have PCI WiFi cards. They are able to see each other but not the network.

The M/Router has an IP of 192.168.1.1 and this is the range I have used for the 3 PC's connected by cable.

The strange thing is that the PCMCIA card in the M/Router shows an IP of 192.168.3.1. I have pinged the 3 pc's and the PCMCIA card and the M/Router and they all deliver spot on returns.

The 2 PC's with the PCI WiFi just will not see the M/Router or the network. They show connected in the sys tray but they do not see the network. I have tried to use the Gateway as both 192.168.1.1 and the 192.168.3.1 IP addresses.

The 2 PCI WiFi cards are set up with no encryption, on an open basis and Ad-Hoc. The Profiles are the same on each and the IP addresses are Manually Configured.

No matter what I do I cannot get the 2 PCI WiFi systems to get onto the network. Any ideas would be very gratefully received.

I would have thought that because you are using a modem/router + wireless, that it should all be set up in infrastructure mode rather than ad-hoc ?

Thanks - I had it set for ad-hoc but that didnt do anything either. I'llc hange it back again and see what happens

No good - I changed it all back to infrastructure and its still the same problem

Does the whole setup have DHCP enabled for everything ? I'm thinking by the look of it that the PCMCIA is getting onto a different subnet for some strange reason (if thats correct terminology).

If you run ipconfig /all at a command prompt on all the machines does anything strange appear?

Maybe it is an MTU problem. Try to find a setting in the router for MTU and change it to 1,000 ... if it works then increase it to 1,400 and leave it at that if it works. Beyond that a search in google indicates Tiscali also supply this modem including this page click here otherwise search google for

Triway router

and see if you can find any help.

HI - DHCP was used but I manually assigned as I have been trying different IPs. have pinged all machines, including the router and PCMCIA (which is on the 192.168.3.1 range) and they have all pinged perfectly except the 2 systems with the PCI cards installed.

Sorry - but you have lost me with MTU. What is this and where would I find it.

Cheers

As I don't know your router, I can't tell you where exactly (Maybe in WAN settings) but if you log into the router interface you'll have to look around to find the MTU (It's probably set to 1500 at the minute).

If it's not that I think it might be the PCMCIA having IP address 192.168.3.? and not 192.168.1.?

I'll take another look at the router interface and see what I can find.

This is the BASIC part of the WLAN Set Up screen:

IP Address : 192.168.1.2
Subnet : 255.255.255.0
SSID : HOME
Channel : Channel 11

You will see that I have changed the IP address for the PCMCIA to the 192.168.1.X range. After doing this it didnt Ping.

This is the WLAN Set Up Advance screen:

Beacon Interval : 100
RTS Threshold : 2347
Fragmentation : 2346
Preamble Type : Long
Auth. Type : Open System
Tx Rate : Auto
AP Visible ON

This is the WEP part of the WLAN Set Up screen:

EncrypType : NONE
Key Format : Blank
Key Select : Blank
KEY 1 : Blank

There is no sign of anything that says MTU.

One thought occurs to me - I've connected the Router to the main PC via Ethernet. Would it be an idea to uninstall everything and reinstall via USB connection.
