WRVS4400N PPPoE issues

Hello,

Few days ago i bought WRVS4400N and i tried to connect it to my ISP which is working only on PPPoE connection. Unfortunately we wasn't able to make it work. Please see below the log of the router when i try to connect via PPPoE:

I forgot to add that the router is v2 and i recently updated the firmware to the latest 2.0.0.7

Re: WRVS4400N PPPoE issues

Noone have any ideas?

Re: WRVS4400N PPPoE issues

This may be a too obvious of a question but I have to ask. Is your modem set to "Bridge" mode? From the log it looks like it may not be.

Check and let us know. If you are not sure a simple test would be to plug the router to the modem and set it to DHCP, and take a look at the address it receives. You may be surprised to find that you actually got a public IP; however, it is most likely you will get a "192.168.x.x" address.

I have been noticing that more and more DSL providers are providing modems that will automatically bridge themselfs when a router is detected.

New Member

Re: WRVS4400N PPPoE issues

Hello,

Thank you for your reply. Unfortunately in my case i am not using a modem, it is just a lan cable comming from my ISP directly connected to my router.

New Member

Re: WRVS4400N PPPoE issues

Is the MTU size for your PPPoE connection set to auto?  I would set the MTU to manual and set the size to 1492.

New Member

Re: WRVS4400N PPPoE issues

Hello,

The MTU size was auto at the beginning then i tried with change it but without any success

New Member

Re: WRVS4400N PPPoE issues

Is it possible this is an ADSL connection instead of a DSL connection?

New Member

Re: WRVS4400N PPPoE issues

No, this is a pure lan connection, there is no client modem. I am not sure what type of device the ISP have on the other side. Thanks!

New Member

Re: WRVS4400N PPPoE issues

If you bypass the router and set up a PPPoE connection from your PC, using the user name and password given by your ISP, can you access the internet?

New Member

Re: WRVS4400N PPPoE issues

Yes without any problems

New Member

Re: WRVS4400N PPPoE issues

vl.angelov,

     I am sorry for all the questions, but what is the ISP company you are using?  Thanks.

New Member

Re: WRVS4400N PPPoE issues

Hello,

It is one of the biggest ISP in Bulgaria, which basically offer LAN and Optic internet connection. In my case it is LAN connection thru ftp cable.

New Member

Re: WRVS4400N PPPoE issues

It looks like the WRVS4400N is not understanding the PADO being sent by your ISP. Please ask your ISP what RFC they use for their PPPoE connection. I will do some research on my end and try to have some answers to a few questions I have about our routers. I will be awaiting your response.

Bill

By the way, what username are you using to connect? You can Private Message it to me if you don't want to post it.

New Member

Re: WRVS4400N PPPoE issues

Hello,

Thank you for your suggestion. I already contacted my ISP and waiting for their answer. Regarding the username its quite standard but it have 1 at the end. Could it be the problem that we have a digit in the username?

New Member

Re: WRVS4400N PPPoE issues

I was merely asking for the username for debugging purposes. I do not think a digit in the u/n will be a problem.

New Member

Re: WRVS4400N PPPoE issues

As per my ISP the RFC used by this PPPOE protocol is 2516

New Member

Re: WRVS4400N PPPoE issues

vl.angelow,

     We are going to try to replicate your situation in our lab and see if we get the same results.  We will keep you posted and thank you for your patience.

Re: WRVS4400N PPPoE issues

Try cloning the mac address of your pc that will connect into the wan interface of the router. I see you are getting the PADOs but after that is when it is failing. I think the mac address you are sending with could be the problem.

Bill

New Member

Re: WRVS4400N PPPoE issues

Thank you for the suggestion. I will try it, but i am not quite sure that this will solve the problem, as my ISP is not locking the PPPOE by mac address.

New Member

Re: WRVS4400N PPPoE issues

Unfortunately this mac address cloning didn't help to solve the issue. Do you think the problem can be also because of the service name that is assigned by default of the router? Also i noticed that i don't have an option to either use or not a service name in the PPPOE settings? Is there any option to access it? Thanks!

