WAN port limited to 10mbps on PPPoE

Hello,
I'm having trouble with the WAN port on my Airport Extreme. I got FTTC (fibre) coming into a VDSL2+ modem. When I connect my Mac directly to that I get roughly 70mbps download speed. But when using the Airport Extreme my connection caps at 10mbps! I have the 3rd generation, so all ports should be gigabit ethernet ports.
I saw some other posts here suggesting to set the WAN port settings in Airport Utility. I can't find those in the latest utility, so downloaded Airport Utility 5.6, changed from PPPoE to Ethernet, set the WAN speed to 1000 duplex and set it back to PPPoE. Now it refused to connect at all and claimed the cable was unplugged. Not until I went in and set Ethernet to "automatic" did it connect again via PPPoE. So it seems that my Airport Extreme refuses to use a faster ethernet connection than 10mbps when using PPPoE.
Any solution to this? There clearly is something wrong here! I contacted my ISP and they said that they have reports from other users of the Airport Extreme with the same problem.

You didn't mention this, but it could be as simple your cable from the modem to the router. If you are using a Cat5 Ethernet cable, you need to be using a Cat5e or Cat6 cable. I use Cat6 cables on my network because they are certified to run at Gigabit speeds. Cat5e is not certified but can work on a Gigabit network.
Also, when you direct connect your Mac to the AEBS you should be getting download speeds well over 100 Mbps, depending upon your system provider and what speed you're paying for. This leads me to believe it's the cable.

ISA500 tagged WAN port

Hello,
I'm currently evaluating an ISA570W firewall.
The use case is to deploy it as an entry level firewall on FTTH internet access lines.
The ISP provides a CPE that requires internet trafic to be tagged on a specific VLAN.
I was a bit suprise when, after trying this configuration, finding out that the WAN port on the ISA500 can only be put in access mode.
Which effectively makes this device unusable.
Is there another way to set one of the ethernet interface in trunk mode and put it in the WAN zone with DHCP client enabled?
Thanks,

so I digged a bit further and found a document from Cisco's knowledgebase that describes steps by steps instructions for the WAN port: http://sbkb.cisco.com/CiscoSB/Loginr.aspx?login=1&pid=2&app=search&vw=1&articleid=3719
searching for vlan tag showed me a screen that allowed the setting of a tagged vlan on the WAN port but only available for PPPoE IP address assignement.
the VLAN tag option is not available with "DHCP Client" IP address assignement.
Is this something we could see in a future firmware release?
From what I've seen tagged vlan on the WAN port is a typical configuration requirement for FTTH services here in Switzerland.
Thanks,

SA520W Optional WAN Port PPPoe fails to connect

Hello,
I am trying to connect a SA520W optional/secondary port to the Inet. ANd it always gives me this error:
pppoeMgmtDBUpdateHandler: error in executing database update handler
Component: PLATFORM
AND
pppoeMgmtTblHandler: pppoe enable failed
Component: PLATFORM
I have no idea how to resolve this.
Updated to actual firmware - same result.
Help is highly appreciated.
Ben

Hi Ben, thank you for using our forum, my name is Johnnatan I am part of the Small business Support community. I apologize for your inconvenience you are having Ben, just to make sure you are running the last firmware it is 2.2.0.7, you can download it in the link bellow.
http://software.cisco.com/download/release.html?mdfid=282414018&softwareid=282728525&release=2.1.71
I advise you to perform a factory reset, set the time correctly. Then create the PPPoE profile and apply it to the WAN port again. After you have established the connection, please continue with the rest of the configuration, if the issue continue please contact your Internet Service Provider to troubleshoot your modem or verify the necessary information.I hope you find this answer useful

Speed limitation on Time Capsule Ethernet WAN port

I have a Time Capsule 2TB model A1409 that is connected to a Motorola Cable Modem SBV5121 and only connects to it ("green light") when the Ethernet WAN port is set to 10 Mbps/Half Duplex (fastest speed - average 5 Mbps for download) or 10 Mbps/Full Duplex (slowest speed - average 3 Mbps for download). No other mode can get a connection "green light". Time capsule software is 7.6.1.
Today I connected a Cisco Linksys E2500 router to the same cable modem and download speed increased to 10 Mbps which is what I am paying for my ISP. I haven't even touched the ethernet WAN port configuration. Straight forward.
I would be grateful if someone could point out a configuration change that would allow my TC to connect as fast as this Cisco router.

It works fine in Bridge Mode with a Thomson Integrated Modem/Router. But I don't want to use this configuration since I won't be able to use the TC's Guest Network.
Just tried connecting with Cisco's ethernet cable but remained the same.
Is it possible to bridge the Thomson??
Stick a small cheapo switch between the TC and Morotola and see if that fixes it.. as I said, not all chips quite talk to each other.. even in this day and age.
And Motorola cable modems seem to have more problems than most .. this is not new to me.

