I have the rtl8723ae PCIe wifi card. I've read through the messages
on the
forums and experience similar issues to others who have inquired
about the
card. I experience sluggish connections and disconnects, I for the most
can't connect to my school wifi at all.
I switched my router to 'AP' today after reading through the posts
here and
initially the connection was faster than I've experienced thus
far(since
switching to linux last year), I ended up shutting down the computer
eventually and after turning it back on few hours later, It was back
to the
slow sluggish connection.
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.
I've collected all the output that I could think of and wanted to
contribute
it in hopes that it can assist the devs in testing/debugging the
issues with
the card. The text file is a little but over 800 lines, so I will
post it on
fpaste, if this isn't acceptable please let me know and I will
repost the
text in preferred format. I am about ready to smoke the beacons off
this
thing :P.
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.

Thank you for the prompt response, I really appreciate it. And I would
like
to apologize ahead of time in case I mess up the format.

Unfortunately my router has a check box under Advanced > Advanced Setup >
Wireless Settings that switches the router to AP Mode. I looked into the
manual after seeing the posting here and it's how I discovered it. It was
never checked until today.
From the manual:
"AP Mode. You can make the WNDR3400v2 function as an access point."
Page 77:
http://www.downloads.netgear.com/files/GDC/WNDR3400V2/WNDR3400v2_UM_23JAN2013.pdf
I also have a WNDR3400V2, which has been functional as a 2.4/5 GHz AP
for the two years that I have owned it, and that box has never been
checked. I have no idea what might be its effect, but it certainly was
an AP before you checked that box.
I believe (had a similar wndr device) that it has something to do with
the way the device bridges wifi to the lan/wan. On mine, with it
checked, I was able to use the device as a stand alone AP rather than an
AP/Router. Trying to do that without it checked enabled some additional
firewalling on the lan/wifi bridge.
The only thing I noted in your posting is that your channel is about
as badly
chosen as is possible.
Channel selection isn't done by me, it is set to "auto" mode at the
router
settings which explains that it will choose the best channel. I
appreciate
you pointing that out because now it will give me more options to play
around with. I have seen the ips posting else where and will test this
once
I configure the channel. Thank you.
I never select the auto channel selection. You never know what strong
sources in your neighborhood might be off when it makes the choice.
