Gigabit network slower than wireless

Antihero · 3 Jul 2008 at 15:51

Hi,

I have recently upgraded my wired network from 10/100 to Gigabit and now my network is painfully slow.

I've installed a Netgear 5 port Gigabit switch and CAT6 cabling but whe transfering files to my NAS drive the max speed I get is 5MBps!!!!

Also when browsing or downloading I get around 50 - 60Kbps if I remove the cable and turn the wireless on the laptop on I get a steady 270Kbps.

The laptop is a HP DV9820ea with Vista Premium SP1, I have tried all suggested fix's so far like disabling the autotuning, removing IPV6, disabling all firewall and antivirus software and turning off aero and the sidebar but still no change.

Any ideas or suggestions are greatly appreciated.

Cheers.

whats the layout?
PC - Switch - Router - Internet or PC - Switch - Cat 5e - Router Internet? could be anything. I'd guess interfearnce from a shoddy PSU on some hardware (TV?)

Sorry should have been a bit more specific.

I have a Netgear DG834GT router thats connected to a Netgear GS105 switch via a CAT 5e cable, connected to the switch is a Netgear Readynas Duo, PS3 and the laptop. Everything connected to the switch is fed through CAT 6 cables.

I have tried removing the router from the network so it's only the laptop and NAS drive connected through the switch but still no different.

laptop and NAS gigabit?

Yep both Gigabit, laptop has the latest drivers and the NAS has the latest frimware.

Windows registers the connection as 1.0Gbps and the NAS shows 1000Mbps.

what about direct from NAS to PC (ie one cable)

Download the Windows Network Monitor for Vista and check for CRC errors.

Exactly the same.

I was hoping this would help pinpoint the cause of the issue but every time I run the program it crashes.

Ok finally got Netmon working after some tinkering, but how do I check for CRC's I can't see a filter for it?

if direct link to the NAS doesn't work I'd be guessing your controlers damaged, RMA it!

When you installed the cat6 cabling did you have to do any tight bends on the cable, cat6 from what I've read can be very intolerant to tight twists and bends.

Also try a cat5e cable from the laptop to the NAS and see if the performance goes up. Not too sure how good the Netgear is but my Lacie minidisk and bigdisk NAS drives on 100mbs cabling/connection only averages around 7mb transfer rates which according to what I've read is really all the device is capable of.
