通过无线网络观看iptv（需简单英文）
When someone is watching IPTV, IGMP/UDPpackets start coming in the 0/35 PVC. The modem just dumps these on theLAN, and the client displays the content. Unlike you usual content madeof TCP or UDP packets, IPTV stream is made of multicast packets. Thosepackets are distributed to all machines on the LAN, not just the onewatching the program.What usually happens when IPTV is being watched, browsing on wireless clients locks up.
IPTV(multicast) packets are entering the LAN from TPG at a fast rate. Withthe wireless access point being usually bridged, the multicast packetsstart flooding the wireless network rendering the wireless networkuseless.
What we need to do is set the speed at which the multicast packets are sent on the wireless link.
Now, not all wireless access points have that feature.
If they do, there will be a setting called Multicast Rate. Set it to at least 9Mbit/s. Your mileage may vary. Try it up
Somepeople have reported that changing their wireless access point totransmit in 802.11g only, sets the multicast rate to 6Mbit/s. Incombined 802.11b/g the default multicast rate is 2mbit/s which isn’tenough.
However, this not the case with all access points and they don’t always behave the same way.
Please check the AP List page for a list of access points known to work or not work.
简单来讲一句话：限制无线网络的multicast rate，设置成9Mbps。
