Wifi dropping after update

[rlritter1]

Hey all. It's been a while since I last posted (which is a good thing). Something strange just happened when I did an update. It seems as though my wifi will not stay up but for so long and then it drops without warning, and the only way to get it back is to restart the system. Turning the wifi off then back on doesn't even work. The last updates I installed before realizing what happened were mintupdate 4.9.0 to 4.9.2, mint-upgrade-info 1.0.1 to 1.0.2, and irqbalance 1.0.6-2ubuntu0.14.04.1 to 1.0.6-2ubuntu0.14.04.2. Thinking it would solve the problem, I went ahead and installed the latest upgrade to linux mint 17.2 rafaela, but unfortunately it did not work. I know one of the three updates must be the culprit because everything was a-ok yesterday and the only thing I have done to change things were those updates. I don't know if it will help, but here is the result of my inxi -Fxz:

Please help!

[rlritter1]

Oh yeah. I forgot to mention that my wife has a laptop with linux mint 17 as well and her computer is doing the same thing after the same updates. Any help would be greatly appreciated!

[Cosmo.]

installed the latest upgrade to linux mint 17.2 rafaela, but unfortunately it did not work.

What do you mean with "did not work". Your inxi-report shows, that you have 17.2.

Your inxi-report shows also, that you have the new kernel 3.16. Although is is the recommended kernel and gets installed with a new installation of LM 17.2, this kernel does not get installed, when you upgrade LM. For my understanding this means, you have installed this kernel yourself, but you did not mention it in your post.

Chances are, that the new kernel is the cause for your problem. Hopefully you did not remove the previous kernel (otherwise you would have to install it anew), so do the following:

Immediately after powering on press and hold the shift-key. This will present you the grub-menu. Open the submenu for old versions and select the old kernel and boot. Test it.

[rlritter1]

It did not work means it didn't fix the wifi problem. 17.2 installed successfully, yes. But my attempt was to fix the wifi issue. I really don't think the kernel is the problem. While waiting on a reply my wife and I have been doing some research and it turns out that the irqbalance may be the problem. She and I both went into the synaptic and downgraded it to the previous version and so far so good (fingers crossed). As stated, the only thing that changed, before upgrading to 17.2, was those three updates. That is when the wifi issue reared it's ugly head. If the kernel got updated due to the upgrade, then that was just an added update along with Rafaela. The wifi issue was already there before that. We are hoping this solved the problem. I will let you know otherwise.

Thanks!

[rlritter1]

Ok. Just out of curiosity, I went and looked at the older kernels I had available and it reminded me that I haven't done a kernel upgrade in quite some time, and the new 17.2 didn't install one, just as you said. So, that being said, it couldn't have been the kernel. Just as I was finishing posting my last reply the wifi dropped again. I've tried to just remove the irqbalance to see if that works. Otherwise, any suggestions would be greatly appreciated!

Thanks!

[rlritter1]

Crazy questions: What exactly is the irqbalance and what does it do? Is it necessary for my system? Could it possibly be what has caused the problem?

[rlritter1]

Dropped again even after removing irqbalance! I'm at a total loss!

[rlritter1]

Ok. Here's what I've tried so far. I've tried reverting back to a previous kernel, 3.13.0-24, even though it has been quite some time since I used it. No dice. I also tried stepping up to the next kernel on the list from what I have, 3.16.0-39. Still no go. I really don't understand what is going on here. I have done nothing since yesterday when everything worked perfectly except install those three updates I mentioned. Then, in an effort to try and fix the problem, I upgraded to mint 17.2 rafaela. Does anyone have a clue as to what is going on here? I'm stumped!

[JeremyB]

I would power off the wireless access point and turn it back on. Then in Network Manager set IPv6 to disabled or ignored.

[rlritter1]

Ok Jeremy B. I did that last night in a last ditch effort hoping it would help. Up to this point, it hasn't even offered to drop (again, fingers crossed). I don't understand this though. The IPV6 has never been turned off in the year and a half since I've had this computer and lived here at this same address with the same internet router. Why all of a sudden, after those three updates, would it suddenly decide it has a problem with it? As for my wife's laptop, she reversed the updates and it worked just fine, so far. Well, at least I have 17.2 now!

[rlritter1]

It just dropped again! This time I turned the IPV6 back on and tuned wifi off then back on and I didn't have to restart like usual. I'm going to try to take those updates off like my wife did and see if that works.

[rlritter1]

Can someone help me here. Which one of these is my wireless card:

Those are results from lspci and you have a USB wifi adapter a Ralink RT5370 using the rt2800usb kernel module

I would press the Shift key at boot and see if you have an older kernel available under Previous Linux Mint in the Grub menu

[rlritter1]

I have 2 older kernels available, 3.11.0-12(3.11.3) and 3.13.0-24(3.13.9). I loaded the 3.13.0-24 yesterday and it didn't help. I don't see how that could be the problem though because I have been running on the current kernel, 3.16.0-38, for quite some time now without any problems. Also, even though it says usb (Ralink RT5370 Wireless Adapter driver: rt2800usb) my wireless card has to be internal because the only thing I have plugged into the usb is my wireless keyboard/mouse. I'm confused. I thought lspci listed all internet drivers, ethernet and wireless. I tried typing lspci | grep -i wireless thinking it would list my wireless card, but nothing resulted.

Run

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

in terminal and post the info from the wireless-info.txt file it creates.

I am not sure what is going on as your inxi report showed

It might be a result of a bug but hopefully the script results will help find an answer

By the way, since I tried the 3.13.0-24 kernel yesterday and it didn't work, I am now running in the other older kernel, 3.11.0-12, to see if it makes any difference. Hasn't dropped yet.

Can you change the settings on the wireless access point? If so, change the encryption to WPA2 only or WPA2-AES as now it is using TKIP encryption and it usually causes problems and not as secure as AES only