Re: WRVS4400N PPPoE issues

You are using the equivilent to Verizon's FIOS fiber internet connection. I have ran into this problem in the past with the WRVS4400N. The connection is very different and when we set the router to PPPoE the router begins to negotiate the link protocols; pvc, for example. The thing is, I do not beleive this connection to be true PPPoE; because of this, I feel we end up with a conflict. We need authentication but, we do not need to negotiate PPPoE, so our real solution is to set a static IP address on the router and see if we can get out. This would be my suggestion:

Not sure if this has already been asked, but have you already tried to set the router to DHCP; if so, were you able to get an IP address? It doesn't matter if it was private or public, just post if you did receive one.

The other thing to try is, since you are able to get to the internet from your computer, write down the IP address, submask and gateway you received and we will put that information as a static entry on the WRVS. I know this is very reaching, but just trying to figure out if the router is the problem or if the problem is with the configuration.

Please keep us posted.

Re: WRVS4400N PPPoE issues

Hello,

By default the router is set on DHCP, it seems that there is a dhcp server in the same LAN network but its not from the ISP because i already asked them about it. I didn't try yet to put static IP configuration but on my computer i can see when typing command ipconfig that the IP of the PPPOE connection and the Gateway are the same. The LAN interface itself again is getting private ip address from a dhcp run in the same network.

Cisco Employee

Re: WRVS4400N PPPoE issues

Is this a business or a home network? I might have incorectly assumed we were talking about a residential line.

Do you manage a DHCP server? Also, I am understanding that when you set your router to DHCP you are in fact getting an IP address; albeit a private address. Is that correct?

If that is correct, are you able to get to the internet?

If you do receive an address on the router, run these commands:

ping

ping 4.2.2.2

ping google.com

tracert google.com  (if from a Mac use; "traceroute")

Paste the results on your next post.

New Member

Re: WRVS4400N PPPoE issues

This is a home network. The WAN of the router is set on dhcp and its getting private IP address from the network but not from the ISP. The Lan of the router is set on dhcp also and its working fine. The essential problem is that the router is unable to connect to the ISP via PPPOE connection. Again i would like to know if there is an option to set/remove Service name from this router model as i cannot find such an option in the PPPOE menu where the other Linksys router models have.

Cisco Employee

Re: WRVS4400N PPPoE issues

I will need to check, or may be an engineer will step in and answer that question. I do not think we have that option on the WRVS.

OK, great the fact that you are getting an IP address (regardless from who) is a good start. Did you receive an IP of 192.168.1.X with a GW of 192.168.1.254?

The address that you are getting is very important, as we may be closer to getting on the internet than we think.

I am heading to bed now... very late! but if you are getting an address like I stated, change the dafult LAN of the WRVS to something like 172.16.10.1 and then see if you are able to get out.

also posting the results of those commands can give us a better idea on how we are connected.

New Member

Re: WRVS4400N PPPoE issues

Yes it is a private address but like i said before this IP address configuration is comming from unknown dhcp server on the same network, the ISP by default is not giving any IP address on dhcp, it's just a PPPOE connection with username/password. Regarding the service name, if its not included in the web interface maybe there is an option to access/change it via CLI connection? Thanks!

New Member

Re: WRVS4400N PPPoE issues

I checked everything, when i am connected to the PPPOE from my computer the lan card is getting:

IP Address. . . . . . . . . . . . : 192.168.0.100
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . . . . : 192.168.0.1
DNS Servers . . . . . . . . . . . : 192.168.0.1

Again thise IP configuration comes from an unknow device in the network - D-LINK DI 254 and its not related at all with my ISP

Also i changed the LAN configuration on my router to be in 172.16.1.x network but i still can't connect via PPPOE

If you have any other suggestions will be really appriciated!! Thanks!

Ok, to clarify what I was saying earlier; I would not disaggree with you in saying that the IP address you are receiving may not be comming from the ISP. The thing is, since the WAN is receiving this address it may mean that we are trying to authenticate PPPoE through this unknown device; this will cause a problem.

Now when you get this address are you able to get out? Can you post the results of those commands I posted earlier when you have the above address on the WAN?

This is the problem:

WRVS  <==> WAN <==> UNK Dev <==> LAN <==> Modem? <==> Internet

That device needs to be found, and taken out of the path to the Fiber (PPPoE) connection. Please run; ping, tracert against google or a public domain and let us know the results. As long as that unknown device is in the way we will not be able to authenticate PPPoE.
