Internet cuts out several times a day
Internet cuts out several times a day
So I got the ER605 and also the ER7206 for my home network with a domain controller, exchange, and some vsphere lab work. Everything with the local network is working well however every few hours, sometimes just a few mins, the Omada Controller software on my laptop will show a red error in the log with messages like:
[SFP WAN] of ER7206 is down or [WAN] of ER605 is down (depending on which router I try).
I used my ISP's SFP module and inserted it into the ER7206's SFP port. When I tried the ER605 I used the MC220L SFP converter and plugged it into the WAN port but it doesn't matter which one of these I use it's the same problem every day. The internet still cuts out for a minute then it's fine again for a bit.
Ping -t 8.8.8.8 confirms the issue when it goes down otherwise no dropped packets and the performance is as expected until then. So it's not the Bell modem/router and not the ethernet cable. The only common denomitor is I'm using these two TPLink routers (I first got the ER7206 then in case it was faulty I got the ER605).
I thought maybe it's my ISP modem (Bell Home Hub 3000) so I put that back in the network and the internet is working without issues. I'm using internet vlan 35 just like many others that bypass their Bell HH3000 and they have no no such issues.
I've tried all I can think of including cloning the modem's MAC address although that shouldn't be required. Also tried different public DNS servers and experimented with MTU's.
Anything else I can try before I return these TPLink routers and get something else? I'm running out of time if I want a refund.

@shberge Thank you for that. Yes I noticed that it seems to happen when I rename clients (from MAC address to user friendly name) but I wasn't sure since there's a small delay by the time it's logged. However, since I started being suspicious of this I stopped making changes and waited to see if it would happen again. Sometimes not for hours but it does still happen.
Should I downgrade to v4 then? I need it to be rock solid stable if I'm going to keep one of these routers because if it is a bug then I can't have this problem and wait for who knows how long before it's fixed. That would affect too many clients for too long.

Did you access the Omada Controller via localhost or via omada cloud website (https://omada.tplinkcloud.com/)?
When you see the red error "WAN is down" in the log, did the Internet connections drop out on all the devices actually?
Would the Internet always drop out for 1 minute, and then recover automatically itself?

Are you using the Omada Controller v5.0.29? Kind note that the Config file from higher controller version may be incompatible with lower controller version. If you downgrade the controller from v5 to v4, you may need to reconfigure the network for use.
I'm not sure if the issue has anything to do with the controller yet, further investigation will be needed. If you decide to downgrade the controller for a try, I'd suggest you save a copy of the current Log file and Backup config file before you do that. The R&D team may be able to address the issue with the information.

@Fae Yes I'm using the latest v5.0.29 controller software. Correct, I lose internet on all my devices for about a minute then it automatically reconnects. I changed the setting for the default reconnect interval value from 10 to 2 seconds assuming it would reconnect more quickly but I don't think this has any effect. I believe it took the same amount of time even when it was 10 seconds.
I access the Omada controller software via localhost as per the default installation on my Win'11 laptop.
I don't really want to downgrade just for the hell of it but if TPLink believes there's bugs that may be causing this issue in the current version then I will try it. Just as I don't want to return the product as, other than some of the bugs/issues, I really like it.
Let me know what should be my next course of action. If you'd like me to grab the logs I have now let me know where they are or what you want me to zip up and where to upload.
A couple of hrs ago I removed my Bell modem/router and put the ER605 back with the SFP module from the Bell router into the MC220L converter and then to the WAN port. Like before, so far so good but we'll see how many connection drops in the next 24 hrs...although this time I'm not touching a single setting in the Omada controller unless I really have to. And I'm going to leave it at v5.0.29 for the time being.
Keeping my fingers crossed that it's a bug in the Omada software as I believe TPLink can fix that in a reasonable amount of time. Perhaps a quick fix before fixing any other bugs because losing internet intermittently is a critical issue. We should not lose internet connectivity when changing settings in Omada that should have no effect on the connection.

@Fae Thank you. Btw, so far after about 12 hrs no internet drops since I started using the ER605 again with the same setup. Only difference now is I'm not changing anything in the Omada controller software. I just check in on it once in a while and just see the usual errors from time to time:
ER605 detected Large Ping attack and dropped 28 packets. |

@Fae For the most part it's good. However, there's definitely a bug in the controller software v5.0.29 because when I rename a device to a more friendly name I get the WAN port is down message and my internet disconnects for a moment.
Also, if a device has a hostname (and most of mine do) it should automatically use that as the device name instead of the MAC address. For most of my devices it won't do that hence why I keep having to rename them causing the internet to go down.

@shberge Thanks. I just upgraded as per the instructions. Right away the first entry logged was [WAN] of ER605 is down :-( and I didn't even change anything yet.
Will try to give it some more time to see if this will continue to be a problem but it's not looking good so far.
