    This started happening on Wednesday
    All of sudden, my internet started run very slow! At 54.0Mbps and it never happened before...
    I'm using Windows Vista, I have Comcast Cable Internet, and a Linksys Wireless N Router, I don't know what just happened here cause now my internet runs very slow, especially when i download a file that is less than 50MB, any help?

    Does this just happen for wireless connections? Have you tried a wired connection as a test? Even at 54mbits, Comcast should run full speed.


    Download and run this Xirrus Wi-Fi Inspector, paste a screen shot of the Network screen here. Note that this application requires NET Framework to run. If you get an error about a missing function, download and install NET Framework.


    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.

    Alright just now i tried the wired connection by taking out the Ethernet cord that ran from the modem and the router into my laptop, check the internet speed and it was at 100.0mbps but when i ran firefox this message came up saying that the modem was obsolete... The modem is a 'Motorola SB4200 SURFboard Cable Modem'

    Comcast has doubled the speed here and it got worse as they was doing work but then got better. Still some slow routes but downloading is twice as fast in most places for me. But I think they are over loading the system at times because of the added speed.

    are you sure everything in the wireless chain is set to N and NOT to G
    G happens to max at 54mbps - the xirrus shows as N - but it might be worth a check, just in case the 54 is significant because of G limitations

    I checked it and it was N
    Although this weekend i did find out something, my brother had Bittorrent running at the time, did that program had something to do with the internet running so slow?

    You bet! Not only will it hog the bandwidth, but it also opens a slew of connections, and many routers will choke and lock up! You know where the issue is now. ;)

    aww geez..ok, so I guess our router and modem is fine, so about Bittorrent, would everything go back to normal if we uninstall it or do I have to do other things to make the speed work again

    P.S - What the heck is a bandwidth?

    i would uninstall bit torrent - also make sure you do not have any malware of virus on that PC now - although some sites are legal - most are not and full of virus/malware - just have a read of the malware forum here,
    so make sure your virus protection is upto data and run a full scan
    also run malwarebytes http://www.malwarebytes.org/ and superantispyware http://www.superantispyware.com/

    If you find the PC is going slow or other issues like popups - run a HJT log - see my signature for a link to the program - on the machine and make a new post in the HJT forum, and we can close this post

    Connect directly to the modem with one of the computers with a wired connection and post the following information.

    Run this SpeedTest and post the link to the results here.

    Run this PingTest and post the link to the results here.

    The speed for a wired connection is 100mbps The speed for a wireless connection is 54.0mbps Right now i don't think comcast is behind the slow speed, i think it's my router, i use a Linksys Wireless N WRT160N Router