AEBS: use WAN port as a LAN port ?

Hello there,
My Airport Extreme base station is connected to an Airport Express as a WDS wireless bridge (none of them distribute IP, there is a router on the network).
I have two printers hooked on the AEBS, a USB one, and an Ethernet printer on the LAN port (Apple LaserWriter). Therefore, the WAN port is not used.
I would like to connect a non-airport Mac to the network thanks to the AEBS.
Can I plug the Mac with Ethernet on the WAN port or I must purchase an Ethernet switch to plug on the LAN port and then on the Mac and printer ?
The documentation says the WAN port is for cable modem only but I don't see any hardware limitation that could allow only those device.
Thank you for your help.
PBook 12' Mac OS X (10.4.9)

Thank you Duane for those infos.
I didn't know that the difference between a WAN and a LAN port was a matter of IP adressing. Nice to know.
I will try that ASAP, if there is no more post, that means it works great.
Thanks again.

WAN port without DHCP/NAT on WRTP54G

(Sorry if this issue was already discussed - I couldn't find it using Advanced Search) I find that my new WRTP54G works fine, supporting VoIP and several PC clients via its LAN switch, providing I enable its DHCP and NAT function. This is with the DSL modem connected to the WRTP54G's WAN port, as required for the VoIP module to access the internet. However, this configuration (the factory default) results in "double NAT" when used with my DSL modem. (This situation is evident by inspecting the HTML status screens of the respective equipments.) The obvious solution would be simply to disable DHCP and NAT in the WRTP54G and let the DSL modem do the hard work. However, disabling DHCP/NAT within the WRTP54G essentially shuts down all PC client access to the internet. The symptoms resemble a situation where packets are not being properly routed between the WRTP54G's LAN switch side and its WAN port (although I don't know whether that is the precise cause or not). On my previous WRT54G router used with a PAP2T, I saw the same behavior but the workaround was simple: move the DSL modem Ethernet port connection from the WRT54G WAN port to one of its LAN switch ports. Problem solved at the expense of occupying one of the four available LAN switch ports. Such workaround is not applicable to the WRTP54G due to the previously mentioned requirement of its VoIP module. Has anyone got their WRTP54G (or for that matter, WRT54G) working properly with its WAN port as a simple (non-DHCP/NAT) router? Please note my preferred Internet Connection Type (on the WRTP54G opening Setup page) is "Obtain an IP automatically" although a solution using "Static IP" would be OK. I am looking for a portable solution (for hotel rooms etc.), so I can't set the WRTP54G to "PPPoE" as suggested in some other forums. Thanks in advance for any help!

Use the Modem connected to WAN Port of the wireless router ....
In such case you can use the DHCP of the router also & other computers using the client services can work .....
Make sure that the Ip address should not conflict between the Vonage router & Linksys router .....
I think that Vonage is giving Ip - 192.168.15.1 ...& the default Ip for Linksys router is 192.168.15.1 ..... change the Ip for any of the router or modem to 192.168.20.1 .....
Also under Linksys router once you open the setup page ....
Leave the Internet Connection type to "Obtain an Ip automatically"
Click "MAC address clone"
Click enable & click clone
Click save settings ....
See if you are able to go online or not ....

SA520W Optional WAN port problem

Hello,
I have a problem to configure the optional wan on my SA520W.
We have 2 connexions (Cable and ADSL), when I set the primary wan with the Cable there are no problems. When I set the primary wan with the ADSL there are no problems. But when I set the Cable on the primary wan, and the ADSL on the optional wan, primary wan works, but optional wan doesn't. Leds are green, link state is UP, but wan state is DOWN.

Graham,
To use both WAN ports at the same time, browse to Networking-> Optional Port-> WAN Mode. Select Load Balancing so that all traffic will be balanced between the two WAN ports. The other modes only allow a single WAN port to be connected at one time.

Performance of WAN Port

Hi there,
I ordered a 120 Mbit/s line from my provider. After some speed issues I had a online session with the service provider today. I was getting 80-90 Mbit/s ....
He advised me to take out the AirPort Extreme between the Cable Modem and my Mac Mini. First of all I did not think this will bring any improvement since the Modem is GBit Ethernet and the Mac Mini and Airport Extreme too....
As he insisted on that I took it out and what happened? Internet performance went up from 80-90 to 110-115 Mbits.
So actually there is a real cut in performance - is this a general performance limitation, like firewall/nat or whatever is making airport busy and not letting trough more than 100 Mbit .... or is the WAN port only 100Mbit?
Is there anything to tune?
Oh by the way the extreme is 2 weeks old - so it is latest model (MC)
Thanks in advance!

