I've dual-booted my ASUS X553S with Xubuntu 16.04.3 and have a couple of strange, but possibly related issues.

1) WiFi works OK, but if I disconnect and reconnect to my router, the wireless manager shows it as disconnected, even though it is in fact connected again.
2) <deleted>
2) This is a weird one - Software installs finish with an error, but turn out to have succeeded.

I speculate that these issues may all be related in some way, possibly to do with network drivers. Has anyone else encountered these or similar issues?

All advice appreciated. NB I have edited out any reference to Bluetooth problems.

I would not think that 1 & 2 are related. Software installs are a thing on their own, and that failing is an apt-get issue, surely; maybe a permissions thing?

Network is a NetworkManager issue - it's not picking up a dropped connection. As networkmanager is one of those things I love to hate, I can't help you there.

If you suspect they are related, it may be a python issue or something, if they're both using python.

If you're not wedded to Xubuntu, Slackware is not controlled by an automagic installer like apt-get, and you can go around networkmanager

Post some errors from the logs if you can find them. We can't do much without them.

There were a number of things which didn't seem to work properly, which puzzled me, since an online upgrade on another laptop produced a perfect 16.04 system. So I decided to download afresh and re-install in the same / partition, retaining my /home partition.

Everything now seems to be working fine, so I can only suppose that my original download/DVD burn was faulty. I'll mark this thread as solved.

Thanks for the input.

In the end I re-installed from fresh media, and all the problems seem to have disappeared. Many thanks for the input.
