Hi all

I have gone through many threads and all end with the solution of the new firmware (1.2.3 Build 20230603 rel.46473(4555)) being the fix.

I am currently using that firmware.

I have two inter-related issues:

1. WAN drop outs.

This is a router issue, similar to the teardown issue, my DHCP lease time with the ISP is lost.

2. LAN drops out on WAN droppage

Once the WAN goes down, all LAN ports go down too, this includes my desktop, NAS and TV. Typically I'd know my net was down as anything im streaming from my NAS to my TV would drop too. 

This is all internal, no reliance on internet for the stream.

Initially I thought it was my ISP (LAN was odd though), after troubleshooting with them it was isolated to an internal network issue. I changed my 5 port switch (made no sense to me that downstream hardware could be the cause), however my ISP said it was showing a different device connected to the internet instead of my router (possibly due to MAC clone on the TP rather than default). I was considering changing my NAS, however I get the issue even when it's not plugged in. After reading some old TPLink forums, I figured it was the router.

Any ideas would be great. I also had this issue with my previous TPLink, I thought it was old so I bought a new one, but it seems its a TPLink issue. Regret not going another brand after having this headache.

Thanks
