No internet connection

[qyiet]

I use a 802.11b connection back to my ISP. They own the wireless hardware that makes the connection, all I get at the end of it is an ethernet cable. No PPPoE to worry about.. just plain ethernet with a public IP. I'm currently running this into a router, but I want to replace the router for several reasons.

I want to use my G3 OSX box to do the firewall/nat but I'm having an odd error when I try to get it setup. The ethernet which works fine to the router dosn't when connected to the G3. I plug the network cable into the built in ethernet, and the G3 detects the network cable is there, I force the IP address/subnet mask/gateway/dns to the correct IPs (same as the router) and I still can't ping out. I get "host down"/"no route to host" messages back from the ping to the DNS server (which does respond to pings normally)

I tried forcing the ethernet to run at 10mbps/half duplex (what the router detects and runs with) still no go. I didn't mess with the MTU settings because I don't know how that affects things.

Plug the ethernet cable back into the router and we are away in seconds.

Any suggestions about where to go from here?

Perhaps, your ISP authenticates by MAC ID? Have you tried with any of your other computers on a direct connection? If they don't work either, then I would contact the ISP, to make sure they don't authenticate MAC ID, or that one of their devices doesn't need to be reset to delet the previous MAC entry from their ARP table or DHCP Server, or something like that.

Thanks for the quick response fezzikjr. I contacted my ISP, the don't use MAC auth, but the radio binds to the MAC address of whatever is plugged into it when it boots up. I did restart the radio, I'll go through the power down/up procedure more carefully this time.

I'm not at home at the moment, I'll test it when I get back tonight. Thanks again for the quick response.

I did restart the radio, I'll go through the power down/up procedure more carefully this time.

The power down sequence is, obviously, not essential.

As far as the power up sequence is concerned, I strongly recommend the following sequence:
1. Modem (or radio, whatever), wait at least 1 minute for it to synchronize with your ISP.
2. Router (if any), wait at least 1 minute for it to synchronize with your modem (or radio, whatever).
3. Computer (PC, Mac, Linux-Box, etc), wait at least one minute after the device has fully finished its "boot procedure", and you don't have any hourglasses or spinning beach balls of death.
4. If it still doesn't work, reset your TCP/IP settings to obtain automatically, rather than the static ones you had previously entered, save those settings. See if TCP/IP will pull a new IP address, etc.

Hope this helps. ;-)

Good luck, and happy surfing!
