[SOLVED] Moving from 10/100 to 10/1000

[Sirius B]

Hi Guys. Even though I have a home network of 4 systems + Server, I'm no networking guru. Last weekend, a new (3 months old) 500gb hd brought down my server. All a.o.k. now but decided to clean up all the cabling & realised that all 5 systems have gigabit onboard nic's.

Connected up & all systems on lan shows 1.0 gbs speed - thought great then tried accessing the net - all rigs lost net connection.

Server + 3 upstairs with an Eidemax 8 port gigabit switch with 1 cable (thru switch) linked directly to Netgear WRG614 Router downstairs.

Server has 1 port NForce 4 gigabit nic - Workstation has Marvell 88E1116 PHY dual gigabit nic's - Desktop has Realtek RTL8100c 10/100 & Marvell 88E1111 gigabit nic's.

On reconnecting server direct to router & other 3 rigs to switch, they all get net access.

I have a niggling suspicion that I'm connecting the gigabit wrong!

Any ideas?

You may need to ensure that you have proper good quality Gigabyte cables

These are not just your normal 4 wire 100MB cables ( Tx+, Tx-, Rx+ & Rx-) running at higher speed, but 8 wire cables that must be connected in the proper manner .. not sure whether they are also shielded or not ..

I reckon this should be your starting point ..

Another thing that has puzzled me for a l9ong time too is the possibility of running a gigabyte link that cannot be supported by the motherboard speed .. a bit like having a Porsche and throwing a trailer on the back .. but that may well be just be me wondering out loud ..

Thanks, all cable cat6. When connected on all gigabit nic's, lan ok & everyone sees everyone else at 1.0 gbs. Unfortunately no net access on any rig except the one downstairs with the router.

As stated, I think I'm missing a connection somewhere but can't think where!

[Done_Fishin]

What exactly is your LAN config ...

Line >>>> Router >>>> switch >>>> PC's ?? or is there a split somewhere ??

Did you make sure you replaced straight cables with straight cables and any crossovers with another crossover ?

Remember if you connect a router with a PC directly it uses a crossover cable .. Router to switch is straight, switch to PC is straight .

[Sirius B]

Thanks Done Fishin. Come to think of it, I don't think I used a crossover, yet at 10/100, all rigs see each other as well as net access. When switching to gigabit, all rigs see each other but no net access. Will get a crossover cable tomorrow & try it.

10/100 layout..
Modem - Router Gnd floor
Router - Wife's Desktop gnd floor (Vista Business)
Router - 4 port Belkin 10/100 switch (for customer rigs) gnd floor
Router - Server 1st floor (2003/WHS)
Router - Switch 1st floor (Eidemax 8 port gigabit)
Switch - workstation 1st floor (Vista Business)
Switch - desktop 1st floor (Xp Pro SP3)
switch - Laser printer 1st floor
switch - NAS 1st floor

gigabit layout - as above except Switch - Server. On this layout, all rigs see 1.0 gbs network speed but no net access. If it's a case of needing a crossover, I then cannot understand how 10/100 layout works perfectly.

Again, I think I'm missing something here, but don't know what! Maybe a crossover will work?

[Done_Fishin]

Router to router will require a crossover .. a router is like a PC .. so would normally require a crossover cable unless of course it's one of those intelligent jobs that figures out connections for itself .. however whilst that might work with 4 wire not sure about 8 wire .. may not have ability to auto connect.

I can't tell from your statement what the set up is ... only what equipment you have and the immediate connections but since you say that everything is working on 10/100 ..
perhaps you have a duff cable .. or if you made them yourself (I make my own 100MB cables) maybe one of the wires "moved" .. as they always do when you're not watching has happened to me so often in spite of double / triple checking the colouring before crimping ..

I think that this is how the cabling should be handled

Router - Wife's Desktop gnd floor (Vista Business)

Straight Cable

Router - 4 port Belkin 10/100 switch (for customer rigs) gnd floor

Straight Cable

Router - Server 1st floor (2003/WHS)

Crossover
It might work with a straight cable if in 10/100MB mode it has autosense capabilities

Router - Switch 1st floor (Eidemax 8 port gigabit)

Straight Cable

Switch - workstation 1st floor (Vista Business)

Straight Cable

Switch - desktop 1st floor (Xp Pro SP3)

Straight Cable

switch - Laser printer 1st floor

Straight Cable

switch - NAS 1st floor

Straight Cable

Thanks Done Fishin. I'll see if I can get hold of a 15m crossover cable & see if that solves the problem.

Actual Equipment is 1x Netgear WRG614 4 port Router, 1x Belkin 4 port 10/100 switch & 1x Eidemax 8 port gigabit switch.

Modem & Router on ground floor due to the cable modem. 1x cat5e going from router to Belkin 10/110 in Workshop.

