Poor Preformance, Mostly Windows Computers
« on: February 05, 2012, 04:02:25 PM »

I replaced a Dir-655 at a coffee shop, with a new dir-655 a few weeks ago.  They keep calling and saying that Windows clients are not working and that Mac clients do.

My first thought is that they are overloading the router but I would think that all computers would have problems not just the Windows computers. could the router be so bogged down that it takes to long for DHCP request for windows computers assigning the IP twice?

anyway, I turned on syslog and here are some strange logs...

Try changing wifi mode to single mode g or mixed g and n?
Turn off Short GI.
