Slow iPhone 4S speeds on Home Fusion Broadband

I've been using Home Fusion for about 4 weeks now and it's been great.  However, I'm been experiencing a slow experience connected to the Home Fusion service over it's WIFI to my iPhone 4S.  I typically receive about a 200 MS ping and 1-2 Mbps download and a 4 Mbps upload rate when checked on the Speedtest app.  The down/up speeds don't bother me as much as the lengthy ping times.  Is anyone seeing this issue?

The lengthy pings are causing slower downloads and a slower overall experience on the iPhone. 

My other devices such as computers, iPad and Xbox connect fine with blazing speeds.  I've also performed that test over a couple weeks with the same result.
