Ethernet port to 100 speed

all,
can we force a router ethernet port to run at 100 meg? as far as i know this runs at 10 meg. can i configure it to 100 meg and duplex to full so that it communicate with a switch

hi jon, here's a show version of our router:
cisco 2610 (MPC860) processor (revision 0x202) with 61440K/4096K bytes of memory
Processor board ID JAB0314034T (1672352097)
M860 processor: part number 0, mask 49
Bridging software.
X.25 software, Version 3.0.0.
1 Ethernet/IEEE 802.3 interface(s)
1 Serial network interface(s)
32K bytes of non-volatile configuration memory.
16384K bytes of processor board System flash (Read/Write)
Configuration register is 0x2102
the ethernet interface will be connected to the LAN through a fastethernet port on a 2950G switch. my boss wants to run the connection at 100 meg. is this possible on ethernet port?

Ethernet port on 2010 iMac won't operate at Gigabit speed, but requires router to be set at 100 Base-T.

For almost a month I have been experiencing internet connection dropouts with my vDSL line, which had previously been stable for about six weeks since I changed ISP. I have an initially wired setup, from the router to my Time Capsule WAN port and from there to my 27" iMac Ethernet port. I bought new Cat 6 cables on setup.
During the router setup I was advised to set the active port at the Gigabit setting. Finally having discounted all other possibilities, the router manufacturer support engineer suggested I reset this back to the default 100 Base-T setting: and this has resulted in a stable connection once more.
Surely my iMac should offer functionality at Gigabit Ethernet transfer speeds? Otherwise the Airport home network is dependent on what my computer's Ethernet port can manage.

If you Google for non Flash speed test site you will find at least two, I have no idea how good they are hence not putting any links in the post.
As for pin pointing the problem, the only way I know short of having access to the internals of the router and TC including firmware source and test equipment is by producing the fault and swopping the various pieces of equipment out. Having access to the internals is way beyond anything I can do and swopping the parts out seems expensive.
From past experoence of Gigabit issuses I had it was usually down to cabling or faulty connections in the RJ45 sockets, this was quite common. As for the incompatibilty, one way to test is to put a 1Gb switch between the router and the TC.
I would not presume either the router or cable are good until proved.
There is always the possiblity that more than one piece of equipment is faulty, rare but I I have had it happen before.
Not a lot else I can say, perhaps someone else as more thoughts and can help.

Ethernet port speeds on the new airport extreme

What is Apple's reason for making the ethernet ports on the new Wifi Extreme 10/100 instead of the now common 10/1000 Gigabit variety?

The most obvious reason is that Apple realizes that few home users would benefit from the higher speed when using Apple’s base station. Most users doing professional type work would be using a Mac Pro for example and most likely professional type routers, themselves quite different from consumer routers such as Apple’s base station.
My guess is that the next base station will have the higher speed. Methinks Apple rushed into the latest with “N” to keep up with the router competition, which is also offering “N”. I suspect the next iteration of the base station will have the higher speed.
Of course the higher speed is useful only for a LAN. Speed to the internet is governed by the ISP used. If you have a home LAN with only a few computers attached, you wouldn’t likely see much of an improvement with the higher speeds depending on how much you are transferring. For most home users, that is not very much for a given transfer.
The higher Ethernet speed is not the Holy Grail of speed improvements. I suspect more theoretical than real when applied to the world of home users. The latest base station not having the higher Ethernet speed is not a big deal.

Ethernet Port Speed

Do all Ethernet ports slow down to 10 Mbps when I plugin my old PC to the Airport Extreme?
I understand that the 4 Ethernet ports all support 10/100/1000 Mbps. I have an old PC with a 10 Mbps Ethernet network interface card and I think my DLS modem also has a slot Ethernet port.
So I wonder if my MacPro and the MacBook Pro will be able to "talk" to each other at the full 1000 Mbps?
Thanks for your help

I believe that the other ports will continue to operate at their full speed. You can determine the speed of a port with the "Info" pane of Network Utility.

