Speed and WAN or LAN

My iMac is ethernet wired (Cat5) to my AEB n gigabit LAN port and the transferrate is only about 10MB/s.
I think this is very slow for a wired connection.
I've tried a Cat6 cable and it did not make any difference.
Wireless speed is about 6MB/s
My network consiste of:
internet modem ->
-> D-Link 10/100 router (DHCP server)(it shows full-duplex 100)
D-Link 10/100 router (DHCP server)->
1.-EN-> AEB(n gigabit) -> USB airdisk
2.-EN-> Senao wireless AP (b/g wireless)
AEB(n gigabit) ->
3.-> iMac (Cat5 wired to the AEB LAN port)
4.-> MacBook (wireless)
5.-> Airport Express(wireless join network)-> AV receiver (optical)
6.-> Airport Express(wireless join network)-> HP printer (USB)
All components are in the same subnet. AEB is set to 5Ghz, Senao is on 2,4 Ghz.
I think my transferspeed is slow.
Can I do something to increase the speed overall?
Can I do something to increase the speed from the iMac to the EN wired AEB with airdisk?
Would it help if I connect the iMac to the AEB WAN port instead of LAN port?
Thanks for your help.

I am pretty sure that the speed restriction is not your network.
The Air Disk itself is pretty slow at writing. - The processor in the AEBS is the weak-link. Not the USB or the network.
This article shows this pretty clearly

Port speed and Wan speed

While reading Cisco documentation, router have a specific WAN speed up to 21 Mbps etc or more depending on router. You also see port speeds of 100Mbps or 1Gbps, but why are Wan speeds limited to far less on most Cisco routers.

If a router can support, for example, 21 Mbps, you don't want to have an interface of only 10 Mbps and you'll find router with 100 Mbps interface.
Same goes with routers that can support, for example, 125 Mbps. The routers will come with 1 Gbps interface instead of 100 Mbps interface.

WRVS4400N Hard Set WAN port speed and duplex???

Does anyone know if there is a way to hard set the wan port speed and duplex on a WRVS4400N V2 router?
Any Help greatly appreciated..
thanks,

Michael
I believe that these statements are true.
Auto negotiation is good when both sides are configured to negotiate. When one side does not negotiate the other side should not try to negotiate.

Lan and Wan port on Airport express

Hi guys I am wondering if you could help me out with my airport express.
I recently bought an airport express and have it set up as the following:
Router--->ethernet cable in to the Wan of Airport express--->ethernet from Airport Express Lan to computer
This is so that I have hardwired internet to my gaming computer and wifi in my room for all my devices. The problem is, however, next year I will not be in a situation that allows me the same setup. I will be too far away to run an ethernet cable from the router to the airport express. So I have decided I shall use it to join the network wirelessly and relay internet through both the Wan and Lan port (think this is called bridge mode?). I was also intending on connecting an ethernet hub to one of the ports so that I can connect multiple devices, smart tv, macbook, ps3 etc. But having one of the ports exclusively to my gaming pc.
My question is, with both Lan and Wan ports relaying internet to multiple devices, would I see a drop in performance, in particular in regard to my compter? Or is the airport express able to join both the 2.4GHz or 5GHz and relay each connection to a specific lan port?
Unfortunately I am not in a position to test this yet, lacking a 5GHz connection in my halls, so I would appreciate if anyone could help shed some light.
Thank you

is the main router also an apple product? if so, then yes you can extend wirelessly, but if the main router is an apple product, why are you bothering to extend wirelessly at all when the main router's signals should be strong enough?
if the main router is NOT an apple router, then you wil NOT be able to extend it wirelessly period.
in my experience, there are very FEW places you NEED to extend a network wirelessly, and i always recommend against it since there is a big performance decrease.
In the case of a wirelessly extended network, throughput may be reduced to less than 60 percent of that of a single device.

Which Monitoring Tool is best to monitor LAN and WAN

Hi,
CAN ANYONE TELL ME Which Monitoring Tool is best to monitor LAN and WAN.
Waiting for immediate response.
Thanks
Irshad

To start with HP open, this is SNMP-based as well. As it is around for quite a while and delivers support for many vendors, it has become sort of an industry standard. Many other vendors deliver add-ons (even CiscoWorks) to support their products via HP open. That functionality however comes with a price. If you have plenty of money an a large network to manage, HP open might be your best choice.
Cisco Works and other -start-with-C- products are typically used to manage Cisco devices. If you have a fair share of non-cisco boxes around you will find that you cannot see or do everything with them that you might want.
One special thing about CiscoWorks is that it lacks a grapical real-time overview of the network. In my opinion this is a weakness in the product. On the other hand, it has many nice features to manage all kinds of Cisco devices.
My ideal solution is to use both a generic SNMP manager, SNMPc in my case, and CiscoWorks 2000. With SNMPc I can quickly see network node status and do some bandwidth management (baselining). CW2k serves mainly to execute changes (NetConfig) and as a syslogger. It is also used to perform IOS upgrades and to store config files.
I guess this could be done with HP open as well, but our money does not reach far enough to pay for both. SNMPc costs a lot less, both in purchase and in maintenance.
Hope this clarifies things a bit.

