I have OpenWrt running on a Linksys WRT1900ACS for quite a while now (currently on 19.07.2 ) and am planning to replace my other Wifi units (AVM FritzBoxes and Linksys E1700 (unfortunately unusable with OpenWrt) with more OpenWrt-capable hardware.
I've ordered a TP-Link Archer C7 v5 (AC1750) some days ago, installed OpenWrt and tried a lot to get it running smoothly. I am trying to set up 802.11s ("mesh") when getting 2 more devices, but currently I am struggeling with setting up the first one correct. It even fails to work properly itself, something I did not experience with the Linksys device.
Problem on TP-Link Archer C7 v5:
opkg update fails with
Failed to establish connection Failed to download the package list from http://downloads.openwrt.org/releases/19.07.3/targets/ath79/generic/packages/Packages.gz regardless if it is connected via WAN or one of the LAN ports. If it is connected to the WAN port, I do not have internet access on my connected notebook (also LAN), but https://openwrt.org/docs/guide-quick-start/troubleshooting_internetconnectivity states that the WAN port should be used.

Because I want to set up mesh / 802.11s later (based on this guide (German)) I have removed the 2. VLAN, WAN & WAN6 interface. I have also installed
ath10k-firmware-qca988x kmod-ath10k wpad, according to OpenWrt 19.07.2 service release.
Currently I am trying to understand what I misconfigured, so e.g. opkg is unable to connect, the next step would be setting up 802.11s...
Thanks in advance for any help!
