Cant ping default gateway aix 53 07 new install

I just reinstalled a fresh install of 5300 07 on an old 44p model 170 , after installing I set an IP Address on en2 and I tried to the ping default gateway, no response. I tried a

startsrc -g tcpip

... and then I can ping the default gateway. I broke the ping and tried again to ping. I cannot ping the default gateway, so I restarted TCP/IP and the same thing happened. I can use ping once, I cannot telnet.

In my errpt -a few src errors failing to load modules, which seems in line with services not staying up.

I am thinking the firmware level may not be right for this old machine to handle 5300 07 tl , or maybe just this machine cannot handle this tl level.

Any help would be appreciated
