slow internet when wired to router

Hi

I am at my wits end with this problem and am desperately hoping someone here can help. I am running windows 7 home premium 64 bit on a new AMD Quad core system (AMD Athlon II x 4 630 processors). I have 4Gb of ram with a gigabyte motherboard and nvidia ethernet controller and Ralink wireless LAN card. I have been running the system for quite a few months now with no problems and then I had to move the computer to an area where the wireless signal was going to have a tough time getting through - this is where it all starts going pear shaped!!

I ran a network cable (along skirtings, through door frames etc.) from my Netgear DG843g(V4) router to the computer and connected it up - connected it to the internet and my network no problem, except that my speed to the intenet is now in the region of 150 - 350kbps. I have an 8Mbs broadband connection and through the wireless connection (before I moved the computer) I was getting anywhere between 3500 and 4500kbps. I have been able to eliminate the following;

• dodgy network lead - if I unplug it from the back of my computer and plug it into my laptop (running XP) I can connect to the internet at between 5000 and 6000kbps.
• Router (for reasons stated above).
• Homegroup issues (am not using the homegroup functionality)
• IPv6 (have never used this - it is not enabled)
• Drivers (network controller, router, motherboard etc. etc. - have spent ages ensuring these are the most up to date versions for my hardware).
• Firewall/Antivirus - I am using Zone Alarm and AVG and have turned them both off with no change to my connectivity.
• Conflict between wired and wireless network controllers (I disabled the wireless controller)

I have tried;

• starting in safe mode with networking - no difference
• shutting down all running processes via the task manager with no difference
• tweaking each setting on the network controller (speed/duplex settings etc.) - each time checking to see if there had been any change - there was none.
• installing Malwarebytes to see if that could identify any issues - it didn't
• Running the network troubleshooter - it just comes back and says that everything is fine and it couldn't find a problem!
• Disabled Autotuning (from a tip on the web) - no effect
• Removing RDC (another web tip) - no effect.

I have reverted to enabling my wirless connection again but this isn't a long term solution for me - does anyone please have any suggestions?

Thanks,

Nice Post thanks


Do us a favor and ping the routers IP. I would like to see the response time.

How long is the cable, cat 5e, or cat 6?

If you want to save time run an ipconfig /all and snapshot the output and upload.

Thanks for the response

The cable is Cat 5e and is about 10 metres long. I attach four screenshots - the ipconfig/all and the ping result for the desktop (the computer running windows7). I also did the same thing for the laptop by unplugging the cable from the desktop and then plugging it into the laptop just in case this would be of any assistance.

Thanks

I have a tip, uninstall zone alarm and AVG then renable IPv6 as there is no reason to disable it what so ever.

Both AVG and zone alarm are famous for causing problems like this "dropped packets".

The Argument against Disabling IPv6
It is unfortunate that some organizations disable IPv6 on their computers running Windows Vista or Windows Server 2008, where it is installed and enabled by default. Many disable IPv6-based on the assumption that they are not running any applications or services that use it. Others might disable it because of a misperception that having both IPv4 and IPv6 enabled effectively doubles their DNS and Web traffic. This is not true.
From Microsoft's perspective, IPv6 is a mandatory part of the Windows operating system and it is enabled and included in standard Windows service and application testing during the operating system development process. Because Windows was designed specifically with IPv6 present, Microsoft does not perform any testing to determine the effects of disabling IPv6. If IPv6 is disabled on Windows Vista, Windows Server 2008, or later versions, some components will not function. Moreover, applications that you might not think are using IPv6—such as Remote Assistance, HomeGroup, DirectAccess, and Windows Mail—could be.
Therefore, Microsoft recommends that you leave IPv6 enabled, even if you do not have an IPv6-enabled network, either native or tunneled. By leaving IPv6 enabled, you do not disable IPv6-only applications and services (for example, HomeGroup in Windows 7 and DirectAccess in Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can take advantage of IPv6-enhanced connectivity.

Thanks for the tip

But, I can't see how it could be either AVG, Zone Alarm or IPv6. I am running the exact same versions (of AVG and Zone Alarm) on my laptop and this doesn't suffer the same problem when connected to the network cable. Also, my desktop when it was connected wirelessly was still running the same versions of AVG and Zone Alarm (and had IPv6 disabled). As it happens my wireless signal has turned out to be a lot stronger than I thought it would be and when connecting via the wirelss adapter I am achieving internet speeds of between 5 and 6Mbs all with AVG, and Zone Alarm running and with IPv6 switched off.

I am still anxious to get the wired solution rectified as it should hugely improve my file transfer speeds over my network (and with any luck improve my internet speeds even more). And as much as anything, if something should work in a particular way then I would like it do so.

I appreciate the suggestion but I just cannot see how these programs are causing the problem for the reasons outlined above.

Thanks

Hi Ken

You said to PM you but I have looked in the user CP and don't seem to have this functionality - is it enabled on my account?

Thanks Mike but I don't seem to have this option when I left click (see screenshot) - is this perhaps because I am a new member (2 days).

Ukko your best bet is to contact John (z3r010) as he is the Administrator.

EXACT same problem!

I have the EXACT same problem! And it's driving me crazy!

I am using a Netgear Rangemax 3700 (but same problem with the 3500). When connected DIRECTLY to my modem, my Windows 7 x64 Home Premium machine gets about 13Mb down (I have a 15Mb/768Kb DSL connection).

When going through the router, I'm lucky if I get 256Kb down (upload speed doesnt't seem to be affected that much).

Interestingly, my MacBook Pro connected to the router WIRELESS is getting about 10Mb down!

ping to Google in both setups yields about 63ms.

Have you guys sorted out what the problem could be?

Here is my ipconfig:

Hi Stele

I could not find the answer in these forums. I have found the answer now but I'm not sure if it will apply to you. My solution was to go and buy a new PCI NIC (a cheap £5 job from novatech). Everything now works fine and as you would expect it to. I still don't understand exactly why this solution worked for me because I'm not entirely convinced it is as simple as a hardware fault on the NIC built into my motherboard - I still think it is software related but after months of trying everything I could possibly think of I thought it would be worthwhile forking out a fiver 'just in case'.

One thing to try though - can you connect up the MacBook Pro through the network cable to the router? - if this suffers the same slow downloads as your Win7 machine then it must surely point in the direction of the router. If the MacBook when connected via a cable doesn't suffer the same slow downloading then I think it might be worth you sticking a £5 NIC into a spare PCI slot and see what happens.

Good Luck - let me know when you manage to fix it

Thanks for the reply. I doubt it's my NIC, since I am getting full speed to the modem when I bypass the router.

The Mac plugged into the router without wireless also streams perfectly.

It's something Windows 7 specific, when going through the router.

You're right, I don't think it is your NIC, same as I don't think it is my motherboard NIC that was at fault, but until I can find the source of the software issue, the new NIC works for me

Sometimes certain brands of network cards have a hard time connecting to certain other brands of routers. The difficulty seems to be related to negotiating a protocol. This could be a difference in implementation of the standards.

As a shot in the dark, this issue sounds like a difference between full duplex and half duplex (NIC to Router) causing collisions... As a computer operator, we had to get into the habit of explicitly setting both NICs and Switches to full duplex instead of letting the components negotiate the protocol. I forget exactly how to do it, but a little searching may provide a methodology for your card and/or router to hardcode the connection parameters.
