Had similar problem. Was running RouterOS 4.4 successfully for 2 weeks in NSTREME mode. All of sudden got alot of disconnects and bad quality and througput. Link started dropping about every 10 minutes (but only under big load). Seems to be fine when not being hammered. Downgraded to RouterOS 3.30....

clock problem was fixed twice... in 3.16 and major in 3.18 release. it was November 5th, 2008 and January 9th, 2009. No more entries in changelog about updating drivers or kernel. Chupaka, it was a year ago. Look at the kernel.org changelog. Is't long as toilet paper ;-) Suriesly, I hope that someo...

I meant, MT can't fix it until it's fixed in the Kernel =) clock problem was fixed twice... in 3.16 and major in 3.18 release. it was November 5th, 2008 and January 9th, 2009.

I remind you that it was a bug in the past and you fixed it... *) updated drivers & kernel - fixed fast clock issue on x86; as far as I can see, it was fixed rather by kernel developers than by MT itself... yes, but ROS is not free, open source, GPL project so we can't do it by ourself right ?

it's no hard to figure out that MT is not interested supporting x86 platform becouse of cracking ROS and ROUTERBOARD sale. not interested? for me, RouterOS on x86 works fine. and if for a few users high-precision clock works faster, and for some of them simple upgrade of BIOS solves the problem (th...

see http://forum.mikrotik.com/viewtopic.php?f=7&t=34103&start=0&hilit=x86+bios+clock thanks for this....yeap, it's always hardware problem.....;-) in 3.15 it was a hardware problem too ? no, it was fixed. it's no hard to figure out that MT is not interested supporting x86 platform becou...

upgrade the BIOS?..

BIOS is the lastest ver but this is not the point.

2.x and 3.x is running without any problems.

INTEL 815 + Pentium III

It was fixed in 3.16 and now is back.

update:
not only 4.4... all 4.x versions !
I returned to 3.30 :/

"As soon as you enable use-ip-firewall in bridge, there is lots of things changed from interface, actual interface and port point off view - If you will create your mangle/queues based on IP addresses, not interfaces everything should be fine. Also,please, check that Xen package is uninstalled....

When use ip firewall is disabled queues are ok.
It isn't sollution and remember everything was all right before use ip firewall for pppoe was added.

I noticed this problem for other platform too (RB600 RB433) but not always.

I have a problem with pppoe dynamic queues at x86 since use ip firewall for pppoe was added. I think problem was noticed in http://forum.mikrotik.com/viewtopic.php?f=2&t=32992 but with no answer. I was mailing with normis due to support Ticket#2009061566000527. Normis : There is no difference if...
