EDIT: Following the steps in this thread
resolved the issue temporarily, before it re-emerged. However, following the steps again with the most recent backports seems to have re-solved the issue, despite the puzzling error messages.
I've just gotten Mint installed on a brand-new laptop after my old Windows machine died, and I'm having a few hiccups.
My WiFi connection has been dropping every once in a while--the time is highly variable; anywhere from a few minutes to one or two hours between drops. Turning my WiFi off and then back on from the panel restores the connection, but it drops again sooner or later.
The laptop is a Toshiba Satellite, and according to inxi -N the WiFi component is a "Realtek RTL8188CE 802.11b/g/n WiFi Adapter driver: rtl8192ce"; I'm not sure how to parse that.
This has been the case for two different WiFi networks in two different locations, so I'm pretty sure the issue isn't with the router; from what I've read, there are some problems with drivers not being compatible with Linux, but I'm not sure how to diagnose or fix the issue if that is indeed the case.
