rtl8723ae Weak Signal Problems

rtl8723ae Weak Signal Problems

[Dylan]

Quick summary if you don't want to read my rambling:

  * Using the compat-drivers-3.8-rc5-1-u package
  * Using the rtl8723ae chipset and driver
  * Experiencing extremely weak signal
  * No clue what information I need to submit - I'm not having any clear
    crashes or anything, just a way-weaker-than-appropriate signal with
    a driver change being the only issue
  * Seems to have problems with Cisco access points (can't connect at
    all) but I'm not 100% certain

-----------------------------------------------------------------------------------------------------------------------------------------

So, I have a very specific issue with rtl8723ae chipset. I'm not having 
huge expectations of success but figure I'll just send this out there in 
the hopes that someone can help me. I'm using the 
compat-drivers-3.8-rc5-1-u package (the latest stable as of the time of 
this writing) which I'm pleased to see now includes the rtl8723ae 
drivers. Not a moment too soon as the hard-found drivers from Realtek no 
longer seem to work with the new kernels. Unfortunately, I'm now 
experiencing severely reduced signal strength and I'm not sure why. This 
adapter didn't have the best signal strength to begin with but was 
useable (again after a lot of effort). Now...I had this very same 
problem before. Then it was a lot better for the past few months. I'm a 
little hazy about what happened in between. I guess I 
did...something?...to fix it. I wish I remembered what. At any rate I 
now have to move downstairs closer to my router to be able to connect, 
and I have a very poor connection from in my room (it disconnected 
frequently and while it can reconnect on it's own it's still pretty 
annoying and causes a lot of problems).

Small piece of extra information: I actually haven't tested this yet 
with the compat driver (I wouldn't expect a change from the Realtek one) 
since I just switched to it the other day, but the rtl8723ae Linux 
driver (at least the one I was using before from Realtek) seems to be 
unable to connect to my school's Cisco access points OR the old Cisco 
access point provided by my ISP - I believe it's a problem connecting to 
Cisco access points in general since one of the networking teachers at 
my school mentioned some newer Windows 8 drivers having similar problems

Apologies if I'm resending this - I think my mail client got 
disconnected as I was trying to send this but I'm not 100% certain.

Strange that you see weaker signals with the kernel driver than with the vendor 
version. I get -56 dBm for the kernel, and -62 dBm for the vendor driver. I am 
using the code in the current wireless-testing git repo with some modifications 
that are currently under testing. Those changes will bring the kernel drivers up 
to the level of the 20130109 vendor driver.

If you want to compile the vendor driver under kernels 3.7 or 3.8, the necessary 
patches for rtl_92ce_92se_92de_8723ae_88ee_linux_mac80211_0010.0109.2013 are 
attached. The one named fix_build_3.9 is needed to handle the changes now in 
wireless-testing that will appear in mainline kernel 3.9; however, once the 
official version becomes 3.9, this file will need to be updated as the kernel 
version tests will then be wrong.

As to problems in connecting to the Cisco routers, I have no clue. I do not have 
access to a Cisco router with 802.11n capability. It might be helpful if you 
gave us the models for the routers that are involved. Perhaps some one else in 
the list will have had experience. Debugging this issue will probably come down 
to capturing the traffic in the air using wireshark, but we will forgo that step 
for now. In the meantime, please post the part of the dmesg output that shows 
the authentication/association sequence.

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.
