Superhub Ethernet ports don't auto negotiate to 1Gbit correctly [Archive]

Hi.

Got a new PC at end of 2011, which has a GBE onboard NIC, which kept failing to auto negotiate to 1Gbit and hence refused to connect. Read that this is a known fault with the onboard NIC (Realtek GBE).

Bought an Intel Pro/1000 PCI-e Gbit NIC, which did sometimes connect at 1Gbit.

This proved to me that the SuperHub was therefore not auto negotiating to 1Gbit sppeds on it's ethernet ports.

I have since put the SuperHub into Modem Only mode and connected my Linksys WRT160N router.

The Intel NIC now correctly auto negotuates with the Linksys and so sets itself to 100Mbit, which is maximum supported speed on the Linksys' ethernet ports.

Wonder when the SuperHub's 1Gbit ethernet ports are going to work correctly at 1Gbit.

This has also happened to two of my firend's superhubs, and hence they had to go to same setup.

It works fine every time on my NVIDIA nic and my Iomega NAS which I believe has a Realtek nic in it. Are you sure you are using working cat 5e or cat 6 Ethernet cables?

dbateman2k5

10-01-2012, 04:53

Yes. I'm using a brand new 5m Cat5e cable between the router and PC.

Working fine at 1 Gbit everytime from my Broadcom Corporation NC7770 Gigabit card in my clearOS router to my Shub using cat 6 cables.

try cat6 altohugh cat5e does work at gbit there has been known issues for it not heard of issue with cat6 since it designed for gbit and 10gbit

Cat6 is not designed for 10gbit.

1Gbit is designed to work fine on cat 5, let alone 5e.

10-01-2012, 09:40

To clarify, you can run 10GbaseT over cat 6 for short distances, but you should use Cat6A cabling for normal runs.

Can, but it wasn't "designed for" ;)

Kymmy

10-01-2012, 09:45

Can I suggest trying a shorter patch cable to just confirm yes/no as to a cable problem.. Although the 5m cable might be cat5e that doesn't mean it's a perfect cable and might have problems. Either way it'll point you more in the right direction.

qasdfdsaq

10-01-2012, 09:47

Was going to say myself - a lot of cheapo cable claiming to be 5e isn't, and has problems with Gbe over longer runs - though didn't mention it as I rarely see problems at the ~5m level, more often at 20-50m. Still worth a shot.

Of the many problems I've heard about the Superhub having, the Gbe ports one isn't one I see mentioned often...

Kymmy

10-01-2012, 09:49

As you know it only takes a poorly crimped RJ45 or a cable that has been bent round to small a radius for it to mess up the signal capability

Andrewcrawford23

10-01-2012, 09:58

cat5 wasnt designed for gbit either :s but you can run it, the OP is having problem with auto negetioted the cheapist and most obvious option is replace the cable witha cable designed for that spec, 5e wasnt really designed for gbit either, and considering most people wont have cable lenght that long saying for 10gbit isnt incorrect it can happily run it but point me to commerical available 10gbit adapters that are cheap neough ie under £500 then might havea point or not meantion it but was only pointing out cat6 has far higher capicty

Possibly dodgy contacts? I used a short patch cable I grabbed out of a box of the things and was scratching my head mightily as to why it only ran 100Mbps. Then I looked closer at the patch lead - it was 4 wires only - probably some piece of tat that came with an ADSL router.

A single wire failure (crimp contact or break) will probably see you back on 100Mbps. If it's an intermittent fault it might work just fine on the next router/NIC pair you try. Simplest option is to repeat the testing with a different cable and by elimination determine whether it's the cable NIC or Superhub to blame. I can say that my Superhub switch worked fine at gigabit speeds - unfortunately if you ran it on fast WiFi for any length of time it borked it (pre R30).

Andrewcrawford23

10-01-2012, 11:57

I've seen similar problems with some netgear gigabit switches. Often solved by simply unplugging the cable from one port and connecting to another. Dunno why?

Another thing to try is seeing whether you can manually set the conection speed, in the network card's properties, rather than auto-negotiation.

although i do that it isnt advised esicallpy for non epert user, because if ther eissue then generally that is wher ehte problem will lie, i mean slow speed,s packet lost, high ping, because if it auto negetion to 100mb there a reason it doing it usually because of itnerference meaning gbit can tbe achived

99% of the time it is hte cable esicpally if the problem is gigbit not auto negetion to gbit but to 100mb, whether the cable is broken, cable crimped wrongly etc i have no idea but tha tis generally teh first afault then next would b the ethernet adapter,

the biggest problem is for the op if it the only piece of hardware they have at gbit it will be hard to rule there comptuer or the superhub out if thecbale doenst fix it, but i also suggest to the op try all the ports witha brand new cable bought out the shops they generally onylas £1 fora few metres

I'll see if I can get a 2m Cat6 cable to test with (will try eBuyer or Novatech).

