youngs: Firmware 1.0.9.4 for GWN7000 released. Will try upgrading tonight once the wife is off the internet.
Good luck with it.
One of the first things I did when I got my 7000/7610 pair was switch of automatic updates. All of my updating has been via tftp, including a rollback from a beta version, quite some time back, to get back from mismatched software versions. I'm still on 1.04.23. The second link posted by @CutCutCut back on 06 Aug states explicitly that speed issues are still not fixed* so, as my UFB connection is being upgraded to gigabit (well almost) in 5 days, I'm not going to bother with this upgrade either.
*A subsequent question asking if speed issues are going to be fixed has not been responded to, which indicates to me that the answer is no. Given this I'm intending to start looking for a new router/AP set up in the new year.
