WiFi associated but does not transmit packets [closed]

edit

Hi!

I have a Lenovo ThinkPad x230, which has a Realtek RTL8188CE wireless chip.

Since a few days, I don't have any network connection. The WiFi does associate, and NetworkManager claims that I am connected. However, "the internet doesn't work" and I can't ping anything. I get the following message for each ping:

ping: sendmsg: No buffer space available

or

ping: sendmsg: Network is unreachable

What is curious is that right after booting, ping succeed for a short period of time, about 30 seconds. Then the connection is dead.

This is definitely not a Router problem, because it happens on all of 3 networks that I have tested: My University network, my home network and using my phone as a hotspot.

I'm pretty sure this is a driver/kernel issue, because my Windows installation can use the WiFi just fine. (Well, it still has troubles - but at least it works most of the time).

Any ideas on how to get it working again?
