| 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). Sam |

A couple of things.1. How do you know you had packets that needed to be retransmitted?2. Why do you say it isn't a problem with the linksys?If you try to ping your router (usually 192.168.1.1) from your wireless client, and you get some packets timing out then you have packet loss. THis can be caused by many things (distance from router, interference from other 2.4 ghz devices, channel you are using for the radio, driver/firmware issues etc.) Sometimes you can have packet loss and not see it with simple ping test because the ICMP packets are so small and they slip through without problem. You can try to ping with a 64K ping packet with this command:ping 192.168.1.1 -l 65500 btw, 65500 is the max size you can send.It could also be possible that you have a problem with your linksys. It could simply be sending bad packets. You could test this by removing this hardware from the mix and see if your problems go away. Or you could check to see if you have problems on the wired connections too. If you do, then it most likely is a linksys problem, and not a wireless problem.btw, I run my router on channel 2, since everyone in the world seems to use channel 6. Make sure you are running current firmware on your router and that your wireless drivers are up to date.-ec |
