Quadra 660av and 605 Ethernet issues

[tattar8]

I'm having the same issue on both Quadras.  The 660av is using it's built-in ethernet with a Farallon AAUI-RJ45 transceiver, and the 605 is using an Asante PDS Ethernet card.  Both are running System 7.6.1.  At boot, the TCP/IP control panel will report a valid DHCP address, but after about 30 seconds, it will revert back to "will be supplied by server".  At the same time, ping on another machine will begin saying "request timeout".  If I set a static address, I get ping replies until about 30 seconds after boot, after which the Mac stops responding.  I've tried connecting it directly to my router (a current-gen Airport Extreme), and through a Farallon Starlet 10Mbps hub.  I've also tried connecting to an old Airport Extreme UFO base station, but nothing changes.  Am I missing something?

You will not get a ip for whatever reason. You best luck is a 10 base T router and look up the ip with another computer then manually set up in tcp/ip settings.  Do a search on internet or here , im sure its been addressed before.  I had to do the same thing with my color classic.  Just been a while on the specifics.

I got an IP from my router (a 172.16.1.x IP address, which my router is configured to hand out), and I could ping it from elsewhere on the network.  The problem is that the Mac disconnects from the network after about 30 seconds and won't reconnect until I reboot.

did you install open transport?  Then use that ip with like 11 where the x is.  make sure you have it set to manual not dhcp or other auto sensing.

Check your Ethernet cable. Install Open Transport 1.1.1 then 1.1.2. I have no problems with machines using DHCP on even older OS 7.1 with OT installed. Do you have Asante drivers installed? On your router did you notice if it shows your computer as connected, if so what speed, full duplex?

I think there's also an option in Open Transport to keep your TCP/IP link set to "always on" versus "when needed."

Could be that the ports (the switch) in your router/DHCP server are going bad. I had very similar symptoms and it turned out my 8 - port Netgear Gigabit switch was dieing.

It seems like that the option in Open Transport was the culprit, I didn't actually try to run a browser or anything (mainly because I didn't have one on that drive).  I booted off a drive with 8.1 on it and ran iCab, and it's working fine.
