Usually, 40-bit WEP (64 bit key) can be cracked with 300,000 IVs, and 104-bit WEP (128 bit key) can be cracked with 1,500,000 IVs if you're out of luck you may need two million IVs, or more. The number of required IVs depends on the WEP key length, and it also depends on your luck.

The DeviceManager\wifi adapter\Advanced Properties = Multimedia Gaming Environment is Enabled. In the registry you will find similar keys, where you can adjust the TXPower of the client and the Roaming Agressiveness.ĭriver Version 3.2.1.0 dated from Ralink website. While this adapter might be a few more $$$ it appears to be much more consistent than the D-Link or Linksys adapters in terms of roaming and even in terms of authentication time using WPA/TKIP/802.1x.Īlthough RaLink does not provide the ability to setup these cards for enterprise environments, the setting are still available none the less. We’ve since gone back and starting using the Netgear WDNA3100 which is based on an Atheros chipset. It was definitely MUCH better behaved with Fast roaming enabled but it was no where near where we needed it to be.

While the adapter seems to work fine once your connected and in-mobile it was hit or miss once you started moving or if you just picked up… walked 200 ft and tried to work again.

Initially we thought it might have to-do with the WPA/TKIP/802.1x configuration with Windows XP and the re-authentication as the STA roamed from AP to AP but even in a open network we had issues. Unfortunately I had to drop the D-Link adapter… even with Fast roaming enabled (85dB) the adapter seemed to throw fits from time to time. Has anyone else seen any issues with either the D-Link DWL-160 or the Linksys WUSB600N in a corporate network with respect to roaming? I can’t imagine that we’re the first folks to stumble upon this issue given that Ralink Technologies chipsets are in all these products. We did find that if you enable “Fast roaming”, which can be found the in the Advanced Properties of the RA utility the STA behaves much better but it’s still a world apart from the roaming performance that we’re accustom to.

We’re in contact with both Motorola and Ralink Technologies and we have tried Ralink’s reference drivers (1.4.1) along with a beta driver they have provided but we haven’t seen any real improvement. We’ve performed multiple wireless packet traces using AirPCAP and WireShark and they don’t show any issues with the wireless access points, however, they do show a lack of probing and some odd behavior by the wireless adapters (STA). We started to peel back the onion and almost immediately found that both products were based on the Ralink Technologies chipset (RT-2870). The big surprise came we noticed that the Linksys behaved exactly like the D-Link in that it would not roam which would lead to poor connectivity. We quickly noticed that the problem was not only evident at the 2.4Ghz frequency (802.11b/g) but also evident at the 5 Ghz frequency (802.11a). We also removed the authentication (802.1x) and encryption (WPA/TKIP) and just test using an open network. We decided to simplify our testing environment by removing the Windows XP Embedded (Thin Client) and test on a simple Windows XP SP2 laptop. So we purchased a Cisco Linksys (WUSB600N) Wireless-N USB Network Adapter with Dual-Band. We had a really large project and the time frame was extremely tight so we decided to run out and pick-up a different adapter. We noticed that the DWL-160 didn’t want to roam until it had lost complete signal to the AP it was associated to and then only after about 10 – 15 seconds would it roam to another APl. A few weeks later though we learned we had a problem with the combination and we eventually discovered that the problems revolved around roaming. Our initial tests showed no problems in connecting to our Motorola RFS7000 with AP300 (802.11a/b/g) radios utilizing 802.1x (WPA/TKIP). We utilize HP Thin Clients on our carts and have been pairing them with USB adapters for the past year and a half (saves on having to purchase the chassis expansion kit and the PCI card). The legacy D-Link DWL-AG132 (802.11a/g) was no longer being manufactured and/or available from suppliers so we selected the D-Link DWL-160 (802.11n/a/b/g) and that’s were the fun started. We recently needed to replace the USB based wireless adapter we use in our CoWs (cart on wheels).
