Setup:
Netgear DG834PN in modem-only mode, connecting LAN - WAN to Asus RT-N66u router via PPPoE.

edit: I think it's something to do with the fact that the modem is connected through the router's WAN port?

If so, change the Netgear management IP address to something in a different subnet, such as as 192.168.100.1

Quote from: shure Netgear DG834PN in modem-only mode, connecting LAN - WAN to Asus RT-N66u router via PPPoE.
That mode almost certainly switches the router element input/output so that the router function is totally disconnected. Whilst a second 192.168 segment could be addressed on the ASUS WAN port, all the packets would just be passed to the first router beyond the modem (and then dropped).
The easy way to get the stats is to not use bridge mode - though that introduces it's own problems, such as two firewalls The ASUS will route packets that are not for the local network to the WAN interface.

@PeeGee - I understand what you mean. Is there really no way to monitor modem traffic with a separate modem and router, though? Seems like a harsh trade-off!

I have the above working at another site.
On a fibre connection, an unlocked Openreach Huawei HG612 modem can be accessed by connecting the LAN2 port from the HG612 to any spare LAN port on the attached router. But from what I've read on Kitz forum, sadly I don't think anyone has got this combo working when the HG612 is specifically configured as an ADSL bridge modem. ie. it only seems to work in fibre (VDSL) mode from what I've googled.

This is, unfortunately, an area of confusion, where the term "modem" is incorrectly used for a modem-router(+) combined unit (another example being millibits per second (mbps) used for megabits per second (Mbps) or even megabytes per second (MBps) )
In the case of the DD-WRT firmware, it seems to leave the router active and connected in bridge mode, though it is not clear if it allows "private address" messages (eg 192.168 series) through to the modem or drops them (which will happen at the next "router"). The need for "strong passwords" suggests the former.

One of the reasons I wanted to check was that I'm currently getting 6.74 Mbps average, while my IP Profile is rated as 7.15 on an 8Mbps line (hey, when you're on ADSL1 every little helps!). Is that a reasonable speed to get and is there anything I can do to try and tweak things?
Thanks in advance

Quote the Netgear already uses a different range - 192.168.0.1 vs 192.168.1.1 - so can't change anything there
I really dont know.. and may be wrong.. what subnet mask are you using.
Have you tried say 192.168.1.1 and 192.168.1.254
Someone better at IPaddressing may be better to answer than me, but just throwing in a possible cause.

It looks like I may have to put the Asus back in the DMZ of the Netgear and sacrifice remote login at this rate, which is a bummer as I was really hoping to use it (I work away from home a lot).

Quote from: shure How are you supposed to diagnose if there is a fault or e.g noise on the line, or even disconnections (or whether your line has interleaving on etc)?
You'll have to configure a static IP on your PC (192.168.0.2/255.255.255.0), disconnect your Asus from port 1 of the Netgear and plug your PC in instead. Once you are done grabbing diagnostic data, plug your Asus back in and set your PC back as it was.
The problem is down to the fact that your Asus router is using PPPoE and getting a WAN IP address through the Netgear 'modem'. As a result, there isn't IP connectivity to the modem.
[ADDS] Thinking more, try configuring your PC as above and trying a LAN port other than port 1. If you can access the Netgear GUI then set its IP address to something outside the Asus DHCP range eg 192.168.1.253 and then plug port 2 of the Netgear to a LAN port on the Asus.

Thanks, but as the Plusnet login is being handled by the Asus router now I don't understand how that would work? Wouldn't I have to change the Netgear to modem+router mode anyway to do that (and change from LLC to VC etc)? Or have I totally misunderstood?

fwiw, if you are referring to remote login to the Asus, this in theory is possible. On your Netgear, you need to look at setting up port forwarding rule to the IP address assigned to the WAN port of the Asus.
I would suggest try setting it up without putting Asus into DMZ first. Once you have it working, put the Asus back into DMZ and see if remote access is still working.
