Why does opkg not work in PandoraBOX on Xiaomi Mi-router mini? How to get 5GHz in pure OpenWRT?

Question

Network administration

Colleagues, please tell me the answers to a number of questions.
I am the owner of the Xiaomi Mi-router mini device, which I flashed on PandoraBox-ralink-mt7620-xiaomi-mini-squashfs-sysupgrade-r512-20150309.bin I also installed
pure OpenWRT, which I prefer, but there is no 5GHz module, to my greatest sorrow.
The questions are:
1. When updating the list of packages, I get:
DownloadingHttp : //downloads.openw...ages/base/Packages.gz.
DownloadingHttp : //downloads.openw...anagement/Packages.gz.
DownloadingHttp : //downloads.openw...dpackages/Packages.gz.
Downloading http://downloads.openw.../packages/Packages.gz.
DownloadingHttp : //downloads.openw...s/routing/Packages.gz.
DownloadingHttp : //downloads.openw...telephony/Packages.gz.
Collected errors:
* opkg_download: Failed to download http://downloads.openw...ages/base/Packages.gz , wget returned 8.
* opkg_download: Failed to download http://downloads.openw...anagement/Packages.gz , wget returned 8.
* opkg_download: Failed to download http://downloads.openw…dpackages/Packages.gz , wget returned 8.

* opkg_download: Failed to download http://downloads.openw...s/routing/Packages.gz , wget returned 8.
* opkg_download: Failed to downloadHttp: //downloads.openw...telephony/Packages.gz , wget returned 8
2. Is the removal of the luci-app-xunlei package fraught with something?
In general, that's all. You just need xl2tp for the damn Beeline and the necessary normal package update, and here is such an ambush.
Or can someone tell me how to get 5GHz in pure OpenWRT? I'd be happy :)

Answer 1

Try: downloads.openwrt.org.cn/PandoraBox/ralink/packages

Answer 2

As far as I understand, the repositories have moved now it looks like this
src/gz 14.09_base downloads.openwrt.org/snapshots/trunk/ramips/mt762...
src/gz 14.09_management downloads.openwrt.org/snapshots/trunk/ramips/mt762. ..
src/gz 14.09_luci downloads.openwrt.org/snapshots/trunk/ramips/mt762...
src/gz 14.09_packages downloads.openwrt.org/snapshots/trunk/ramips/mt762...
src/gz 14.09_routing downloads .openwrt.org/snapshots/trunk/ramips/mt762...
src/gz 14.09_telephony downloads.openwrt.org/snapshots/trunk/ramips/mt762...
The oldpackages folder has disappeared, but the openwrt folder has appeared
By the way, I am the owner of the same device, and just recently received it. Did your network reception drop after wpa2 encryption was set?
