If the adapter is disabled, the application doesn't crash right away - but the second it's enabled, it crashes with no error log in the program's folder. The second it finished installing, the REALTEK software crashed and it continues to do so as long as the adapter is enabled. However, a few days ago I installed an updated version of the driver through Windows Update. For over a month I had been using it with the drivers included on the CD it came with, along with a tool called 'REALTEK USB Wireless LAN Utility' to manage it - enabling and disabling it, and most importantly easily configuring my adapter's access point mode. Second, I am curious if there are any settings in the Device Manager entry for the adapter that would improve performance? I would am running them them in the 5GHz 802.11ac mode, both for better speed and to free up the 2.4GHz band for all the other devices that only support that band and aren't as performance-sensitive.I have a usb wifi adapter by 'Glam Hobby', which I can link to if required but basically it's just a rebranded Realtek USB wifi adapter.

If anyone could point me to the latest driver for download, it would be appreciated. The Alfa website lists only one Windows 7 driver, and it is six months old - messages to their tech support have gone unanswered. I've also seen the 'rtwlanu.sys' cause a BSoD, which makes me suspect the drivers are buggy.įor starters, I'm having a hard time finding the most up-to-date drivers for the RTL8812AU chipset used by the AWUS036AC - strangely, there seems to be no listing for it on Realtek's website.

What perplexes me is the variability of signal strength I'm seeing from hour-to-hour and day-to-day, and the fact that rebooting the computer almost always seems to improve the connection. I am connecting them to a TRENDnet TEW-812DRU AC1750 dual-band wireless router. I've purchased several Alfa AWUS036AC 802.11ac dual-band wifi USB adapters for use with three Windows 7 computers I have, and I am looking to get better performance out of them.