Leo

Public LAN and WAN Addresses

Hi Guys
I am slightly confused about public lan and wan ips. We have a circuit that was installed a few months ago as a backup failover but we now want to start using it so I phoned my ISP for the public range for that circuit.
Now our internal IP subnet is a 192.168.150.xx
I was expecting the ISP to provide me with one public range maybe a /30 so I can assign an public ip to my routers external interface and PAT to that address.
The ISP instead gave me a public LAN and WAN address range both of which are public IPs. Can anyone explain what these are where in my type of network will they fit it
Thanks

As Peter says it is worth talking to your ISP but LAN addresses are usually simply another public IP block you are free to use however you want.
You don't have to use them and you certainly don't need to allocate them to physical devices on your LAN. The ISP doesn't really care how you use them either, they will simpy route traffic to those address to your edge device (see below for more details).
They can be useful if you host a lot of servers/applications accessible from the internet for example.
It does depend on the devices you have ie.
LAN -> firewall -> ISP router
in the above you use the WAN addressing for the link between the firewall and the ISP router and then you can just use the LAN address range for NAT on your firewall. Non of the LAN IPs need to be actually assigned to any interface
LAN -> firewall -> router -> ISP router
here you have your own router on the outside of the firewall. The WAN addressing would be used between your router and the ISP router. The LAN addressing would be used for the firewall to your router connection and any spare IPs can be used for NAT (usually done on the firewall).
Note that usually the LAN addressing is a larger subnet than the WAN addressing and as you say the WAN addressing is usually a /30. So the ISP uses one of the IPs from the WAN range and you use the other.
If you have been allocated LAN addresses then the ISP will route traffic to these addresses to the WAN IP you have used so make sure you use the WAN IP on either -
a) in the first example above the outside interface of your firewall
or
b) in the second example above the outside interface of your router, the one connecting to the ISP router.
Hope that makes sense.

Data package size-LAN and WAN

HI Experts,
Could anybody give explanation/Document for the below query?
When transfering R/3 to BW.How the data pacakage size is determined.?Would the size of data packets be different over LAN and WAN? Why?
Thanks
Pradeep

In transaction SBIW -> General Settings -> Maintain Control Parameters for Data Transfer (in the OLTP System), you can see and edit the default values for the source system.
If you display the infopackage in the BW system and click on the menu option Scheduler -> DataS. Default Data Transfer, you will be able to edit the settings for the infopackage and also see what's the default configuration for the source system.
You may also consult the following SAP Notes for more information (including exceptions):
[417307 - Extractor package size: Collective note for applications.|https://websmp107.sap-ag.de/sap/support/notes/417307]
[409641 - Examples of packet size dependency on ROIDOCPRMS.|https://websmp107.sap-ag.de/sap/support/notes/409641]
I don't see what difference it could have over LAN or WAN, though...

Load balance on routers LAN and WAN

Hi ;
I have a setup where i need to implement load balance on 2 routers in both sides ,LAN and WAN , and there is ASA in the LAN side , my question is that when do load blance in LAN side using GLBP how the 2 ASA's will act on this because they will have only 1 default gateway IP address .
Thanks

Not Harbi
Not entirely sure i understand the question but i'll try to answer based on a few assumptions.
It sounds like you have a pair of ASA devices on the LAN side. Assuming they are in active / failover then they will appear as one IP address to the routers - a VRRP address. When the ASA arps out for the default gateway address they will get one of the virtual mac addresses back from the AVG.
They will send traffic to that mac address ie. they won't load balance.
The load balancing aspect comes in when another host on the LAN then arps out for the default gateway and the AVG assigns it a different virtual mac address tied to a different router. But as the ASA pair always appear as one host entity they will always be tied to one of the routers at any one time.
Hope this covers what you were asking

Why would i connect a external hardrive to the airport extreme and what is the difference between LAN and WAN gigabit ethernet?

