Vigor 120 v2 connection issue with Asus RT-N66U

Hi all,

Having Issues getting my Asus to connect to the Vigor 120 ADSL2 modem.

So far the Vigor is picking up Internet connection as the LED is on, when I log into the Vigor I see online status as connected but it has a static IP...(not sure if that is how it suppose to be)..because when I login into the Asus and select PPPoE and add ISP details it doesn't connect...

Can some please advise (not advanced enough in networking clearly!)

Thanks in advance.

The vigor 120 should only be authenticated and fully connected once the PPPoE session is initiated.

Sounds almost like it is not running in bridge mode

Ok I'm in the vigor settings can you break down how I should be bridging the vigor?

Assuming I need to select MPoA
What Encapsulation should I set?
VPI?
VCI?
Modulation?

WAN connection Detection
mode: ARP/Ping Detect/Always on?

Also should I have DHCP enabled in the vigor and disabled in Asus?

The Vigor should be in bridge mode, with its DHCP disabled and enabled in the ASUS. See Draytek help page.

Thanks for the link, just following the steps but noticed I don't have multi pvc option in my vigor 120. I'm sure there were more options! Not sure where they have gone. Any advice?

Never had any issue with DHCP being on both in Vigor and router, as long as the IP range is different and mask is 255.255.255.0 so that DHCP requests from router's LAN don't get through to Vigor. Vigor actually works in DSL modem-only mode, not bridge mode.
@OP: I can try to download my config and attach it here because the settings you're quoting sound wrong. Also, out of the box, Vigor does not handle PPPoA/E so you have to set it in the router, but in fact there are hidden settings on its page which enable you to get Vigor do the auth. Perhaps this kind of setup would be easier for you, unless you want your ASUS to get IP direct from the ISP.

You shouldn't really need to touch the Vigor's settings as it comes configured in bridge mode by default. Easy solution is to do a factory reset on the vigor either via hardware button or through the web GUI and that should do the trick.

They are both the same

I'm sure the vigor was set to bridge mode but tried everything I.e using DHCP on/off the vigor and Asus, different modulations and it's just not working..

Would be great if you could send ur setting for the vigor! I'm having no luck at all..

Thanks

Also is it best to connect vigor to LAN to PC first make all the necessary configurations. Then do I connect the vigor to Asus via WAN port? and Asus Lan to PC and go through Asus setup? Sorry just making sure I'm following correct steps.

As I mentioned earlier, you need to factory reset the Vigor 120 which will put it in bridge mode by default. You do NOT need to manually change any settings unless your ISP uses non standard PPPoA settings. I vaguely remember O2 users had to change something on the Vigor 120 but for the other ISPs the default settings worked fine. BtW which ISP are you with?

If still no luck then connect a PC to the Vigor using an ethernet cable and try setting up a PPPoE internet connection on your PC. If you are able to get online via your pc then there's nothing wrong with the Vigor, the issue is with your Asus router. I would check the settings on the Asus, primarily making sure 'connection type' is PPPoE. As a last resort I would factory reset the Asus and start from scratch.

What configurations? The Vigor 120 is just a dumb modem and is designed to work out of the box...

I wouldn't say that, but certainly straight out of the box that is in effect how it is configured - and in the OP's scenario should be left as such.

All connection settings should be on the ASUS. With, something that hasn't been mentioned, the Vigor connecting into the ASUS blue WAN port.

In reply to a post by RobertoS:

Good point, if the OP has connected to any other port on the Asus then its not surprising he/she isn't able to get a connection.

Ok - so I've factory rest the vigor and not touched the settings.
I've then connected the Vigor to Asus via WAN port and set to PPPoE and entered ISP details (I'm with SKY). It seems to have connected to WAN so seems to be working! But no internet light on the Vigor!?

Also just a quick question now that the Asus and Vigor are connected via WAN - how do i access the Vigor I entered 192.168.2.1 but won't connect...


Side note no ADSL was being picked up in the Vigor when using SKY splitter/ADSL box to connect broadband and phone-line.

Sky can be an odd one, in the past I've found you have to clone the WAN MAC address of the Sky hub to the device that is doing the authentication

The final bit about no ADSL being picked up is confusing, if you mean the Vigor was not seeing any ADSL when the Sky hub was on the line then very normal, only one modem will work. If you mean the small microfilter worked for the Sky hub and not the Vigor that would be very odd, and suggests maybe something wrong with the vigor itself.

When you say "No internet light on the Vigor", are you getting internet on the ASUS, so able to use it? Or are you saying there is still a problem?

If the latter then see MrSaffron's post.

The 'internet ' led on the vigor will strangely not light up when successfully connected. I used to think it was a bug on the modem but apparently this is normal behaviour when connected via PPPoE. See here , under troubleshooting :

Only way to get line stats on the vigor is to disconnect cable from Asus wan port and plugging it into a PC and going to 192.168.2.1. Just a minor inconvenience on what is an excellent adsl2+ modem

As I said earlier, Vigor has got some hidden fields in the settings where you can enter your ISP username and password directly into Vigor. It is then that Internet led will start blinking.

That isn't what the OP should be messing with though. As explained by a few of us.

Guys appreciate all the support thanks again, looks like Internet is fine and will keep note of setup or even back up. The Internet light on vigor is off but if it's because of it being pppoe connection then that's fine. Looking on the Asus it's got an Internet light on.

Networking can be a right faf! But appreciate the help and knowledge all!!

Good luck, and thanks for letting us know . Come back if you have any problems in the future.
