भरोसेमंद (कुबंटू - EDIT और अब उबंटू वेनिला ) को अपग्रेड करने (नए इंस्टॉलेशन) के बाद से , मैंने इस समस्या के निवारण के लिए वापस स्विच किया ) मैंने नेटवर्क के मुद्दों पर ध्यान दिया है।
वास्तव में हर दो मिनट में मेरा नेटवर्क एक पल के लिए तरस जाता है लेकिन फिर जल्द ही ऑनलाइन वापस आ जाता है। यह स्पष्ट रूप से syslog में परिलक्षित होता है:

मैंने अभी तक समस्या निवारण में बहुत समय नहीं बिताया है, मैंने केवल एक दिन पहले ही स्थापित किया है। मैं सोच रहा था कि क्या किसी ने इस मुद्दे को पहले देखा है? मुझे यह याद नहीं है कि जब मैं उबंटू 13.10 पर था, ठीक उसी हार्डवेयर के साथ 3 दिन पहले।

हां, यह मेरा कनेक्शन छोड़ने के लिए प्रतीत होता है। यहाँ एक विशिष्ट ड्रॉप से कुछ syslog है, मुझे इसे वापस लाने के लिए वाईफ़ाई को अक्षम / पुनः सक्षम करना होगा:

यह कितना निराशाजनक है। मैं हमेशा cat5 पर नहीं रह सकता। जैसा कि मैंने पहले कहा, यह कभी भी 13.10 पर खुश नहीं होता है। मैं वास्तव में डाउनग्रेड नहीं करना चाहता। क्या कोई तरीका है जिससे मैं 13.10 से वाईफाई ड्राइवरों का उपयोग कर सकता हूं?
इसके अलावा, मैंने WPA2 से 128 WEP तक अपनी वाईफ़ाई सुरक्षा को बदल दिया और अब तक मैंने केवल कुछ घंटों में एक बार डिस्कनेक्ट किया है। WPA2 पर यह औसतन हर 10 पर था।
