Trying to bottom what I percieve to be issues with our wifi (Ruckus). What speeds should I expect to see, upload and download, when stood near an AP when I test it using the Ruckus speedtest utility? Using a netbook with its g rated card I get 20 down and with a USB n rated adaptor I got 40 down. Would have expected more.

What is the retry rate and the crc error rate ?
What data rate are the frames being transmitted at ?
How many other devices are visible and how many more are visible and active as you do your test ?

Done some more testing today and seem to have narrowed things down. Tried a test with two different Samsung netbooks and a Toshiba Netbook, they are the only devices connecting to the particular AP and all show zero errors in the speediest screen. These are the following results and also tried disabling the inboard wifi and using a TP-Link nano USB adaptor instead to see the difference. Quite a few repeated tests done to check for one off results. All had latest driver from manufacturers website when they were installed in the summer, running W7
Samsung N130 90Mbps Downlink, 43Mbps Uplink (Realtek RTL 8192e)
Samsung NB30 55Mbps Downlink, 6.0Mbps Uplink (Broadcom 802.11n)
Toshiba NB510 12Mbps Downlink, 580kps Uplink (Atheros AR938x)
Toshiba NB510 44Mbps Downlink, 12Mps Uplink (with TP-LINK nano USB adaptor)
The performance of the Toshiba surprised me but seems the Realtek chipset perfor,ed the best by far. Tried a Samsung NC10 with a qualcom chipset at another school on a similar Ruckus setup and had speeds as in my original post of 20Mbps Downlink.
Has anyone else had this where certain chipsets outperform others by this much. Just going to get a nano USB adaptor with a Realtek chipset now to see if I can get similar results from it.
@neilmac, can only say due to lack of knowledge what the speediest screen tells me so error is 0% but I have not a clue what the frame rate is! But from this further testing I can see what I should be getting and it's not 20Mbps Downlink!
