Title: DIR-868L WAN port with Gb Fiber ISP
Post by: Austinbike on November 23, 2014, 05:52:39 AM
I have a fiber internet connection to my ISP.  While it is capable of gigabit speeds, I am provisioned at 50Mb/s (with my usage patterns it made no sense to pay the extra for Gb, the performance was no different...)

Originally when they set it up we ran into an issue with the ONT, it was provisioned to only see gigabit connections, so I could plug a notebook in to the ethernet jack on the wall and get an IP, but if I plugged in any router, it would not connect.  They reprovisioned the ONT to auto from Gb only and now any router would get an IP.  It works fine with any computer, or my DIR-655; I am actually getting ~75Mb/s on my 50Mb/s account.  All is good.

EXCEPT that if I plug in the DIR-868L I get only 7-15Mb/s if I set the WAN port to "Auto".  If I try anything from 10Mb through 1000Mb it does not even work (can't get an IP.)  I have tried every firmware rev from 1.04 through 1.09 and none of them has any impact.  Literally nothing changes on the network, I just swap the DIR-655 with the DIR-868L and the speed immediately drops.  I have pinned it down to the WAN connection between the 868L and the ONT, but beyond that I am puzzled.

The reason I care is that inside the network, downloads from my NAS are ~40Mb/s on the DIR-655 and ~80Mb/s on the DIR-868L. 

So literally i have one router that is fast on the outside, slow on the inside and one router that is slow on the outside and fast on the inside. 

Any thoughts on what is going on here? 

I can go set a static IP with a 100Mb or 1000Mb speed and see if that works and if the speed is right, but my ISP uses DHCP and I do not want to set a static IP as I may lose my lease and have to go back and reset periodically.

Hi,
If cloning the mac id does not get it done, as a work around, you might consider bridging your DIR-655, and then connecting your 868L and seeing if that works for you. (Apparently this is not supported any longer but can be done.)
http://forums.dlink.com/index.php?topic=40856.0 (http://forums.dlink.com/index.php?topic=40856.0)
I would also consider looking for a forum from your ISP and seeing if you can glean any information or help on that front.  As a last resort, you might try calling Dlink's support line for whatever country you are in.

Cloning the MAC did not work.

Setting a static IP for the 868 did not change anything.

I could try putting the 655 in bridge mode in the next few days and see what happens.  Since that time I put the NAS and my main workstation on the same switch (instead of tiering the switches) and that has helped on the 655's internal network speeds.  Since I have A and B rev 655's I may swap them around as well.

Ultimately I have a pretty complicated network setup and too many moving pieces is not making me a happy boy.  I just want stuff to work. 

If I can get the 868 running in bridge mode that doesn't really help me (other than troubleshooting) because I am trying to reduce devices....

I would test the 868L out at a different location just as a test to see if you notice the same problem follow. If you have a neighbor, friend or family that you can take the router too and see if the problem follows. If it does, then it needs to be RMAd. If not, then you'll know there is a configuration issue at your location.

This has acted the same with every firmware, I started with 1.08, upgraded to 1.09 and then downgraded to 1.04 and 1.07 with exactly the same behavior.

Going to try the bridge mode on the DIR-655 if I can figure out how to do that.

You may want to take it to a different location. If you have a neighbor, friend or family that you can take the router too and rune a quick test. If the problem follows, then you'll know and it needs to be RMAd. If it doesn't, maybe a issue between the router and the ISP modem.

It is not a modem, it is an ONT, they don't have modems for fiber.

I will try to take it to another location.

If I stick a plain ethernet switch in front of the router, between the router and the ONT, will that setup work for testing purposes?  I've never tried to put a dumbe switch in front of a WAN port before.

Looks like an interoperabilty problem (http://en.wikipedia.org/wiki/Autonegotiation#Interoperability_problems) between the ONT and your DIR-868L WAN port affecting auto negotiation (http://www.ethermanage.com/ethernet/pdf/dell-auto-neg.pdf) and resulting in a duplex mismatch (http://en.wikipedia.org/wiki/Duplex_mismatch) in the worst case. If so, you should see a high rate of dropped packets, collisions and/or errors in the WAN STATISTICS section in the STATUS | STATISTICS web page of your DIR-868L's GUI. Can you check this?

