PC refuses to sync at 1Gbps??

Hi folks,

Any thoughts on this one?

Mobo is an Asus P5B Deluxe WiFi/AP with dual onboard GB lan ports. With the latest drivers these sometimes sync at 1Gbps but after a reboot drop to 100Mbps. Forcing 1Gbps results in no network connectivity.

Bought a D-Link DGE-528T which when I first plugged it in connected at 1Gbps, now it refuses to connect at anything over 100Mbps.

What can be the problem? My Acer Revo always connects at 1Gbps as does my PS3. There's 2 netgear Gigabit switches on the network as well as an O2 router.

I'm not using DHCP for any of these.

OS is Win XP Pro SP3.

Getting a tad sick of it now :( Means very slow transfers between the server and PC.

Any thoughts on this?

Cheers!

Paul.
 
Oddly enough it never even occurred to me. I make my own cables but even with premade ones it's never worked consistently but I'll give it a go. Cheers!
 
Nope not the problem. Everything else going into the switch shows as 1Gbps.

Swapped cable last night and stayed at 1Gbps, in fact it had negotiated this before starting Windows. However this morning no joy, refuses to connect at anything beyond 1Gbps.

I really don't get it.
 
Tried right click on network icon on task bar-status-properties=advanced-speed and duplex ?
Try this on all pc`s and try setting to 1000
Worth a shot anyway :)
 
Already tried setting to 1000Mbps full duplex. The D-Link card actually sets itself as 100Mbps even when you try and force it.

I now have an Intel Pro/1000CT on the way to try a really good card.

I have noticed that Eset loads a driver against each network card as part of it's firewall but not sure if that's it or not.
 
Deffo worth disabling any firewalls etc. They often sit drivers ontop of the nic driver which could interfere.
It might also be worth just updating the driver.
I has some Dell Sx280s have very strange NIc issues when sync'd at 1Gbit. They'd report as sync'd but the sent packets would sky rocket at a rate far above what the NIC could do while not recieving anything. I reckoned this was a driver issue, probably McAfee enterprise's network driver. Newer Opti 160s or 755s work fine. Because I can't take virus scan off I actually ended up setting the switch ports to AUTO 100 FULL, which fixed it.
 
Well Eset have sent me their Safe Mode uninstaller as I'm having another issue anyways. Going to wait until my Intel NIC arrives.
 
Nope.

Cat5e will do 1Gbps just fine.

Have you tried in both Onboard NICs?

Yep, it's really odd. I've had one running at 1Gbps which is why I sold the Intel NIC but they stopped again.

Will see what happens with the Intel card and a complete reinstallation of ESS.

If it's WinXP being odd then maybe when I get Win 7 in October it'll work ;)
 
I'd usually recommend using a descrete premium Intel/broadcom NIC regardless if it's used for transferring files etc. They perform much better for sustained throughput scenarios.
 
whack in a linux live boot cd, and see what that connects at

could be a duff XP install..?

get latest drivers for the NIC website, not the board's site
 
Nothing wrong with the switch, all ports have been tested. Never thought about the live CDs....and I always go with the NIC manufacturers drivers from their website wherever possible.
 
Can you hard-configure the ports on the switch? auto-negotiation is flakey at best and I always hard code the settings where possible.

With the onboard Realtek forcing 1000Mbps stops the NIC being able to connect and says the cable is unplugged, D-Link just plain ignores it and connects at 100Mbps. Switch is unmanaged, managed switches just for home are rather expensive ;)

As I say I'll let people know how I get on with the Intel NIC which should be here for the weekend :)
