I found the solution! The driver was the problem. I tried using an external wireless adapter and everything works fine. Seems like the manually installed driver crashed under heavy load.

I have not used ownCloud; so what I am about to say may not be relevant. However, I have run into situations with Dropbox and other cloud services where I needed to keep chunk sizes to set amounts (20-40 MB) for large files. My second thought is that ownCloud (if memory serves correct, is PHP driven so you may need to modify your server's PHP settings to ...

I've solved my problem changing my router to an fixed channel (3 on my case). I've tried a lot of things like changing my drivers, updating my kernel, but realized that is a lot of wireless networks on my range and this might be conflicting with mine because I had this problem only on one of three networks that I use and on the other two it has no problem. ...

Why are you doing this? If this is the 3.13 kernel, it should already have support for that chipset, since late 2013, if I am not mistaken. Never use out-of-tree drivers without justifying it.

I had this problem occur on two machines connecting to Ubiquiti's UAP-LR access point. No matter what I tried I could not get this to work by tweaking the config / modules, etc. on the laptops. I was running 2.4.6 of the unifi controller software, which is the latest "stable" version. I installed 3.2.1 which immediately upgraded the firmware on my AP and ...

"Hard Blocked" refers to a hardware issue and "Soft Blocked" indicates the connection is blocked by software (rfkill for example). In other words, rfkill commands have no affect on a hard blocked device. Check for a physical switch or possibly an fn key that can toggle the wireless on and off. Make sure wireless is enabled in BIOS. If you have a BIOS ...

Are you sure you installed the additional wireless drivers? I have had the same problem, and if you haven't got your wireless drivers you would need to install them and then (if not already) turn on your wireless card. After that, you may need to restart your computer, if that doesn't work then try typing the command: rfkill list all And if it shows that ...

It may work if you first bring the interface down: sudo ifconfig wlan1 down sudo iwconfig wlan1 mode monitor Check: iwconfig Not every device and driver combination are capable of monitor mode.

The best way to put your Wifi adapter to monitor mode is through airmon-ng. You can install it by typing into a terminal sudo apt-get install aircrack-ng Also, if you are using Wireshark, you have to run it as superuser to be able to put your adapter to monitor mode... :)

Probably you used the wrong sysntax. Check /var/log/pgl/pglcmd.log for error messages. Generally it is easiest and safest to just use pglgui and right-click in the log tab on any blocked connection that you want to whitelist. The decision whether you want to whitelist any IP depends solely on your personal needs. Just don't whitelist simply an IP (or ...

The Broadcom wireless driver provided by bcmwl-kernel-source, as well as some older Intel drivers, names the wireless interface ethxy, where xy is the next available eth interface name. The driver does provide a parameter you may change. I have no Broadcom card so I've never tried this, so the process may or may not work as expected. In a terminal: sudo -i ...

If the installation was interrupted, you might get good results by fixing it with sudo apt-get install -f I just had what I think was the same problem OP had, starting manually the Network Manager provided me with the icon in unity, but no interfaces visible, while the above mentioned command and a reboot fixed the issue completely.

I too had the same trouble when installing Linux Mint, Ubuntu 13.10 and 14.04.

Since you have a Broadcom radio I recommend the following hook up your laptop to an Ethernet cable to get it online.

Solved! All I needed to do was to configure the hostapd.conf file with minimal settings, no script or additional applications required. What I did was that I first created an Ad-hoc network with Network Manager, as described in previous answer, and made sure I was connected to it on wlan0 and that I still had access to internet through wlan1. I then created ...

This is a known problem with the device itself, it also happens on Windows. In the following monster thread with more than 70 pages, you can see that over a period of two years Intel is continuously failing to fix this device. And it looks like they will never be able to get it working. The only solution is to toss this piece of crap card out of the window ...

There are many ways to do this. I would recommend a solution based on LDAP for authentication and user management, and NFS for storage. In the following, I assume that by "Terminals" you do not mean X server forwarding, but actual local sessions. For actual terminal servers the server runs the applications, and the client simply displays the "GUI". More ...

There is nothing wrong with your network, it's not a bug, it's a feature of TCP/IP: let's use full available bandwith, and it saturates your network easily (router gets too busy). You need to embrace Quality of service (QoS), read about it and configure it. There should be related options in your router. Take a look at page 28 in the Linksys E2500 user ...

I just tried this out to verify that it works. No hostapd and no access-point script. Instead of an "access-point" this sets up an "ad-hoc" network using network-manager.

OK, I could tell you to try another git protocol, but this would be only a workaround. If I were in your place, I would connect the Mac and the Ubuntu through a vanilla Ethernet hub and see what happens with a sniffer program like wireshark.

sudo rmmod -f ath9k sudo rfkill unblock all sudo modprobe ath9k Then suspend and wake up your laptop. Your wifi should work. That worked for me, but just until I shut down my laptop, then I need to do the same thing again when I turn it on. I found the above commands in some other question.