If "bridging your DIR-655" just means using two LAN switchports of the DIR-655 one connecting to the ONT and the other one connecting to the WAN port of your DIR-868L (this way reducing your DIR-655 to operate as a switch only), both suggestions are equivalent and might help if the assumed underlying interoperabiltiy problem can be circumvented this way (in that the interswitched switch understands both IEEE 802.3u "dialects" spoken by the ONT and your DIR-868L's WAN port).

Hi all,

Did this post ever get to a solution?

I have exactly the same situation here: I "upgraded" from a DIR-655 to a DIR-868l. This vastly improved the performance inside my house, at the cost of my upload speed.

I also have a fiber connection to my ISP. Speed test with my laptop connected straight to the fiber "modem" (Optical Netwerk Terminal) reports 95 Mbps download and 97 Mbps upload. My old DIR-655 managed to keep both speeds well above 80 Mbps. My DIR-868l gets about 80 Mbps in, but does not seem to be able to get more than 17.5 Mbps out.

Setup in my case:

I already contacted D-Link support using the Self Service Portal. They suggested to set the WAN connection speed to 100Mbps manually. To me this was a questionable suggestion, for how can I get an 80 Mbps download speed if the Ethernet connection is less than 100Mbps? My ONT does not support Gigabit ethernet, so it makes no sense to do anything else than 100Mbps.
Now, the status of my case is set to "waiting for the customer", but I have no idea what kind of information they are waiting for.

I wonder if anyone has reached a WAN upload speed of more than 20 Mbps through a DIR-868l? Specifications always mention the max. connection speed of a WAN port, but never mention something about the max throughput in both directions.
Can anyone confirm that the DIR-868 should be able to upload 100 Mbps to WAN?

 
Title: Re: DIR-868L WAN port with Gb Fiber ISP
Post by: FrancZ on March 21, 2015, 03:45:53 AM
After my previous post, I planned to connect my old DIR-655 inbetween my ONT and my DIR-868l. The idea was that the DIR-655 would take care of negotiating connection speed with the Packetfront, and the DIR-868l would take care of LAN traffic.

In the process of setting up the DIR-655 in a bridge-like function, I noticed a setting in the QOS section that was related to the uplink speed.

This reminded me that I did change the QOS settings in my new router as well (giving priority to a PlayStation). So I checked.

I disabled QOS, retested for speed with Ookla and got to 91.9 Mbps down and 85.6 Mbps up.

So the limited uplink speed of the DIR-868l is caused by the use of QOS.

DIR-868l owners with ISP's that offer more than 20 Mbps uplink can only prioritize their traffic at the cost of their uplink speed.

I suppose I have to post in another topic to search for solutions for this problem?
Title: Re: DIR-868L WAN port with Gb Fiber ISP
Post by: FurryNutz on March 23, 2015, 07:19:50 AM
It would be recommended to have GB connection speeds on the ONT if possible. If it doesn't support 1000Mb between the ONT and the router, then you might ask for an ONT upgrade. 1000Mb connection rates is preferred on the WAN side. If the 868L only supports 20Mb uplink speeds in the QoS settings then this will be the max that it can handle. Most home users may not have these kinds of uplink speeds for these home class routers thus D-Link may set this limitation due to this general home usage in speeds. The DIR-655 has a limit of 2Mb I believe from the old days. I recently up got upgraded to 3Mb here. So there are some routers that I have that exhibit this uplink issue since they are limited at the 2Mb cap. Disabling TS and QoS resolves this.

If your using this in a business environment then this may not be a good choice in routers as you may need a business class router for handling higher ISP speeds. Home class routers are generally for the average home user with speeds usually lower than 20Mb.

Yes you can disable TS and QoS on the router and then the speeds will be correct. Theres been debate on weather QoS is really needed at those higher uplink speeds. Thus maybe it's not really needed.  ???

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. As them about your speeds and weather this model router is best suited for you. If not, ask them which model router is more suited for your needs. We find that phone contact has better immediate results over using email.
Let us know how it goes please.

Update on my previous post: D-Link support suggest not to use QOS.

So I wonder... is it strange to want to use QOS with uplink speeds over 20Mbps?