Hey just wanted to know what is the reason i would connect my external hardrive to the extreme and what is the difference between LAN and WAN ehternet. I know one is local and other is wide but can someone explain in simpler terms.

Connecting a hard drive to the Airport Extreme makes it available to be shared across all the computers on your network.
WAN (Wide Area Network) is your connection to the internet
LAN (Local Area Network) is your internal (or local) ethernet connections (computers, printers, etc...)

Lan speed and duplex negotiation

hello
when you have speed and duplex set manualy would this stop the negotiation with the other site ?

thank you for the reply
i had the folowing problem which is solved
router with manual setting speed 100, duplex full
conected to an uknown switch witth increasing input errors.
By changing all setting to auto,
speed and auto duplex got the same settings 100 full duplex but errors disapeared
My explanation to this (I have no visbility to the switch )by schanging settings to auto, negotiation started and switch changed the setting to 100 full from probably default 100 half.
and from here comes my question would be by setting the ethernet to manual will disable nogatiations ?

LWAPP ap speed and duplex

Is it possible to set the ap speed and duplex once it has joined a controller as there is nowhere on the wlc to do this.
Is there a command available after I give the ap a username and passsword with
config ap username <username> password <password> <ALL | AP Name>

Hi Pete,
Here you go my friend :)
Q. How do I set the duplex settings on the Wireless LAN Controller (WLC) and the Lightweight Access Points (LAPs)?
A. Cisco Wireless products work best when both speed and duplex are autonegotiated, but you do have the option to set the duplex settings on the WLC and LAPs. In order to set the AP speed/duplex settings, you can configure the duplex settings for the LAPs on the controller and then, in turn, push them to the LAPs.
configure ap ethernet duplex speed is the command to set the duplex settings through the CLI .This command is supported with versions 4.1 and later only.
In order to set the duplex settings for the WLC physical interfaces, use the config port physicalmode {all | port} {100h | 100f | 10h | 10f} command.
This command sets the specified or all front-panel 10/100BASE-T Ethernet ports for dedicated 10 Mbps or 100 Mbps, half-duplex or full-duplex operation. Note that you must disable autonegotiation with the config port autoneg disable command before you manually configure any physical mode on the port. Also, note that the config port autoneg command overrides settings made with the config port physicalmode command. By default, all ports are set to auto negotiate.
From this good Q&A doc;

WCCP and WAN optimisation via Layer 3 connection

Hi There,
I need some help with WCCP, however with Riverbeds instead of WAAS.
The topology of the set up is as follows:
WAN - R1 - LAN - L3 Switch - Riverbed
The clients reside on the WAN side and the servers reside on the LAN side.
My business wishes to enable WCCP on two separate WAN routers to the single Riverbed. One router is fuly managed service, and the other rout the is managed by the business IT team.
All the articles that I have come across talk about enabling WCCP on the router whereby the WAN optimisation appliance is directly connected to a interface router. I need to configure WCCP to a Riverbed that is connected to a subnet that is a single hop away via a Layer 3 switch.
My plan is to enable WCCP in the inbound directions on both the LAN and WAN interfaces, however my concern is that this design will mean the traffic passing through the LAN side interface will be optimised twice.
Can any one confirm if this would happen? If it could happen can it potentially be stopped by placing a "ip wccp redirect exclude out" command on the LAN interface.
Thanks is advance for your help.

Hi Andreas,
"ip wccp redirect exclude out" only makes sense if you have a "ip wccp redirect out"
on a L3 interface on the router.
It's purpose is to avoid redirecting an already optimised packet, comming from a L3-interface where the WAAS/Riverbed device is connected, once more.
A double redirect will, in a WAAS setup, cause the WAAS device to drop the packet, because
it suspects a routing loop... don't know what Riverbed does.
Running only with "ip wccp redirect in" on both the WAN and LAN interface will cause :
1) a packet comming in from the LAN, is supposed to be unoptimised, and will be redirected
2) a packet comming in from the WAN, is supposed to be optimised, and will also redirected
3) an IP-interface with only the WAAS/Riverbed connected should NEVER be redirected !
If you cannot isolate your WAAr/Riverbed in it's own L3 subnet (subinterface/VLAN),
and therefore have to place it in the "ordinary" LAN subnet, packets from the WAAS/Riverbed will becomes candidates for redirection (even with "ip wccp redirect in"), you'll need to use "WCCP negotiated Return", but don't know whether Riverbed supports this,
Riverbed normally uses "tunnels" on the WAN side, and this makes the WCCP setup somewhat different.
You should really consult the Riverbed documentation or their support
... or migrate to Cisco WAAS ;-)
Best regards

Anyone have intermittently lost internet connection, poor network speed and signal with new Time Capsule?