Ethernet Port Speeds on PowerMac G5

I just recently upgraded my cable modem and have it connected via a new ethernet cable to my Time Capsule.
My Mac Book Pro (2.4 GHz) and my 2004 PowerMac G5 (2.0 Ghz) are both connected to my Time Capsule via new ethernet cables.
I have been running SpeedTest.net on both computers and on my MBP I can achieve 32MB/s Down and 5 MB/s up. When I try the same test on my PowerMac G5 the speeds are 5-15 MB/s Down and 1 - 3 MB/s Up.
Since the Modem and Cables are new, both machines have Giga Ethernet Ports, and are connected to the the same Apple Router the I would think the problem is with my PowerMac. I am tempted to buy another ethernet card to fix this but I have a couple of questions before I do.
1) Any suggestions on really fast/dependable ethernet cards?'
2) I downgraded the Ethernet ports speeds to 100MB/s, saw some improvement, but not enough, is there anything else that can be adjusted with software (already have the latest firmware)
3) Any software to measure or test the port speeds other then Network Utility ?
Thanks,
Kevin

UPDATE -
I readjusted the Ethernet Port Speeds to 100mbs and rebooted the PMG5 and now I am getting much higher download and upload speeds from the net/router
Its seems the reboot made the difference - When in Doubt - REBOOT !

Will on-board Gigabit Ethernet ports on a Cisco 3845 support a 100 Mb SFP?

Hi,
This is a very specific question - hopefully someone has tested this or run into this scenario...
I was trying to connect a Cisco 3845 router to a 100 Mbps circuit. Specifically, I was trying to connect this circuit to the on-board Gigabit Ethernet port (Gig 0/0). This is the port that can be used as either an RJ45 or SFP slot. The only SFP I had was a multi-mode 100 Mbps SFP. When I hooked it up to Gi0/0, I got a message saying the SFP type wasn't supported on the chassis.
I was able to deploy the 3845 and since then I haven't had the correct hardware to recreate the exact scenario. Has anyone experienced this? Is it simply because Gigabit interface on a 3845 won't support a Fast Ethernet (100 Mbps) SFP?
Thanks.

Not all SFP's will just plug in and work. Here are the SFP's that are considered compatible with the 3800 series ISR's.
GLC-LH-SM= Gigabit Ethernet SFP, LC connector, LX/LH transceiver
GLC-SX-MM= Gigabit Ethernet SFP, LC connector, SX transceiver
GLC-ZX-SM= 1000BASE-ZX SFP
CWDM-SFP-1470= Coarse wavelength-division multiplexing (CWDM) 1470-nm SFP Gigabit Ethernet and 1G/2G Fibre Channel (FC)
CWDM-SFP-1490= CWDM 1490-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1510= CWDM 1510-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1530= CWDM 1530-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1550= CWDM 1550-nm SFP Gigabit Ethernet and 1G/2G FC
CWDM-SFP-1570= CWDM 1570-nm SFP Gigabit Ethernet and 1G/2G FC

TC ethernet port question

Hello. My apologies if this has been covered before, but I'm having difficulties connecting one of my computers via ethernet to a new 2TB TC. Yesterday I replaced my old TC by copying its configuration file and importing it while setting up the new unit. This seems to work out fine for all the wireless and wired clients except for one, my Mac Pro, which is connected to an ethernet port on the new TC. I can't seem to find a way to diagnose what's gone wrong. Network Preferences recognizes that the ethernet cable is plugged into the Mac, but it has a very different IP address than the other clients and can't connect to the network or the Internet. I suspected either a port on the new TC wasn't working right or something was wrong with the cable itself (though everything was fine before the TC replacement) but after reordering the ethernet port connections and successfully connecting my laptop to the network through the same ethernet cable my Mac Pro was on, I realized all the connections appear to be fine and the problem is likely the Mac Pro.
I eventually connected an old Airport Express to the same cable and was able to bridge the network to the Mac Pro wirelessly, but I'd love to figure this out if there's something I'm doing wrong on the Mac Pro (I'm definitely no networking expert). If it's potentially the built-in ethernet that's the problem I'd like to know that too, before my warranty runs out.
If anyone's got any ideas I'd really be grateful.
thanks,
Paul
I should add I've tried Network Diagnostics and Network Assistant to try a new location, without any luck.

Check the connectivity leds come on.. both on the TC and the Mac Pro. although I am not sure if it has connectivity led.
Try forcing the network card to a specific speed.. slower being better.. to test at least. Set to 100mbit full duplex. You do this via the system preferences for that network card.
If you still have the old TC plug the Mac into it.. if it works set it to bridge and plug the new TC into the old one. What happens?

Is the address you are getting 169.254.x.x which is a self assigned address and means the ethernet card cannot connect to the TC?? Try using a manual setup as well as the manually assigned speed. If the TC is at default, assign 10.0.1.100 say to the ethernet and 255.255.255.0 with router and dns set to 10.0.1.1 and see if it works.