One of my hobbies is to make video-registrations of my son's soccer matches and share these files (up to 10GB) over a cloud drive share. It takes about 20 minutes to upload (100 Mbps symmetric connection to the ISP).
During upload, I want to prioritize the network traffic of my son's Playstation. Isn't that what QOS is meant for?
Is the use of QOS somehow dependent on the uplink speed of the connection, otherwise than that it will take a little longer before game lagging can occur?

In other words: am I expecting something that makes no sense?

Theres been debate on weather or not QoS is needed on Uplinks faster than 20Mb. I presume D-Link gave some thought to this and giving that the average home user, at least here in the USA, doesn't have uplinks faster than 20Mb, may have only allowed for 20Mb and that was it. Any thing more then that may not need any QoS as the Uplink would be fast enough to handle several connections with out problems. Most game consoles while gaming don't take up 20Mb at a time, I've only seen 5Mb bandwidth on my 360 max while gaming and thats on the downlink however I have 50/3 here so QoS for me is beneficial. I don't know for sure what PS does or what it needs. PCs are entirely different and generally can take up more bandwidth.

If you have 100Mb uplink then QoS maybe of no use to you as 100Mb should be great for uplinks.

If you used QoS, then you could set up a rule for the PS and set a priority at 128 or maybe 200. Set up a higher Priority for your PC that does the uploads to 50.
You can follow an example here:
 DIR-645/835/868L/865L/826L Gaming and QoS for XBL (http://forums.dlink.com/index.php?topic=44869.0)

The uplink will be limited to the 20Mb max though...

I don't know if D-Link will be making changes to the QoS engine. Especially that this model router, as it's development should be closing as it's been about two years. Only changes would be to address any security problems in FW. The newer generation routers like the 880L and 890L with the new UI, http://forums.dlink.com/index.php?topic=59563.0 (http://forums.dlink.com/index.php?topic=59563.0) those may be more supporting of higher uplinks over 20Mb. However, the new UI is less granular and less advanced and more tuned to simplicity and automatic detecting features.

DLink seems to be keeping the old UI on one of there new follow on routers:

Thanks for your answer.

When combining gaming with bulky uploads, I assume it's not the amount of data that the Playstation has to upload to some server, but any type of delay/latency in the connection that could cause problems.
When prioritizing data from a game console over bulky uploads, I would expect that the small amount of gaming data would be fit somewhere inbetween the data packets with the smallest possible delay. I expect this to be useful at any uplink speed, as soon as the actual uplink speed approaches the capacity of the connection. It's not that difficult to bring a 100Mbps uplink to its limits (FTP with another computer using the same ISP).

I have disabled QOS, since then the DIR-868L had no problems at all. I now apply Time Division Multiplexing (uploading at night or during school hours) to avoid gaming lag. As this is not for professional or even everyday use, it works for me.

Thanks again for reacting.

Yes, depending on your configurations and applications and what you have going on, I presume it would be fairly easy to max out a 100Mb connection UP or Down. We see this a lot with torrenting users complaining about lag or slow speeds. Well, Torrents are notorious for being bandwidth hogs and users fail to realized that router have a certain limit of actual connections and any application can use not just one or a few, however can use several hundred. Torrent users are notorious for setting the DLs and getting as many has they can with out understanding that they will eventually max out bandwidth and cause slow performance. We can only suggest that users set limits on the Torrent/FTP download programs to help manage bandwidth.

Glad its working for you.

Hello all!

I've just upgraded to a 1000Mbps internet, but through the router my maximum download speed is 330Mbps. Of course the WAN speed is set to 1000Mbit. Another interesting thing is the ping is pretty high, around 30-40ms, compared to an AC wifi device that shows 5ms. I think there might be a setting that cause this limit for LAN ports.

I've also checked all LAN ports with different CAT6 cables, but no changes.

Directily connected the computer is fine, 930Mbps download speed.

Could you please help me find out what cause this issue?

I've tried 1.09 and 1.10 FW for my A1 rev device, with no luck.

Hi!

I'm still in connection with the support, they recomended to install 1.07 and now it allows around 400Mbps speed with 20-25ms ping.

Also checked LAN speed and it is way faster (almost 1gbps), so it seems that the issue is with the WAN port's speed.
