I’m using a Routerboard 532 with 64 MB of ram for my core router. I’m running software version 2.9.46.
I have the three interfaces called WAN, LAN, and WLAN.
WAN is connected to a 20/20 Mbps fiber internet connection (through a Cisco 3350)
LAN is connected to our colocation customers and internal servers.
WLAN is connected to our WISP network.
I have all three of these ports forced to 100 FD.
The problem I am having is that recently the router seems to be having some trouble passing traffic. My users will report slow speeds and I’ll check it out and I’ll see only 1.5 - 2.0 mbps in/out for speeds. If I reboot the router the speed tests will jump back up to 20 / 20 mbps.
The CPU usage is normally around 30 % and the memory usage is generally 18 M / 64 M.
The average amount of bandwidth we are using is around 2.3 Mbps / 1.75 Mbps using a 30 minute average. The average packets per second we are using is 412 pps / 391 pps using a 30 minute average.
Also, I’ve noticed that during these times of slowness I see “Errors In” for the WAN interface reported by Cacti. Upon rebooting the “errors in” go away and so does the slowness.
Does anyone have any suggestions on how I can resolve this issue?
Yeah, We’ve been experiencing these same types of problems for months now. Same thing on both a 532 routerboard and the 112 routerboards. We’ve upgraded to the latest beta, but no change really. Problem still persists.
These issues are only on our 900 Mhz system though. No REAL problems on the 2.4 or 5.8 Ghz systems. been a bit scared to attempt to do anything with those systems because we’ve had sooooooo many problems on the 900Mhz.
We’ll probably have to bite the bullet and change our 900Mhz system to Motorola Canopy is MK doesn’t get things right, SOON!
xxpansion, I remember your support ticket, but you never replied back to us with support ouput files, as well incorrect data-rate were used at your wireless router.
keefe007, do you have problems with WLAN or LAN interfaces clients ?
Do you have any other devices between WAN and Cisco router, as probably problem is located there, what is the configuration for WAN (Ethernet) interface at MikroTik router ?
When the slowness occurs it can be seen on both the WLAN and LAN interfaces.
The WAN is physically connected to a Linksys SRW224G4 used solely for port mirroring for ntop and snort. Both ports used on that switch are forced to 100 FD.
The WAN interfaced is configured like so:
MTU: 1500
ARP: enabled
Speed: 100 Mbps
Auto Neg: No
Full Duxplex: Yes
I also noticed for some reason I’m getting packet loss on the LAN interface. I’m seeing roughly 4% packet loss when I run a constant ping from a device connected to the same switch as the LAN interface.