1x Cat6 going direct to Server on 1st floor (15m cable).
1x Cat6 going to Switch on 1st floor (15m cable).
Rigs & printers/NAS on switch 1st floor.

If crossover solves problem, It'll be one 15m cable less & will leave a spare port available on ground floor.

Cabling is expensive here in the sticks, so if cable too expensive, will wait until next trip to London, hopefully before the end of the month. will post result.

[Done_Fishin]

only other alternative would be to try to make a small adapter with a short length of cable made up as crossover

a back to back RJ45 that will accept the existing straight cable and teh new cable

mount one end of your crossover so that it mates with the correct pins on the existing straight cable (on the adapter I built using a bit of old board and some solder on connections I needed to mount the RJ45 backwards in order to mate up the pins correctly) then build the other end of the cable normally .. this got me out of a tuight spot in my apartment when I needed to extend an existing cable from a bedroom into my kitchen .. and it was pluggable so I could remove it and replace it at will

you however will be looking to see if you get a connection before rushing down to the sticks .. or you could once proven that it's the problem order one to be sent to you ..

Thanks Done Fishin. Will try that. PC World wants £40 for a cable & I'm not paying that.

I go down to London once a month to see suppliers (I'm a local system builder), next trip is due 23rd. If adapter don't work I'll try & get a cable there.

Started thinking after your last post - On a temporarly basis, would having the server on the ground floor near the router work & at the same time get a standard crossover?

[joshuaheard]

If you are forcing 1Gbps, it won't read the 10/100 switch. If that switch is between your lan and the internet, that is your problem. Get rid of any 10/100 gear and reconfigure your lan. I bet that fixes it.

you could try pushing it back to 10/100 .. just for that link using the old cable but I have no practical experience with your routers & switches so I don't know whether it will accept it ..

In theory it's no different to having a 10MB link to the ISP and 100MB connections to your LAN .. but as everyone, including Murphy, knows there is a world of difference between theory and reality

Can I see this for machine that connects and for one that doesn't?

Hold the Windows key and press R, then type CMD to open a command prompt:

In the command prompt window that opens, type type the following command:

Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

IPCONFIG /ALL

Right click in the command window and choose Select All, then hit Enter.
Paste the results in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Thanks guys for all the help. Done Fishin, your diagram helped solve the problem. It was a connection problem.

Just fiished re-arranging cabling & it works. 1.0gbs across network & also net access.

Shut down network & took all cables out. Started with router - connected modem to wan socket. THEN got 15m cable & connected to PORT 1 on router to PORT 1 on gigabit switch.

Put Server on Port 2 of switch, then worskstation, then desktop.

Plugged wife's machine into port 2 of router. Wife's machine is 10/100 but going to put gigabit nic in. For the rigs upstairs to see wife's machine, will need a gigabit router, brother suggested D-Link as that's what he uses & has had no problems with it.

Only problem left is that desktop cannot see net or lan - I know what the problem is here. It has 2 onboard nic's, 1 Realtek 10/100 & 1 Marvell 88e1111 gigabit. Have installed driver but XP Pro still doesn't see it. Uninstalled Realtek through device manager & rebooted, it still found the Realtek, so will have to rtfm for mobo &/or go to Marvell's site for updated driver/info.

Asides from that, server & workstation is working at 1.0gbs & both can access the net.

Workstation

Having a little problem pasting over for non working rig. However, I'm pretty sure that's down to a driver problem.

[Done_Fishin]

if these devices are supposed to be working they are working in IPV6 mode which doesn't always work on IPV4 systems .. plus .. due to conversion problems to IPV4 they tend to be extremely slow

No they not supposed to be working, don't know why they came up.

Couldn't get any joy from Marvell, so went to NVidia - an NForce4 chipset update was available. Installed & desktop now working at 1.0gbs.

All that's required now is to get a gigabit router.

Thanks for all the help guys. Very much appreciated.

@Done Fishin, will need a crossover to attach another switch, so again, thanks for the help.

PS: sorry to look ignorant - how does one mark post as solved?

[Done_Fishin]

Those Teredo devices must be wireless and are probably unused channels on your wireless router .. but I am only guessing about that ...
Nice to see that you are progressing with your setup ..

regarding cabling remember

similar equipment, when joined together, requires a crossover cable
dissimilar equipment, when joined together, requires a straight cable

Group 1
PC's, Servers & Routers are similar equipment and should connect to each other using crossover cables
Group 2
Switches, Hubs & repeaters are similar equipment and should connect to each other using crossover cables

Group 1 and Group 2 equipments are dissimilar and should connect to each other using straight cables

Thanks Done Fishin. those unused channels are more than likely wireless - I have it disabled.

Again, thanks for the help.
