WiFi Data Errors

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.
