Some major issues on a RB5009:
- 2.5G link does not work well at all, I’m on 2G U-Verse via a BGW320-505 linked at 2.5G. It causes about 1/2 bandwidth on 1G hosts, and on 10G hosts seeing as bad a 75% reduction in speed.

- Major issues with IPv6 in certain scenarios. It seems Linux based hosts (Synology for example) with everything standard, MTU 1500, etc are seeing 25-50% packet loss. On a 10G or 1G link download is around 250Mbps and upload around 25Mbps. The same on macOS 1G link I get gigabit both ways.
I’m shocked at the quality of the RB5009 ![]()
