Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.1.2 Build 20230210 Rel.62992

My router randomly disconnects from the internet. It will work fine, then will suddenly not have internet access.

 

The router is physically connected to two desktop PC, a television, and a WAP. (I know this device is meant for businesses but I'm using it at home anyway.)

 

This problem has worsened when I started using a new WAP. It's a Netgear WAX214 (AX1800) and is connected over a LAN port using DHCP. I used to get disconnects every week or so, but now it's every 1-2 hours. Sometimes just the WAP loses internet, but most of the time it's the router.

If you have an extra machine sitting around... Start a ping to the gateway and start a ping to google dns.  Lets confirm which one goes out.

 

By chance are you double nat'ed?  Is your ISP modem in router mode?

  @KimcheeGUN Thanks for the feedback.

No, I don't believe so. I did a trace route test, there was only private IP address (belonging to the router) before the request reached my ISP.

 

I should point out, since Tuesday when I made the original post I've been using an old, cheap wireless router instead of the new WAP. During that time, my router has not failed. But I don't see how a WAP would cause a router to just stop working...

  @Clive_A I tried updating the firmware, as you suggested, being sure to check the hardware version and region. However, the update failed with no explanation why. The failure message just said to "check the file".

Last time I had the "Update Failed" message was when I was downloading wrong version of Firmware (the device was described as Netherlands' and I was downloading Firmware dedicated to my - different - region).

The best option was to choose universal version of firmware.

 

Not sure if that helps in you case, just check it if you can.

 

Information about device's region I've found on it's box.

 

Cheers.

  @RaRu Thanks, but the version I'm referring to is the same as the universal one. @Clive_A had previously referred me to that one.

I checked the system logs, and this happened 158 times today prior to the router crashing/restarting:

 

DHCP Server allocated IP address 192.168.0.xxx for the client[MAC: 1a:2b:c3:d4:56:ef].

 

Is it normal? My DHCP lease time is 2 days and there are only 13 clients, so I don't see how it could be normal. What's happening and is it pertinent to the problem I'm having?

@Clive_A Thank you for pointing that out. I was able to run all of the firmware updates.

 

However, the original problem persists. Firmware updates did not have any effect.

 

Is the info in my previous reply relevant at all? https://community.tp-link.com/en/business/forum/topic/714582?replyId=1437936

As the problem is about the router, so I don't recommend any tests on the wireless products.

Will you experience a problem with the wired connection?

What's the network like? I would need a diagram with the IP specified on your diagram so I can learn if you have a fundamental problem with the setup since you have mentioned DHCP and another router in the context.

 

This does not look like a hardware or a software issue anymore. More like a config problem with your network. Or your ISP fiber/land line is not stable.

Run the ping -t to a DNS server that is available in your region. Let's see how unstable that is.

But all in all, I think it is no longer a problem with the hardware or the software. You can easily replace the router if you just purchased it from your retailer. I don't believe exchange a different Omada would resolve the issue at this moment.
