Wireless stopped working [netctl] [Solved]

Noxbru · 2015-12-22 21:02:46

Hi, I have a problem with my wireless connection. I configured it some months ago and it was working, then I moved and I have come back recently but the network doesn't work anymore. As far as I know nothing has changed in the configuration of the network.

I used netctl to configure the network using a simple wpa profile, and as said, it worked months ago. I have already checked that the password is correct, as if I change one letter netctl fails to start the profile. The interesting part is that netctl successfully connects to the network (at least iwconfig says that I am connected, and ping or w3m don't complain that I a not connected) But after that nothing network-related works, not even a ping to the router. I know that the network works (I am using it to post this) and my computer's hardware works too (I have checked with a liveUSB).

I am mostly clueless of what could be happening, any ideas?
If you need any more information, just ask.
Thanks in advance!

EDIT: I am now connected with ethernet so I can add more information.

rfkill says that nothing is blocked, `rfkill list`:

0: acer-wireless: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

This is what I get from `journalctl -f` when I enable my wireless profile with `sudo netctl start <profile>`:

I know that I am connected because iwconfig seems to say so:

wlp3s0    IEEE 802.11bgn  ESSID:"WLAN_0738"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: xx:xx:xx:xx:xx:x   
          Bit Rate=1 Mb/s   Tx-Power=16 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=70/70  Signal level=-40 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:1  Invalid misc:11   Missed beacon:0

`iw dev wlp3s0 link` also says that I am connected:

Connected to xx:xx:xx:xx:xx:xx (on wlp3s0)
	SSID: WLAN_0738
	freq: 2462
	RX: 2835344 bytes (24759 packets)
	TX: 2630 bytes (48 packets)
	signal: -39 dBm
	tx bitrate: 1.0 MBit/s

	bss flags:	short-preamble short-slot-time
	dtim period:	1
	beacon int:	100

Interestingly, the count of received packages goes up with time.

I have already tried downgrading wpa_supplicant, as it is suggested in this thread https://bbs.archlinux.org/viewtopic.php?id=196584 but it didn't help.

Edit 2: Solved by reconfiguring the router so that it doesn't use the 802.11n standard and fixing the channel. (Stupid routers)
