it is real good. i have used it and it is 10 times faster then a software implementation of tcp-ip stack. Earlier almost 50% time of uc was consumed in tcp/ip routines in particular checksum calculations.
now all that time is available for control application.
it is real good

| We had some technical problems using it, mainly related to software configuration, and we discovered that Wiznet support is not very good.

About our problems, mentioned before: they were related to firmware upgrade (we needed to upgrade some modules to the same FW version of others) but it was a problem due to some misunderstandings.
The thing is that in that case the thecnical support was very poor and slow, and this is not good when you start with new designs or components.

| Can you tell me guys how fast WIZNET? Is it good for data flow about 5-8Mbytes/second? How it compare to LAN91C111?

in theory it is capable of the data rates u have mentioned.
but if u are using it on a 8 bit or 16 bit uc then the botelneck is in uc not wiznet. 8051 has a instruction time of 1us or 1MB/S
