Ethernet cable length

Granted this isn't exactly an MBP question, but it relates to it. Is there some sort of limit on how long an Ethernet cable can be? Basically I would be running a 100' cable from where the router is to my new home office which happens to be on the other side of the house.

That 100' cable should be perfect. Rember all those office buildings with hundreds of feet of Ethernet cable in them.
Happy computing.

  • Ethernet cable length from route

    Love this forum: After a few years of use this is the first time I haven't found an answer by searching!
    Everyone seems to say that the limit of ethernet cable is 100 meters but in two apartments with different routers I have not been able to get a connection between (two different) the router and my computer over about 25 feet. I'm using a (seemingly) top of the line d-link wireless router but maybe its too weak. Can anyone suggest a router or switch that will reach 50 feet or more?
    Thanks!
    (P.S.) wireless is too slow to back up my iPhoto library, which I want to back up to a Linux Ubuntu PC home server.

    Thanks for responding!
    The iPhoto library is about 25 gigs at the moment (iTunes is another 15gigs), and can grow pretty quickly. I do have 250gig firewire drive for back up next to the computer but I feel my life of photos in that library and want a second backup in another room of the apartment. I installed Ubuntu on a Windows PC so I could use NFS sharing with the Mac (works great except for speed).
    The specifications all talk about maximum theoretical lengths and none of the manufacturers discuss actual cable lengths. Everyone seems to assume that any router will do the job.
    I did find an interesting post at the bottom of this:
    http://discussions.hardwarecentral.com/showthread.php?t=172404
    so I've order a couple of 50ft cat5e cables with factory attached jacks to see if it was my crimping color order that was at fault (which doesn't really make sense but it's the only thing I've found)
    Should get them in a few days...

  • Maximum Cable Length

    This might be a stupid question, but... Is there a limit in cable length, beyond which Airport Express is unable to deliver a strong enough signal. My cable is not that long, maybe only 15 meters or something like that.
    I have Airport Express (Gigabit Ethernet) and since I'm renovating my house, I had to move AEP and computers from one room to another (with one room in between). ADSL modem stayed in the room, only AEP and computers were moved.
    As I did so, my internet connection (cabled trough AEP and/or wireless) became extremly slow and unstable, uploading only few bytes per second (it took half an hour to upload 300kb file).
    Scenario 1 (extremly slow):
    ADSL modem --15m--> AEP --> Desktop
    Then I moved AEP back, and connected desktop computer in the new room, but desktop computer is unable to connect (limited or no connectivity)
    Scenario 2 (no connectivity):
    ADSL modem --> AEP --15m--> Desktop
    But, if I connect my desktop directly to ADSL modem, everything works just fine (but of course, I don't have wireless).
    Scenario 3 (works fine):
    ADSL modem --15m--> Desktop
    My ADSL modem is able to auto-negotiate cable type (CrossOver or normal), so I don't think wrong cable installations might be a problem....

    Hello PetLj. Welcome to the Apple Discussions!
    Is there a limit in cable length, beyond which Airport Express is unable to deliver a strong enough signal.
    The maximum CAT-5 Ethernet cable length would be 100m. However, cable length and wireless strength are not directly related.
    However, it is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your AirPort Express from providing a good clean signal to wireless clients.
    I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
    For Macs:
    o KisMAC
    o MacStumbler
    o iStumbler, or
    o IPNetMonitorX
    For PCs:
    o NetStumbler
    o WiFi Hopper
    o WiFi Owl
    o WiFi Manager

  • Question re. Ethernet cable going from HH3 to Mode...

    Guys,
    Do any of you know whether you can use any Cat5e ethernet cable from the Red Infinity socket on the HH3 to the LAN1 port on the Openreach modem as opposed to the one with the red terminals provided by BT? I only ask as like most of you I'm sure, my HH3 and modem are no more than about 20cm apart so I'd prefer to use a much shorter cable than the one supplied.
    And does that also apply to the RJ11 going from the Master Socket to the DSL port on the modem (i.e. will any RJ11 do)?
    Cheers in advance. 
    You won't get to ride the racehorse...until you've ridden the mule.... - RogerB 13/04/2010

    from the homehub to modem, any decent cat5/cat5a/cat6 cable will do. as for the rj11 cable to phone socket, if you know a good i.t. guru, he could knock you up a cat5 cable with rj11 connectors at each end to your specific length, or, if you don't know an i.t. guru, you could scout the net for the cable. I use such a cable and it is far superior to the one supplied by bt.
    Also, if you feel competent & have the tools,you could do it yourself. i posted howto do this previously, so a quick search with my moniker should find it
    free your computer, use opensource
    i'm a linux user & very happy about it

