WiFi Data Errors

Nov 09, 2004 1 Replies

I just spent 30 minutes on the phone with Linksys support. For two



weeks, my wireless net has been delivering errored packets to my



client. Not so bad when it only affected browsing. Refresh and you're



on your way. Today I was having bi-directional errors using Query



Analyzer with my database.


Linksys' solution was to change the wireless channel from 6 to 11.



While this resolved the problem, I was complaining that errored packets



should be detected by the TCP layer and retransmitted - not Linksys'



problem actually, the TCP layer is provided by MS in Win XP. Both first



and second level tech support at Linksys had no idea what I was talking



about. I finally gave up.


Am I wrong about this? Any errored packet, delivered over wire or



wireless should be corrected by TCP which operates between the client



and the server (as opposed to a link by link basis).

You are generally correct: when packets get dropped, the ACK should time out to the transmitter, and TCP should enter congestion recovery.

However, if enough ACKs in a row got dropped, then it would not be uncommon for the TCP implimentation to declare the connection to be unreachable.
