+ | With CTF enabled, the router starts to send out transmission frames as soon as the full packet header has been received. However, the router relies on the client device to tell it whether the data is corrupted for resend. This restriction can cause problems with a few common home uses. Note that enabling CTF will disable QoS and Bandwidth Limiter. This is because the switching part of the packet bypasses parts of the standard Linux iptable chains. | ||
