If you are still having issues,
there are a couple of other troubleshooting tips. Pay attention to what
is slow in your network. Is it internally slow—transferring files among
computers, for example—or is it browsing the Internet that's slow? Is
streaming from one device to another painfully slow? Look into updating
firmware on all affected devices, or if possible adding a more powerful
USB wireless adapter to a slow laptop or notebook, if they are one of
the culprits.
If Internet access is slow, check to make sure you are getting near the
bandwidth promised by your ISP. Use multiple speed test tools such as speedtest.net, speakeasy.net, and AT&T's speedtest
to get different results to compare. Keep track of bandwidth at
different times of the day and night as well as weekdays and weekends.
Contact your ISP for further troubleshooting if you are not seeing the
bandwidth you are supposed to receive from your ISP.
