Model: Archer C80  
Hardware Version: V2
Firmware Version: Archer C80(EU)_V2.20_1.13.2 Build 230824

I encounter disconnections on the internet that I didn't have before with FW 1.10.0:

"

1 INFO 0days, 00:12:05, [wan]Wan ethernet port plug off.

2 INFO 0days, 00:12:06, [dhcpc]interface bring down

3 INFO 0days, 00:12:06, [wan]advanced ddns -wanChanged

4 INFO 0days, 00:12:08, [wan]Wan ethernet port plug on.

"

 

I would like to get a link to the older FW version (1.10.0 EU for the v2.20 version) so I can work without disconnections!

The issue was with "Internet Port Negotiation Speed Setting" configuration.

The default value is  "Auto Negotiation".

I chose 100Mbps full duplex and the issue was resolved.

 

@Sunshine, I don't see any option for 200Mbps. is it something doable? Maybe to add it somehow?

May I know how often does it happen? and will you see the log "[wan]Wan ethernet port plug off." every time when internet drops?

Based on the logs, the issue recovered within several seconds automatically, right?

 

Please try a different Ethernet cable to connect the router WAN port to your ISP modem, if still the same, it is recommended to connect a computer to the ISP modem directly with the same cable to test if it is stable.

 

In addition, since your current firmware is 1.13.2, it could downgrade to 1.13.x only, may I know if you updated 1.13.2 directly from 1.10.0? we could try troubleshooting the issue to locate the cause.

  @Sunshine 

It happens every 3-4 minutes, and the same logs appear every time it happens.

the link recovered after ~3 seconds each time, but it makes applications to hang more than that....

 

i tried different cables and everything, its definitely related to FW. i have another same router, used it when the FW was still 1.10 with the same gear of the previous router.

when i upgraded the FW on that router as well - started seeing the same issues!

 

the automatic upgrade process made sequential upgrades, not straight from 1.10 to 1.13, there were 2 or 3 in the middle.

i must get a link to 1.10 or 1.11 so i can use those routers!! otherwise i need to throw them to the trash.

Thanks a lot for the update, there is no 200Mbps option, but since the WAN port is Gigabit port, there should be 1000Mbps option, if your bandwidth is higher than 100Mbps, you could select 1000Mbps to see if it works.
