I have been using Vista home edition on a Toshiba laptop for almost 6\nmonths now without any issues when suddenly since last couple of weeks\nI am having networking problems.\n\nSuddenly in the middle of work the connection would be lost. I am\nusing wireless adapter.\n\nSo I investigated the issue but could not find anything conclusive.\n\nWhen this happens I am unable to ping my router. Initially I suspected\nmy cable modem / router but that is fine beceuase I have another\nlaptop that works fine when this happens.\nI tried ipconfig /release, ipconfig / renew.\nIt sometimes hangs OS on renew, sometimes just does not return.\nReboot always fixes the probelem, though when this problem happens\nVista does not shutdown cleanly, instead I have to hard boot the\nmachine.\nI suspected some latest updates from MS, so I undid them but this\npersists. I suspected some scheduler task that was periodically\nsending MS some reports, so I removed it, still no luck.\n\nThere is no pattern also, it just strikes anytime. The only thing is\nthat the frequency of this occurence is increasing to 2-3 times a day,\na week ago it was once in 2 days.\n\nAny help will be greatly appreciated.