  • USING LONG ETHERNET CABLE FROM HUB TO VISION BOX

    Hi, just ordered bt vision and wondered if anyone could tell me if it is ok to connect the hub to the vision box with a long Ethernet cable, 20m long. From the video clips on setting the system up they say if over 2 meters you must use power adaptors which uses your houses electrical ring main to send the signals. Do you lose picture signal or does it slow down connection to bt. Or do they give the power adaptors to make it easier for people so they don't have to run long Ethernet cables.
    Many thanks
    Solved!

    Hi and welcome to the forum.
    I also have an ethernet cable around 20m long and works ok, I think BT say the 2m rule so customers do not have long lengths of cable around their house, good old elf'nsafety.

  • How can I setup without an ethernet cable?

    Hey guys,
    I just got my Time Capsule... I have a wireless modem existing for internet - ethernet cable from the wall to the modem.
    I'm wondering how I can go about setting up my Time Capsule without an ethernet cable?? I don't have an extra one.  :S
    Any guidance is much appreciated
    Thanks!

    Check the setup manual to verify that Apple does not support a "wireless only" type of configuration of the Time Capsule.
    You will need to purchase an Ethernet cable to connect the Time Capsule to your wireless router. Connect from a LAN <-> port on the wireless router to  the WAN port on the Time Capsule.
    You can use virtually any length cable that you want.

  • Ethernet Cable for BT hub

    Apparently, I have either a problem with one of my extension sockets, or it is a piece of phone equipment plugged into one extension socket that is draining the other one thus rendering me with a Internet connection speed that is lower than I could get if I plug my hub into the master socket.
    Obviously I'm going to try a and plugging the equipment to see if my Internet speeds up. If it doesn't, I decided to move my BT home Hub into the room that houses the master socket. However, this room is probably 40 feet away from where my computer is housed. I know that the maximum recommended length for an ethernet cable is around 100 m so I don't have to worry about this. However, it's still quite a long way so what would you recommend I use for cable, I'm contemplating going for a good quality cable to cut down on any loss that may occur because of the added distance between the computer and a hub

    I have 2 x 50 meter ethernet cable joined to make a 100 meter run running from my router in the living room to my office upstairs at the back of my house and haven't noticed any drop in quality or speed,I get my cables from one of the Ebay shops at a reasonable price.

  • What is the best ethernet cable in the Apple Store?  I see they have CaT6 now and gold plated ends.  is this worth buying since my old ethernet is kind of trashed?

    is any one of the Belkin ethernet CAT6 better than the /cAT5 since my ethernet cable is trahed?  Any sugggestions on what ethernet is most like the current ethernet cable that you plug into the MBP and the hotel room? (for example)

    Actually, I'm an outstanding researcher in medicine.  I keep people alive.  All you do is spend extra money to keep Monster executives rolling in cash. 
    Evidence:
    CNET
    Crutchfield (who sells this stuff and would like to make more money)
    I could go on.  But you have your own belief, not establish but supporting evidence, and spending money for a marginal difference.  Do you understand the physics behind the gold plating?  Well, I do, and I reject it, based on both the physical chemistry of the metals and, of course, the physics.  Again, if you ran gold from one end to the other, then maybe you could convince me of a marginal difference in conductivity of the electrons, but because the gating material will be the copper/aluminum/steel or whatever is used before the gold plated ends, there will be no difference.  Morever, the quality of signal is dependent on other factors including length of the cable, which impacts resistance (see metals above).  This is basic basic basic Physics 101.
    Now, the worst part of this.  You posted a question, asking for opinions.  I gave one based on evidence provided by others who actually did study this.  They indicated that there was no difference between HDMI cables to use as a proxy for ethernet cable.  I made no value opinion, just here was one piece of data.  You returned with a strawman fallacy based on your opinion.  Further, you wasted our time here by posting a question for which you already had made your own conclusion.  I assume you were looking for validation of said conclusion, instead of being openminded to the potential of being incorrect.
    So, I'm happy that you wasted my time, since it is free.  Good luck with your cable.  And rudeness does not get you far.

