i have setup and redone mt 3 times now, and each time the same result, the bridge works for about 45 seconds and then it just stops, the mt server still responds to pings, but wont pass data through. any ideas?
has anyone here encountered this before?
perhaps spanning-tree has found a loop?
could also be caused by some ethernet cards (buggy drivers?)
Could you give more details please?
How many interfaces did you bridge? Are they all wlan or wlan/ether?
i have 2 bridged both are ethernet. one is an rl-8169(gigabit card, but running at full duplex 100) and the other is the onboard one on an ECS K7S5A motherboard. other system specs are 512 pc2100ddr. 80gb hd, AMD Athlon 1700+
have you red what the device driver list says about r8169 ?
RealTek RTL8169 Gigabit Ethernet (not recommended: may lock up the router)
Some time ago I had this kind of NIC on MT 2.8.23 .. it was working pretty good except interface status monitor, where link had unknown speed, auto negotiation was unknown etc. And after upgrade to 2.8.24 just after the first data packet tried to pass through this interface, router stopped responding completely and, after some time (I think minute or so), crashed with kernel panic.
I haven’t tried to use r8169 on any version newer than 2.8.24, but anyway.. be careful 
ok, thankyou, i will try it with a different nic, i didnt see the warning, i just saw in the hcl that rtl8169 was listed.
thanks, will post back with results when i have retried with different nic.
awesome! that was the problem, replace it with a cheap dlink 100mbps card and now it works perfect. i will soon be installing mikrotik on my actual server(this is on my testing server now), and then i will be using intel pro/1000 cards.
thanks
Hehe, glad to hear 
You see, details solved the problem
Cheers…
I think the most popular new Dlink cards use the VT6105 Ethernet chip – though they have a Dlink part number printed on the chip. This is the same chip we use in the RB44 and RB500 and RB564. The VT6105 (or Dlink version) or the Intel Ethernet chips are the best.
