Ok, so I have a device that sends out UDP data stream to a Linux host. The host is connected by an ethernet cable directly to a device. Device and host have fixed pre-configured IPs
[device]<---(cable)--->[networking card in Linux host]
I would like to use a WI-FI access point and wi-fi card in Linux host as a "wireless cable extender":
[device]<---(cable)---->[wi-fi access point]<----(air)--->[wi-fi card in Linux host]
The question is, how do I set up access point and wi-fi interface in Linux for such a configuration? It seems pretty basic, but somewhat different from the typical usage scenario, so I am a bit at a loss. Can I accomplish this with standard configs on access point, or I will have to load some custom dd-wrt firmware onto access point?
Also, what sort of packet "jitter" the WI-FI bridge is likely to introduce? I.e., if the device sends a (not exceedingly large) packet every 2 milliseconds, and the signal is strong, will the host see a packet every 2ms, or there will be significant irregularity introduced by the wireless bridge?
