Could anyone help?

I have an XP PC and and iMAC whic I am trying to share over a 4 port ETHERNET ADSL Router/Modem (Connexant AMX-CA61E). The Router has 4 x 100/10 Ethernet ports and 1 x USB. The PC is enabled and connected to the router ok via the USB port. However, I am having diffs getting the iMAC to connect to the WN side of the ADSL router.

I can Ping the Router from the iMAC and I can Ping external Web addresses from the iMAC also; indeed have used Traceroute to various addresses across the globe also. So cannot understand why I cannot browse and connect to internet sites from the iMAC :-/. There are conflicting details from my router manufacturer and other users as to whether the ethernet cable should be "straight throuh" or "crossover". I am using straight through currently, could this be the problem?

Any assistance very welcome.

Regards

When connecting a computer to anything other than another computer, you use a STRAIGHT THROUGH cable. When connecting two computers together you use a crossover cable. The confusion usually comes from wanting to connect two non-computer devices, like a broadband modem and a router.

I don't know too much about Conexant products, but it's possible that having the PC connected to the USB port (and working) may mean that the router/modem is only configured to use the USB port.

What about using ethernet between the PC and the device? Since you know the PC can get online through the USB connection, plugging it into a router port may tell you whether or not the ethernet part of it is working.

Try entering the IP addresses of your ISP's primary and secondary Domain Name Servers (DNS) on separate lines in the Name Server Addr. box of your TCP/IP control panel (if you are using OS 9) or into the Domain Name Server box of your Network Prefs panel (if you are using OS X).

Many thanks for your advice folks, I removed the PC from the USB port and connected to one of the ETHERNET ports. It still wouldnt work.

However, I checked the "obvious" again and lo the ETHERNET cable was below spec. It was electrically continuous but didn't pass the CAT5e spec on attenuation. One repair later and it is all ok now. Incidentally, I also tried straight through and crossover - they both work! I suspect the ROUTER does an internal adjustment.

Once again thanks for your help.
