[SOLVED] Intel 7260 Vaio can't connect to wifi

Hi there,

First off, I should mention that I know my way around Linux but I'm pretty new to Arch, so there might be things that I know that don't apply here.

So, I have this problem with this network, I can't connect to it and frankly I don't know why. I was on Ubuntu until a few days ago and I still had the problem. I posted on the Ubuntu forum >>here<< and I was told to upgrade, but as I've been willing to move to Arch for quite some time, I thought that was maybe the time. BUT, the problem is still there, which worries me.

To sum it up, about one or two weeks ago, I was connecting fine to this network (ZyXEL) and then after a reboot, no way to connect to it, no matter what I try. I have noticed an error message that keeps coming back all the time (see below) and the wifi indicator in i3status sometimes flashes me with an IP while I'm trying to connect then eventually the network disappears (not with wicd, only nm). Those are basically the symptoms.

I have had troubles with the wifi in the past (from what I read on the internet, this card is not yet fully supported everywhere) but nothing like this. Usually, disconnecting and reconnecting did the trick, sometimes I had to restart NetworkManager in extreme cases, but nothing more.

I tried a lot of things (modprobe, rfkill, firmware update, etc), rebooted everything I could but couldn't do anything. I have found bug reports and forums posts of similar problems but the solutions there either didn't work for me or the problem just seem to have disappeared for some people. I read that this card was not really supported before the kernel 3.11 or 3.13 but now I have 3.16 and it's still there. What's really bugging me is that I could successfully connect to this network a couple weeks ago...

On the Ubuntu forum, they have a script that displays useful information when posting about wireless problems. I have taken off the Ubuntu specific bits and I think this will save you some time asking me to run commands. One thing is not mentioned in the script: I use wicd.

Re: [SOLVED] Intel 7260 Vaio can't connect to wifi

Hi
I just want to say that I have the exact same problem. Wireless network suddenly stopped working last week on my Sony vaio. I'm on a wired network for now, but its very annoying.
If you found a fix or somebody else knows a solution, please post an answer smile

Many thanks
greets

I never found out what was causing the issue but after resetting everything related to the internet box, the problem disappeared. When I say resetting, I mean hard reset of all configuration of the router and the box.

While I am very pleased to have wifi working again, it bugs me greatly that I don't exactly know what the problem was. What I did was hardly the solution. If the problem ever comes back on another network, I might not be able to do this again (access to the box, permission to reset, etc). When looking for a fix on forums, all of the posts ended with the OP saying that the problem disappeared by itself. I guess this one is not any different anymore. Sorry about that.

Hopefully you figure out how to fix your problem.

Re: [SOLVED] Intel 7260 Vaio can't connect to wifi

I have the exact same problem, appeared completely random. I had several restarts this Christmas on the laptop, even after upgrades. I blamed the ath driver. But I noticed when I restart the router by plugging out it from the wall, then in again, sometimes it's working.

I carefully changed every possible settings in the router, then I found if I disable IPv6 (yes, it's capable of that despite Sky does not provide IPv6 service) it started to work even after multiple reboots. It took mi a while since the new year.

I'm using connman and when it was wrong, connman was completely frozen. If I entered "connmanctl scan wifi", it never quit. Same for "connmanctl state".

I also noticed that the router LED was blinking continuously and on the laptop when I checked the connection status with ifconfig it showed very high usage of TX packets. It also blocked the whole wifi, so my phone was not able to access the internet. Strange problem, I'm unsure what caused it and not quite sure how disabling IPv6 solved it. But I'm also afraid that maybe somewhere else I can't disable IPv6 on the router.

Re: [SOLVED] Intel 7260 Vaio can't connect to wifi

Hi,

On the router I was using, IPv6 was disabled from the beginning and changing this setting did not affect my computer.

I really don't know what caused the issue and as I was saying at the time...

Well, it happened again, on the same network, but I could not get access to the router anymore, so I was stuck this time. The router set up was a little weird though and I keep thinking that it was the cause. It was a box connected to a wifi extender that broadcast an impossible to configure network that I had to connect to. This is the only network that ever caused problems, so I'm really thinking that the network was at fault, not me.

Re: [SOLVED] Intel 7260 Vaio can't connect to wifi

I've had the same issue happen to me twice already. The thing that helped me was changing the channel of the wireless network (in the router settings). If it is set to auto, change it to any channel manually.

Good guess, I didn't think of that.


Anyways, all my problems went away a few months ago when I removed wicd (and any other NetworkManager kind of stuff) and went back to using the good old netctl tools. This might be completely unrelated, but my wifi works perfectly now.
