Hi,
I'm trying to upgrade DD-WRT on my TPLINK TL-WDR4300 v1 from r24461 (June 2014) to r33006 (Aug 2017).
I downloaded the tl-wdr4300-webflash.bin.
I did the 30/30/30 reset, I got the "change password" page and then tried the upgrade via WebUI.
Here i get the message "upgrade refused". I then tried it via TFTP, which can't seem to establish a connection.
I then erased the NVRAM via telnet and tried the upgrade again, again failing.
Trying to upgrade to an older version first (e.g. December 2014) doesn't work either.
Does anyone know what I could do to convince the router to upgrade?
The reason for the switch is to establish the connection between the computer and the switch before booting the TP-Link router. Otherwise, you will most likely miss the TFTP window (the link will not be established in time). _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware?

Just buy an old router like a Linksys WRT54G2 or something very old like that. A switch will be much more expensive then a used very old router like that. In the US try Savers and Canada - Value Village or Salvation Army. In other countries just go to a second hand store that sells electronics and look for any old router, most Linksys from the wrt days (2006) that look similar to the attachment are supported by dd-wrt.
so I tried it with a switch between the router (.86) and my PC (.66).
I booted the router into the recovery mode and started the tftp client from my PC.
As you can see in the attached wireshark screenshot, .66 sends tftp write requests to .86, while .86 sends tftp read requests to .66.
Whenever a read request is sent, I get a ICMP Destination unreachable (Port unreachable) code.
From what I understand (and it's not much in the networking field), this means that .86 is trying to reach a nonexisting port on .66. But this port should be open because of the running tftp command, correct?
I found this thread on StackExchange which looks similar to my problem, there the solution was a setting in the server's tftp config.
Can that solution be applied to my problem?

By the sounds of it your switch is not setup correctly. It should basically just be a way to connect 4-5 ethernet cords together, to share files, no internet.
What is the ip of the switch?
Is the DHCP turned off on the switch? It should be.
Firewall on the switch, should be off.
Follow the switch wiki page I linked to above.
As for the ICMP requests from Wireshark, don't worry about those yet. Just get the switch setup correctly. _________________ Before asking a question on the forums, update dd-wrt: Where do I download firmware? I suggest reading it all.

Hey,
I'm using an actual unmanaged switch (a TP-Link TL-SG1016D), not a DD-WRT substitute. I don't think there's anything to configure on that switch.
Do you think it would work better using a DD-WRT router as switch?
I just had the idea that maybe the switch got confused with the different MAC addresses for the .86 IP since I had the router using that IP in normal operating mode and the bootloader used that IP with a different MAC.
But giving the router the .1 IP in normal mode had no effect. Still same as above (I did restart the switch after changing IPs ).
Also I can browse the internet with the switch in between my PC and the router, so I guess they can see each other. Or do you mean something else by that?
