मैंने अपने नए लैपटॉप लेनोवो थिंकपैड E540 में ubuntu 14.04 स्थापित किया
मैं एक वाईफाई नेटवर्क से कनेक्ट करता हूं, लेकिन थोड़ी देर के बाद मैं कनेक्शन खो देता हूं, मैं फिर से कनेक्ट करने की कोशिश करता हूं, लेकिन यह किसी भी वाईफाई नेटवॉटक से दोबारा कनेक्ट नहीं हो सकता है। फिर से कनेक्ट करने के लिए मुझे कंप्यूटर को रिबूट करना होगा।
यहाँ मेरे dmesg कोड का हिस्सा है:

और यहाँ भी मेरा iwconfig आउटपुट है:
eth0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry short limit:7 RTS thr=2347 B Fragment thr:off

lo no wireless extensions.
मेरे द्वारा यह कैसे किया जा सकता है? मैं अभी वायर्ड कनेक्शन द्वारा नेटवर्क से कनेक्ट कर सकता हूं :(
क्या आप कृपया इसे ठीक करने में मेरी मदद कर सकते हैं?