Don't need 5m but that is the shortest cable that Comet did.

ferretuk

10-01-2012, 21:43

You've already got a second cable to test with - Use the ethernet cable that you've got going from the SH to the Linksys router.

It's not going to be a length issue - I've got a 30m run of Cat5e for a 1Gbps link and it's fine.

For the distance you're talking about there's no practical difference. You're swapping cables around to prove if you have a faulty cable, not if you're exceeding the perfomance of a non-defective cable.

100BaseT uses two pairs of the four pair cable - 1000BaseT uses all four pairs

auto negotied if that is at fult will be hard to tell if it the cable if it cat5 cable since it does test on teh cable to determine speed

so since cat5 cant do gbit it will think oh set it to 100mbit so using cat5 wont say if it cable fault

Nonsense - No 'test' is performed on the cable. See:

http://en.wikipedia.org/wiki/Autonegotiation

Cat 5 cable *can* cope with 1000baseT for short distances and will provide an acceptable test for the OP without ordering more cables.

if you say so, (oh just cause wwikipedia says something doesnt make it right ;))

yeah cat5 can do it on very shot distance i say about 0.1m but hay i dnt knwo anything :D only been doign it for 15+ years :s worked with gigabit before it was even in public domain been workign with 40gbit recently oh wait that doesnt exist does it ;) well not in public domin yet

Already suggested a long time ago in this thread that he should try a short patch cable to rule out the devices ;)

A crappy crimp, a cable that's been bent to much or a bit of corrosion could cause any of the issues.

100Gbit is both public domain and operates in production networks.

Claiming 15 years of experience doesn't really wash when you are working on 1st line, on the phones, as an outsourced VM residential tech support agent.

Supporting customers whose cable connections have failed on the phone doesn't really count as working with VM's STM-256 ports.

If you genuinely did have 15+ years of experience, and I'd be impressed if you were working in commercial grade networking aged 15, you'd know that the difference between CAT5e and CAT5 relates to better insulation between the individual wires reducing crosstalk meaning that CAT5e is assured as being good for 1000base-T up to 100m.

In between mocking Wikipedia you may want to read it then you wouldn't be making stupid comments like gloating over 'working' with 40Gbit and claiming it doesn't exist in the public domain.

Curious then, that one guy would encounter three "faulty" Superhubs. Theoretically possible, but highly unlikely.

Yet, if it's not the cable, it's not the individual Superhub, and isn't the network card, what is it? Bad PC?

I have tried two NICs in this PC (the onboard (Realtek) NIC and the PCIe (Intel) NIC), and my laptop's NIC (can't remember make, possibly another Realtek)). Laptop is mainly used in WLS mode, but tried via ethernet just to test a different NIC.

Tried several 1m-2m Cat 5 cables I have (have a collection of them lol), tried 1 5m Cat 5e cable. Yet to buy and try a Cat 6 cable.

Realtek NIC - tried with driver that was already present, driver from Windows Update, and latest driver from Realtek.

Intel NIC - tried with driver that was installed as soon as Windows detected it, and latest driver from Intel.

On the bad PC note, this can't be as it's a brand new PC that I have used it's recovery mode twice!

I think it may be easier leaving things as they are with my current setup of...

Super Hub (Modem mode) > Router (Linksys) > Port 1 (PC), Port 3 (PS3), Port 4 (Printer), WLS (iPhone, Tablet, Laptop).

Nope, not to my knowledge.

If you've had to use recovery mode twice on a brand new PC that sounds like there's quite a lot wrong with it.

dbateman2k5

11-01-2012, 23:34

The reason I used recovery twice was...

1st time was because of me using PC Mover, which screwed up my system.
2nd time was due to the onboard NIC not going to 1Gbit correctly (recovery done on advise from Comet).

Nothing is wrong with the PC, which is operating normally, except for the auto negotiating to 1Gbit with the SuperHub.

Guess I'll get the Cat 6 cable to test with first, then maybe get a Linksys 1Gbit router if needed (as it looks like the only way I can find out if it's the SuperHub or not, is by trying another 1Gbit router).

Chrysalis

12-01-2012, 02:38

yeah cat5e should do the job assuming its not faulty.

