I apologize for the late response and limited information.
The patch doesn't work for me - same problems as before, i.e. the
patch doesn't
seem to have changed anything. I attached a log. I expect you can
make more
sense of it than I.
I can give you the model number of only one of the router/access
points - the
Cisco DPC3825 which I have. Unfortunately I can't offer much analysis
of it as
it's in modem only mode now and it's not very practical to reactivate
it as an
access point at this time. I could try to find out what my school is
using as well.
I've noticed that with the compat wireless drivers I'm ALSO
experiencing similar
problems with an RTL8188CU card. I expect that's relevant. Funnily
enough I have
three wireless cards on hand and all of them are some form of Realtek
card.
The vendor driver you are using,
/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012/, is
relatively old. My patches were for
rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0010.0109.2013, however,
since I wrote earlier, I found
rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0011.0128.2013, which
you will find on the Realtek web site under the RTL8188CE listing for
Linux. That one includes my feedback to Realtek about the 01092013
version, and it should build on mainline kernels through 3.8, but not
the current wireless-testing, but I doubt that you are using that
tree. With that driver, my RTL8723AE got throughput of 60-70 Mbps for
both RX and TX. I did have an unexplained kernel panic while running
that driver, thus there might be a severe bug in it. I don't know if
it is rtl8723e, but that is the only panic that I have had with 3.8-rc4.
The driver for the RTL8188CU/RTL8192CU is a mess. Unfortunately, I am
not getting musch help from Realtek. For that reason, I am
concentrating on the CE models. Their PCIe group is more responsive.

Sorry, just used to hitting Reply and NOT Reply All. It seems possible
that the problem may in fact be with the router. Or partially with the
router anyway. I DO have weak signal problems with the rtl8723ae Linux
drivers and always have but they may not be any worse than they were
before. One of my roommates is having trouble as well (though everyone
else using the router is fine as far as I can tell). I've noticed from
diagnostics with the router that most clients seem to be getting a ping
of about 6ms with occasional spikes, which seems a bit odd (I've
generally had pings of about 2ms with my own routers when I've checked
in the past) but I don't think it's necessarily anything to worry about.
I'll e-mail again if I can confirm with any certainty that it's either
the router or the wireless drivers.