I've owned several routers from different manufacturers and have worked with several Internet service providers and have found that the routing process will cause, on average, a 15-20% drop in speed when compared to a straight through connection from the modem to a computer. Sometimes, its a bit more loss and sometimes a bit less.
There is no doubt that the the NAT firewall accounts for some of this loss in the routing process and the process of sharing a single connection from the modem is likely to cause some loss as well.
If had a 100 Mpbs service from the provider, I would expect on average to see speeds in the 80-85 Mbps range using an ethernet connection through the router. The Internet connection speed often varies on most providers during the day depending on the number of users on the system.
If you are talking about wireless speed, there is more speed loss here through the router due to the security encryption process.
Now, the results of other users may vary. Hopefully, they will post to give us more perspective. Based on the different routers I've used with different providers, I would say that your results are in the range that I would expect.

Setting WAN port MTU?

I mentioned in another thread that I had been having some problems with NAT on the AEBS. I think I narrowed it down to something going on between my DSL router and the AEBS.
I believe the DSL router needs to have an MTU of 1460 or fewer bytes per packet. Probably becuase it encapsulates TCP/IP before sending over its DSL ATM link.
I was able to get similar broken behavior when I replaced the AEBS with a similarly configured Linksys WRT54GS and forced the MTU to 1500 in the WRT's web managment tool.
It looks like MTU set to "auto" or 1460 or fewer bytes per packet makes the WRT54GS behave nicely with the DSL modem. Presumably, that would make the AEBS happy too... if I could find a place to set the WAN port's MTU. Anybody know how to do it?
The DSL router is about a five year old Siemens Speedsteam connected by ATM to the telco's DSLAM. Perhaps newer DSL routers do something a little smarter with packet encapsulation, fragmentation and reassembly. Not mine, by the looks of it.
Thanks,
Bill

I just waned to add, the Speedstream is taking care of the PPPOE itself. The model I have is the 5861, which is a full-blown IP router. I am getting a /27 block of IPs routed to me by my ISP.
If not the MTU size, perhaps the AEBS is setting the DF bit (Don't Fragment) bit in the IP header, so if the Speedstream needs to fragment a big packet because it is slapping on additional encapsulation for PPPOE, it has to drop the packet from the AEBS because the packet is over 1500 bytes when encapsulated.
The issue is only a problem when certain ports (say, 473 for instance) are NATted. Port 80 seems to be no problem. Unfortunately, there is more than basic HTML in this world.

Wan port question

Could someone explain to me the Ethernet wan port menu. I'm having a lot of connection problems with Airplay. It keeps dropping and coming back on.
I checked with my ISP and the signal (cable) is 100% stable so the problem has to be my AE.
If I change the settings to 10Mbps/half Duplex, it seems to work ok for a while. But Automatic is a definite no-no.
Why all those choices, especially half and full duplex and what do they mean in terms of overall performance ?
Thx

My question to you is did this always happen or just started happening with this modem & AirPort base station. What is the exact model of your AirPort? How about the modem?
This has always happened since installation 3 months ago
AE 1143 - Modem is : Motorola SB5101
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Yes
Is 8 Mbps the maximum rated download speed that your ISP is providing you for Internet service?
Speed test (http://www.speedtest.net/)
up: 8.17 - down: 1.02
Changing the WAN Ethernet port speed will do nothing to improve AirPlay's performance.
But it does ! With lower speed = less drop in feed. Or maybe it's just the fact that I change from one to another.

Won't recognize cable plugged to Ethernet WAN port

I have a new Airport Extreme. I have gone through the setup process and it flashes amber. The cable from my DSL modem is plugged to the Ethernet WAN port but there is no green light at the port and Airport Utility says there is nothing plugged into the WAN port. The DSL cable works fine plugged directly into my Macbook Pro.
HELP

Smokerz wrote:
use Airport Utility and select manual. Select internet then choose PPPoE and configure using DHCP. See what happens.
He won't want to do that. He already has a modem so that is doing the PPPoE related stuff. All he would need is IP conectivity. You would probably want to configure the AE to:
Create a wireless network.
Then configure it to dole out DHCP addresses and presumably NAT too.
This is assuming that your connection is like this:
modem-->AEBS-->LAN/WLAN
If you already have a router connection to the modem, or the modem is a router, i.e. DHCP enabled, then just turn on bridging but the rest should be fine.

Nothing is connected to the ethernet WAN port

I have a 5th generation AEBS and FTTH. When I plug it into the wall, it reports that nothing is connected to the ethernet WAN port, but if I plug my MBP into the wall I get an IP address and can hit the Internet just fine.
I called tech support and they said that everything looks great from their end, and that there is nothing that they can do.
What I have found is that if I plug the cable from the wall into a gigabit switch, and then plug the AEBS into the switch, everything works fine!
Any idea what can be going on? TIA!

