I have a server/client application running in 4 internet cafes, and i have a packet duplication problem in one of them.
I have thoroughly examined my code and tested it in my lab and cannot find any bugs whatsoever.
So on rare conditions some of the clients seems to receive duplicate packets. (I installed wireshark to investigate the problem in the specific shop).
I am not sure if this is causing my application to crash but i have nothing else to blame!
So the question :
**Is there any chance that faulty hardware (router, switches, NICs) or bad drivers can cause packet duplication or packet corruption?? I even thought of viruses but firewall and antivirus software is enabled in all machines.
I am in a dead end and cannot think of anything here... If the problem wasn't in a specific shop only, i would re-examine my code but..
Thanks in advance!
