Hey there people, my friends
, I brought this in error instead of SRP527(with modem) and faced with a restock fee of 20% I balked at the cost
So, I brought a ADSL modem Netcom
I got that working ok with vodafone but I cant seem to connect my SRP521 to the internet for some reason

Im just a home user, using my normal PC
Netcomm ADSL2 modem has rj-45 cable connected to the ethernet port on my desktop pc and in lan1 port on my modem

Cisco SRP521 rj-45 connected to the Wlan port on the SRP521 and Lan2 port on my ADSL router

I have already added my Vodafone user name and password into the Cisco SRP521

I can find the Cisco SRP521 on wifi and connect with my phone, but I cant get onto the internet by wifi.
I also cant connect to 192.168.15.1 webpage unless I connect disconnect my plug from LAN2 on my router and plug it into the ethernet connection on my PC

What am I doing wrong

Really wanting this to work as Im also set up with a 2talk account for VOIP

You need a Draytek Vigor 120 setup in PPPoA to PPPoE bridge mode.

You ideally need an ADSL2+ modem that supports Bridge Mode. If the Netcomm doesn't do this I would recommend buying a Draytek as mentioned above.

Also, there is a setting in these to prevent admin access from WiFi - under the Administration tab I think.

What model is the netcomm? The old blue NB6's have half bridge. Not sure about the newer black models.

In the internet connection set up look for 'PPP IP Extension'. When you enable that it disables NAT and DHCP. You can test to see if it is set up properly by plugging your PC directly in to the netcomm and it will get assigned a public IP -provided the PC is using DHCP for configuration.
Once that is set up get your SRP to obtain it's WAN address by DHCP and everything will be sweet.

There is no point ringing Cisco for help, you need help with the Netcomm.

The best option for what you want is the Draytek - but I'm guessing the fact you've gone and now purchased two incorrect devices that you're not going to want to go and spend more money fixing the problem.

Here is how you setup the Draytek for PPPoA to PPPoE passthrough/bridge/relay

Then in your SRP521 you configure the WAN connection to be PPPoE

Alternatively I think the Netcomm does have PPP IP Extension (aka PPPoA half bridge).

Here is a guide on connecting a modem that is similar to the Netcomm (but not exactly same) to a router via IP extension.

chevrolux: What model is the netcomm? The old blue NB6's have half bridge. Not sure about the newer black models. .

Generally not unfortunately - we used to buy a lot of the NB6's for our clients which were being put into configurations like this, but since they were discontinued we haven't managed to find a 'new Netcomm' that does have it (PPP IP Extension).
