I'm experiencing the same issue with Xubuntu 17.10 on my Lenovo ideapad320 (dmesg output attached) The card works quite well with a low load (chat or web navigation) but when I "stress" the connection downloading a bigger amount of data (performing a system update with apt, for example) the connection speed rapidly drops to 0. Sometimes I only need to stop the process which is downloading the files to restore the minimal functionality. Sometimes I need to disable and re-enable the wi-fi interface, but often the wi-fi controller freeze and i need to restart the system.
I made an attempt installing the kernel 4.15 rc4 from the mainline but this made the things worse. Many times, with this kernel, the connection freezes are followed by the unrecoverable freeze of the entire system. I don't know if it could sound weird, but i experienced this issue many times and i would not write it if I was not sure. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1653012/+attachment/5025292/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1653012 Title: 10ec:8821 [Asus X555L] RTL8821AE doesn't work after some minutes.