AIR-CAP702W local ethernet ports

Hi all,
The new AIR-CAP702W AP have 4 10/100/1000Base-T local Ethernet ports.
On the data-sheet it's written "for wired devices connectivity".
http://www.cisco.com/c/en/us/products/collateral/wireless/aironet-700-series/data_sheet_c78-728968.html
That's very good, but how do we manage the traffic on these ports?
Are we able to configure theses ports in access-mode with different VLAN-IDs?
So in that case the uplink of the AP should be in trunk-mode.
And where do we configure the ports of the AP, on the WLC?
Or is the traffic from the devices connected into these ports encapsulated into CAPWAP tunnel, like the wireless data traffic, and is terminated into the WLC(s)?
In that case, can we choose what port is associated to what VLAN/SSID on the WLC?
Or something else maybe?
Thank you for your help.
Jerome

The 4 x 10/100/1000BASE-T local Ethernet ports support half and full duplex mode, auto-negotiation, and MDI/MDIX Auto-Sensing. Devices you connect must support auto negotiation if you connect with another mode, say hard configured speed and so on. The port may not be enabled and depending on the version of code, for example 7.6.100.120 the initial release, the ports are not managed.
For now, (until more control is added in the software) all the LAN ports are locally switched, are mapped to the 702W VLAN, and do not appear on the Wireless LAN Controller or AP.
Initially, the ports are disabled and may be enabled manually via CLI.
This was done to minimize any security risks. Here are the CLI commands to enable the ports.
(Cisco Controller)> config ap lan <port id> <enable/disable> <AP-NAME>
(Cisco Controller)> show ap lan <port id> <AP-NAME>
(Cisco Controller)> show ap lan port-summary <AP-NAME>
Hope that helps.

WAN Ethernet Port Settings?

Under the Apple Airport Admin Utility/Internet tab there is a button marked WAN Ethernet Port. This button gives you several options, including "Automatic", and then four other options referring to what I guess are port speeds, and the terms "Half Duplex" and "Full Duplex". Any one have a clue to what these are/mean? What should I choose to maximize my Base Station?
I'm running a LinkSys Cable Modem into my Base Station. Right now I'm supposed to be getting 8 MBps service thru Comcast. But I'm only maxing out at about 768 kbps.
eMac 1.25 Mac OS X (10.4.6)

Those all have to do with ethernet port speed and transmission of data. Automatic means the ethernet port will try and sense what it is connected to and set the correct port speed and duplexing level. The duplexing means transmission of data. Half duplex will transmit data in just one direction at a time and full means that it will transmit and recieve at the same time. A walkie talkie is an example of half duplex and a telephone is an example of full.
Usally setting it to automatic is the way to go but you want to make sure each side is the same. Make sure whatever your cable modem is set to (Automatic, 100/Full, 100/Half, etc.) is the same on the WAN port of the AE.
If not you will receive CRC errors etc causing slowdowns and retransmission of data.
I hope this helps.

Can the number of ethernet ports be increased from 3?

Clearly I know that we cant weld another port onto the airport extreme but, I have 5 devices I need to run through the wireless network and the box only has 3. Is there any way to increase this number with perhaps a splitter or some add on device? All 5 will never be active at the same time but, the thought of having to go behind the port daily and swap out cables is not an option. THX

Will the ports enabled by this product also be capable of "n" speeds if I purchase the new N router?
Sounds like you got wireless and wired a bit mixed up. The Ethernet (wired) ports on the AirPort Extreme Base Station (AEBS) are rated at 10/100 Mbps. The AEBS's wireless is 802.11a/b/g/(pre-n)-compliant...meaning that theoretically it can handle speeds from 11 Mbps to 540 Mbps.
Adding an Ethernet switch to one of the AEBS's 10/100 Mbps Ethernet ports, will only provide 10/100 Mbps throughput, not 802.11n speeds.
Anything that is a little more aesthetically pleasing than that big blue box? Anyone else make such a device?
Linksys has several other models, as well as, Belkin, D-Link, & Netgear (to name a few).

Ethernet port on QIP7100 2

There's an Ethernet port on the QIP7100 2 STB (the manual states that it's 10/100). Does it have any use? Specifically, can it be used instead of the coax connection?
Thanks,
Willie
Solved!
Go to Solution.

Its there because Motorola markets to other than Verizon. But Verizon does not use it or activate it. Must be COAX and MOCA internet connection.
The same does not apply to the routers, most/all of which have a wan Ethernet and 4 regular Ethernet connections. The 4 regular Ethernet connection can be used. The wan connection can be connected by Ethernet to the ONT and used, but that does require you to call and ask for it to be activated. Note that those with FIOS speeds above 100 are connected that way. If using the wan Ethernet and you have FIOS TV both coax and wan connection remain connected to the ONT.

