Got a Trendnet tew-624UB 300Mbps newer revision wifi usb dongle. Works just fine!
On checking connection information on n etwork manager it shows up as a 150Mbps device using rtl8192cu as a driver. This device is a 300Mbps wifi dongle.
The maximum TX strength is 80% and signal strength 100%...which is just fine! But i have no range?!! Checked with the router touching it and its still 80 % On checking this device with win7 everything is 100% running @ 300Mbps........it catches 2 floors strong signal but not with ubuntu 12.04! Simply put the "rtl8192cu " is a 150Mbps driver and not 300Mbps.
Is there a 300Mbps driver or an upgrade path for this device that i can use far away from my 300 Mbps router..... it works fine @ 150Mbps but with no range.