I usually buy cat6 but only because its around the same price as cat5e so making cat5e a redundant option.

kwikbreaks

12-01-2012, 10:43

Do you crimp your own rj45s on? I recall reading that the thicker insulation used with cat6 makes it a bit of a bitch.

I did all my home networking using a 300ft roll of cat5e that came with some rj45s and a crimp tool for £9.99 delivered off eBay. I used wall sockets and ready made patch cables but have done a few crimps myself with varying degrees of success. Apart from one initial bad joint on a socket it's all worked just fine for a couple of years now.

My main network is based on a couple of gigabit switches (one upstairs and one downstairs) with a 100Mbps only router now just acting as DHCP server and internet gateway. I've only just bought a cheap TP-Link N AP as I only use WiFi for tablets and phones and in the main G on the router has been OK (beat the N on the Superhub for range easily).

When I had the Superhub I did hang a NAS off it and it ran at 1Gbps no problem as did the link into the switch. The VOIP phone adaptor is only 100Mbit anyway but that was fine too.

Nice setup dawg. I recently started crimping my own cables too, and if I wasn't renting I'd have wired it up structured style already too.

Kymmy

12-01-2012, 13:41

Always had an RJ11/12 and RJ45 crimp and yes you have to be careful when crimping.. When I worked in one of the repair centres I made up a little tester with many input and output sockets, a row of LEDs and a 8 pole rotary switch for dealing with cross-over/specialist cables, it would save time and confirm it all working. Though these days a simple multimeter does as a test or even dedicated testers are cheap enough.

Got a engineer booked for Monday 30th January as Tech Support did a Line Check on my SuperHub and noticed that the power levels are high. They said that this may of caused the ports to fail to negotiate correctly.

They said that the engineer will have a replacement SuperHub with them if I wish to replace it to see if issue persists. May ask engineer if they have a modem instead (no harm in asking), as I'm starting to dislike the SuperHub.

You need to bear in mind that Comet/Currys/PC World know nothing and you need to takle everything they say with a pin of salt. More often than not, their solution to fix every problem is to bang the recovery discs in and reimage the hdd.

Perhaps you have just been unlucky with a bad cat5e cable. Above you state you have tried several cat5 cables. I would not test with cat5 at all. Forget cat5. It won't do gigabit reliably. Gigabit = cat5e or cat6. Anyone telling you that a short cat5 cable should do it is adding confusion.

So basically you've tried ONE cat5e cable. It's probably a bad cable. I think you are over complicating it. It's unlikely to be the NIC yet you bought a replacment one before buying a new cable?

Test with a new cat5e or cat6 cable then come back and say it doesn't work. Also, to prove a cable can run at gigabit speeds link your laptop and PC up directly via it.

There's nothing wrong with the superhubs you are getting sent imo. You are VERY unlikely to get 3 bad ones that all exhibit this fault. Also the above is unlikely. Too high a power level will be very unlikely to affect the realiability of gigabit ports.

Cat5 cable is certified to carry gigabit reliably up to the maximum allowed length of an ethernet segment - 100 metres.

He didn't swap out SuperHub, saying that it's likely that doing so, I would still have the auto negotiating to 1Gbit issue.

He said he'll report the issue to get it looked at and said there is a firmware upgrade coming for the SuperHubs soon.

I've been unable to test with a Cat6 cable, as I haven't got one, and unable to get one till next week.

My experience of using cat5 cables is they often do not work at gigabit speeds. Yes they are certified I know. But it was borderline running 1000-baseT on cat5 hence the cat5e standard was introduced. I'm simply saying rather than getting into the technicalities and stubborness of "it should work on cat5 fine" wouldn't it be easier to recommend to the OP to simply buy a cat5e / cat6 cable to maximize the chance of it working for him, given the cost between them is nothing.

That's because your cat5 cables aren't cat5 cables. They're crappy imitations that barely meet cat4 spec.

Perpetuating myths and encouraging people to hand over more money to deceptive companies peddling faulty products and buying into the whole "bigger is better" shenanigans isn't going to do anyone any favours.

In the meantime perhaps I should start up a company that buys up bog standard cat5 cables and reselling them with a cat7 sticker on. And when 10gig doesn't work on them I'll just have to start peddling rebadged cat6A cables as Cat8.

Once again, crap cable is crap cable. All you're advocating is buying crap cable with a bigger number scribbled on it.

Oh I'm totally game for making do with just what will work. I hate/won't pay a premium for cables as much as the next guy. £30 HDMI Cable anyone? ;)
A lot of people think cat6 is required for gigabit speeds. I generally just stick to cat5e and tell most people to buy that since it's cheap/easily obtainable and always works. I have never, ever had a cat5e cable that did not do gigabit speeds including "crappy" cheap ones. Just saying.

