Upgrading from 18.06 to 19.07.3 on TP-Link 1043ND

openwtruser435 · June 20, 2020, 8:20am

Hello,

I have a TP-Link 1043ND with 18.06.
Now I read in the changelog for 19.07.3, that the architecture has changed (from ar71xx to ath79).

I have set up Wireguard on the Router, which I would like to keep it's settings, if possible.
I also set up a Swap-partition on a USB-stick.
The Router is in it's own NAT.
My primary Router(Which I use only as a Modem) has 192.168.1.1
My OpenWRT Router 192.168.2.1

Would upgrading affect any of that?
Should I remove the Swap first and do I need to re-configure the Wireguard-settings afterwards (I would like to avoid that)?
Installed WG Version is 0.0.20181119-1.

I also tried to update packages today, but it does not work:

DNS seems to work, although very slow:

On my PC I don't use the Routers DNS-Server (I don't remember why, maybe there was a Problem)

Try resetting to defaults and manually configuring your router. In general, this is the recommended strategy when you upgrade across major releases (maintenance releases are almost always okay to keep settings). More importantly, certain config files are not compatible across the ar71xx > ath79 transition (the network and wireless files in particular). Unless your configuration is particularly complex, it should not take long to recreate your previous setup.

Okay, so the way to go would the to do a Firmware reset and then directly flash the factory file for 19.07.3 or the sysupgrade one?
My Router is my DHCP-Server, so my PC will no longer get an IP, when I reset and reflash it.
What IP is it then defaulting to or what IP do I need to set my PC then to manually to be able to access the Webinterface/SSH?
Because I remeber hte last time I upgraded I could no longer access the Router and it took me some days of fiddling to be able to gain access to it again.

Do you know which files I need to backup for Wireguard, so I can just copy them back onto the new Firmware and it works and I don't need to change anything on my Wireguard Clients?

I was also thinking about buying a VPN-Access (for Example WeVPN).
Is it possible to configure the Router, that all traffic except manually added sites (for example Netflix) will to through the VPN? Or do I need access to a Proxy to be able to do that? But Proxies usually do not support all protocols right?
