[SOLVED] Wireless USB dongle won't stay connected.

Hi!

I'm feeling awful by posting this, because there are plenty of information across this forum and the wiki, but after 2 months of a non-stop quest to make my internet work on my laptop (has a Killer WifI, not supported by the kernel), I finally give up and realize I need expert help.

Ok, heres the thing. I have this USB dongle which is a TP-Link something, and gnome 3.16 + networkmanager. The connection doenst seems to drop from the systray, because the wifi icon stays there, like it is connected. But after 1 min, 5 min, 30s, I feel the connection drop. My pages all stop working, and checking the system monitor I can see a traffic of 40b/s U/D. This keeps going. If i remove the dongle I can't reconnect to the previous network, meanwhile, I can try to connect to a new wifi. I can't deal with this anymore. I really need some help.

Thank you.

Hi,

Did you try connecting after disabling antivirus software, if you have installed it?

Re: [SOLVED] Wireless USB dongle won't stay connected.

Antivirus software?? You realize this is a Linux support forum, right?

mx_joa, you need to provide at least some information.
Type of USB dongle, what kernel module does it use, what log entries are produced when it disconnects, etc.

Re: [SOLVED] Wireless USB dongle won't stay connected.

You may be using a TP-Link usb wireless dongle that isn't fully supported by the linux kernel yet.
What is the specific model you are using?

Re: [SOLVED] Wireless USB dongle won't stay connected.

It's the TL-WN822N. I think it's not kernel related, because prior to this one I had the exact same problem with another dongle, but after some time and tweaks it got working. Tried this new adapter, that works for 5 minutes and then it drops without actually dropping the Wi-Fi. Trying to use the old one results in the same problem.

Re: [SOLVED] Wireless USB dongle won't stay connected.

Are you using the rtl8192cu (or similar) kernel module with this hardware? Hardware using this driver has been known to successfully connect, then drop packets and then drop the connection, before looping over and over doing the same thing repeatedly. You can look for these types of error messages using...

dmesg

I notice on the TP support website for your hardware, there is a linux driver which you can download that would give you an alternative 8192cu driver. Perhaps you could try building and installing that? There are also packages in the AUR, but I'm not sure if they are suitable for your hardware or not?

Re: [SOLVED] Wireless USB dongle won't stay connected.

You're right paul, they have a Linux driver in the website. http://www.tp-link.com/en/download/TL-W … tml#Driver

The problem is, how do I install it and include in the kernel? I mean, If this is the best way to deal with my problem

I love archlinux and can't switch to another distro and this is the only problem I have right now. And what a problem, no Wi-Fi connection sad

Thanks

Re: [SOLVED] Wireless USB dongle won't stay connected.

Solved the problem by installing 8192cu-dkms from AUR.
