targeting 1GB intternal network

abdullah · 2014-08-11 19:02:32

Hello, what I'm trying to do is to establish a 1Gb local network, I managed to hint for 100 Mb, the story is below.

I got 1 PC and 1 Laptop, The PC is connectd to a network extender ( this one : http://www.linksys.com/en-eu/products/r … ers/RE2000 ) and the main router ( this one: EA6900 http://www.linksys.com/en-eu/products/routers/EA6900 ).

When the PC is connected to the extender by cable, I can download a file from the laptop at 100 Mb ( ~ 10 MB ), so I though I want the gigabit connection, but when I connect the PC directly to the router, I only get ~ 700 KB. Any guess what is the problem ?
I got a gigabit motherboard, ASUS z97.

Do either of those products support gigalan (too lazy to view). Does your motherboard? In my experience, netctl connects at the max rate automatically.

% dmesg | grep -i eno1

The RE2000 is not Gigabit. The specs page says 10/100.

I suggest you take a look at the extenders specifications (spoiler, the ethernet port is 10/100). I think your network preforms quite well if you get to 100Mb.

EDIT: I'm not quick enough writing posts here, it seems...

Errr... WRONG!.

The DESKTOP is connected to the Extender "RE2000" by ethernet, which when I transfer a file from that desktop I get A 100Mb connection!.

Now, The DESKTOP is connected to the MAIN router By ethernet, I only get 10Mb!.

that is the scenario,
MAIN-ROUTER ---> Wireless, Extender ---> Cable, Desktop. Result: 100 Mb connection.
MAIN-ROUTER ---> Cable, Desktop. : Result 10 Mb connection.

The MAIN-ROUTER is an Gigabit router.
The Extender is an 100 Mb.

I want that gigabit network, since 100 Mb is... slow (for internal network).

How is your laptop connected to all of this, wired or wireless?

How are you transferring files between the machines and how are you measuring the transfer speed?

I'm sorry, I was not able to filter that from your first post (700KB threw me off, I guess. Do you mean bit or byte?). Anyway, what I meant is that your final goal is not attainable with your current hardware. At least, if your goal is gigabit, you'll need wired connections to your laptop and desktop from the gigabit router. Current wireless technologies for consumers are just not that fast.

Other than that, as slitery asked: How is your laptop connected? If the laptop is wireless, did you test from the exact same spot with the same surroundings? Also, how many times did you test and what were the computers during the transfer?

Probably a hardware problem with one or more of (1) cable, (2) port on router, (3) port on motherboard. I've had bad experiences with - and thus have a low opinion of - 'consumer grade' gigabit hardware.

oh no sorry, I included the laptop at first since when I move away from the extender I get lower speed, like 3 rooms, when I stuck the laptop to the extender I get the 100 Mb.

@ runical, KB = Kilo Byte. Kb = Kilo bit. Byte = 8 bits.
MB = Mega Byte, which you never sees in advs, you see the Mb= Mega bit.

I measure by transferring a file !, I did test several protocols, ftp and http.

@ alphaniner, I got diffrent devices, and diffrent router ( Linksys EA3500 ) same results !.
I'm in doubt that it is from the consumer grade hardware.

has any of you manged to get that Gb network ?

Believe me, I know, but for some reason I expect people to be consistent with units. Ah well, might have been a stupid question on my part (as 700 KB is way slower than 10MB or 100Mb)

Anyway, what I suggest you do is first test a direct cable between your laptop and PC. Check if you can obtain gigabit this way. Also check if the cables are good.

After you have done that, start testing all of the ports on the router by connecting the PC and laptop to 2 ports at a time. Make sure you test all possible combinations. If the connection is slow on all combinations, I'd say your router is defective. If it is slow on one port, the port is defective. If it works, a miracle happened and you should be able to get a good network after that.

This of course assumes that these are all of the moving parts in the network and that all of them are gigabit capable.

EDIT: More clear formulation:

Test a direct connection between laptop and PC
1. Gigabit? Good, continue to 2
2. Not gigabit? Test cables and computers
Test all possible combinations of ports on the router
1. Some porsts slow? Defective ports
2. All ports slow? Defective router
3. All in order? No idea, it should work

This makes me suspect that it might be the cable that is slowing it down, to be honest. Try the direct connection thing with multiple devices and multiple cables.

Try running

ethtool etho

Which will tell you the capabilities of the port on each side of the cable as well as the actual link speed. For example on one of my machines I see the following

$ ethtool eth0
Settings for eth0:
        Supported ports: [ TP ]
        Supported link modes:   10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Half 1000baseT/Full 
        Supported pause frame use: No
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half 10baseT/Full 
                                100baseT/Half 100baseT/Full 
                                1000baseT/Half 1000baseT/Full 
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: Yes
        Link partner advertised link modes:  10baseT/Half 10baseT/Full 
                                             100baseT/Half 100baseT/Full 
        Link partner advertised pause frame use: Symmetric
        Link partner advertised auto-negotiation: Yes
        Speed: 100Mb/s
        Duplex: Full
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: internal
        Auto-negotiation: on
        MDI-X: off
Cannot get wake-on-lan settings: Operation not permitted
        Current message level: 0x000000ff (255)
                               drv probe link timer ifdown ifup rx_err tx_err
        Link detected: yes

If both sides of the link support 1000Mb but the connection is only 100Mb then try a different cable.

Yep! got the 1000Mpbs, ~ 112 MB, it feels so good, thanks guys, the proplem was not from the cable that is connected to the main Desktop, it was cos of other parts of the network.
