Hello Folks, This would address both electronics and embedded engineers. Is there a method to coax a regular built-in WLAN port on a laptop (or a WLAN card) into piping out a simple and slow on/off data stream? Without protocols and all that, and without waiting for any receive packets. The reason behind this idea: Assume you have a small uC based product. Every once in a while it ...

Hi! Can anyone give me some links to WLAN serial(USB or RS232) converters, please? It may be an integrated chipset solution, an embedded board solution or even a ready device built in a case. Google gives me products of the following solution: serial-LAN-converter connected to a LAN-WLAN-converter, I hope there is a smarter way. Thanks!

Hi There, I'm looking for information regarding an embedded wlan repeater. I know I can get wifi modules to pick up signals from a wifi network or wifi router modules to distribute wifi data but how does a repeater work exactly? How do I redistribute the same data i receive without conflicting the receiving & sending network? Any information is greatly appreciated! Thank you! roN

Hi Embedded Group- I'm having a problem with my Lantronix WiPort module and I'd like to hear some non-Lantronix advice if that's possible. I'm not an experienced user of wireless hardware and software. I had a very early WiPort on a WiPort eval board from 2004. It stopped working after a few hours of use (WLAN ACTIVITY LED is held steady on whereas it would flash when it worked). ...

Hi, I have to interface a WiFi card (most likely PCMCIA, probably USB too) onto a board that also has a motor controller. The embedded motor controller traditionally uses an 8-bit microcontroller. But some of the users' desires now ask for network connectivity to monitor the motor controller, so I figure, heck, i'll give them a WLAN option too. I figure i can probably just add i2c or spi...
