Is the issue described here also causing slow speed on 2.4 ghz? I'm getting very slow d/l (8mbit) and u/l (20mbit) on my 500mbit/40mbit internet connection.
Using two R310 with unleashed 200.7, only happens with 2.4 ghz and is temporarily solved by disabling/enabling wifi on phone.
After that speed is normal again, happening on S7, S8 and S10. But after some time (maybe half hour) it's down to ~8 mbit again.
On 5 ghz I'm seeing same speeds as described in this thread. Issue was not always there and started after a fw update, not sure which.
Made a case at ruckus but was told my support contract ended and was not entitled for help.
Crossing my fingers that the coming update described here will also fix the abysmal performance on 2.4 ghz.
