Title: CenturyLink DSL
Post by: PG on March 07, 2012, 10:59:40 AM
Having trouble getting my DIR-655 to connect to the internet through the ZyXEL PK5000Z they sent me. I can connect to the Internet when connecting a computer directly to the ZyXEL, but my network is behind the 655 and I cannot get that and the ZyXEL to play nice. Any suggestions or advice are appreciated.

DIR-655 HW A3 FW 1.21
PPPoE connection

*Update* - After searching the FAQ, I discovered D-Links recommendation to bridge the DSL Modem / D-Link Router. Once accomplished, the two devices play nice with each other.

Thats its man.
Also make sure the Always On is selected for PPPoE setting on the 655.

Enjoy.

Thanks. Any reason? I thought the FAQ said to keep it on demand...

Seen it where sometimes the router and modem won't reconnect if ON Demand is selected. So ALWAYS ON is preferred.

UPDATE
Service dropped out 2x this week for no apparent reason. CL says their side has no issues. No system or software changes on my end since I got the service up 2 weeks ago. CL currently has me bypassing the D655 and using just their modem/router (identified above) in order to monitor if the pppoe usr and pswd is dropping off the server or their modem.

Is it worth upgrading D655 FW? Could that be an issue? Any help appreciated.

I would look at the logs and see if there are any entries during the time frame the router seems to loose connection.

Review the FW update sticky in this forum before updating FW. Its worth a try. If it happens again, I might presume there is an issue upstream from the router.

No clues in the logs. Service has not been interrupted in the last few days bypassing the D655 and using just their router/modem (zyxel). I'm thinking the best path is to upgrade to FW 1.35NA since I do not have the RevB model.

I have read the upgrade faq and am wondering if there is anything else I should be aware of or any suggestions before I start the upgrade.

Follow the FW update sticky. Since your coming from 1.21NA to 1.35NA, after you do the final factory reset, it would be highly recommended to configure the router from scratch and not load any saved configuration file. If you need any settings from whats currently loaded now, take screen captures of each option that you have currnetly set up and save them or print them off. Let us know how it goes.

 No joy.

It does seem to be choking on the WAN speed check - here is the relevant text:

[INFO] Tue Mar 27 17:49:49 2012 Estimating speed of WAN interface


Also got this after upgrading:

[INFO] Tue Mar 27 17:51:50 2012 Unable to find DNS record for firmware upgrade server wrpd.dlink.com.tw

Not sure what my next move is, any help is appreciated.

Swap cables between the modem and router. Try a new cat 5e if you can.
How old is the ISP modem?

What ISP Speed UP do you pay for?
Try turning off the Automatic UPLink and set a manual 2048 or 4096 speed.
Select type as DSL.

Any chance you can take this router to a different location with a different ISP like a friends house or family house to test?

Turn OFF the check for new FW.

Finally found some time to try these suggestions. Still no luck.

I didn't think the cable was the problem because I could connect to the internet with the zyxel in bridge mode and a laptop configured for pppoe using the same cable that connects the zyxel to the dlink. I swapped it out with a known good cable anyway and still no connection.

The ISP modem is supposed to be brand new. In fact, during one of my conversations, I heard them remark that "it's date was this past March 3rd."

I'm paying for 12mbps.

I assume these suggested changes are found under QOS? I made the changes there with no luck.

Still looking for another location I can take the dlink to...

I get this a lot when rebooting the dlink:

Please wait...

The gateway is currently measuring your network connection.
Accessing this web page might have an effect on the measurement.
This page will refresh shortly.

Here are the logs, hopefully they'll help. Please disregard the timestamp from March as that was before I re-set the time on the dlink. Comments after:

Each break in the above code indicates a restart by me after making changes. Interestingly, I did get a momentary connection. It started before the UDP packets attack but as you can see, it only lasted 22 seconds.

The UDP packets were from, top to bottom: China, Macedonia, France, Algeria, Latvia, Spain, Taiwan, and Thailand.

CenturyLink has, on a couple of occasions, told me to make sure the VPI is set to 0 and the VCI to 32 - I have no idea where to find these.

Thanks again for your help.

Try changing the MTU from 1500 to 1496 or 92 found under Setup/Internet/Manual.

There is no VPI settings in the router for DSL connections, if there is, it would be under Setup/Internet/Manual/Connection Type/PPPoE however I don't think there are.

Your NAT settings are restricted or independent under Firewall? Ensure your keeping SPI ON always. Since your getting some traffic from over seas, your router is doing his job by blocking it.
Title: Re: CenturyLink DSL
Post by: PG on April 05, 2012, 01:56:47 PM
I asked CL what their MTU settings should be, and the router default was already at their recommended rate of 1492.

