    Kernel 4.15.0-30 broke Wifi on my Surface pro 3

    Hi, I am not sure if this is the correct place for this.

    After receiving the latest round of updates kernel gets updated to 0-30 from 0-29 I immediately noticed inconsistent connections and after a few minutes the wifi adapter just stops working. A reboot will fix the issue but just momentarily.

    I had to revert back to 4.15.0-29 to get the wifi working.

    has anyone experienced this problem with the 0-30 kernel?

          Kubuntu has been super stable, i recently moved away from regular ubuntu due to bad wifi plus other annoyances. these are the packages that got installed right before the problems started. do you see any that would be related to wifi?

          I did sudo apt-get purge linux-image-4.15.0-30-generic
          thinking that was enough to revert back

          thanks for your help

            Did you install the driver for the wifi card, or was it present after installing Kubuntu?

            Updating the kernel could be a contributor the problem.

            Would you run
            Code:
            inxi -n
            and post the results. If it's not on your machine, just enter
            Code:
            sudo apt install inxi
            .

              I'm having similar problems on my HP-Envy. My wireless has never been rock solid, but it's gotten bad in the past day or two (about the time of the 0-30 upgrade). Basically, suspend-to-RAM has a good chance of killing the wireless on wakeup. No, it's not my router -- the Notification popup doesn't show ANY of the dozen or so wifi's in my neighborhood. Sometimes I have to play around for 5 minutes repeatedly suspending and waking up, turning airplane mode on and off. etc., before it gets back to normal. (Note that wifi stays on as long as I don't suspend-to-RAM.)

              "inxi -n" returns

              while "sudo lshw -C network" returns:

                So i am not sure if this is related but I noticed that this problem could also have been related or affecting my wireless router
                - a few days ago there was a power flicker and the router went crazy had to be reset
                - around that time the 0-30 update came in
                - mostly my surface was loosing wifi
                - I removed the 0-30 kernel but i still had wifi inconsistences but not as often
                - my wife just told me her phone was inconsistently connecting too i noticed my phone was a bit off too
                - i reset the router again.
                - so far everything is more consistent on all devices
                - I will let you know if the problem is gone from my surface

                I am wondering if the router could have been the cause of the disconnections and the 0-30 update made things worse.
                if i can get a consistent signal for a few days i will be looking to getting a new router

                thanks for taking your time into looking at this

                  So I ended up getting a new router and that fixed my issue with wifi. I still find it unsettling that a router can cause the kernel to go bonkers and kill the interface. I got the router Thursday (I am posting the following Monday) and ever since, my surface has been connected without any issues.

                  thanks for you help

                    If it's working now, but was intermittent or worse before with any kernel, it was very likely a communications/handshake error with the router that caused the interface to not work properly. I've had routers go bad - some quickly, some slowly - and it made the wifi (or ethernet) device look like it was failing. Hopefully all is well now, but come back if things are not working right.

                      thanks so much.
                      it does make sense. originally ubuntu 18.04 was inconsistent with the surface pro but installing to kubuntu 18.04 fixed all my issues until the power flickered and made a mess out of the network. i think it was just an unfortunate coincidence that the kernel update came at the same time adding to the confusion. so the router could have been going bad and the power flicker finally did it in.
