    Wireless has unusually slow speed
    « on: January 27, 2010, 10:34:46 AM »
    I've just recently bought a new Dell Studio XPS 13, and I've been having problems with my wireless connection. Connection speed has been really slow (10x slower than usual). Initially I just thought my ISP is having some sort of maintainance but it's been going on for 2 weeks now. So I tried connecting my laptop using an ethernet cable and the connection speed is back to normal. I also tried connecting wirelessly with other laptops and everything was going smoothly, connection speed was as it's supposed to be. So any idea why my laptop has such slow wireless connection speed and how i could fix it?

    What's the make/model of your wireless router?

      oh ya, forgotten to mention, sorry  :-X
      My wireless router is a Linksys BEFW11S4.
      The wireless adapter of my laptop is a Dell wireless 1510 wireless-N WLAN Mini-Card.

      To start off, your router supports only "B" standard so the maximum throughput of your wireless card in the laptop, and all other laptops using the wireless router will be 11 mbps, as opposed to 600 mbps (max. of wireless-n)  However, you should still be able to get decent downloading speeds with that, assuming there is only one user on the router...  If there are multiple people using the router, 11 mbps would not go very far.. Say 3 people wanted to use the wireless router, then each of you would be limited to approx. 3.6 mbps.  On top of that, the /b standard uses csma/ca, a protocol used to regulate data being sent over the wireless network, to avoid colliding with other wireless clients, which bogs down the wireless environment even more..

      Assuming that you are the only user on your router, try booting into Safe Mode With Networking...  Restart the computer and tap f8 until you see advanced boot options... Select "Safe Mode with Networking", then connect to your wireless access point, however it is you do that, whether it is through DELL proprietary software or Windows 7...  If you cannot find how to view wireless networks available while in Safe Mode, go into Control Panel, click on "classic view", open "network and sharing center", on the left, click on "manage network connections", right click on the adapter you see, and click on "view wireless networks.. Find yours, connect and check the download speed, if it has improved...

      I didn't ask what the signal quality is when you use the laptop..
      How many bars are you getting?

        Well, I'm getting full bars.
        Will try Safe Mode networking. If that works, i can run my comp as usual after that?

        If it works in Safe Mode with Networking, it just means that there is likely some software, services, or virus interfering with the connectivity, while in normal mode...   Another way to put it, is we'll have to run some virus scans and disable programs and/or services until we find out which is causing the disruption..

          Was it working good when you first got the laptop, or was it always slow?

          If it was working, what has changed since you first got it?

          Let me but in.
          If this is a brand new laptop and if is the only machine having trouble with the wireless speed, then it may be a good time to call the Dell tech support.

            Nah, has always been slow. I'm using a McAfee Anti virus, maybe it has something to do with it?

            maybe..


            @ starlight    What wireless technology are the other laptops using?

            Are they using "B"  "G" or "N"  ?     

            For example, your new laptop is "wireless - n"

                Not very sure bout the laptop using the Atheros AR5006EXS Wireless Network Adapter. But the other one is using an Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter,which I guess is "B".

                The first one you mentioned supports  "A", "B", or "G", and the latter supports only "B"

                At any rate, since you are getting Full Bars with your new "N" laptop but having a slow connection, while the other laptops are older technology and work well, I suspect that you need to update the firmware of your Wireless "B" router..  Although "N" is compatible with "B", a firmware update may be necessary to ensure full compatibility..The two technologies are about ten years apart..

                If your other laptops were using "N" and working well, then I'd say take the laptop back to DELL..

                Look on the bottom of the router, next to the model number and tell me what the version number is.  It should say something like Ver. ?  If it only gives you the model number, then it's version 1