  • What is an ethernet cable?, what is an ethernet cable?

    what is an ethernet cable?, what is an ethernet cable?

    It can be purchased under the name of Ethernet cable, Cat-5 cable, Cat-5e cable, and Cat-6 cable.
    Most ethernet cables now sold are Patch-type (also called Straight-through), though older Macs (pre-2000 and some 2000 models) needed to use a Crossover-type cable.
    They can be purchased in a wide variety of lengths and colors.

  • Cable length limit on the so-called "Internet" port?

    Is there a limit on the cable-length when connecting an Ethernet cable to the so-called "Internet" port on a WRT54G router?
    I assume this is a standard 10/100 Ethernet port, since I am connecting this to the Ethernet port of my DSL modem. Since the Ethernet standard defines a maximum cable-length of 100 meters when connecting any 2 Ethernet devices, I should be able to use a cable up to this length when connecting 2 Linksys routers together.
    Here is what I want to do:
    DSL Modem-->Linksys Router-->Linksys Router
    My first Linksys WRT54G router is connected to a DSL modem. I want to put a second WRT54G Linksys router in a different building, and connect them with a 100 meter Ethernet cable, connecting the remote end to the second router´s "Internet" port, and the other end into one of the first router´s available 10/100 ports. This will allow me to create 2 wireless signals, with 2 different DHCP scopes and 2 different SSID´s, basically allowing me to extend the range, with the 2 routers connected with a physical wire.
    This works when connecting them with a short, 2 meter cable. Using a short cable I am able to associate with the second router´s SSID, get a DHCP address from that router, and then turn on RIP on both routers and have traffic route from the second router to the first one and out to the Internet successfully.
    However, when I replace the short cable with a longer one, either 80 meters or 100 meters, I don´t get a link light between the routers. I do get a link light if I connect to a 10/100 port on both routers, but RIP doesn´t seem to want to exchange routes on the second router out anything other than the "Internet" port. Moving the cable back to the "Internet" port fails to produce a link light (unless I use a really short cable, which does produce a link light).
    So my question is this: from a Layer-1 perspective, is the "Internet" port an Ethernet port that enforces a cable-length limit that doesn`t follow the standard 100 meter rule?
    --- Christer

    well..the internet port is definitely an ethernet port...however, it is not supposed to limit the cable length .. try a 50 m cable and check whether it works...because my friend had a similar kind of an issue and it worked fine with a 50 m ethernet cable ..

  • E1 Cable Length Limitation

    I need to know the E1 cable length limitations,in meters? Actually i've a customer who needs to extend their E1's from the basement to DataCenter Room and you people know the UTP Cable limitation. So which type of device should i refer to them for this purpose.

    UTP gauge 22, typical attenuation, should cover 1000 feet ( > 300 m) without problem.
    Make sure you use proper cable and respect the pair twisting, that is NOT like ethernet.

  • Cable length between modem and Home Hub 3

    Hi can anyone tell me if there is a maximum length for the red RJ45 cable running between the engineer installed modem and the Home Hub 3 unit. I would like to move it to a more convenient location using a RJ45 cable run.

    You can run an ethernet cable for up to 100m before you have any problems.

  • Are cheap Ethernet cables a bad idea?