Using both Dual Gigabit Ethernet Ports

Using both Dual Gigabit Ethernet Ports
If I plugged both of my ethernet ports into my LAN switch, that would double the bandwidth to and from my machine. A switch does not used shared bandwidth like a hub does. I realize that it won't speed up any of the other devices that are plugged into the switch. Regardless, I would have the capacity for double the bandwidth to my machine.
All LAN cables are CAT6 and the switch is 10/100/1000.
The question is, would Mac OS X 10.4.7 utilize both ports (soft of the way it uses multiple processors)?

It's easy to try... it's call "Link Aggregation"...
http://docs.info.apple.com/article.html?artnum=304120
You get to it by Network>Show>Network Port Configurations>New then Port in the popup, then you schould see Port Aggregation. Selt the two ports you wish to combine.

Need More Ethernet Ports

I have an 500gb APTC and in need of more Ethernet ports for my small home office. I considered picking up a new switch, but first wondering if digging out from the mothballs, a "Linksys BEFSR41 EtherFast Cable/DSL Router with 4-Port 10/100 Switch" would do the trick. ?? I have 3 Mac's in my office that are hard wired along with an Ooma Telo that also needs a port.To add on top of this I also have Zyxel Powerlines throughout my house, the main one is is my office also where the cable comes in.
Taking all this into account and assuming the Linky would do what would be the best order to set this up?
Would the ceiling of "10/100" (not "10/1000") on the Linky be a concern for our newer Macs?
Thanks for any help or recommendations.

Thanks Bob, as cheep as they are I'll just pick up a new switch for the speed.
As far as the power line's I have these along with these. They're the same, yet one type allows passthrough and the other does not. I'll admit that I didn't thoroughly research these, but see that they're rated as "Gigabit" and I am running cat6 if it matters.
My network goes like this:
Cable comes into the house then to---> Surfboard Modem (SB6121) ---> Ooma Telo ---> APTC ---> Powerline.
The APTC has two (not three as mentioned earlier, one's WiFi) office computers hardwired to it, A Mac Mini and an iMac. The other APTC ports go to the Powerline and the Ooma Telo as mentioned above. If it matters in my family room I then have a ZYXEL Powerline PLA225 which is basically the same as the others, but has 4 ports. Two of those are used by an Xbox One and a Roku 2. Then upstairs in the master I have two Powerlines connected to an ATV and a Roku 3. Then lastly I have two kids rooms with the same Powerline's in them and Mac Mini's connected to them. Other computers and printers run on WiFi.
Just as a note I checked Network Utility and Link Speed is 1Gbit/s. The only reason I mention this is the fact that my download speeds have been terrible for a couple months and not sure why. I've changed nothing in that period. The reason that I need the additional ports is so that the Ooma Telo isn't in the middle of my configuration, but instead after the APTC somewhere. I have suspicions that the Ooma is the culprit, but just guessing.
In case you're not familiar with the Ooma Telo it's basically a VOIP box. The back looks like this. The two ethernet ports are "Home Network" and "To Internet".
Other suggestions?

How do I add an airport extreme to a cable modem with only one ethernet port, while keeping that port connected to my Mac?

I have a mac pro connected by ethernet to a cable modem via ethernet. There is only one ethernet port on the modem.
I want to keep the Mac connected via ethernet for speed. Is there a way that I can add an airport extreme to this set up - for my ipad and roku, and for guests to use - or do I need to buy a router to put between the modem and the mac?
If I need a router, what kind?
Thanks.

The modem connects to the WAN "O" port on an AirPort Extreme router.
The Mac Pro connects to one of the three LAN <-> ports on the AirPort Extreme router.
Or if you do not need the ability to connect a hard drive to the USB port on the router, you can save a bit by using an AirPort Express.
The modem connects to the WAN "O" port, the Mac Pro connects to the LAN <-> port
Either the AirPort Extreme router or AirPort Express router will allow up to 50 wireless device to connect.
There are many other wireless modems offered by other manufacturers as well.

Airport Extreme - creating a wired local network from a cellular hotspot without ethernet ports?

