Hi, Just got my VIP 5 with L7 router.
Been experiencing slow connection speeds and congestion with HyypTV on
Called customer support and they advised to cahnge few settings

In Manual Wireless setting,
Disable/Unmark : Enable Auto Channel Scan
Wireless Channel : 2.462Ghz / Channel 11
Channel Width : 20 MHz

will monitor the speed after this..
hope this helps.
