I'm currently running firmware 3.0.0.4.378_4585 and find that every so often I have to reboot in order to resolve extreme slowness on my iphone and ipad. I have 2.4 and 5ghz on separate SSID's. My ipad uses 5ghz. Last night it was painfully slow. Getting ~4Mb download on a 60Mb connection. Router reboot fixed it but I hate to keep doing that. Any suggestions on how to resolve this? Should I update to one of the newer firmwares? Are there any settings I should tweak?
