What does switching the router to 'AP' mean? If it was not an AP before, you 
would never have been able to connect to it.

One thing missing in what you posted is any messages from dmesg that describe 
the disconnects.

The only thing I noted in your posting is that your channel is about as badly 
chosen as is possible. Wifi is not like TV. The channel spacing is 5 MHz, but 
the width for 802.11g is 20 MHz, and 802.11n is 40 MHz. If you do the math, your 
choice of channel 9 overlaps *every* AP in your neighborhood. At -60 dBm, your 
signal is not strong, and is even weaker than Home2.

I would choose a channel as low as possible. That would be #1 for 802.11g. Your 
AP may not allow lower than #3 for 802.11n.

Next, you might try loading the module with the option "ips=0". That will 
disable power save mode, and it might help.

I have been running a long-term test of rtl8723ae. After 100 hours, I have had a 
total of 11 disconnects. Each of them has reconnected with very little 
interruption in service. The difference is that my channel is chosen to have as 
little interference as possible, and my signal strength is -44 dBm.
