Prior to writing this post, i have searched various replies in your forums. After checking the recommendations and ensuring that they are ok, still the message "limited or no connectivity" keeps appearing.
I have Windows Xp SP2 on my system. I have checked device manager and there are no yellow marks. I have run winsock and still the problem persists. But still iam able connect to intenet and browse normally. While browsing some times this message "limited or no connectivity" appears and further connecting to internet takes few minutes.
I have loaded AVG free antivirus and Stopzilla. iam using HUAWEI ADSL router supplied by major ISP provider (BSNL) in india. Should i take this seriously and waiting for your solutions.
