No. 377	Re: Wireless Connection problem w/ EZL-80C	2007-03-20

When you flash the firmware to your EZL-90, you have to check if there are the CRC OK and PGM OK messgae in the background of wflash. Please flash the lastest firmware again. And you have to check the LINK LED while the wirless LAN card is inserting. (The LINK LED should be turned on if the EZL-90 i connected to your network.) > Randy Cook wrote: > ~~~~~~~~~~~~~~~~~~~~~~~~~~~ > I was working on a project and had been having a problem sending data to a uC from a laptop using the EZL-90 as the communicating device between the two. I had a wireless connection established, but every time I sent characters through Hyperterminal I received no response back from the uC. I know the code works as it has before, but I had made some changes to the parameters of the EZL-90 since that point in time and could not figure out the proper connection method. I noticed that there were firmware updates on the website for this product. I downloaded the avrw14e.bin file using the w21flash program. It said it successfully downloaded, but now I have not wireless connection at all. Presently, the only program that I can communicate with the module is the latest EZserialConfig_40g