Anyway OP hope you sort it out but I would agree it's unlikely to be your superhub at fault. Did you try wiring laptop to PC to test the speed you get direct?

dbateman2k5

30-01-2012, 17:53

Did you try wiring laptop to PC to test the speed you get direct?

Yep, and got 1Gbit connection between both (using the Cat5e cable I had). So that rules out a faulty NIC.

I will re-use this test when I get the Cat6 cable next week, then providing that works I will re-test using SuperHub-Cat6-PC.

If you used a cable directly between your PC and your laptop it's a crossover cable... You need a straight through cable.

If you used a 1Gig switch between them then you've ruled out the cables as well...

Perhaps we're starting to get to the bottom of the problem then.

A crossover is needed somewhere to get a Desktop <> Laptop connection to work. As you're testing used a straight cable one of the PCs must have the ability to determine if a swap is required and then switch. From what you've said (recently!) your laptop also has a gigabit port so:

Tests:

1. Plug the laptop into the SH - Confirm correct operation a 1Gbit. I haven't completely re-read the the thread but I'm not sure you've done this so far? My suspicion is that it will work...

2. Look at the PC NIC setting and try and find a setting to turn off auto crossover (may be call Auto MDIX). Once turned off, try the PC plugged directly into the laptop and confirm that you don't get a working connection.

3. Then try the PC in the SH again.

Remember that you have eliminated the cable (by using it between the PC and the laptop) so you can put any Cat5/5e/6 thoughts to bed!

It sounds to me that the SH port and the NIC are not correctly determining which end needs to switch...

dbateman2k5

31-01-2012, 13:34

It sounds to me that the SH port and the NIC are not correctly determining which end needs to switch...

I've never used a cross-over cable tho. All my cables are the standard straight cables.

I'm starting to think that the Auto MDIX setting may be what's be causing the fault. Is there a way to turn this off on the SuperHub side as well or is it only required on one end of the connection ?

1. Plug the laptop into the SH - Confirm correct operation a 1Gbit. I haven't completely re-read the the thread but I'm not sure you've done this so far? My suspicion is that it will work...

Will need to double check this, as I can't recall whether it did or not.

I think I am right in saying (please correct me if wrong someone) that the ports on the superhub should go orange if at 100mbps, and green if at 1000mbps. Just thought I would mention that to aid testing as a quick visual check. Everything I have ever plugged into the superhub including a PS3, goes green and auto negotiates with no issues at gigabit speeds.

Auto/auto failing to agree on the correct speed is far from uncommon. I have seen it hundreds of times in commercial environments - I remember for example there was a common problem between certain Intel NICs and a specific model of Cisco switch.

The solution is usually a simple matter of setting the port speed manually. Having said, does the superhub allow you to set each port speed and duplex manually?

Superhub doesn't even allow you to set DNS manually.

and things like that are the little things which we dont think of but make a huge difference. I gave up on Virgin DNS a couple of years ago and I don't know what I would do without google dns now. There have been several times where there has been a flurry of posts on the forum with users saying they cant get to a whole raft of sites because of problems with Virgin dns servers yet those of us using non-virgin dns have been absolutely fine.

I don't want to brag, I am only hoping to bring some sense and reason to those who are reading this thread and show that once again, the shub is not so super.

1. Plug the laptop into the SH - Confirm correct operation a 1Gbit.

Out of interest, what would be the best way of confirming correct operation at 1Gbit speed? I've noticed recently that the transfer speeds between my two machines both wired in to the superhub seem quite slow, like 3 - 4 MBps. I bought two Cat 6 cables thinking this might help but it hasn't. Am I right in thinking this is slow? I'm not an expert by any means!

Look at your connection status window. If it says 1Gbit it means it's connected at 1Gbit.

Thanks! For some reason I'd missed that and was expecting the answer to be something more elaborate. That's helped me identify that one of the cables was dodgy. I've swapped it for another one and bingo, super fast speeds. Cheers.

Seems I'm not the only one with the auto negotiate to 1Gbit issue with the SuperHub.

Someone replied to my post on the VM Support Forums, saying they had exactly the same issue and have emailed Netgear Support. Netgear told them it's be escalated to Level 2 Technical, for them to have a look at.

So it's definately looking to be a firmware and/or hardware fault with the SuperHub, that affects people with certain NICs and/or routers (depending on whether SuperHub is in modem mode or not).

I have also emailed Netgear, and am awaiting their reply.