Forgive the book I've written below, please. I generally think too much info is better than not enough... I'm looking for assistance and/or suggestions since I have been unable to locate solutions on my own so far. Searching this forum has found a great number of "sort-of" related things, but all of them so far appear to involve apple-only hardware or upstream network devices which have ethernet ports. Nothing that seems to match my situation enough to extrapolate out. Maybe I'm just using the wrong keywords. Anyway....
I've recently moved to a particularly rural area with no wired internet access to speak of (well, I suppose there is dial-up, but... yeah). I've tried several different wireless varieties including satellite, the AT&T Elevate 4G hotspot and a service that used an EVDO-cellular solution(a sprint-based reseller). The former had serious latency issues which I had predicted and so was right-out. The last had signal coverage problems which their maps did not accurately reveal. Their potential mitigation was to have me invest even more money into a super-mega antenna to be roof-mounted. And even that was an uncertain fix. The AT&T solution with the 4G hotspot has been AMAZING so far and I love it. Coverage is great, latency and bandwidth fantastic.
I love it but for one exception, that is. Connectivity options.
There is a particularly limited number of WiFi connections available and only a USB network adapter for a single computer. None of my wired-only network devices can connect directly and I have significantly more WiFi connected devices in general use than the device supports.
I have an Airport Extreme that I was using as my primary connection point through a FiOS router at my previous home(and both the satellite and EVDO modems at the new place). Never had any problems with it when feeding its WAN port with one of the various routers' LAN ports. However, as has been evident by reading all sorts of posts here and elsewhere, having it connect via WiFi to the Elevate means that the ethernet ports are disabled. Not terribly useful.
The Elevate has no ethernet ports. Only WiFi and USB network connectivity.
The Elevate does not appear to have settings available to create a WDS network-- so it cannot be "Extended" via those methods, either, as far as I am able to tell.
So these are some thoughts I've had. Before I invest the time and money into them(both of which are in extremely short supply lately), I'd like to know if anyone else has already solved the issue or can tell me definitively whether these ideas, or some I haven't thought of, will or won't work. Any helpful feedback or thoughts would be sincerely appreciated.
Options I've considered, but are uncertain:
-A Wifi/Ethernet or even ethernet-only router which has a USB WAN uplink(I've had a few bites on searching, but nobody seems 100% clear on the capability for the models I've located). I could plug the Elevate into that USB port and then from there I'm golden. If this is the best option, then can someone recommend a brand/model that they know will work in this way?
-WiFi Access Point (Airport Express, maybe?) that will connect to the elevate via WiFi, and then use its single Ethernet port to serve as the APExtreme's WAN uplink. (I don't know if this will work at all, actually...)
-Connect to the computer via USB, run some kind of network bridging software (which I don't know what the heck that would be) to bridge between the USB Network and the Ethernet port, then run a hard wire from there to the APExtreme's standard ethernet WAN uplink. This is going to be a "last resort" option since it involves software I'm unfamiliar with, even unsure of availability for Mac, and requires the computer to be running and configured properly at all times. Given the way my kids abuse a computer, I can't be certain of anything involving this option.
-Some secret method of turning on WDS capabilities in the Elevate which would then allow my existing base station to become a second node in the chain. I really wish someone could tell me this is possible if only I'd push the right buttons. I see this is as the absolute best option, if it can be done. Cheapest, anyway.
Current set-up:
AT&T Elevate 4G hotspot
WiFi connected devices(rotating since Wifi connection count is limited): Mac PC, 2 iPads, 3 iPhones, Apple TV, a Nokia mini-tablet, a Kindle fire, Wii, XBox 360, an old dell laptop issued by my office.
Apple Aiport Extreme base station
Wired connections: blueray player, television, satellite TV pay-per-view uplinky device thing.
Please, tell me your thoughts?

Had the same issue here. Here is the best solution I have found so far:
Hotspot + Pepwave Max On-The-Go (w/ Load Balancing) + Airport Extreme
I have a VZW MiFi, but I believe this set-up will work with other hotspot devices. I actually have 2 MiFi Hotspots with a monthly allowance of 20G each. They are plugged directly into the Pepwave router (aka, tethered). (Note: you have to have the right cable to do this. The one that came with my Hotspot was only for charging.) If, for some reason, you cannot tether with your Hotspot device, you want a router that offers WiFi as WAN. The Pepwave will do this. The Pepwave is connected to my Airport Extreme via ethernet cable. I have the WiFi on the MiFis and the Pepwave turned off. So the only visible network is my Airport Extreme. The Pepwave is essentially just functioning as a modem.
I used to have a Cradlepoint, but I did not find it very user friendly--too complex for home use. The Pepwave Max OTG is awesome. I got the one with Load Balancing so it allows you to connect up to 4 cellular devices. If you only need the one Hotspot, you can just get the cheaper Pepwave Max OTG. The Pepwave allows me to run off one of the MiFis until I hit my 20G/month allowance, then it automatically switches to the other one. That way I never max-out on my monthly data allowance. Additionally, it gives you a real-time, hourly, daily and monthly running tally on data usage.
The guys at the 3Gstore are excellent and can help you figure out the best solution for your situation.