Yeah, I suspected there was nothing there for VPI / VCI. I've looked everywhere.

NAT settings are:
UDP Endpoint Filtering: Address Restricted
TCP Endpoint Filtering: Port and Address Restricted
SPI is simply a checkbox to enable it.
Title: Re: CenturyLink DSL
Post by: FurryNutz on April 05, 2012, 02:32:23 PM
Try Endpoint Independent for those TCP and UDP.
Title: Re: CenturyLink DSL
Post by: PG on April 12, 2012, 01:07:01 PM
Nope, that didn't work either. And even if it did, I'm not sure I'd be comfortable lowering the security to that level.

I'm ready to give up. As much as I would like my network to stand behind my own router, I don't see what else can be done other than to just use their router.
Title: Re: CenturyLink DSL
Post by: FurryNutz on April 12, 2012, 01:12:41 PM
Your not lowering any security, just how NAT is handled.

Maybe someone can review your router settings with you using teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.

Other than this, you might be stuck with there modem and router. IF this is the case then I might try using a external network switch on the back end of the modem and maybe add on a DAP model AP wireless device for wifi instead of using a external router like the 655.

We're getting into new territory for me - would you mind taking the time to explain why you recommend this setup? Or maybe a link? I'll understand if you don't; you've already given much of your time and I appreciate your effort.
Title: Re: CenturyLink DSL
Post by: FurryNutz on April 13, 2012, 01:54:58 PM
Sure.
Reason for my suggestion, it seems that some ISP Modems have built in router. Some can be disabled or bridged and effectively turning that function off with in the modem and giving that duty to the external router, i.e. DIR-655. In some cases however, we've seen that in most recent ISP Modems, they are making it hard to let the modem and external router interact with each other. One reason is that ISP are providing more than just Internet service, there providing voice and video services as well, as this is all being handled by the ISP Modem. Thus bridging is not an option on some of these modems. This can make working with external routers a bit more difficult as external routers are designed to handle internet services, DHCP Cable and DSL PPPoE and other protocols. Having 2 routers on the same line causes Double NAT (http://www.practicallynetworked.com/networking/fixing_double_nat.htm) issues among other problems seen when in this configuration. Sometimes most ISP modem include was called DMZ. This option is supposed to un-filter and pass any and all data traffic from the Internet side of the modem or router to the private LAN side with out any interference. In most cases this works and helps with connecting external routers should the ISP modem not allow any bridging. I've seen in some DSL modems as of last there has a newer version of DMZ (Plus) which is supposed to work well, however, some people are having some problems with it and working with various devices. So it seems were hitting another bump in the road with modems and external routers.

The reason for mentioning the DAP-1525 for example (http://amplifi.dlink.com/products/DAP-1525), model APs and and switch in your case, it seems to be that the ISP modem is going all the modem and routing and networking functions. It's possible in come cases that customers can buy there own modem hardware to use with external routers as well. Some ISP don't allow this. There are pros and cons to all this. Anyways, if the ISP modem is going to handle all the modem, router and networking functions, why have another router trying to do the same thing. Lets take the external router off the line and replace with just a AP and a switch. The AP will provide you with 2.4 and or 5Ghz Wifi and the switch will provide you with additional wired connections should the ISP modem be limted to 4 ports or a few in back. Doing this will eliminate the extra external router condition with the ISP modem and router thats already doing the job.

This suggestion works great and I thank you for posting this info ..  I too have centurylink with their junk zyxel pk5000Z .. the zyxel did not do port forwarding correctly, setting up reserved dhcp wouldnt work, and about half a dozen other things ..

Followed both the Century Link and Zyxel self helps at turning off wireless and then putting it in transparent bridge mode.  All you need from that hunk of junk is the ppoe user name and ppoe password ... plug those into the DIR-655 and changed settings recommended on the first page of this post .. smacked the connect button PURRFECT ..   Thanks !

VPI / VCI  those settings are in the zyxel

*Update* - After searching the FAQ, I discovered D-Links recommendation to bridge the DSL Modem / D-Link Router. Once accomplished, the two devices play nice with each other.
I have a Zyxel PK5001Z that works OK when I connect to it directly. At home I have my DIR-825 (2.02NA) connected to my Bell Dsl modem no problem.

Now, (at this different location) with my Dlink connected to the Century Link Zyxel (patch cable from internet port on the router to one of the 4 ethernet ports on the modem), it displays that it has internet connectivity and my PC says it's connected to the internet, but my browsers won't display any webpages.

What exactly did you do to 'bridge' the modems?
