I just upgraded my router a few days ago to v1.9.0 (from v1.8.5) and seem to randomly have some packet loss.
Pinging a few domains (and using mtr) seem to all point at my ERL being the issue. I started debugging this today and when connected directly to the modem (Surfboard SB6141) everything is perfect. Connected directly to eth1 (or eth2) and I get a decent amount of packet loss.
Network config:
- Comcast ISP
- Surfboard SB6141
- ERL:
- eth0: WAN
- eth1: Wired LAN 172.16.0.1/24
- eth2: Wireless LAN 172.16.1.1/24
- eth1 is connected to a Trendnet 8 port Gigabit switch
- eth2 is connected to a Ubiquiti AC access point
I just swapped the ERL out with this old Netgear WNDR3700-v2 router I have running OpenWRT and there's no packet loss when connected directly via ethernet or over the same access point which I connected to one of the 4 LAN ports. I also tried to restore to the factory config on the ERL by holding the reset button until the light was solid on eth2 and reset up via the Basic Config Wizard the same setup listed above.
Even with only my computer plugged into the eth1 port and the eth0 connected directly to the Surfboard modem, the packet loss resumed.
Thoughts on what I should debug from here?
Perhaps rolling back to v1.8.5 to verify that version isn't seeing the issue would work?
(Not sure if that's as easy as uploading that firmware or if there's a specific procedure).
Of course, happy to provide any other info that might help someone out there.
