Shared internet speed problem

[Countryman]

I?ve suddenly got a strange problem. I have a desktop running Vista Home 64 and a laptop running W2K Sp4 connected to the internet via an SMC7404WBRA ADSL Barricade. The laptop is used to download (legal) torrents and saves the files to the ?Public? folder on the desktop.

In the past I have been able to surf whilst downloading. Now, the desktop is unusable for surfing if the laptop is downloading. With the laptop connected but not downloading, Visualware?s ?Test My Connection? gives a download speed of 1.03MBPS with a QOS of 99% on the desktop machine. When I set the laptop downloading the desktop machine reduces to 40.5KBPS with a QOS of 5%. The laptop is registering a download speed of 28KB in Azureus. Both machines have their NICs set to ?Auto-negotiation?. The only thing that has changed recently is that Windows Update has updated the Realtek driver.

Do you think that the Router is the villain?

Cheers.

Most likely your router is overloading, or you have your QoS roles reversed. Make sure that your torrent computer is set to Bulk so that it only gets whatever is left, and your desktop gets high priority setting so that it gets whatever it needs when it needs it. Another possibilty is that your router is overloading. Try limiting Azureus's connections to 50-150, and see if that helps.

It's also possible you are maxing out your upload capacity. Since tcp transmitions require an ACK to be sent for every packed received swamping the upload can greatly delay the ack response and end up slowing down your download speed even tho it's no where near maxed out. Try limiting the max upload in azuerus on the laptop to something 10-15kbs below your max upload.

And this.

Seconded.

Thanks for your thoughts guys. I too have come to the conclusion that it is my router. I already have Azureus set to 50 connections and a max upload speed of 30Kbs.

As I am about to move into a new house with CAT6 I need a new router anyway and was thinking about a D-Link DSL-2540B ADSL2/2+ Modem with 4-Port Ethernet Router and D-Link DGS-2208 10/100/1000 Mbps Gigabit Switch. (Thought I needed an ADSL modem and an 8 port router - seems from the D-Link site that a router is only a router when it has a modem in it. Confused!) I could go with just the 8 port router/switch and the France Telecom/Orange Livebox. However, the latter is notoriously unreliable so it is worth shelling out for a modem IMHO.

Cheers.

Just get a Standalone modem and standalone router. Put the modem in bridge mode and let the router handle the PPPoE.

I would stay away from low end d-link routers. I use one of their ethernet switches and it works fine but I've had bad performance from every d-link router I've ever tried hence I use linksys routers.