This is increasingly a problem.. the AEBS is not actually negoiating the speed correctly with the ONT supplied by the ISP.. it happens a lot with cable modems as well.
Using the switch allows the two devices to negoiate speed correctly.
You can do the same thing with old utility..
Install 5.6 utility on your computer. Here is a method.. there are others.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
Leave the package open on the desktop so you can see the file. AirportUtility56.pkg
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. If your Mac refuses to run the software, because it wasn’t downloaded from the Apple store, go to security in preferences and allow other software to work.. this is limitation of trade methinks. You can set back later if you like.
Now drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. in finder, open the new directory, drill down.. applications, utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall version 6 (now 6.3 if you updated) so don't try.. and you cannot or should not run them both at the same time.. although I have had no problems when doing so.
Now with a real utility instead of the toyland edition you can do something about the WAN speed.
Set to either 100mbit full duplex .. that would be my first option.. and second is 100mbit half duplex.
Another alternative just popped up.. buy a crossover ethernet cable.
https://discussions.apple.com/message/23236139?ac_cid=tw123456#23236139
These cables are no longer required with modern equipment but you will find stores still stock them. For some strange reason.. in the one case reported that worked.. this indicates that the TC has some fundamental port issues.. and the mdix is not working correctly which is why the switch or manually setting port speed does.

WAN port speed on RVS4000

I have an RVS4000 with the following:
Firmware Version:
V1.3.3.5
CPU:
STAR 9202
I believe it's a v1 of the RVS4000 as I've tried to put the 2.x.x firmware and I couldn't.
My ISP upgraded me to a 100Mb/20Mb down/up plan (Quantum 100 here: https://www.highlandsfibernetwork.com/internet). However, through my RVS4000, I get the following speeds:
Download Speed 18498 kbps (2312.3 KB/sec transfer rate)
Upload Speed 19098 kbps (2387.3 KB/sec transfer rate)
Latency 7 ms
Client Time December 4, 2011 11:06 AM
Server Time December 4, 2011 11:06 AM PST
When I connect directly to the switch rather than through my RVS4000 I get:
Download Speed 45818 kbps (5727.3 KB/sec transfer rate)
Upload Speed 6240 kbps (780 KB/sec transfer rate)
Latency 5 ms
Client Time December 4, 2011 10:59 AM
Server Time December 4, 2011 10:58 AM PST
Clearly there's something wrong here, where I'm getting less than half the download speed through the RVS4000 than I do without it. From the datasheet, it states that the RVS4000's WAN port is a 10/100/1000 port, so I don't see why I should have the limitation on speed.
Can someone help resolve this?
Robert.

Hello Abudef,
I disabled IPS and verified that QOS is disabled. Now with the speed test, I get a large improvement, basically bringing me up to the speed without the RVS4000 involved:
Download Speed 41811 kbps (5226.4 KB/sec transfer rate)
Upload Speed 20550 kbps (2568.8 KB/sec transfer rate)
Latency 5 ms
Client Time December 4, 2011 07:47 PM
Server Time December 4, 2011 07:46 PM PST
Thank you so much for your help!

RV320 - vlan on Wan Port

Here in Brazil VIVO (from the spanish Telefonica group) is recently providing fiber links.
Their fiber link is being splitted into 2 vlans: one for their IPTV (vlan id 20) and another for internet (vlan id 10).
So, when they install on your house or company, they install 2 boxes: 1 ONT (Optical Network Terminal) and 1 router (which connects to the ONT and does the PPPoE auth on VLAN 10 and creates the internal VLAN for the IPTV - id20).
So, is it possible to replace their router with the RV320 and create tagged / untagged VLAns on Wan Ports and assigning ip address on each vlan (PPPoE for internet, DHCP for iptv)?
The topology is basically like this:
[Fiber Cable]
ONT
[Ethernet Gigabit]
Router
[Ethernet / Coaxial]
Network Devices
TVs (coaxial connection provided by 2. Router)
PCs (wireless /ethernet connection provided by 2.Router)

Hello,
Thank you for sharing the information about the DD-WRT firmware on other devices.Unfortunately the RV320 is not capable of such a feature, it is just not designed to do that.
On the other hand we do have one unit that is capable of such configuration, it is the RV315W router.
Here is a link to the emulator for the unit so that you have an idea of its capabilities.
http://www.cisco.com/assets/sol/sb/RV315W_Emulators/RV315W_Emulator_v1.01.03/index.asp.htm
The feature you are looking for can be configured by going to Port settings, WAN, Wan interface settings, then you can configure the desired VLANs.
I'm not sure that this device is available in Brazil. If it is not available then you may have to consider using enterprise units or other devices.
Please let us know if this is helpful.
