    Realtek RTL8723AE wireless drivers

    EDIT: Argh, now I've no connection at all. I've left home, and am trying to connect to my grandparents WiFi, but it just won't take it. The password box keeps appearing as though I've made a typo. I've checked and rechecked the password, and my phone (from which I'm posting this) seems to be having no trouble whatsoever. Any suggestions? The module seems to be loading still (i.e.it's still appearing when lsmod is issued), but I've no idea what to do to actually troubleshoot the driver

    UPDATE: Still suffering. My only internet access is through my phone (which is able to connect using the wifi password the PC refuses to take) - enabling USB tethering and then plugging it into the laptop (after Bluetooth tethering seemed to be more trouble than it's worth). Help needed fairly urgently, I want to have all computer problems ironed out before September (if possible, with the community's help).

    Hi all,

    Out of the box, the wireless drivers do work, but there are a few issues:

    1) Not long after installing, wireless networking was completely disabled because of a "hardware switch". The settings hadn't changed (the computer had just been rebooted, possibly following the standard package upgrade i ran after a fresh install). I tried rebooting and it fixed itself, and I forgot about it.

    2) Yesterday, the same thing happened again (after an upgrade of packages). The reboot didn't work, so I started researching it. I found some threads here which gave a terminal command which confirmed what the GUI was telling me - that apparently a hardware block was in place. I continued tried issuing commands probing the issue (I didn't get as far as changing anything) and rebooting - trying the function keys, BIOS etc. On the 3rd/4th reboot the issue solved itself.

    3) Wireless strength displayed is unreliable. At the moment it is regularly flipping between the lowest possible (whilst still connected) and full bars - without me moving position.

    I've tried messing with ndiswrapper in the past, and honestly, it was a nightmare - I'd rather stick with the native Linux driver, buggy as it seems to be. Does anyone have any fixes for the bugs outlined? Or could someone at least guide me through how to locate the package acting as a driver, and then it's maintainer - so I can raise the issue with them? Would launchpad be the place to file a bug report?

    Some basic information:

    Re: Realtek RTL8723AE wireless drivers

    Is "virginmedia8829612" your wifi access point (guessing by its signal strength)? If yes, and if you can, please try changing the channel from 6 to 1 or 11.

    If it is one of those which are using WPA/WPA2 mixed mode encryption, it is 'Strongly' recommended to change the encryption type in the router/access-point to pure WPA-PSK(AES) only, no mixed mode.

    In your laptop, please try the following -
    Code:
    sudo modprobe -rfv rtl8723ae
    sudo modprobe -v rtl8723ae swenc=Y
    Do Not Reboot after running above commands. The above is a temporary change and will be lost at next boot. If it seems to help, we'll make it permanent.


    PS:
    As for filing a bug report, yes, launchpad is the appropriate place to do so.
    Also, as you can see in the modinfo part of the script output, the authors of the driver and their email IDs are mentioned-
    Code:

    If you wish, you may use these emails to directly report the bug to them. Although I can't say whether or not you'd get a response.

    Issued the modprobe commands, to no avail. I'm a bit reluctant to mess with the router since it's not mine and I don't know what other devices may need to connect to it after I leave (and my grandparents are relatively technophobic, so wouldn't be able to sort anything themselves). I'm running Xfce, and there doesn't seem to be any option through the GUI to change the channel...is there a CLI I could access to attempt that?

    Since we're discounting the modprobe commands, should I reboot to undo the changes? Also, for my own curiosity, can you explain what the commands are seeking to do, and where you think the problem might be?

    I'll look into filing a bug report in the mean time, and/or emailing the authors. I'll post back here when that's done, thanks for the help.

    That was something to be done in the router itself, not in the laptop. Since you can't (or won't) do that, there's nothing else that can be done regarding that.

    Also, for my own curiosity, can you explain what the commands are seeking to do, and where you think the problem might be?
    The first modprobe command, due to the "-r" switch, removes the driver. The next one loads it again with the parameter "swenc=1". This parameter (swenc=1) shifts the burden of packet encryption from the adapter hardware to the software (OS/driver).

    It helps when the data stream is too fast for the adapter's hardware based encryption to keep up with (thus resulting in corrupt packets, causing fluctuating speeds or intermittent connection), since the computer's processing power is relatively much higher and it can easily afford that additional burden.

    However, now that it doesn't seem to help, of course you can reboot (if you haven't already).

    I think the problem may be driver's inefficiency. But there may be other issues as well which we may not have looked upon yet. I'm a bit short of time right now, will post back when (and if) I get time. Meanwhile, I may ask one of the senior members to look at it.

    As an absolutely blind shot, with no reasonable explanation at all, you may try Wicd instead of the default Network Manager. It does seem to help in 'some' cases.

    Re: Realtek RTL8723AE wireless drivers

    I was just suggested by Dr. Chili555, my senior most wireless guru, to ask you to run the script again 'Without' the usb adapter plugged in, as the Network Manager may not give us relevant results when two wireless devices are present at the same time.

    Accordingly, could you please try that again?

    Make sure the usb wifi adapter is not plugged in, let the internal card try to connect and fail, then run the script again (without the usb adapter) and post back the new result file. Thanks.

    My "internal" wireless adapter is going through one of it's funny periods at the moment, where it mistakenly thinks that the adapter is disabled by a hardware switch. There seems to be no reason for this: it just so happened from this particular cold start the driver decided to play up. As explained in the thread, rebooting would probably fix that, at least temporarily.

    I'll run the script never the less, and post the results here.

    That's with the "WiFi disabled by hardware switch" bug in the GUI. I'm going to reboot and see if I can get rid of that, and then I'll post again the output from the script.

    Btw, I also tried Wicd, I was getting some DBUS error, and couldn't get it to function at all. It ended up being purged, I'm back to using network-manager and network-manager-gnome now.

    I'm going to file a bug report too, and send an email to the authors - any suggestions on exactly what info I should send them?
