I have just install backtrack 5 r3 on my laptop so i can use it when im at work. I've installed it in my USB... At first the connection was good. Internet speed was fair.. The problem is with that every 5-10 mins, my wifi connection is severed... My laptop is an toshiba compact presario with a realtek wifi adapter.. I'va also installed it in my new laptop and there is no fluctuations in the wifi connection. Does anyone experience this same problem? If yes, any tip you can provide will be appreciated. Thanks in advance

Generally any issues you may have with a Wi-Fi connection pertaining to Linux of the Debian and/or Ubuntu based distributions is a result of the driver not being compatible or in some cases a lack of a driver altogether.
Which in this day & age is a rarity truth be told.
Most wireless issues can be solved with the appropriate driver being installed (obviously of course), even if it means compiling one for use in the kernel.
Notwithstanding one's wireless card being supported, which again, in this day & age via Linux, most are with-in a 10 year period.
Footnote: In my experience (infer personally), Atheros offers the best compatibility as well as simpler utilization for packet injection.
