Odd ethernet connection issue


Chancer

Recommended Posts

Hi,

I have a hard wired LAN.

My main PC has an Asus motherboard with an integral Intel 82579V Gigabit Ethernet port.

It connects to a Netgear managed hub. The hub connects to the router.

All works well.

Due to some broadband issues I have been sent a new router, a Sky SR102.

As part of the testing I disconnected everything and connected the PC directly to the hub. I couldn't get a connection - no LEDs!

I have tested the cable and swapped it out for another - still the same.

I connected my laptop using the same cable and it works fine.

If I connect to my old router - it connects.

Any thoughts?

@Chancer..Did you get this resolved???

Not knowing the brand of the modem / router you are replacing. There may be a difference as the 4 ports on the SKY SR102 only work at 100Mbps. Saying that the switch that you connect it to should negotiate / adjust traffic to & from the router & computers OK.

Assuming that your 1Gigabit network adapter's speed / duplex is set to Auto Negotiate.....NIC adapter properties / Configure / Advanced / Speed & Duplex...All should function correctly.

As long as your NIC settings are correct & set to auto, try connecting directly to the modem / router. You may wish to auto diagnose / repair / reset your computers NIC if the SKY router has a different internal IP address.

Another option would be to slot in a generic gigabit PCI network card & test as these are as cheap as chips.

Hope you achieve a successful result..

Not resolved.

I previously used two routers, a Thomson supplied by O2 and a Draytek Vigor which is mine.

I don't think it is about connection speed, and the network switch, a netgear, does negotiate.

Whatever cable I use the LEDs on both the PC and the router do not light up indicating no physical connection - and nothing connects. Plug my laptop in and they light up. It is strange.

I have had such poor service from Sky I am now awaiting my MAC code - so this will become academic!

It could be that the Ethernet port or network card on the PC is damaged. Have you tried replacing it?

You could also try pinging the router to see if packets are successfully sent. Then you can be assured is there's a problem with the pc or router

In most case scenarios this indicates that although a cable is connected, the parties are unable to hand shake correctly with each other & the symptoms often resolved by the suggestions I previously posted.

Well strange..Hope you get it sorted.

Have you changed some Services? In the past I used to tweak Services a lot and I got this same connection issue like you have.

Open Services.msc and then follow these:

Make sure these are set to Automatic:

Network Location Awareness

Network Store Interface Service

WWAN AutoConfig

Then these set to Manual:

Network Connections

Network List Service

Then restart your computer.

And sometimes CCleaner might mess up your router settings, it did that for me in the past quite a lot. My suggestion is that if you have a wired lan connection beware which items you check in CCleaner before cleaning.

In my case CCleaner caused router not to stay online, there was just blinking lan light on my router nothing else, but when I did a clean install and reverted my router settings back to default internet connection was working again.

But now when I have Mobile Broadband 4G connection I don't have this issue. This "usb stick" which gives me internet connection is also a modem.

Can you try wlan connection? Is it possible to get your router in wlan state?

Maybe worth reverting back to the original NIC drivers, I have a similar issue where if I update my realtech NIC via M$, even though it's an update for my particular NIC card, after reboot it doesn't work, so I reverted back to the one prior (stock nic drivers), and all works fine (I've had to block the update from the M$ updates)

Other than that I would be lead to believe it's a faulty NIC socket you have on the MOBO, it maybe worth seeing if you can put an PCI LAN card in and see if that works.

Thanks for all the comments.

My problem is, as stated, the PC connects fine when through the switch. The problem only appears if I plug into the router and not the switch!

Its also fine when plugged into other routers - its just the Sky hub.

@Chancer.. As i have been assuming that your NIC driver is up to date & still no go.

You may wish to read this & if possible with the issue you are getting, go for another option as the revues for the SKY SR102 are unfortunately not the best.

Should this not be possible, you are left with either connecting that PC through your switch to the modem or trying another NIC

People don't realise because everything runs off the back of BT even if your Sky a report of a fault gets passed from Sky to BT goes to the bottom of the pile and if your lucky four or five days later MIGHT get sorted if it's a BT fault 24 - 48 hours and its sorted,

Edit to say OK Yes BT is dearer but the service is better

A thought occurred to me as I was sitting in the Loo (Place where sometimes I have flashes of brilliance hehehehehh) I am wondering if the lead your using is a Crossover as opposed to a straight though?

If you are going BT they should be sending you a BT Hub 5 (LOVELY bit of kit) with it will be 1 RJ45 lead use that first to the Hub then put it between your Computer and your hub trying each of the leads you have NOW between the computer and the switch if one does not work its probably a cross over or simply a faulty lead.

If you want Patch leads they are dirt cheap on Ebay, I would offer to make you one to length but time I make it up and post it the ready made ones on ebay are cheaper.
