Well I spent an afternoon trying to get the setup right, and it's working, but not quite as it should.

I know that while my equipment isn't the best, I have all the necessary parts, and have no money to spend on new stuff right now.

I have a d-link 502t modem for my ADSL2+ connection at around 6meg down and 2 up.

Connected to that i have a WRT160N Linksys router. Then I have laptops connected to this router via wireless n usb adapters (the least favored out of wired and pci I know).

My problem is that I am suffering from low bittorrent speeds, and I'm pretty sure this is because the d link modem is also a router, and so I have two routers trying to route. I have done some reading about bridge mode but am unsure of how to set it up properly.

General browsing and downloading is fine, with good speeds at quite a high range, which is why im nervous to change the mode of the adsl modem. Please can someone give me advice?

:)

Modem is NOT a router it is a modem pure and simple all it does is route the adsl signal from the phoneline to the Ethernet port.

I'm sorry I thought I read somewhere that the 502-t is a modem but also has routing functions. There is an option in the admin panel for me to put it in bridge mode. If that option exists then I guess it has some routing functions?

Also it is referred to as an "ADSL Router" on the main screen of the admin panel.

Could my problems with utorrent be due to the hardware firewall on the modem? I have disabled the SPI firewall on my wireless router, as I have a software firewall setup I prefer.

Thanks,

What makes you think it is because of the modem? Have you tried connecting your computer directly to the modem to test bittorrent?

Hmm, hooking it up to directly to the modem would be tricky for reasons I won't go into. I have had it working before, when my computer was directly wired into a router that was in turn wired to the modem.

With this wireless setup now, the modem and router are 20m from my machine.

I think it might be the modem firewall because that remains the last thing I can think of, I have forwarded the port of utorrent on my wireless router, and disabled that routers hardware firewall. Should I also turn UPnP off on the wireless router?

When setting up port forwarding on my router, I left DCHP active, and used DCHP reservation so that my machine is assigned the same IP each time. Then I set a rule that opened the utorrent port for that IP. Still have no incoming connections on it though. Normal browsing and download throughput is fine though.

I just don't know how I should have my modem and wireless router setup to allow proper bittorent function...

Thanks so much for your replies already, I'm a bit of a self-taught novice at this.

Port has to forwarded on BOTH devices, on modem to WAN interface on router (static address) and on router to PC address (static).

If both devices are doing NAT (which is sounds like they are) then Spyware is right you need to forward the port on both devices.

Firstly from the Dlink to the ip address of the Linksys, then secondly from the Linksys to the IP address of your PC.
