Hi all
I’ve a Mikrotik 2.9.10 configurated as bridge on my tower. In this machine I’ve 2 wireless cards: one 2.4Ghz card doing AP and one 5.8Ghz card doing PTP with my office.
My customers are complaining that MSN disconnect all time and that the MSN file transfer is very sllow.
What’s happen? How can I correct this problem?
Thanks in advance

Do you have pppoe?
no cibernet, I don’t have pppoe
does the msn messenger works over http proxy? or directly connected through tcp?
anyway I prefer to use natting to solve this problem
Your transfers go through microsoft’s MSN servers. Which i -think- are somewhere i the US.
UPnP for NAT’ed gateways. UPnP require L2 access from clients to UPnP supported NAT gateway.
Hi marron, I don’t use proxy… I use the standart form of the msn connection.
All my clients are using Valid IPs.
Thanks
Hi sten,
The problem with speed is between 2 clients of my networks that are on the same AP. If one client registrated on the AP1 send a file to a client registred on the AP2 the speedy is good.
What’s UPnP??? Why do I need to use it???
I’m not using NAT… all my clients are using valid IP addresses
Thanks

try testing the connection from msn messenger tools … test tcp connection…
I use upnp for voice n webcam …
The MSN connect but it disconnect and reconnect constantly…
What’s upnp?
Thanks again
Is this in the same tower where you’re having P2P issues?
I had problems with MSN disconnecting that were related to bittorrent clients eating up all bandwidth, and therefore the disconnections (not exatctly related to MSN but that would also go out)
Hi stuntshell,
Yes! It’s in the same tower!
Some time ago I had same problem with MSN disconnecting
I find that the problem is, a lot of my clinetns use p2p (bit torent) wich make me a lot of problems
bittorrent eating up all avelible connections to the internet.
There is no hope just tell tham for 3-5 days not to use p2p and see the results
for exp: Bit toren can work on port 80 and u can’t block this port.
My policy if i find someone using p2p I m disconnecting him from network 
That’s exactly the problem, bittorrent eating up the bandwidth, but not the propper resolution. One should implement p2p queues to control how much bandwidth should be allocated to P2P, no matter what port they use, MT is smart enough to track and shape them.
A good policy is to control P2P by days and hours, so your clients can still make use of this protocol, specially when no one else is utilizing the network.
Hi Dufol,
I belive that I’ve the same problem that you had. But I can’t disconnect my customer because I’m selling the Internet access to him.
Do you have another solution?
Thanks
Hi stunshell,
I’m doing the QoS control, but I’ve problems with MSN exactly thus.
I think that the problems is not the bandwidth usage, because I’ve problems with MSN when the bandwidth usage i low. I think that the problems is with the Packets per Second and the number of connections that then P2P softwares open.
Regards
If you’re implemented QoS then create a rule for MSN (port 1863) giving it better priority and see if it fixes. I seriously believe this is related to something else, start sniffing these packets and see what you can come up with.
Universal Plug and Play, as others have suggested, would do you good if it were a NAT environment, which you’re claiming isn’t.
I just have a rule to priorize the MSN…
I’m not using universal plug and play because I don’t do nat for my customer… all customer have a valid IP address.
Thanks
OK, so You want both p2p and all other traffic?
Then mangle p2p, limit the bandiwidth and priority to 8 in queue tree.
For MSN do magle, change TOS to 16 and give priority 1 in queue tree.
Cheers m8 
P.S. Did you replace prism card?
I tried to make mangle for msn, but no success to do that, please write this code somebody. thanks
just one rule to prioritize something would have the exact opposite effect, as all the unqueued traffic goes as highest priority. you need a second queue for everything else with low priority.
