ttmcmurry, Errm, how about getting his internet sorted out before you try to fix his poor wireless signal? For all we know the firmware upgrade could have fixed that anyway. The problem is that he can connect to the router but no the internet, so it has nothing to do with wireless settings.
While a valid point; he said he was connected at 32mbps via wireless. That tells me there is a signal issue. Where there is bad signal there is lag. Where there is lag, there is all sorts of issues waiting to happen. More importantly, changing settings on the router can
mask wireless signal as an issue - meaning it's still there, but you don't see negative side effects as often (read: extra wireless protection).
That's why I said: START WITH THE BASICS. Do a site survey, post the graphic of the analysis, and let us look at your wireless environment. If you can eliminate wireless signal as an issue, then the issue
has to be with the router's settings.
Easy: Look at a picture to determine if a problem exists
Hard: Tinker with settings for hours and hope to find the 'perfect combination'
With my suggestion you lose nothing
and run a strong chance of fixing a really easy problem. Always start from easy and work your way to hard.
