I have a weird one here. I’ve searched and can’t find anyone or any mention of this type of issues elsewhere, but if I’ve missed it please let me know.
I have a CCR1036 that I use as our Core router. Recently we’ve been noticing slowdowns everywhere. So I’ve ran some speed tests using the built in MT Bandwidth Test. I could only get 50-60 Mbps from the CCR to any other router, even a RB493G that’s directly connected via cat5 and linked at 1Gbps Full.
If I run a speed Bandwidth Test from the RB493G to the CCR1036 I can pull 140 Mbps (TCP), but the other way 58Mbps max.
From here I wasn’t sure I could trust the built in Bandwidth Test, so Loaded up iperf on a laptop and a server directly connected to the CCR1036. Same result, if I go through the CCR1036 I get 50-60Mbps.
I’ve checked Queues to ensure they aren’t the culprit. Checked firewall rules, mangle, queue tree, etc.
I’m at a lost.
The CCR is running 6.18 The firmware is 3.09 but it looks like I can upgrade to 3.18. I’m unable to find a change log for the firmware, and I’m unsure rather that would have any effect on this. I’m also considering upgrading to 6.20. Unfortunately with this being our core router I can’t just run these upgrades. I’m hoping someone else know what’s change on the firmware side and might have a better idea if it would solve this.
Any help, ideas, suggestions on this would be appreciated!
