Wired vs. wireless Internet speeds

    I not too long ago did a test to check my Internet connection speed using the Speakeasy speed test, and I realized that my wireless speeds were significantly lower than my wired speeds. After tweaking the settings in the DD-WRT firmware, I decided to give Thibor15c a try.

    To my surprise the speed tests gave slightly better results using Thibor15c firmware, but my wired speeds were again significantly higher than my wireless speeds. I decided to play around with my encryption settings to see if they were contributing to the slower speeds. Here is what I found:

    WAP AES = 2785(d) 360(u)
    WAP TKIP = 2455 361
    NO SECURITY = 2376 364

    So I deducted that the encryption method was not doing much to change the speeds.

    Now look at my wired speeds (using the same test server, at minutes apart from the previous tests):

    Wired = 7806(d) 361(u)

    As you can see the download speed is greatly reduced via a wireless connection.

    I tried disabling the firewall, disabling filters, but none of that helped. As I said before, this was also happening with the DD-WRT firmware.

    Do you guys have any suggestions? I am using a WRT54GS v4.

    Did you perform a similar test with factory firmware before upgrading to DD-WRT or Thibor?

    I tried the latest firmware from the linksys site, and I am still seeing the same speeds as the third party firmware.

    I have the same issue, I have a 6mbit/500kbit connection and wired speed test is around 5.1mbit/350kbit while wireless is less than half the speed. I am using latest Thibor on a WRT54GS, wireless signal is around 98% and uses WPA2. What could be causing this? I know there is interference and all, but to reduce it by that much? Thanks

    If you are using Windows, check and see what your Receive Window (RWIN) is set to for the wireless device.

    Check around there are articles and tools available for setting RWIN.

    Changing mine brought the wireless up to similar speeds as the wired connection.

    I went to dslreports.com and did its speedtest and also used DrTCP and set my RWIN and did the other recommendations. Still the speed is half of what the wired is testing at.

    how many wired clients do you have?

    have you enabled frameburst?

    have you tried a different channel?

    is QoS enabled?

    B mode, G mode or mixed mode?

    have you done anything at all to try and fix the issue?

    framburst is enabled
    I have 1 wireless client
    QoS is disabled
    G mode is on
    and I have tried different channels, I have chosen channel furthest from what anyone else around me has too. Still the slow speeds. I have tried increasing the transmit power, disabled security settings, and even making a makeshift reflector for the antennas all with no noticeable results.

    your wireless driver?
    have you tried a different card?

    I am new here but I ahve the same issue

    I have a WRT54G With DD-WRT Frimeware and I am on a 15MB DOWNLOAD / 2MB UPLOAd Fiber line, I get full 15/2 On my (this) computer I am on...but the family laptop I get only around 4.7 DOWNLOAD / 2MB UPLOAD

    I needed a new router becuase my old MR814 Was crappin out on me (plus it was piggy backed off a DI-604) I used to have 1.5/1.5 but now the U/L is obviously fixed, but not then D/L...Any suggestions?

    Does anyone know of a tool to check the speed from one computer to another? I want to see how fast my wired computer can send data to the wireless one and see if the speeds are same or not. The wireless is still getting around 2.5mbits/d and 480kbits/u but the wired is getting 5+mbits/d and 608kbits/u =o(

    Ok this is weird, when I make the ip addy etc all static by going to properties in Windows the speed jumped from 2.5mbit to 3.5mbit >,< now I am confused, didnt think that would be an issue. But still not as fast as 5mbit

    Thanks, this worked for me. My download speeds went from around 2 Mbps, to about 4.5 Mbps. Not as fast as my wired connection speeds, but definitely an improvement.

    My wireless device is actually a WUSB54GS and I am using the driver that came with it. I don't have any other device to test the wireless except that. Also before anyone asks anti-virus, firewall and any other network active software was turned off except what is required for Windows on the computer in case they were causing it. The speeds still remain appox 1/2 the speed of what a wired device would get.

    Man I wanted full 15 On my wireless...I thought thats why we bought the 54MBPS Speeds Router?

    itsmeohmy, do you have your WUSB54GS connected to a high speed USB port (USB2.0)? If it's connected to a USB1.1 port the USB will limit the speed, most likely to less than 5 Mbit/s. USB 1.0 would be even more limiting.
    Windoze usually says "This device can perform faster" if you don't have the WUSB54GS connected to a high speed USB port.
  15. itsmeohmy

    itsmeohmy Network Guru Member

    I dont know what version I have but its not 2.0 since Windows does in fact come up with message saying it can perform faster, but didnt think that might be cause unless its 1.0 if its 1.1 then should be well in range of the max 5mbit needs for the internet. I'll check it out later and past back the version the computer has. Its an old computer from around '98 so may be the case. If it is how would I go about handling that? Can I upgrade the USB? Cost? Difficulty? Thanks!

    From the wiki page on USB at http://en.wikipedia.org/wiki/Universal_Serial_Bus:

    * USB 1.0: Released in January 1996.

    * USB 1.1: Released in September 1998.

    * USB 2.0: Released in April 2000.

    So if your computer is from "around '98", then its likely its USB 1.0 since 1.1 wasn't even released until September of that year. That's very likely a significant factor in the slower speed of your wireless connection.

    As for upgrading, tough to say without knowing your computer. A computer from 1998 is ancient based on computer evolution. You may be able to install a USB 2.0 interface card if you have open slots available. Its very possible that the speed of the rest of the computer could still be the limiting factor in your ultimate wire transfer speeds, although using an USB 2.0 port would certainly help.

    Mmmm 1998. A Pentium I maybe? Which brings us to another issue. I think the overhead and processing that the computer's CPU must do to drive a wireless adapter is way more than a wired connection. Add to that the USB driving that must also be done by the CPU....

    A USB 1.1 port runs at 12 Mbps. When connecting my WUSB54GS to a USB 1.1 port on a 2.0 GHz machine, I get maybe 6 Mbps wireless transfer rate.
    Compare that to a USB 1.0 port, on which the USB speed is 1.5 Mbps as I understand. That will give you maybe 1 Mbps wireless transfer rate max?

    How do I tell if I have 1.0 or 1.1? Also the comps specs are as follows:

    OS : XP Pro
    RAM : 184
    CPU : 500Mhz

    Which should be sufficient to handle the wireless speed?

    doubtful, try a wireless transfer to a wired machine and see what speeds it can produce

    Whoa, Windows 2000 would run a lot better on that computer. Too bad the wireless support is not as good in it as in XP.