I just bought the new TC with 2gb HD. Replacing 1st Gen Airport Express. I have all the latest firmware and hardware updates. Using: iMac, multiple macbooks and airbooks, multiple iPads, android tablets, iPhones. With the new TC, I have less than impressive range and speed and my internet connection keeps disappearing intermittently. Restarts of my cable modem and the TC sometimes help. This all started with addition of new TC. I have suffered similar episodes in the past with old APE with new firmware updates. Anyone else seeing these problems? I have heard a lot of people say the new TC drastically improved their network range and speed.

The TC is failing and this happens at times with cable or fibre connections due to the WAN port having issues.
The Express uses 100mbit ethernet ports and does seem to have less issues. On the TC the gigabit is sometimes confused. If you have a small swtch around try using that between the fibre connection and the TC.
If you are using a patch cable to a wall outlet.. the other thing you can try is a crossover cable.. these are still readily available and it has helped for some people.
Do a factory reset of the TC.. and then see if you are getting the public IP onto the WAN port.
If you do there are some other issues that happen so if you can.. give us a screenshot of the wan settings you are getting in the airport utilty.
You can just cover the last few digits of the public IP.. although unless it is static it will change anyway.

Cisco RV180 and Wake-On-Lan (WOL)

Hello,
I got a RV180 (firmware version: 1.0.1.9) and I am bit surprised by the lack of the configuration flexibility...
I am trying to use Wake-On-Lan (from internet) to wake up a machine in my home (trying to be green and not keep the machine on all the time, just when i need it).
The configuration is quite simple:
Work machine ----> (internet) ----> (WAN) RV180 (LAN) ----> Home Machine (off, linux, wol enabled for UNICAST and Magic Packet - flags "ug")
What i tried so far:
1. All the following RV180 settings together:
   a. Used Port Forwarding from the WAN IP to the Home Machine IP (UDP port 7 and 9)
       - i had no choice but to put the Home Machine's IP address, since i cannot put the BROADCAST address (xxx.xxx.xxx.255) <- forbidden in the configuration page (i wonder if a new version of firmware allows this)
   b. Used Static DHCP to pair the Home Machine's IP to it's MAC address
   c. Used IP/MAC binding for the Home Machine
2. All the following RV180 settings together:
   a. Created a PPTP VPN connection
   b. Connected from the Work machine (obtained a LAN IP, can ping the Home Machine if it is on)
   c. Tried to send a broadcast message to LAN (no success !)
3. I also tried to activate the MULTICAST and BROADCAST WOL flags on the Home Machine but it seems that it receives some messages and the machine wakes up in a very short amount of time after i shut it down (it seems that RV180 sends some messages over LAN by itself).
In all the 3 possibilites above i was not successful in using WOL....
Is there any possibility to use WOL from internet in this configuration ?
Are there new options that will allow WOL from internet in the latest firmware ?
Any advice is appreciated
Thank you
Mircea

Dear Mircea,
Thank you for reaching the Small Business Support Community.
I was researching about your concern and found several people with the same inquiry where they were told WoL is not a supported feature on these Small Business Routers and that I think is a correct assumption, however I found the below threat where someone with a similar case scenario as yours were able to make it work, it's on a different RV router but I thought I may be interesting for you to check;

Wifi speed and the new Apple TV concerns

One of the great things about my classic ATV is that I can start downloading a movie before dinner, and know that my viewing experience later won't be subject to variances in the wifi speed. In my experience, wifi speed and reliability can vary widely - and my worst nightmare is a video that stutters or freezes.
I new the new box has the faster modern chip, but I'm concerned Apple has no control over what might be the weak link: the wifi connection.
Is it time to make a run on a couple of classic boxes? Are they still in stock anywhere?

The problem is that all services are bundled with your Apple ID ([email protected]):
Your iCloud account (Mail, Contacts, Calendars, Reminders, Notes, Backups, etc.),
also iTunes & App Store purchases (Music, Movies, TV Shows, etc.),
and the iTunes Match services.
(I guess that all your devices - yours and your wife's are connected to one iTunes library, right?)
If you want that your wife gets her own iCloud account for Mail, Contacts, Calendars, etc. but gets also access to your media then you have two set up two things on her device:
iCloud (Settings > iCloud) with her account (e.g. [email protected])
and
iTunes & App Stores (Settings > iTunes & App Stores) with your account (e.g. [email protected]).
In this case she gets access to your library and could use the same iTunes Match account.
