UPDATE 2: ISP enabled fasttrack on their end and it solved the issue.
I have been very happy with my hAP AC for quite a while (few years), until last week.
Since about last week the LAN to WAN and vice-versa throughput has been gradually dropping until it hovers between 15 and 30 Mbit/s.
I have excluded cables, WAN itself and PoE.
The problem is very peculiar as if I change any settings in webfig or CLI relating to the interfaces in question (eg. flow control or ) the speed resets back to max.
The WiFi results are not conclusive, some devices are slow some are fast.
If I reboot the device the speed comes back to normal and in about 5 minutes drops back.
This is not ISP issue as testing directly leads to consistent results.
Things I checked so far:
1) IP is assigned to the bridge
Code: Select all
192.168.1.254/24 192.168.1.0 bridge
3) Firewall first forward rule is fasttrack
Code: Select all
chain=forward action=fasttrack-connection connection-state=established,related log=no log-prefix=""
5) The SoC temp is around 42-46'C
6) Cooling has no effect on the slowdown.
7) Running version 6.45.2 (same problem with version 6.43.8)
8) Changing bridge protocol mode has only temporary effect (after about 5 min it slows down again).
9) There is nothing in the logs to indicate any problems.
Is this a case of bad hardware? What would be routerOS equivalent to Linux `dmesg` command?
What am I missing?
