Jetway 3 eth riser board

Thu Nov 15, 2007 1:46 am

I just installed Mikrotik on a Jetway Hybrid mini-itx board with a 3 Gig Ethernet riser board (P/N J7F2WE1G5D) and to my dismay, it seems that the drivers for this card are not yet in the stable release. see: http://www.mail-archive.com/wireless@wi ... 12741.html

Any chance that they are in version 3? It would be nice to have a 4 Gig E board running Mikrotik.

You are in the same boat like me...
Look at:

I hope MikroTik stuff is investigating the problem although i have not
heard a word from them

yup - had the same problem, and feedback from MT is that they will not be implementing these drivers in 2.9

Unfortunately, v3 is the only version at this stage that will support this.

I must say, I have experienced disappointing performance using Jetway miniITX boards - seems to be IRQ related. I see the Jetway boards only support up to IRQ 14, whereas other Intel boards I have used went up to around IRQ 18.

I read your thread but I am using the Hybrid series with 1 main Gig E port and a three Gig Ethernet riser card. I am not running anything in the PCI slot. The main ethernet port was detected and seemed to work well but the three eth riser cards interfaces were not detected. Upgrade to version three now shows the cards but I have yet to configure and test. I will hook up all four at the same time and see If I can force a lockup.

Thanks

Currently (using rc10), the Main eth interface works, as well as two out of the three additional interfaces on the daughter board. ether2 (the first port on the daughter board) goes up and down like a pogo stick. The rest of the ports seem to work fine. I will play with it a little more and then move to rc11.

take a look if the problematic IFs share the same irq

I have not had success with those gigabit realtek chips (8169SC & 8110SC). I have that same jetway 3 port riser card on an OpenBSD firewall and the gigabit ports would lock up and stop transmitting, sometimes because they got overheated. They seemed to be more stable when connecting to a 100Mbit fast ethernet device instead of a Gigabit device and when I added heatsinks to the chips.

The worst setup was onboard Intel Gigabit on my workstation to the jetway Realtek Gigabit port on my firewall and then another jetway/realtek gigabit port on the firewall to a Mikrotik rb44g (also realtek gigabit) in a separate x86 mikrotik router. Both my firewall (jetway mini-itx + 3G card) and the x86 router with Mikrotik rb44g would lock up. I also tried my Intel workstation port connected directly to a rb44g in that x86 router bypassing my Jetway firewall, and the x86 router still locked up. I ended up replacing the rb44g's (3cards) with rb44's and running my jetway gig ports at 100mbit and putting heatsinks on the gigabit chips like the rb44g's, then it was mostly stable.

When I was at the MUM in Orlando, FL there was a rb44G-V shown on a slide and said it might be replacing the rb44g with a card using VIA gigabit chips instead. I was excited to see that a replacement product might be available in the future, but I have not seen any news about it yet.

If you buy another Jetway mini-itx board, avoid the 3 gig daughterboard. If you only need 2 gig ports, try the J7F5M series board instead of the J7F2 series like you and I used. The J7F5M has 2 Via VT6122 gigabit ports and seems to support the same set of daughterboards the J7F2's uses if you also want 3 extra 10/100 ports.

For the record my firewall used the J7F2WE1G2E motherboard and AD3RTLANG (realtek 8110SC) daughterboard running OpenBSD 4.1/4.2. That router is a 4u x86 machine with a Athlon 1.15Ghz Athlon MP processor and 3 rb44g's (realtek 8169SC) and now 3 x rb44's and 2 x 3com 3c905's running RouterOS v3.0rc3, I don't think I ever tried 2.9.x since it is my UserManager machine and wanted 50 active sessions instead of 10.

Sorry for the long story, but I wanted to confirm petecarlson's story of the ports going up and down 'like a pogo stick'. I should have posted a few months ago when I had trouble and found a little bit of a solution.

Funny thing about the Realtek gigabit chipset is, that it not even recommended
by MT themself. See their driver list in the manual (MT v.2.8 ):

http://www.mikrotik.com/testdocs/ros/2. ... erlist.php
RealTek RTL8169
Chipset type: RealTek RTL8169 PCI 10/100/1000Base
Compatibility:
    * RealTek RTL8169 Gigabit Ethernet (not recommended: may lock up the router) 
In the MT v2.9 manual it was removed after releasing the RB44G. Short time after the
new RB44G it was still there ... checked it because we could not believe they used that
chipset for their new PCB.

We use Intel and have never had any problems so far.

Freebird: This is no longer true, that is why it's removed from the manual. See this topic:

http://forum.mikrotik.com/viewtopic.php?f=6&t=6325

The drivers at that point were changed, solving the issue with these chipsets.

So it's ok tu use Realtek 8169 and 8110SC? Or we will have problems with ROS 2.9?
