RealTek RTL8188CE WiFi adapter doesn't connect reliably
I have an ASUS PCE-N15 in my PC, which I connect to my home network with
NetworkManager. I use "WPA & WPA2 Personal" as a security method. The problem is that after some time Wi-Fi connection almost dies, stops working almost completely. Why I say almost is because some packets do flow from time to time, I can ping something (but with huge times like 1 second), but its exiguous, visiting sites doesn't not work. Nothing is written into syslog,
dmesg shows nothing too.
There were several topics on this, including some solutions like changing
sysctl variable or lowering security level, but it doesn't help.
