    hey guys, i am kinda new to wireless networking- my friend gave me a linksys wrk54g the other day, and after about 5 hours, i got the computer in the other room working via a usb wireless adapter (my computer is connected via ethernet cable).

    everything was working fine, until i noticed utorrent wasnt working, and then learned i needed to forward a port for it- so i did so: i set a static ip in windows, then forwarded a port in my router for utorrent. at that point, utorrent began working perfectly, but i had another problem- the computer in the other room connected wireless doesnt connect to the internet now. it still shows as connected to my router, but nothing internet related works. i went in on that computer as well, and set a static ip.

    like ive said im pretty new to this, i dont understand what it is about port forwarding that would cause the other computer to cease connecting, so any advice would be appreciated

    This sounds like the classic problem with torrent applications consuming all available bandwidth by default. You need to set up global limits in micro-torrent that will prevent it from hogging all the bandwidth for itself. Under network options establish a global upload limit of about 50% of your upload capacity. In torrent options set the global maximum number of connections to 300. This will keep it from swamping your internet connection. If you have one single torrent that is maxing out your download, right click on that torrent, and in porperties, limit it's download speed to 60% of your download capacity.

    thanks for responding- but im wondering, if that were the case, wouldnt the computer connected via wireless work correctly if utorrent werent even running?

    Yes it should and who really knows whats the cause at this point. Is the wireless machine getting an ip? If so is it getting dns? Can you ping the router? Can you ping past the router? Once we get an answer to these we can move forward.

    well, like i said im new to this, but in my router config, it says the ip range is:
    192.xxx.1.100 - 192.xxx.1.149

    so when i went in to set my ip static in windows for port forwarding, i assigned my computer the ip of 192.xxx.1.100, and i set the dns and gateway according to what i saw in ipconfig. at this point utorrent began working well on my computer.

    i then went into the other computer connected via wireless, and set it static, with the ip:192.xxx.1.101, with the same dns and gateway as my computer. it shows as connected to my router, but like i said, nothing net related shows up.

    im not totally sure if this is the correct configuration, but hopefully someone here knows :biggrin:

    No need to worry about typing the ip address that your router hands out as no one can do anything with it. I am going to say its on the laptop. What dns did you use? Did you use the router itself or did you use your isp dns? What ip are you using as the default gateway on the laptop? What happens if you open a command prompt on the laptop and ping google.com?

    i've had it backwards:

    here i wrote
    if i wanted my ip to be static, i shouldve set my ip to a value outside of the above range, not within it.

    i'll report back as i get this knocked out:biggrin:

    Static is static, when using an ip withing the dhcp scope all you do is run the risk of having a duplicate ip. In your case you only have 2 machines so that wont matter. Just make sure you double check all of you setting when implementing.
