checksum offload problem appears some of network card, but widely. RRS feed

  • Question

  • Hi

    did you heard about some of network card which support checksum offload functionality has an error in it? this may cause many problem like unexpected connection lost, most udp packet loss under a certain condition, or broken downloaded files, etc.

    recently, i have experienced this kind of problem while developing a network program in some of our company's computer. and i figured out that the problem is about the checksum offload error. it was really hard to find the reason.

    after i have learned about this, i asked my ex-colleagues and googled about this problem. so i noticed that the problem is not many but widely spread. and it's very hard to find the cause, hence the many people would have suffered from this error so far.

    although, erroneous network card causes this problem, but those of user who is not friendly with computer hardly can't update driver or disabling checksum offload option. probably, they wouldn't have know what causes their problem.

    hence my question is... does Microsoft has any plan to solve this problem? i think Microsoft can diagnose this and make workaround for this. and ship the solution via windows update. then many of users who suffering from this problem all around the world will be happy. and network programmer either. ;-)
