R7800 cannot administer over ethernet cable
I am trying to install new firmware on my new R7800. Unfortunately I don't seem to be able to connect to it from my computer using the Ethernet cable. It sounds very like a problem other users have h...
Is the mode of the 7800 actually set for AP mode or router mode?
If you have the 7800 in AP mode, the the 7800 should be connected to the main host router via one of it's LAN ports in back to one of the LAN ports on the main host router. Do not use the WAN or Internet Port on the 7800. When in AP mode and using LAN to LAN connections to the main host router, log in to the main host routers web page and look at the connnected clients table to see what IP address the 7800 is getting from the main host router. Use this IP address to access the 7800s web page.

It was originally set it AP mode which I have now changed to router mode. From the post above it sounds like I need to be in AP mode instead? I thought that was what had caused rthe problem. Getting more puzzled by the minute.
It sounds from your answer like I need to have the router connected to the modem (what I am calling the modem is what I assume you mean by "main host router" - it's the thing on the edge of the network given to me by my ISP)
Sorted! It was because I was using the Internet port not a LAN port. Now connecting fine.
Glad you got it working and it was just moving the cable to the LAN port. Enjoy. :smileywink:

Cool, although look at the Furry's response. You are "double routing" which is fine and probably not introducing much latency (a little), but it's not the most efficient. It depends on how much performance you want to squeeze out of it and how much you want to control your network. If this sorts you and it all works, then you should be ok.
If there using AP mode and using the LAN to LAN method, theres not double routering or double NAT condition here. Single NAT remains on the modem/router. Using my 1st mentioned menthod with the WAN port and DMZ on the modem/router, ya, there is a double NAT condition here.
The BT Hub 5 I believe is a modem/router combo. We always recommend the these modems be bridged if possible however in some cases, they can not. You'll need to check with the ISP about this. If it can be, then you can run the 7800 in router mode.
If the ISP modem can't be bridged, then you'll need to either use the 7800 in router mode and you can connect it using the WAN port on the 7800 to the LAN port on the modem/router, then use the DMZ on the modem/router and input the IP address that the 7800 gets on it's WAN port and put this in the modems DMZ. You have a two router configuration which will work.
2nd option, if your going to use the modem/router as the main host router or can't be bridged, use the 7800 in AP mode and connect the 7800 using its LAN port, Not the WAN port to the LAN port of the modem/router. Then turn OFF all wireless radios on the modem/router, if any, and use the 7800 as your wireless access point while using the modem/ router as the main router. I recommend trying this configuration for now.
