<DIV>I think I'd first determine if the problem is with the wired speed of the
Internet connection.</DIV>
<DIV><BR></DIV>
<DIV>I'd try to determine speed of wired connections at the demarc point and
at the access points and every segment in between that has a switch or router
segmenting it.</DIV>
<DIV><BR></DIV>
<DIV>I'd check to see what the wireless is using for radio protocol and
frequencies:</DIV>
<DIV><SPAN class=Apple-tab-span style="WHITE-SPACE: pre"></SPAN>802.11n with
802.11a compatibility</DIV>
<DIV><SPAN class=Apple-tab-span style="WHITE-SPACE: pre"></SPAN>802.11n with

5GHz</DIV>
<DIV><SPAN class=Apple-tab-span style="WHITE-SPACE: pre"></SPAN>other?</DIV>
<DIV><BR></DIV>
<DIV>I'd scan the wireless channels looking for interference.</DIV>
<DIV><BR></DIV>
<DIV>I'd check to see if they have configured their LAN subnet appropriately -
avoiding typical problematic subnets (problematic because a lot of devices
default to these subnets)</DIV>
<DIV><SPAN class=Apple-tab-span

<DIV>
<DIV><SPAN class=Apple-tab-span style="WHITE-SPACE: pre"></SPAN>...</DIV>
<DIV><BR></DIV>
<DIV>I'd also perform a wireshark scan if I made it this far and didn't find
anything yet. I'd want to analyze the traffic to see if there are some high
traffic or nefarious issues.</DIV>
