Thanks Tim I agree with your comments. I initially looked for Bridge mode settings, but this is not mentioned at all. The instructions are to disable the DHCP in the proposed switch (Bob Lite, the downstream router), so this should just leave the Netgear (upstream router) to handle IP addresses. Same result?
The final step is to “change the downstream router’s LAN IP to an unused IP in the same subnet as the upstream router.” I tried to change the Bob IP address to a number within the working range of the Netgear. This range seems to be 2-254. On reflection it doesn’t seem to be right to use “99” as the addresses are dynamic (if that is the term) and will change to say 192.168.1.5 next week when some devices are inactive. It’s the devices I plug into the ethernet ports that will need dynamic addresses I think. And I don’t really know what a “subnet” is. Another reading of one of the more lucid descriptions gives a different slant - I’ll try it out tomorrow. That is, to change the network IP address to one OUTSIDE the range used by the upstream router (but not numbers 0,1 and 255). But is “256” a valid number in this context? Most examples I skimmed used “2” as the address for the modified modem/router, but I have numbers 2-15 in use at various times. Looks like I need to spend some time reading the Netgear support documents - not an easy task. BTW - looks like a typo - or a real mistake - in my original text. I thought I changed the Bob address to 192.168.1.99; not “169”.
