RBR50 Cannot change DHCP range or IP Subnet
Since I upgraded to firmare V2.7.1.6 I'm having some problems... My router seems to have its LAN interface configured with IP subnet 192.168.1.0/24 and the router's address is 192.168.1.250 The...

The start and end of the dhcp range are parameters. Maybe it would be possible to set them from the telnet interface. i.e.
config set dhcp_start = 192.168.1.2
config set dhcp_end = 192.168.1.99 (or something)
config commit
and there is lan_ipaddr, which on my Orbi is lan_ipaddr = 192.168.1.1
I just realized that while I have several soldering irons, I have no device with an RS232 port. Does this mean U-Boot is not ever in my future?

I only just discovered the telnet interface... and yes, this did indeed allow me to fix the problem!
config set lan_ipaddr=192.168.1.1
config show
will dump all the current configuration info and I spotted a few other bugus things (e.g. the netbios name was set to some garbage for me)
NOTE: For those who don't know about this, you go to the following URL:
and click the 'enable telnet' box then you can log into the router's management command line using
telnet 192.168.1.1
Obviously substitute the correct IP address for your router
