Hi Alexander,

I only changed the IP since I do not think changing the mask using the following commands is supported:

./usrp_burn_mb_eeprom --args="addr=xxx.xxx.xxx.xxx" --key=subnet --val=255.255.255.0
./usrp_burn_mb_eeprom --args="addr=xxx.xxx.xxx.xxx"  --key=gateway --val=xxx.xxx.xxx.xxx

I'm doing some more tracing soon.

Regards
Craig

Have you changed subnet mask or IP address only?

Changing IP addresses on UmTRX works fine here. E.g. for the network
at CCC we ran all UmTRX's at 192.168.51.xx subnetwork. I've never
tried to change mask, though.

If you want to debug - here is the code which controls networking in
ZPU in UmTRX:
