    I'm having problem with slow wireless trasnfer speeds. 129kb/s slow. So here is my set up. Desktop with a 100MB nic card, running windows 7 ultimate, connected to linksys wrt320n running dd-wrt. then i have my laptop running windows 7 ultimate, connected to my wireless network.

    I have tried coping files in the homegroup and outside of the homegroup. Any help or suggestions would be appreciated.

    Anything else using the wireless network?

    What download result do you get with a Speedtest.net test?

    Are the speeds about the same copying to and from the laptop?

    For the laptop please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector.

    From the Desktop to the Laptop: 1.5mbps
    From the Laptop to the Desktop: 1.25-1.5mbps

    I rejoined the homegroup, and rebooted my desktop and my speeds bumped up. I have 2 xboxs hooked up and am streaming windows media center, in the network performance area it has full bars. So stuff is flowing freely from my router.

    Wireless devices connected
    -2 Laptops
    -1 Ipod Touch
    -1 Andoid Phone
    Wired
    -2 Xbox 360s
    -1 desktop

    I think that you will have to try when there is no other use of the wireless to determine if you really have a problem or are just experiencing congestion on your WLAN.

    I did give it try just a few minutes ago, except you beat me to the keyboard...=D
    Running 3.5mb now. but it still seems slow since it shows my connection at 130mbps. So should be at least getting 16MB right?

    I can't see any problem with your network, so I don't know what the problem is. I have been able to get ~65 Mbps copying a large file over ethernet to router to laptop via wireless connected at a nominal 270 Mbps. So, I would expect you could get at least 30 Mbps (~ 4 MBps).

    Wow...wish i could hit those speeds. I'm going to jump both pc's off the homegroup and then test it out. Is it possible its a windows 7 problem?

    I went into my router and set it just to wireless N and im getting 9MB = 72mbps. Now I wish I didn't have any G devices. I do have another WRT54G that has ddwrt on it. maybe i will set that up to broadcast wireless G, and keep my 320N for Wireless N only?

    See any problems with this set up?

    Keeping the N and G devices separate like that would be good--not only allow the higher speeds on the N network but would cut down congestion possibilities on each network. If you want all your devices to be on the same network--be able to access each other--use the 2nd router as switch and wireless access point ...

    JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

    For reference, here's a link to a Typical example config using a Netgear router

    Perfect. I set it up and it works like a charm. Fast transfer speeds and all. Thanks TerryNet for your help!
