Help tracking down why my WIRED connection is SLOW

I just got the 3700 to replace a 3500, hoping it would fix the problem, it hasn't. The router is connected to an ActionTec DSL modem.

My WIRELESS Mac gets great speeds - about 1.3MB/s (my DSL connection is 1.5Mb/768Kb). If I try to download the same file from my PC, which is connected over GigE to the router, I get about .25Mb, consistently.

I don't think it's the router, since my PC used to be pretty fast. I'm hoping someone can give me some tips for tracking down why my PC is "slow". Specs are Windows 7 x64, 8GB, 2.6Gz Quad core, firewall is enabled (still slow if disabled), no trojans that I can find, etc. It's really odd. I can't even stream 720P YouTube videos on the PC without constant stalling, but they play fine on my Mac.

Aside from wiping my PC, is there a checklist or anything?

Re: Help tracking down why my WIRED connection is SLOW

I've had a few issues with certain devices not wanting to auto-negotiate correctly on this router. Try hard setting speed and duplex and see what that does.

One way you could verify a speed/duplex mismatch is with the ping command. You would see packet loss (which would be the cause of your "slowness").

Re: Help tracking down why my WIRED connection is SLOW

I just removed the router and plugged the PC directly into the modem and now I'm getting great speed - full 1080P streaming from Youtube, etc.

My ping times to google.com are 63ms, both through the router and straight to the modem.

So maybe it IS something going on with this (and the 3500) router. Since it USED to be fast, could my ISP have changed something to affect Windows 7 performance? Or maybe a recent OS update?

When you said to fiddle with duplex settings, where would I do that? I have an NVIDIA nForce networking controller.

Re: Help tracking down why my WIRED connection is SLOW

Anyone?

My feeling is this is some strange interaction between Windows 7 and/or my particular NIC and the router (if I take the router out of the equation all is fine).

Should I be contacting official Netgear support channels?

Re: Help tracking down why my WIRED connection is SLOW

Take a hard look at the router's configuration. Is the router using the ISP's DNS servers? Is the router configured as a DHCP server? Are your clients hard wired or wireless? If wireless, are you using the router's Access List via MAC address? Have you setup Reserved IP's using the correct MAC address?

These are just a few of the configuration issues that could affect your computer's performance. Taka a really hard look at DNS . . .

Re: Help tracking down why my WIRED connection is SLOW

I doubt it's DNS, since my timing tests were done on single large files, and wouldn't require multiple DNS lookups. And my wireless Mac doesn't have any performance issues at all going through the same router. Also, I'm getting over 1MB/sec from a Linux server also connected through the router.

It's something related to this Windows 7 machine and the router.

Re: Help tracking down why my WIRED connection is SLOW

Yeah, I had a Netgear 3500 the week before that (still have it), that had been working fine. The "problem" only manifested within the last 2-3 weeks. But the problem started, and thinking it was the router going, I got the 3700. And was surprised to experience the exact same problem.

So a couple of hours ago I go through all the router settings carefully. I see UPnP is turned on and my Windows machine is in the list below it. I turned off UPnP and immediately tried downloading a large file (a Linux ISO). I got over 1MB/sec! Then I tried one of those 1080P YouTube videos and it streamed perfectly.

Now, a few hours later, everything is slow again. I just tried a 1080P Youtube video and again it stalled and will not stream. Same thing plays perfectly on my wireless MacBook sitting right next to it. :-(

This is very frustrating!

I have taken a closer look at your IP Configuration and count no less than 3 class C networks (192.168.1.6, 192.168.154.1, 192.168.239.1). In order for your box to function properly routes must be setup via the NVIDIA adapter. Has this been done?

Routes are setup via the 'Advanced . . .' settings of the Internet Protocol Version 4 (TCP/IPv4) Properties sheet. I am not familiar with the MAC nor VMware, but I suspect your machine is configured as a router with a corrupt routing table . . .

If this is the case you will need a crash course in routing or disable/remove the VMware adapters . . .

Those were inactive VMWare virtual adapters. Just to check I uninstalled VMWare which also removed those adapters. Now I have just the 192.168.1.6 network. The problem remains.

Re: Help tracking down why my WIRED connection is SLOW

Have you checked the Link Speed and Duplex of your Local Area Connection's NIC (Network Interface Card)?

The default setting is 'Auto Detect' . . . set it to the fastest Link Speed your NIC can support, and Full Duplex: i.e. 100Mbps/Full Duplex -or- 1000Mbps/Full Duplex . . .

Navigate to:

Control Panel\Network and Internet\Network Connections . . .

Select you Local Area Conection by using the left mouse button . . . use the right mouse button to select 'Properties' . . . Click on the 'Configure' button . . . Select the 'Advance' tab . . . in the list of properties select 'Link Speed & Duplex' . . . use the drop down button to select the desired 'Value' . . .

You probably won't have to reboot, however, its always a good policy to reboot after a configuration change to ensure the change is written to the registry . . .

Re: Help tracking down why my WIRED connection is SLOW

Naturally, the above information is contingent upon all components of your network operating at the speed selected. i.e. The WNDR3700, with proper cabling, can support up to 1000Mbps. However, if your laptop's NIC supports Gb transmissions, but it's connected via a switch that maxes out at 100Mbps you are limited to what the switch can handle. This is refered to as a 'bottleneck'.

In this case you would choose 100Mbps/Full Duplex . . .

You shouldnt have two gateways listed... Only the router..
If the incorrect gateway is listed then packets are going to get lost or delayed while searching for a path.

There are several of these:

[DHCP IP: 192.168.1.6] to MAC address 00:1b:fc:8d:00:b7, Monday, October 25,2010 06:12:39

For that IP address, looks like there is one every 10-15 minutes or so. Normal?

Have you checked the Link Speed and Duplex of your Local Area Connection's NIC (Network Interface Card)?

The default setting is 'Auto Detect' . . . set it to the fastest Link Speed your NIC can support, and Full Duplex: i.e. 100Mbps/Full Duplex -or- 1000Mbps/Full Duplex . . .

Navigate to:

Control Panel\Network and Internet\Network Connections . . .

Select you Local Area Conection by using the left mouse button . . . use the right mouse button to select 'Properties' . . . Click on the 'Configure' button . . . Select the 'Advance' tab . . . in the list of properties select 'Link Speed & Duplex' . . . use the drop down button to select the desired 'Value' . . .

You probably won't have to reboot, however, its always a good policy to reboot after a configuration change to ensure the change is written to the registry . . .


The control panel shows the NIC connected at 1.0Gbps, and it is going through a Netgear 16 port GigE switch. Though I've had the same issue with the computer going directly to the GigE ports on the router itself.

Do you think changing it to 100Mbps Full Duplex would make any difference if it's already connected at 1.0 Gps? Also note all is fine when the computer is plugged directly into the modem (bypassing the router).

Re: Help tracking down why my WIRED connection is SLOW

the routing tables look fine (all of your other adapters have been removed...)

What is the "Location" Set to under windows...
It shouldnt make a hoot when it comes to internet browsing.
I think "Location" is based off of the MAC your connecting to, and some firewall rules may apply based on the device it detects.. So it will treat your modem and router differently. All of the IPv4 adapter settings are global for the wired device me thinks.

And when you do a "ipconfig /viewall" is it still listing 2 gateways?..

If it is then I would reset the ipv4 settings fully by going into a command prompt and typing
"netsh int ip reset resetlog.txt"
then rebooting the pc..

using the netsh command may fix the problem anyhow so you could give it a go.
