I think I'd first determine if the problem is with the wired speed of the Internet connection. 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. I'd check to see what the wireless is using for radio protocol and frequencies: 802.11n with 802.11a compatibility 802.11n with 802.11b/g compatibility 802.11n only, 2.4GHz 802.11n only, 5GHz other? I'd scan the wireless channels looking for interference. 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) 192.168.1.0/24 192.168.10.0/24 ... 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.