    Like HDMI cables, I see a wide range of cost for the same length and Category level Ethernet cables.
    Example: Apple has a Cat 6 15' cable for $20. BestBuy has one for $25, HomeDepot for around $19 and Amazon has one for like $5! There are plenty of Cat 6 15' Ethernet cables online for under $7. Some with free shipping even!
    Do you get what you pay for here?
    There is lots of controversy wit the ultra high priced HDMI cables that some say these are a total marketing ploy and totally unnecessary and a waste of $$
    Is that true with Ethernet too?
    I'm using Cat 6 thinking it was the fastest. But I'm wondering if these cheap Cat 6 cables can be as good as the more expensive ones?
    Thanks
    Steven

    I've had bad luck on my own with ethernet cables, just once, with customers several times.  My ethernet cable I got from Comcast in the early days of Cable internet was so thick it could not be pulled out of the Powermac 7200/75's port without a pliers (sp?).  Of course this nearly broke the port once I managed to get it out.  Make sure if you get one with transparent ends, that all the colored wires that are supposed to be there are.  If you have any really old equipment, knowing the difference between a crossover and non-crossover ethernet cable is important.
    Edit: Lastly, with many older cables, the ends can come loose, or the tab that snaps it into place can break off.  So be careful.

  • AP Cable length issues - Will PoE injectors act as a repeater?

    Hello,
    We have a site utilizing the Catalyst 3650 switches with integrated controllers for WiFi.  Unfortunately due to a union/political situation we're not able to work closely with cable designers and installers to ensure cable length restrictions aren't exceeded and often have to get creative with remediation for such problems.
    I have 5x3700 APs that are hung in an extremely high ceiling with directional antennas that just can't boot up and connect to the integrated controller from the nearest closet.  The cable length is likely close to 200m.  Unfortunately, installing a 3650 closer to the APs is not an option due to architectural and environmental factors.
    I'm wondering if a power injector(AIR-PWRINJ5=) will act as a simple repeater bump in the wire and effectively extend the possible cable length if inserted half way between the AP and the Switch?
    We've tried using the 3560C compact switches for this problem which works great for WLC based installations but breaks the integrated controller scenario as all APs must be connected directly to the switch for the integrated controllers to work.
    Thanks,
    Greg

    You can try to introduce a power injector between the switch and the AP, at less than 100 meters from the A . You´ll guarantee the AP receives PoE correctly. However , the cable distance facing the 802.3 Ethernet protocol remains of 200 meters , and this will , if that works, that there are many collisions in the medium due to the timing of the ethernet protocol.
    If is possible, you can enter a small switch between the 3650 and the AP, as transceiver "copper-to-copper", without vlans , no routing, nothing ... just making functions of "repeater". Even there are catalyst switches of the Compact series, with inline-outline power (2960CPD-8PT-L,...). They could receive PoE of the 3650 and gives PoE to the AP, without aditional electrical wire.

  • Infinty in Kitchen - Hub in Study - ethernet cable...

    Infinity is being installed on 8 May.  The master socket is in the kitchen - the line comes in that way.  My study, where all the comms and PC stuff is is next door, so 10 metres of cable can easily connect them - big cellar below.  If I put in a length of Cat5 cable between the two rooms, will the engineer use that - modem in kitchen, Hub in study, or do I rehash that when he has gone?  Just ordinary ethernet cable or something special - with usual plugs on each end?
    Our TV is a long way off upstairs and I can connect to it via Homeplugs - if I were to get Youview would that work?
    Geoff

    If the modem in the kitchen near the current master works for you, which you say it does, that sounds the best solution.  You are always going to have more loss with extra on the VDSL path rather than the ethernet path.
    The main thing for the installer is changing the master or its faceplate, and installing the modem near to it.  He'll show you things with the HomeHub and your computer plugged in.  No need for that, but it does help confirm it is all working.
    If you have a convenient laptop you can bring to the kitchen, I would get him to install it and put the HomeHub near the modem and do the demo test with the laptop.  When it is all established that works and he goes, move the HomeHub to the study via your new ethernet cable.  
    Disconnecting and doing things with the HomeHub is fine.  Try to leave the modem connection to the master as is and do not do anything to the modem (other than change the ethernet cable to LAN1), as that can upset DLM.
    ~~~
    Wireless might just do streamed video (if your TV can use wireless anyway).
    Homeplugs should certainly work unless you are very unlucky with the mains.
    You need 500Mbps ones to get the most out of Infinity.  200Mbps ones should be more than enough for streamed video.  The actual speed you get from Homplugs is always way below the rated speed.
    I found (after reading another post on this forum) that using Homeplug in a twin socket with computer equipment in the other half of the twin significantly degrades performance.  Try never to use them on an extension, and certainly not on a power surge extension.
