format: <WAN Info>:<DL Speed>:<UL Speed>:<DL Load>:<UL Load>:<LMD>
WAN Info: B0-B1: Link Status, B2: Symmetric Link, B3: At Capabity
   (encoded as two hex digits)
Downlink Speed: Estimate of WAN backhaul link current downlink speed in kbps;
	1..4294967295; 0 = unknown
Uplink Speed: Estimate of WAN backhaul link current uplink speed in kbps
	1..4294967295; 0 = unknown
Downlink Load: Current load of downlink WAN connection (scaled to 255 = 100%)
Uplink Load: Current load of uplink WAN connection (scaled to 255 = 100%)
Load Measurement Duration: Duration for measuring downlink/uplink load in
