Trouble connection to certain wifi APs

andy123 · 2014-10-08 10:28:10

So I've been having trouble connecting to some wifi access points over the last half last year or so. The weird thing is that my notebook stopped connecting to one AP which works for other devices, used to work with the notebook and now it connects to some networks (like eduroam) but refuses to connect to others, like my access point at home. Other distributions and operating systems, like Kali Linux and Windows 8 connect fine to the same access points on the same notebook.
My hardware is a Thinkpad Edge E325 with this network controller

01:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter [10ec:8176] (rev 01)

The kernel is the latest stable 3.16.4 and wpa_supplicant is 2.2-2, but I think it's been happening since somewhere around linux 3.13.x.
The logs I could gather are useless to me. Here is NetworkManagers journal output:

This problem might actually solve itself, since I'll probably give this notebook away in a few weeks, but I'd still like to find the reason for this.
