Getting WRT600N wireless dropouts on 5ghz band? We recently upgraded from a WRT54GL router to a Linksys WRT600N Linksys Ultra RangePlus Dual-Band Wireless-N Gigabit Router to take advantage of the dual band 5ghz and 2.4ghz wireless N frequencies along with the gigabit wired network connection. Initially, we were disappointed to find that while working via the 5ghz band on our wireless workstations, we would get randomly dropped connections. This would typically occur when doing large downloads (receiving large packets). All of our workstations use Intel 4965AGN wireless cards and we never experienced a hiccup on 2.4ghz frequency with the old WRT54GL router.
As it turns out, the fix was quite simple. We simply needed to update to a newer driver for the Intel 4965AGN cards on our Windows XP systems. Once the new driver was installed, our Windows XP systems performed flawlessly again on the 5ghz band. So if your experiencing dropped connections on your wireless network, read on:
How to fix the WRT600N drop outs on the 5ghz wireless N band:
This assumes that your using an Intel 4965AGN Wireless card and your Operating System is Windows XP. Vista users would need this driver from Intel.
Click Start -> Run and type devmgmt.msc and click Ok
From the list, double click Intel(R) Wireless Wifi Link 4965AGN under network adapters
Under the driver tab, check your driver version. If the version is 188.8.131.52 or later, you don’t need a new driver. If your version is less than 184.108.40.206, read on.
