wi-fi extremely unstable

Post by zzacc »

Hi there,
l
I know there are other posts about this kind of problem. I've read some of them but couldn't really help myself out of this situation.

I'm running Mint 17.1, Cinnamon, 64bits. My wi-fi is really unstable. Sometimes I get a very slow connection, sometimes no connection at all, sometimes it normalizes, but then it fails and keeps asking the authentication code. I spent hours with no conection at all. Really really bad.

I have another computer, and there everything is running fine. So... I tried some things but, but I'm not very good with these things.

Please, can some kind soul help me out here?

Any kind of help will be appreciated.

Thanks!!

Oh... come on. Isn't there anybody out there to give me some hints? :(

I've been reading all these stuff about drivers and things and just can't really sort it out. Please help!! Internet is down every 2 minutes!


I suppose this will be of use for a potential helper... Thanks!

Atheros wifi in Linux don't cooperate with TKIP or WEP encryption from a wireless router. Be sure to have the wireless encryption on the router set to WPA2 only

It is set to WPA/WPA2 almost all networks around me are wpa/wpa2

EDIT: also "options ath9k nohwcrypt=1" in /etc/modprobe.d/ath9k.conf didn't help (rebooted the machine)

I might add, the machine sits exactly on the same spot and exactly connected on the same wireless network. It is fine when I am alone on the network, if there are multiple devices, it drops frequently. But it never happened in Windows8.

########## wireless info END ############

It's super weird I am not disconnected and I am able to send messages via pidgin/xmpp. However no webpage loads, even a small one, it's like port 80 and 8080 is dead. Even when I move the machine next to a router. The page never loads (firefox, chromium, midori were tested) even after long period of time, the only solution is to reconnect. XMPP messages however can be sent. No firewall is set.

It's been 2 days withou a drop of connection. :) I wasn't monitoring the connections on the router, so I am not 100% if it will hold :) But so far so good. Thank you very much @JeremyB

EDIT: "It has been a long time without a drop, so thanks again. :) There was one when Bluetooth were activated, since both mechanisms are one one chip, the bug is not big issue for me"

I have the same issue. Tried even this. Still there is issue.

Output of the command you posted: http://paste.ubuntu.com/13889940/

I am using 3.19.0-39-generic kernel. Please suggest something. I have a mobile connected to the same wireless AP. The mobile works fine while the speed is 0 in laptop

Wifi is connected. But no internet. I am planning to upgrade or downgrade kernel and retry. You had helped me once while i was on 3.13.0-39 getting the bluetooth of the same module to work :D .

Can you change the wifi router settings? If you can I would switch it to channel 6 or 11 and see if it works better

Tried. My broadband speed is 54kb/s. DOwnload starts of with that speed. Then drops to 0 in 2mins (approx). Then I disconnect my lap from the AP and reconnect and then again the same procedure repeats. :|
