Hi,
can anyone tell me why I have problem with speed over 2.4Ghz/b link ?
Situation is : 2 MT, connection like WDS/L2TP/EoIP.
When I run Btest I get speed (TCP and UDP) about 3.8Mbps (one way) but when I look to graph of WIFI card I see about 1Mbps more then say Btest > 3.8Mbps on test / 4.8Mbps on wifi card … ?
Distance is about 4-5km, signal about -65dB ,PRISM 2.5 card (same on both sides)
Any ideas 
?

check if you are using the ip number of the wireless cel on the other side when you test, not the ip of the bridge or the ethernet-port.
secondly; EOIP consumes some bandwidth. Maybe that’s the difference between those two measurements.
Of course I am using IP of bridge because I am interesting on ,real transfer speed, and I need found why is this big difference.

1Mbps ??!?!?!
EoIP has to fragment 1500 byte packets to include the EoIP info in the packet. 1450?? byte packets will not be fragmented. So, sending one big and one small packets slows the wireless down some.
We can make it so that it doesn’t have to fragment the packet (it becomes a much more complicated protocol then). EoIP has become so popular, I think it will be worth the effort.
I will put this in the list of things to do.

ok, but another question : how I can efectively connect this two routers to use max bandwidth (it works as WDS but is not neccesary) and if is possible use bridge and crypted tunnel ?

I try send packets 1500,1450,1400,1300… size and each have the same result max. 3.8Mbps on Btest
